I wrote a DOS-based program in Modula-2 back in 1991-2. It was never released. It had an integrated user interface written in assembly language, using direct video writes, supporting VGA and Hercules graphics modes (if you remember Hercules, you are an old-timer like me). The graphics was probably the best part of it, though, because the chess engine was junk, and like Dan, I was happy if it could solve mate in 4 or something like that. It tried to do some fancy dynamic eval with analysis of en prise pieces etc. - sort of like an eval function with integrated SEE. I'm ashamed to even show the code to this, although I still have the source.

Arasan was started from scratch some time later (1992?) and was C++, and more or less a conventional alpha-beta searcher with a hash table and null move, although I probably did lots of things wrong in my first implementation of this. Also it used Windows for UI (then a very new technology).
