I learned to program on Commodore 8-bit computers, starting with the VIC-20 and then graduating to a C-128 (I skipped the 64, but that's OK since the 128 had one inside. :))

I still mess around with this stuff, mostly in emulation, and anything I think might be of interest I'll stick here.

evalhex_vic	a VIC-20 port of the routine from Programming the Commodore 64 that teaches BASIC to recognize hex numbers like $900F. Actually, it's a port of the improved version created by Robin of 8-bit Show and Tell and featured in this video.
