... my Logo from 1985 :) Sorry, just plain old BASIC, haven't learned Z80 at that point yet.
Changed the title / name though, hence updated for 2018 8)
It's on the DSK (virus scanned of course :P )
Originally, I called myself "P-C-S" - Polygon Cracking Service. Hence the polygons left and right. Never cracked anything besides ripping off the music in this BASIC program from the Amstrad Welcome Tape though ;D Funny what kind of stuff a juvenile teenage brain comes up with.
PS OK, back then I didn't know Lisp of course... I have added that now (instead of P-C-S).
Whoever comes up with an explanation of what ((lambda (x) `(Lambda ,x)) 'Mikel) does, gets the bonus price! :)
