It's unfortunate that the Turbo Pascal (with inline X86 asm) source code of FT2 written by Vogue and Mr H hasn't been released after all these years. It's so seminal to so many people from that era.

If I were to guess, they found the quality of the code too embarrassing, years later - they were kind of kids when they wrote it. I did see that they (supposedly) shared the source with someone on Vogons for the purpose of minor updates/bugfixes.
