This C64 computer is Serial #19 and contains a Revision 6 motherboard built
just after Commodore debuted the 64 at the January 1982 Winter Consumer
Electronics Show in Las Vegas. The computer is in working condition and features
ceramic prototype chips developed specifically for the 64 by Commodore's MOS
Technology semiconductor division, including the 6581 Sound Interface Device
(SID), 6567 Video Interface Chip (VIC II), and 6526 Complex Interface Adaptor
(CIA).
