same here, but in 6502 machine code on my homebuild MicroTan 65 for me. A whole 1K. Half of which was the display memory (32 * 16), the rest being Zero page (page 0, see) with something like $40 bytes used by the 1Kb of monitor (BIOS for modern readers :) and then page 1 being the stack. And one had to fit ones code inbetween. much fun.

And you try to tell that to the youth of today, etc etc etc

You have a C=64 on your watch? Wow...
