It was 25 years ago today

32bit computing arrived to the masses. Although it’s incredibly frail by modern standards, Windows 95 did deliver on the promises of OS/2. Depending on your apps, and drivers of course. Although OS/2 did have int13.sys to pass disk calls to a special v86 machine which then used the disk BIOS to make disk access possible, Microsoft and IBM stopped short there, not going all the way letting OS/2 use MS-DOS device drivers. Windows 95, however could.

This was always the winning strategy of Windows, is that it relied on the incredible OEM driver support for MS-DOS. Of course this would also be a catastrophic weakness. From my personal experience being able to leverage ancient MS-DOS drivers also helped squeeze as much as possible out of existing hardware. Case in point, the NDIS2 drivers for the AT&T Starlan 1mbit cards worked fine under Windows 95, additionally you could lost just the lower level drivers, and 95 could then load it’s protocols on top of that stack allowing you to have a TCP/IP network over that 1mbit Starlan stack letting you telnet into your 3b2 (or setup SAMBA, and doing file/print sharing).

If anything the biggest flaw of Windows 95 was not installing TCP/IP by default. However unlike many OS’s of the time, Windows 95 did include LAN and dialup stacks. There was plenty great about OS/2, but it’s refusal to integrate networking into the operating system hamstrung things like named pipes, peer, and larger apps, as you would have to buy and license a stack of stuff to bring OS/2 up to where it should be, while NT and 95 were complete out of the box.

Windows 95 was an excellent bridge OS for the era, until OEMs finally got around to writing drivers for Windows NT. Once the mainstream could finally take that leap, and leave MS-DOS far behind. But that didn’t really happen until Windows XP.

That being said, the favorite thing is to run Windows 95 in a browser. I found the fastest and best, as it loads a short 6MB compressed core image, and you are instantly teleported to the 95 desktop.

Try it out, play some solitaire and enjoy!

Couldn’t reserve space for Cygwin’s heap

I have this old toolchain that relies on MSYS 1.0 from 20+ years ago. It’s great. I know others always love the newer, but I’m happy with this one.

Well this morning I wanted to rebuild some Qemu 0.90 thing and I got this fun error trying to run configure:

      0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x0, BaseAddress 0x71110000, RegionSize 0x440000, State 0x10000
d:\mingw\msys\bin\bash.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 0

What the heck?! MSYS uses cygwin? I guess I should have known. So the solution is to ‘rebase’ the DLL, as it tries to take a static ‘grab’ at some memory block, because…. I guess subsystems or loaded DLL’s suck?

I rebooted and got the same error.

So obviously it’s a lot more involved.

So looking the rebase I have is part of the Platform SDK. Maybe there are others.

D:\MinGW\msys\bin>"D:\MinGW\include\directx\Microsoft Visual Studio 8\VC\PlatformSDK\Bin\rebase" -b 0x50000000 msys-1.0.dll

REBASE: Total Size of mapping 0x0000000000110000
REBASE: Range 0x0000000050000000 -0x0000000050110000

And now I can run stuff again. YAY.

I’m sure this has been covered time and time again, but you know it’s mostly to remind me in another 20 years.

The lost history of PReP: Windows NT 3.5x and the RS/6000 40p

The following is a guest post by PA8600/PA-RISC! Thanks for doing another great writeup on that PowerPC that was going to transform the industry!.. but didn’t.

The history of the PReP platform from IBM is quite interesting, not only because of its place in the history of Windows NT but also the history of the PowerPC architecture in general. When the PowerPC platform was new, IBM (just like a few other vendors, notably DEC) had grand plans to replace the x86 PC  clone market (they helped create) with PowerPC. Of course thanks to various factors such as Apple’s refusal to play along, the launch of the Pentium Pro CPU (and the later Itanium disaster), and high cost, this plan never ended up panning out. Later IBM PReP machines were designed for AIX and Linux use only, and they were sold as regular old RS/6000 computers.

Still, Microsoft being Microsoft and willing to port their OS to literally anything hedged their bets and made MIPS, PowerPC, and Alpha ports of Windows NT (along with a PC98 release for Japan only). In the guest post about Solaris for PowerPC I made, I talked about the history of IBM’s PReP platform some more so you should go read that post if you want an initial rundown on PReP’s flaws and history. But I have learned a bit about the Windows NT port for PowerPC, and I discovered a rare version of it as well. By now everyone with a PReP machine (or PPC Thinkpad) has run Windows NT 4.0 on it, and if PReP machines are emulated it’s guaranteed this will be the second most run OS on it aside from AIX of course.

IBM also made a half-baked OS/2 port for PowerPC as well, and then there’s the previously mentioned Solaris port. All of these are rarities and it’s worth documenting. With how rare PReP machines are and their high prices on eBay when they do turn up for sale (or their tendency to be snapped up fast), I think it’s fitting to write perhaps the most in depth look at PReP hardware that anyone has seen.

Windows NT 3.51: “The PowerPC Release”

It’s commonly accepted that Windows NT 3.51 was the first release for PowerPC hardware and it was even called this within Microsoft. Featuring HALs for most of the early PReP machines including the Moto Powerstack, the rare FirePower machines built for NT (which used Open Firmware), the Power Series 6050/70 (and maybe 7248), and the unobtanium IBM 6030, it’s pretty much what you’d expect for a first release for PPC. It’s a polished, solid OS that’s arguably faster than NT4 on the same machine. Aside from the red boot screen (on my Weitek GPU), it’s pretty much Windows NT 3.51 but on the PowerPC. It’s like running NT 3.51 on MIPS or Alpha, it’s interesting but more software will likely run on 4 anyhow (especially on Alpha).

One interesting quirk of Windows NT for PowerPC is it does not report the CPU type of your machine. It simply reports “PowerPC” and what machine you’re running it on. It does not tell you that you’re running it on a 601, it tells you that it’s running on an IBM-6015.

Unsurprisingly Visual C++ 4 works on PowerPC Windows NT 3.51 as well. This is no shock, Visual C++ 4 was designed to work on 3.51 as well as NT 4.0. The same goes with many of the pre compiled programs. One advantage Windows NT 3.51 offers over 4.0 is that it is simply faster than 4.0 on the PowerPC 601.

There’s not much else about Windows NT 3.51 for PowerPC quirk wise that hasn’t been said elsewhere about NT 4. It runs in little-endian mode (one of the few PPC OSes to), it has 16 bit Windows emulation that’s slow, and it needs specific PReP machines to run. One interesting series of articles about the “behind the scenes” of the port worth reading is the Raymond Chen article series, and this discusses the quirks of programming a PowerPC 60x CPU in little-endian mode as well. It can be installed with the same ARC disks NT4 uses, and of course the same SMS and firmware disks will work. In fact QEMU at one time was capable of booting the IBM firmware image from these disks.

Here’s something I’ve found out from research however. There was actually a limited release of Windows NT 3.5, it’s been dumped, and it is a real operating system. It also requires a very specific model of RS/6000 to work, and one with a interesting history giving it a unique place among the PReP machines. While I was unable to make it work in the end, I did discover and document a lot of interesting features of PReP machines.

Enter Sandalfoot: The IBM 7020/6015 (and demystifying PReP machines)

To understand the HCL and weirdness of Windows NT for PowerPC (and why it won’t run on Macs), we need to take a look at one such machine it runs on. This is my RS/6000 40p, a machine that was given several brand names by IBM and used as a development platform for PReP software and operating system ports. This is also perhaps the most historically significant RS/6000 model from the era. While it wasn’t the first PowerPC RS/6000 (that honor goes to the 250), it was the first to use the PCI and ISA busses and it was a few months ahead of both the initial PCI PowerMacs and other PReP boxes. It’s also one of the few true bi-endian machines as just like other PReP machines, the MIPS Magnum, HP’s Integrity, and modern Power8+ machines it has OSes for both endians available.

In 1994 (presumably October 28, if the planned availability date is correct), IBM released the RS/6000 40p (announcement letter here, codenamed Sandalbow) and the Power Series 440 (codenamed Sandalfoot). Both are near-identical machines with different faceplates and boot screens. The RS/6000 ranged in price from around $4,000-6,000 and was designed to be an entry-level AIX workstation, bundling a copy of AIX with each machine. As an AIX machine it’s relatively slow and fits the entry-level badge quite well, but thanks to the 601’s POWER instructions it served as a transition machine over to the later 604 AIX machines. Unlike the later PowerPC 603 and 604 machines, it featured POWER instructions allowing it to run both legacy AIX POWER software and later PowerPC software. The Power Series was presumably sold to those wanting a PReP box for Windows instead.

Since IBM PReP hardware is so obscure and undocumented, I’m going to document this as best as I can being the owner of an IBM Model 6015/7020. The machine features a 66mhz PowerPC 601 (similar to that of the Power Mac 6100 and RS6K 250), PCI and ISA slots, and IBM’s “Dakota” PReP firmware (more on the boot process here). It uses an off the shelf NCR 53c810 SCSI controller, Crystal CS4321 sound chip, an Intel 82378 PCI bridge, and a NIC can be inserted into the ISA slots (mine has the famous 3com Etherlink III). The Super-IO chip is also off the shelf, and is a National PC87312VF. The clock IC is a Dallas DS1385S, a close relative of the Dallas DS1387 (with internal battery). At least some of the IBM custom ICs are the chipset ICs and those are also documented. A Linux 2.4 dmesg can be found here.

Mine is also maxed out at 192mb of RAM, however there are some solder pads for more and the chipset is limited at 256mb. This makes me wonder if the system was based on a reference design of some sort. There was an ultra-rare 604 upgrade as well, but considering how there are more 7248 and 7043 machines in the wild I can assume many customers just waited for that instead due to its superior AIX performance.

If the idea sounds familiar (off the shelf chips + RISC CPU) it’s because it was the very same idea used to create the two other non-x86 Windows NT platforms. The Microsoft Jazz MIPS platform most MIPS NT boxes were influenced by was infamously based on the same idea of a “PC with a MIPS CPU”. To a lesser extent, this was also seen on the DECpc AXP 150 and other EISA/ISA/PCI based Alpha machines designed to both run Windows NT and DEC’s own OSes. Crazy undocumented custom hardware and expansion busses were thrown out the window in favor of industry standards. In fact when I posted a photo of the motherboard to a chat full of PC nerds, they stated it looked remarkably like a normal PC motherboard. The whole industry would later adopt PCI and sometimes ISA on non-x86 machines to cut costs and reuse the same expansion cards.

The main difference between the RS/6000 40p and the Power Series variant is the boot ROM logo and chime. The RS/6000 and “OEM” systems used a boot ROM that featured the PowerPC logo and just a beep, while the Power Series machines featured a logo more closely resembling the PowerPC Thinkpads complete with the chime. One can boot firmware from a floppy as well by typing in the name of the ROM image in the prompt and pressing enter, and watching as it reboots once the firmware is loaded into RAM. Here’s a video I filmed demonstrating this, along with some other quirks including there being two SMS keys: F1 for a nice flashy GUI SMS and F4 for a text based SMS, along with F2 for netbooting (with the right NIC of course).

The Sandalfoot machines were LPX form factor machines, featuring a riser card and generic sheet-metal case popular with prebuilt machines from this era. The LPX form factor was wildly popular in the mid 90s due to its versatility, seeing use by both IBM and DEC for their RISC machines, various PC builders, and even Apple for the clone program and clone based Power Macintosh 4400. The Sandalfoot machines also drove home one of the core goals of the PReP project, which was to build a PowerPC platform using as many off the shelf and PC style components as possible instead of using lots of custom ICs like Apple did. I dug out one of my cameras to take a few high-res photos of the motherboard of this computer to illustrate this. Compare this to the motherboard of the Power Macintosh 6100 or even the 601 based 7200 and notice the bigger heatsink and use of fewer custom ICs (Apple loved those).

There were three main GPU options: the famous S3 Vision864, the Weitek Power 9100 (or P9100 for short) as a higher end option, and IBM’s own GXT150P. The S3 was the entry level GPU and the Weitek was a higher-end and faster GPU. The GXT150P is beyond the scope of this because it is unsupported on the other PReP OSes, only AIX. The other two video cards are essentially unmodified Diamond PC cards with the BIOS chips missing.

The Sandalfoot machines are perhaps the most important PReP machines due to their role in PReP OS development. Both OS/2 Beta 1 and Windows NT 3.5 were written for this machine in particular as it was one of the first PowerPC machines to support PReP and feature PCI/ISA slots, unlike the NuBus Macs released a few months earlier or the first PPC box: the MCA based RS/6000 Model 250. They also often shipped with the well documented and emulated S3 Vision 864 video card, a common GPU family in PCs of the time to the point where it was even included on some motherboards and emulated in too many PC emulators/virtualization programs to count (notably 86box/PCem). In fact it’s successor (the 7248) featured one soldered to the motherboard.

Windows NT 3.5: Failed Install Attempts

An oft repeated quote about Windows NT 3.5 for PowerPC is this one from Paul Thurrott’s Windows site:

Windows NT 3.51 was dubbed the Power PC release, because it was designed around the Power PC version of NT, which was originally supposed to ship in version 3.5. But IBM constantly delayed the Power PC chips, necessitating a separate NT release. “NT 3.51 was a very unrewarding release,” Thompson said, contrasting it with Daytona. “After Daytona was completed, we basically sat around for 9 months fixing bugs while we waited for IBM to finish the Power PC hardware. But because of this, NT 3.51 was a solid release, and our customers loved it.” NT 3.51 eventually shipped in May 1995.

I think a more accurate thing to write is that there simply weren’t many PReP boxes out in late 1994. Windows NT 3.51 supported the Motorola PowerStack series, the IBM 6050/6070 (and maybe the 7248, which came out in July 1995), and rare FirePower machines. Windows NT only features HALs for the 6015 (Sandalfoot/Power 440/RS6K 40P), 6020 (Thinkpad 800), and the 6030 (a rare IBM machine that likely was only sent to a few developers). By 1995, there were more PReP machines on the market and this made the NT 3.51 release logical. NT4 even supported a few servers, mainly the RS6K E20, E30, and F30.

Windows NT 3.5 was most likely a limited release for testing purposes on the Sandalfoot machine as it’s HCL file declares it as “Build 807” with a date of October 18, 1994. The date seems to be around a week or two before the first 40p machines at least shipped. Some more files were modified later on and the folders were created on November 9th, 1994. Hardware support is very barren, and the readme file even has a section dedicated to quirks of the 40p along with a list of supported software for the x86 emulator. This might have been considered a beta as well, as an announcement letter for the Thinkpad 800 (6020) explicitly mentions Windows NT and that this version might be a beta for developers. It also talks about a Windows SDK for it and a Motorola compiler used to build 3.5 software.

However the real problem for me has to do with getting a video card. Windows NT 3.5 for PowerPC does not support the Weitek P9100 GPU that came with many RS/6000 branded machines, and neither does OS/2 for PowerPC. It only supports the S3 Vision 864 and 928 video cards. It’s listed in the setup options, but choosing it causes a txtsetup.sif error. I’m going to assume that the development units came with the S3 video card instead. My box contained a Weitek card which works for AIX, Solaris, and Windows NT 3.51/4. I bought a card from eBay to use with NT 3.5 and the OS/2 port.

 The readme also features an ominous warning with the S3 video cards, that only revision B3 is supported and that 928 cards need 2MB of VRAM for anything above 256 colors. My revision of the card I ordered was B4, so I took the risk of seeing if it worked with my system. I also removed the ROM chip as the system initializes the video card itself and that having a ROM chip can cause the system to not complete the self-test or display video. As the IBM Weitek card lacks a BIOS, I did this.

Despite the scratches on the card from possibly coming out of an ewaste pile, the card worked fine in both a PC I inserted it in for testing purposes and the IBM system. I now had a 40p with a GPU much more well supported among non-AIX or Windows NT operating systems.

Anyhow, let’s talk about the install process in closer detail here. Windows NT for PowerPC installs in a similar manner to Solaris for PowerPC on the IBM PReP machines. First the floppy disk boots ARC, then when you choose to install it the machine copies the ARC bootloader/firmware to the hard disk so it can load it from there at each boot. The floppy disk can also be used to load ARC if the loader is damaged on the hard disk. Keep in mind, on IBM machines ARC is not stored in the ROM unlike on many other ARC capable machines so this has to be done. The Firepower machines do something very similar by using an Open Firmware shim, and unsuccessful attempts at emulating PPC NT have exploited VENEER.EXE to attempt booting instead of using the IBM firmware. It fails because they’re not emulating the hardware, just trying to find a quick way to just boot NT.

Once this is done, the installer loads up and installs just like every other NT install. It checks the HAL by reading the machine ID, what video hardware the machine has, and whatnot to prepare the installer. You need a IBM 6015, 6020, or 6030 according to the HALs it has and only the S3 video cards are on the HCL.

Or that’s what should happen. I first tried using ARC 1.51 as it worked for 3.51 and was greeted with a HAL error BSOD:

I first attempted to use older ARC boot floppies and I got somewhere, the BSOD changed to the classic 07b, and then I got nothing else. Using ARC 1.48 and 1.49 gave me this, I got some i/o error with ARC 1.46 (the first 3.51 ARC floppy), and any previous ARC floppy is most likely undumped. I’m assuming either the error is due to an ARC mismatch, a weird firmware mismatch/hardware revision mismatch, or some incorrect SCSI ID Solaris style. There might very well be some weird forgotten trick to making it work (maybe a Windows expert could dig through the files and find some weirdness), but I’m going to move onto another obscure PPC rarity:

OS/2 PowerPC Boot Attempts: Beta 1 and the Final

Recently the OS/2 Museum site dumped Beta 1 for PowerPC. It’s an earlier version of OS/2 for PowerPC that insists on a Sandalfoot machine with an S3 GPU. Unlike the other OS/2 PowerPC disc, it features a verbose boot featuring the kernel it uses. If you want to really see OS/2 for PPC working, try it on a 7248 or read this post about it.

This failed to boot, throwing up an error about mounting the disk or something. I did record it doing something at least however, an improvement over the Weitek which just does nothing at the PowerPC screen. I tried several things including removing the external SCSI CD drive and that didn’t fix much. It also declares 88c05333 an unknown PCI device.

So I decided to try the “final” build. The final build requires a 6050/70, and some people did get it working on the PPC Thinkpads. I decided to see what it’d do on my machine. Unsurprisingly it did absolutely nothing but give me a blank white screen and sometimes a 00016000 error (for a trashed CMOS). If anything the 6015 loves to trash it’s CMOS contents for absolutely no reason, especially when OS/2 is involved.

Anyhow this was very anti-climatic, as the OSes I threw at it found reasons to not work on it whatsoever.  I weeded out the GPU being at fault by testing Windows NT 4.0 and finding out that it works just fine with the GPU, however I seem to have fewer resolutions available than what the Weitek card allows. It did change the boot screen font, making me wonder if the red boot screen is a GPU driver quirk.

However changing the device IDs with OS/2 PowerPC Beta 1 got me somewhere, as I now got a screen about the HDD failing to write. I formatted the HDD to FAT using the ARC diskette, then I nuked all the partitions, but not much else changed. I’m not sure what the error means, but it was a letdown.

Unless these OSes require some long lost firmware, I’m wondering if there’s else that’s causing issues with installation. Either way, it was a letdown. Nothing I tried worked and I spent hours messing with everything from SCSI IDs to using different drives.

Sandboxie went GPL3!

I’ve been using Sandboxie for a long while to run all those questionable downloads on Windows. It’s a great light weight sandbox (as the name implies) for running random downloads, or even going to questionable websites as Sandboxie does a great job of isolating processes, and their filesystem access.

It’s not been all that cheap, but I felt it was worth it. I went to check to see how much it is as the conversation had come up on discord, and it turns out that Sophos had bought Sandboxie, and opened up the source code!

The downside is that there will be no further official development of the product. So I guess at some point I’ll have to break down and get a signing cert and re-build it if I want to keep using it.

Last version is locally mirrored here, as I understand it’ll be deleted soon enough.


Anglofying & running Japanese Lemmings for Windows

On one of my later trips I picked up this fun title, Lemmings!

And looking at the back of the box, what fun it contains!

Support PC-98, Epsons, IBM’s, IBM PC/AT.. Probably FM Towns as well

One interesting thing about 1995, is that with the rise of Windows 95, this marked the end of the specialized PC market in Japan. Just as WING/Direct X basically killed off the DIY driver/extender environment on MS-DOS, by being able to abstract the hardware it removed any meaningful difference between an EPSON PC vs a PC-98, FM Towns, or even the lowly IBM AT/386.

This being a Win32 includes both WING & Win32s. A perfect snapshot of an early Win32 commercial game circa 1995, as you needed to cater to that massive Windows 3.1 install base, although so many were rushing to Windows 95. Naturally this also means that the setup program is a Win16 app, once more again to preserve that bridge of the Windows 3.1 & Windows 95 world.

Well the obvious thing to do is just install it on a legacy 32bit OS, and what better than Windows XP?

Lemmings happily running under Windows XP via VMWare.

Now to run it on something like Windows 10, it’s just a matter of copying the WINLEMM.INI into %sysroot%, along with placing a copy of WING32.DLL into the %sysroot%\SysWOW64 directory and you are good to go!

Japanese Lemmings on English Windows 10

Sadly the character encoding in Windows is still really lacking and doesn’t render all that great. However that had me thinking as almost a decade ago I did find a demo of Lemmings for Windows. Could it be possible to just overlay the executables & DLL’s to produce an English commercial version?

Surprisingly the answer is yes. I wasn’t sure what to expect, but it’s as simple as that!

The game is mostly playable, some parts are just coded to run as fast as possible, as no doubt nobody was imagining 1+ Ghz machines. So the intro, warp & suicide are almost instant.

It’s something to keep the kids entertained for a day in recent events. It’s been a LONG CNY.

Cross compiling SDL 1.2.15 for ARM Win32

I was getting this fun error:

Which was NOT easy to track down. Thankfully while amputating and chasing the origin of GUID_Key, I ran across this:

I have read various texts that state you must

1#define INITGUID

And yes, you do!

In the file SDL-1.2.15\src\video\windx5\directx.h I just added it to the top, and now it’ll build the hacky DLL!

Maybe it’s something for Visual C++ version 19? I don’t know.

Anyway the advantage is now I have full audio for DosBOX!

Luckily updating binaries wasn’t too hard.

Congruent (Toolbusters) GCC 2.4.5 for Windows NT

Perhaps one of the more interesting, if not abandoned GCC ports.

It’s from 1994 (although they apparently had earlier), and it’s just enough binutils & gcc to compile stuff for Win32.

I stumbled onto the directory while looking for the source code to the ‘top’ program, which incidentally can be found here. In hindsight the name ‘top’ is pretty terrible, as looking at the ‘top program for Linux’, well you are going to find all kinds of crap, and surely not top.

The files gnu-bin.tar.Z and gnu-lib.tar.Z contain enough binaries for GCC 2.4.5 C/C++ and ObjectiveC, along with GAS and what purports to be a linker, although I think it just prints the flags to MS Link that you’d need.

And as mentioned in this post, by Juha Inkari, how on earth do you use this thing? Well thankfully in the future we have access to more stuff, so I decided to throw MinGW at it, and see what happens.

I’m using the Linker & LIBC from Fortran PowerStation 1.00 with the linker update.

There is no source diffs, patches, or anything really.

Is this useful? I suspect not. Thanks to RSXNT there is easier ways to get much older versions of GCC… Although I guess it speaks more so to this port using OMF objects.

Living with ARM for a week

So after the crazed purchase I made a few weeks ago, I returned from Japan, and was able to unbox and use the machine I’d been wanting for a while, a non x86 Windows laptop!

The NovaGo has a Snapdragon 835, and my phone, the ASUS ROG phone has the 845. Yes for this week, my cellphone actually has the stronger processor than my computer. Honestly this is almost an unthinkable situation! Although I haven’t been using my phone as a desktop substitute this week. It’s amazing how MS screwed up 10 on the phones, and Continium.

By default it comes crippled with this ‘S’ mode Windows, which hearkens back to the Windows RT launch, with the difference that it’s a quick trip to the application store to unlock Windows 10 Professional. It’s a free download as it should be, and it doesn’t even require a reboot!

Build quality isn’t so bad, the screen folds all the way back to make the machine into a ‘tablet’ although I don’t like that mode so much, it just feels wrong to wrap a keyboard around a monitor. However if you have rambunctious young kids, it’s great as when someone went running by me flailing their arms around like a while animal, when they struck the laptop the screen could easily fold back 180 degrees. Yay.

My first thing to do after setting up Office and VMWare VDI was to install the Linux subsystem, and Ubuntu. it’s exactly the same as it is on x86_64, which is great. And this let’s me have the best of both worlds, just like x86_64. As much as I dislike stumbling around with that aborted child of Pascal & Fortran (Python) at least I can run it under (mostly) Linux to get something close to like the production environment.

The C/C++ compiler is actually all cross tools. I wanted CLI only stuff because I like torturing myself, and it required a few GB of downloads. The good news is that the latest Windows 10 SDK does support GDI/CLI apps, so no crazy SDK hacking required, unlike back in the Windows RT days. Oddly enough the Taskforce 87 interpreter runs fine, but nothing else does.

I did a horrible job at hacking up SDL 1.2 to at least run (kind of, the audio doesn’t work, and it’s all WinDB *EDIT I got it fixed!!!) I got a few things up and running, including DOSBox and FrontVM. One thing that greatly helps is that i386 binaries ‘just work’. Honestly you wouldn’t even know you are running them when you are. Which made hunting down the ARM64 version of Chromium Edge kind of difficult to find. There really needs to be a more apparent way to tell them apart, if anything for battery efficiency.

As pictured, SQL Server 4.21a runs just fine, again you wouldn’t even notice. Same for Visual C++ 1.0 & FORTRAN PowerStation 1.0.

Again the audio in my crap SDL build doesn’t work, so DOSBox is silent, and without Direct X, the text mode is tiny. Oh also, there is no OpenGL in this version of Windows dev kit for some reason. Running ssystem is ungodly slow. Also the default optimizations seems to be Os, optimize for space, and on this ASUS I have to say /Ox is way way faster. DooM is quite playable on DOSBox when build with /Ox, unlike /Os.

For me, I spend most of my day to day in Office, and VMWare VDI, connecting to secure networks. So I’m just one step above a terminal. Which I guess is kind of sad, but this machine more than fills that roll for me. The 120GB of storage is tight. This isn’t a development machine persay, nor is it something to download tonnes of data to, it’s a lightweight machine where it’s strength is the built in 4G modem, and when running ARM software the longer battery life. To me the biggest drawback is that the keyboard isn’t backlit. Even though I touch type, I didn’t realize how much I’d grown used to it for casual use.

I guess it’s a hard toss up from this and a PINEBOOK Pro, I think most readers here would prefer the Pinebook, for all it’s openness, although I still like the idea of being able to copy over the Win32s version of Lemmings, and it just running. For me I kind of like this thing, although once I switch back to an x86_64 with more memory, better GPU and disk options, maybe this just feels like some kids toy.

Neko98 ARM!

I don’t know how I didn’t think of this, but I also ported Neko98! Although the STL is having an issue with the ‘control panel’ so Neko is on autopilot.

This app can’t run on your PC

As for the emulation, it is 32bit only, so expect to see this stupid message quite a bit. The neckbeard is a nice touch though.

Also built into the thing is a cell modem. I guess it’s really not a surprise as the 835 really is a cellphone SOC. I have a ‘wifi egg’ as they are called here, a WiFi hotspot with unlimited internet from CLS, which is on the old 4G network. I popped the SIM in, and it picked up the APN settings on it’s own and I was connected in under a minute. I have to say that it’s about time that SIM cards have this stuff programmed into them for a plug & play experience. And thankfully the ASUS is unlocked, although from what I understand these were sold in the USA bundled with some cell service plans.

For anyone with one of these rare machines that cares to play along you can find my built stuff on my ‘vpsland’ archive:

And the f2c/dungeon build along with the C/C++ compiler is in the aptly named dungeon-2.5.6-ARM(32bit) file.

As I previously mentioned I’m slowly but surely uploading all my stuff to

You may want to know that I just finished uploading apps for Windows NT RISC… Alpha AXP, MIPS and PowerPC. Happy downloading.
