ReBirth RB-338 v.2.0

I’m not a big sequencer as I’m just terrible when it comes to music. But apparently on Wikipedia Propellerhead had set the download free, although download links now are inoperable.

After a lot of googling around I found it split up on one of those annoying download sites. So I spent the night waiting for stupid timers, training an AI to sport automobiles & intersections (lol redlight camera training), and as a reward I got the download.

ReBirth on Qemu under Windows 95

I installed it on the floppy version of Windows 95 on Qemu where it needed IE 5.01, Direct X, Winsock 2 & Windows 95 SP1 updates (among others…) and yes it works!

Included in the downloads is some assists so you can run it on Windows 10 x64 if you are so inclined.

Also there is some MacOS X images, although I haven’t tested them. I need to drag my G5 into my office to try it, but it’s getting late, and I want to go home.

I put the download up over on You can download it here:

Early MSDN CD’s on

I ran across this, and thought it was cool. These CD’s are getting harder and harder to find, and unless you want the old physical disks, getting ISO images is, of course the next best thing.

Granted these disks replaced the much older Microsoft Programmer’s Library. The new CD’s use a Windows based search & interface program removing the clunky old MS-DOS program that made it feel like trying to view the world through a straw. (Although the up side of the MS-DOS version is that you could easily dump the video RAM and save the contents to plain text).

And in this brave new post Windows 3.0 centric world of Microsoft just about everything regarding OS/2 was dumped, and the seeding of Win32 via Windows NT had started.

Naturally after winning this war, Microsoft withdrew many low end products and just couldn’t compete with the tidalwave that was GNU/Linux.

At any rate for the curious kids down the road that want to see what all the fuss was with Win16, and how Windows 3.0 had changed the landscape removing the force of IBM it’s worth a look.

Adding DOSBox’s MPU401 to Qemu 0.90

I thought this may be something cool, if not kind of pointless. Anyways the MPU401 UART can be run like a traditional serial port with an IRQ, in intelligent mode, or just as a ‘dumb’ device you can just bit bang to talk to MIDI devices. So while playing with DOSBox I thought it’d be fun to take it’s emulation and plug it into Qemu.

And this is the end result.

It’s far from perfect, when it works it does tend to work well, although it fails to work with things like Return to Zork, but it does work with DMX’s sound code in DooM and the MPU401 driver for Windows 3.1

While doing this I was originally struggling with mapping the IO ports. Qemu has some functions to map in the memory model to assign a function that will trap read/write space. In this case base is 0x330 the base of the MPU401 device.

register_ioport_write(base, 8, 1, mpu401_ioport_write, s);     register_ioport_read(base, 8, 1, mpu401_ioport_read, s);

I was thinking that the port 0x331 needed to be mapped in the same way, but it turns out after looking through more of the source, it’s actually a word aligned access. So in that case you can use a switch to see which port is actually being accessed.

static uint32_t mpu401_ioport_read(void *opaque, uint32_t addr) {
     case 0:
      return(MPU401_ReadData(addr,0)); break;
     case 1:
      return(MPU401_ReadStatus(addr,0)); break;
      return(0xff); break;

Pretty simple, right?

And from there it’s a matter of mapping the DOSBox MPU code, along with the Windows interface code. Since I’m not using intelligent or IRQ mode, I just amputated the code where applicable.

If anyone wants to look at what I did to merge into anything else (and probably do a better job!) it’s on sourceforge as mpu401.c.

Otherwise the binary is available on sourceforge:

VC6 Ultimate updates

I’ve been trading emails with various people from the project after I had made my post, and helping them integrate more of Visual Studio 2003 into the project and working through a few issues to bring far better compatibility to VS 2003.

And the best part is being able to build projects in parallel!

10.2 seconds in parallel!

I haven’t ordered new processors, so the 2.1Ghz parts are… lacking. However being able to use all available cores makes building DOSBox pretty fast.

Restricting the build to a single process takes 1:13 while the full parallel build on this machine takes a mere 10 seconds!

So absolutely check out VC6Ultimate!

Visual Studio .net Enterprise Architect

I uh, also saw this on, which may help people looking for this stuff from the future as old tools get harder and harder to find. Especially bigger editions like the Enterprise Architect version.

So I was building a Windows 2019 server

As I got a ‘totally legit’ serial code in my box of cereal.

After the install I thought it’d be fun to install the Linux Subsystem.

While following the powershell instructions here, I thought the list of quick links of distros to download was interesting:

That’s right ARM Linux userland! I still have high hopes for Windows on ARM (I have 2 Windows RT devices now!!) although I’m not holding my breath.

Maybe there will be some ARM boards that are suitable for the desktop that aren’t over 1k USD.. That’d be nice.

Interesting trivia is that the Linux Subsystem started it’s life on ARM as a way to run Android binaries on Windows Phone. And true to everything Microsoft does, it got to the point where it could start to run things (albeit poorly) and was summarily killed. Although it’s found life despite the original false start as a general ‘text mode’ subsystem for Windows.

However running Linux binaries on Windows currently just shows that NTOS isn’t as efficient as the Linux kernel when it comes to emulating the Linux ABI. Although this was the original ‘dream’ of the microkernel, and a POSIX subsystem for NT was always part of the original design, although it really was more of a checkbox for GSA contracts, and outside of being able to use pax & vi it really was handicapped by not having BSD extensions, and especially by not having any access to the TCP/IP stack.

VC6 Ultimate

I saw this the other day, VC6 Ultimate. It’s an interesting ‘update’ on the old Visual C++ 6.0 product with an improved UI, along with updated compiler toolchain taken from later versions of Visual C++. Naturally something like this is 1000000% unofficial.

Features include:

  • Portable and compatible with Win7 / Win10
    bye bye regedit, hello .hjson setting file !
    also meaning it should not mess with your current install
  • More compatible compiler
    multicore version of VC7.1 compiler (It’s fast)
    you can compile with other compilers (64bit), but not debug yet
  • Real-time highlighting and diagnostics
    based on libclang 6.0 and compatible with VisualAssistX
  • Real multicursor editing
    search, sort, number, evaluate, etc. while in multicursor mode
  • Improved UX and UI
    32bit icons, dark skin, lot of visual hints
    multi-monitor friendly
    revamped dialogs (project settings, threads, breakpoints, …)
    searchable command palette
  • It’s free (as in free beer)
    ever had to pay for a birthday present ? 😉
  • Every change has a toggle
    only take what you like, but we can not check each combination
  • It’s an internal spare time project
    don’t expect everything to work in every setup, but feel free to reach out

Included in the bundle is the following compilers:

  • clang version 3.8.0 (branches/release_38)
    Target: i686-pc-windows-msvc
  • Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.6030 for 80×86
    Copyright (C) Microsoft Corporation 1984-2002. All rights reserved.
  • Microsoft (R) C/C++ Optimizing Compiler Version 14.00.40310.41 for AMD64
    Copyright (C) Microsoft Corporation. All rights reserved.

It’s an interesting project, although I tried to re-build some Visual C++ 2003 projects and it bombed out. Maybe it’s just more geared towards VC 6 as indicated.

MSDN from October 1994

I picked this 20 disc set recently and ugh the cringe is just… insane.  And yes, that is Bill Nye


STUDS from Microsoft .
(Video in MPEG-1/Audio MPEG-2 care of JSMpeg).

I had this ages ago, although I couldn't remember if the NT 3.5 SDK/DDK had shown up at this point, but it's only the Japanese version in this set.  Since I'm having such a PITA in tracking down a 3.5 set, and I'm not sitting on this, I may as well archive it.

Yes, I had to rip 20 of these!

So you too can find the early Video for Windows, and all kinds of other things from the mid '90's on

Or Wallpapers like this 'puppy' from the Japanese version of Windows 3.1

Re-enabling WinHelp on Windows 10

There was a shift years ago from the old help system that has it’s roots going back to Windows 3.0, and was certainly one of the killer features of Windows 3.0, the hyperlinked and searchable help files.  They were a form of compiled RTF files, and could also embed image resources, and later audio & video with the evolution of Windows.  This allowed for a platform for early multimedia encylopedias and other refrence books of sorts.

Starting with Windows Vista, however the WinHelp engine was being retired out for a CHM or compiled HTML help engine.  And for a whlie there optional updates and later downloads to re-enable WinHelp.  However starting with Windows 10 the downloads no longer work.

All is not lost however, if you copy any of the 32bit WinHelp programs from NT 3.1 onward it will still function on Windows 10.  And thanks to this great post on TenForums, you can re-enable the hook so that Windows 10 will integrate again with WinHelp.

@echo off
set crtpth=%CD%
takeown /f "%windir%\winhlp32.exe" >nul
icacls "%windir%\winhlp32.exe" /grant *S-1-5-32-544:F >nul
copy /y "%crtpth%\winhlp32.exe" %windir%
icacls "%windir%\winhlp32.exe" /setowner "NT Service\TrustedInstaller" >nul
echo Done.
echo Press any key to Exit
pause >nul

WinHelp from Windows NT 3.1 refresh on Windows 10

And there we go, now I can load obsolete refrence docs from great old programs like Visual C++ 1.10 for Windows NT!

Naturally Microsoft removed all this stuff as it was a security risk, in that they apparently never revamped or updated it, so yeah it may be another infection vector.

Microsoft Fortran PowerStation for NT 1.00

So I came across this recently, and unlike the previous version I had for Windows 3.1, This version is for Windows NT.  And unlike the Windows 3.1 version this version does actually run on the shipping version of Windows NT 3.1, and thus will work all the though including Windows 10 on x64.  The setup program unfortunately doesn’t complete leaving it ‘unlicensed’ however it’ll still run.

The diskettes for the Windows 3.1 version I have are dated 11-23-93, but once installed the compiler is actually from February of 1993, with the Windows NT version being dated October of 1993.

So the nice thing with the Windows NT version is that you don’t have to mess with the compiler, and linker, it’ll just run.  And just like Visual C++ 1.0 / 1.10 for NT the linker doing a release build will always result in an exe being at least 2 megabytes in size.

I know that this is pretty much useless for 99.9999% of people.  Yes it’s ancient Fortran.  Yes Fortran PowerStation 4.0 is far more comprehensive.  Yes after it was sold to Compaq as part of some deal over the collapse of Dec & Windows NT, then sold out to Intel.  And GFortran is free.

But here we go.

32bit Fortran from 1993 in 2018!
