The 64c was a cost-reduced version of the 64 where many chips were integrated
into larger ones, they also re-vamped the SID chip which takes a different
voltage then the original SID and has 'fixes' whaich makes some earlier
programs sound worse (there was a 'click' you get when adjusting the volume
control, and it was used for digitized sounds, the new sid fixed this click,
now no digitized sounds in some progs. I dunno the 64c SID number but I think
that (8580) may be it... :/
I think the 6582 was in the 128 or 128D...
