A weird EBay interlude on the way to Extending DOS.

I’ve always been fascinated with DOS Extenders, as they are such an ingenious method of breaking the rules of an environment by cheating the system. The first one I, like many others I imagine was using was DOSX that is the heart of Windows 3.0 on the 286. An incredibly tiny program but it let Windows run in protected mode, unlocking the potential of the machine. Great!

But as an aspiring programmer things were a quite a bit different. While QuickC for Windows did give you Microsoft C 5 hosted inside of Windows, effectively making the $99 for Windows and $99 for QuickC for Windows the cheapest DOS Extender dev kit of the time, it was of course limited to the 286. The 386 stuff although being the genesis of the DOS Extender was far more expensive.

But then with the advent of EMX for OS/2 and DJGPP for MS-DOS, both of them included DOS Extenders, and even better they were gratis! But of course they were GCC focused, and me being a kid saw the incredible 1MB++ size of CC1.EXE was thinking it’s insanely bloated, and of course slow. I don’t think many people were using 80386sx-16’s but I was.

Then there was this incredible offer from Watcom, who’d just become an internet (yes on usenet!) darling for being the compiler used to port DooM from NeXT to MS-DOS and it was available to students for a whopping $99. Neat!

Watcom C/C++ 10.0 retail packaging

Being in collage this was great. Another big plus of Watcom is that it was able to host on MS-DOS, Windows NT, and OS/2. And target far more!

So much included in the box!

Back then there was such incredible platform diversity in the PC space. Servers could be NetWare, Unix, OS/2 and that new fangled and often delayed Windows NT. Watcom was uniquely positioned to support so many of them, all from the same compiler set.

And of course most famously was DOS/4GW included in the box!

Despite having this, I’d always wanted Phar Lap TNT, as it brought insane features of Windows NT to MS-DOS, like DLL’s, and threads! But it was expensive, and I couldn’t justify it.

And this is where the story gets weird as I was also looking for their 286 product, and I found a copy on Ebay, and even better I easily won!

I can’t get a higher resolution image as the auction has expired out. But take note of the thumbnail.

PBI

And this happened. I was all happy expecting it to arrive when out of the blue the order was cancelled and refunded. I contacted the seller as I was totally wanting to get this, and to see if there had been some screwup in shipping, and they had told me that they didn’t know either has they had been refunded the sale price+shipping. So there we both were, me without my 286 Extender, and the seller with no disks to try to sell back again. And then this happened:

Phar Lap 286 magically reappears!

The disks showed up again for sale. We were both dumbfounded, how did this happen? Somehow someone intercepted the sale, and refunded us both, and then is trying to sell it on their own? Interestingly they won’t ship it to me, almost as if they are trying to block me from it.

Sketchy as hell as they say they are reselling from 3rd parties. Is there some kind of hustle going on where someone at a combined overseas shipping centre grabs random items, they can issue a refund for both parties so we don’t care, and then use a proxy sales site to sell them again?

Interestingly they know the disks read fine, as I know that too as I’d asked the seller to image them for me incase anything happened in shipping. I just never imagined it’d have been intercepted and resold. Maybe it’s common place, but I’ve been using Ebay since 1998 or so and well it’s the first time I’d ever seen something like this. Naturally bringing it up with Ebay is a total waste of time.

I’ll have to continue this with a deeper look into Phar Lap 286|DOS-Extender 2.5 as this is already far too much of a diversion from where I was going. But I thought I should point out this thing so buyer beware about the current listing.

**EDIT

Well seems I had the opposite effect I was looking for:

SOLD!

    • Yep that’s it all right! So interesting that they picked a 4 disk set. I guess they do random grabs, but what a strange business model. Someone has to refund me & the seller, and their sale price for the intercepted package is only $1 more than the original sales price.

      combining shipping doing containers is nothing new or exciting, it’s basically how mail works. However reselling back on the same platform things that are intercepted is just plain weird.

      It feels like there is something much more sinister going on.

  1. I’ve been ignoring Phar Lap as part of Visual C++ 1.x installs for decades.

    Looking now, it is incredibly heavily patterned on 16-bit OS/2. Visual C++ outputs an NE binary that’s marked for Windows 3.1, but the Phar Lap runtime will happily run OS/2 binaries, and the functions it’s using are the same doscalls ones from 16 bit OS/2.

    I tried building a binary with Visual C++ and taking it to OS/2, but it looks like the startup code includes a PHAPI.DLL dependency. It should still be possible to make it work with more minimal startup code though. It is possible to take Hello World from C 5.1 targeting OS/2 and run that Phar Lap, so the PHAPI startup code isn’t necessary to function.

    Phar Lap (even the Lite version) uses DLLs extensively, since it’s just implementing an NE loader. “Real” OS/2 binaries (the C 5.1 compiler itself) won’t run because of missing DLLs, but taking a 16 bit version of NLS.DLL, and it executes. I haven’t tried to build a “real” toolchain out of this yet.

    It seems though like this should be enough to use the OS/2 toolchain for Word 1.1 when compiling on DOS to eliminate those annoying out of memory errors …

    Although, the other thing I hit messing with this is I was using NT 3.51 for these experiments, but it can run OS/2 binaries itself without help from Phar Lap, so maybe I should just compile Word on NT.

    Btw, I’m curious if TNT is really bringing NT (PE) executables to DOS rather than the NE ones supported by Phar Lap 286. The DOSXNT bound DOS/PE executables are still somewhat useful, since they’ll run on the latest 64 bit Windows 10 but also back to DOS.

    • Windows NT from the beginning until NT 4.0 have the OS/2 subsystem and could run OS/2 16 bit binaries like you comment, this was so their customers could run Microsoft SQL Server for OS/2 and other server software that they sold.
      Out of the box it only run console applications, but if you was an important customer and had the need they sold you “Microsoft OS/2 Presentation Manager for NT” so you could run Presentation Manager applications.

      • I had bought a couple of “Microsoft Select” CD-ROM’s for ‘partner use’ and I was so excited to have it in my hands as burried in one full of service packs for office was the fabled Presentation Manager for NT. And it’s exactly what it sounds like. Sadly I really don’t have any 16bit PM applications, and the Microsoft ones (Word 1/ Excel 2) are rebound Windows ones, and it really confuses NT.

        • What a find!
          For many years it was just a rumor for me, a unicorn, like the Microsoft OS/2 32-bit SDK (that we could only hope that someday will appear).
          Even when I had running OS/2 2.0 and Warp in my computer back in the day, I don’t remember running 16-bit programs, it was the software that came with the system, DOS programs, Windows 3.x programs and shareware and other stuff that you found int the Internet which was compiled with EMX so was UNIX ported software not tailored specifically for OS/2, there was really a lack of programs.
          That said, one of my projects is compile the sample code y old compilers and other sources for OS/2 and test it in OS/2, Windows NT, 2ine and who knows, probably make some new program…

          • I’ve uploaded it all over the place, it’s kind of easy to find now. It’s weird now that it’s been out for years, you’ll have more trouble finding Presentation Manager applications!

            You’ve come to the right place for messing around for dev tools, as close as we’ll get to that fabled Microsoft OS/2 2.00 Pre-Release 2 stuff is 6.123 and the OS/2 2.00 Pre-Release 2 SDK.

        • Very nice find. If you want to snag a full-blown 16-bit PM app that you can use to try to put PM-NT through its paces, I’d look no further than the DeScribe 3.0 beta that WinWorldPC is hosting. 4.0 was the first 32-bit build of DeScribe for OS/2, and the beta copy on WWPC has separate installers and (unbound) executables for both Win16 and OS/2 1.x!

          • I just installed it. Sadly it just hangs trying to do anything, but it did install! Oddly enough I tried Excel 2.2 and that works fine. Go figure!

  2. I have a disk with a LITE version of Phar Lap that was originally supplied with Borland C++ 3.1. Then there was also the Borland Power Pack that came with C++ 4.5, which had 16 and 32-bit extenders.
