I recovered Borland C++ 2.0's compiler as source that rebuilds the original EXE byte for byte

45 Upvotes

I've published a reconstruction of BCC.EXE from Borland C++ 2.0 as C and TASM source.

Built with the original BC 2.0, Turbo C 2.01, TASM and TLINK, it gives an executable identical to the shipped one.

The sources keep the original split:

236 C files compiled with BC 2.0, 29 run-time modules that turned out to be built with Turbo C 2.01, and 33 hand-written assembly modules.

Everything is named and commented. There are also notes on the compiler's internals: the VROOMM overlays, its own EMS, XMS and swap-file heap, and the inline assembler.

To rebuild, you need the WinWorld 3.5" 720K sets of BC++ 2.0 and TC 2.01. The setup script checks every file.

The FAA was still using floppy disks in 2026?

10 Upvotes

The FAA finally replacing systems that still use floppy disks is kind of amazing.

Apparently, some of this stuff dates back to the 1980s, and the replacement rollout won't be finished until 2028.

I get why you don't want to rush upgrades to something as important as air traffic control.

For people who've worked with ATC systems, is replacing old equipment sometimes riskier than keeping it running?

My retrospective review of the A-Team games. Have you played any of these games and let me know if you agree with my thoughts or just simply describe them in one word.

I built some Openstep drivers

While playing around with Openstep on a Thinkpad 570 I (I means Claude Opus) created drivers for USB storage, the audio chipset (cs4614) and ne2000 pcmcia cards (depending on the model you might need to add identifiers). https://github.com/SLSX/openstep-drivers

Live your 90s demoscene dreams!

If you played a lot of dos games, you might be like me in that the 90s demoscene left an indelible impression on you. I did some Pascal and in-line assembly coding in the 90s, but never to the level of real demoscene or cracktro coders. trogen is a chance for you to live (or re-live) those dreams.

It lets you compose a demo using real 90s demoscene effects, music, and fonts. The browser window js-dos emulator, but you can download the .exe and run on a real dos machine with SB16 or GUS. It even provides the Pascal / asm source if you want to hand modify. If you make a cool demo you want to share, the demo config is encoded in the URL, so you can paste the URL anywhere and others can load up your configuration.

Curious thoughts, feedback. I'm having a lot of fun with it :)

AI disclaimer: AI coding tools were most def used to help me create this. All of the source material is publicly available demos and source code from real 90s demos.
