I want to mark this date.
Just created, compiled and run my very first 6502 asm code on 8-bit Atari and Apple II (on emulators that is).
Now I only need to repeat the same for Acorn Electron.
And then... I'm going to rewrite my old Turbo Wieszcz++ for C-64 (from 1993) with new data and code
and (re)release it for: C64, Atari, Acorn and Apple II at the same time :)
