- The first C64C that came out had still a full length board, ASSY 250466 that is considered the perfect full length board with only 2 x 64k x 4bit RAM chips, the MOS 6569R5 VIC-II chip and the enhanced SID chip (MOS 6581R4AR) with ‘Advanced Resonance’.
I found this board in a highly damaged C64C I got to get chips from but when I saw the assy I decided to fix it!
