Fond memories.
If I remember correctly I had a commodore Vic 20 and it's bigger brother Commodore 64.
Nice machines. Wonder what happened to commodore, never really followed up. The amiga range was quite strong though.
Ahhh the Z80, if I remember right, it was this little processor were I first met assembler programming. You would do your program on paper, get the equivalent hex codes and using some kit program your cpu, then hope for the best.
Wow, that was so cool, now we have these major complex dev tools. Even more fun.
