The C64 basically consists of the following units:

  • 6510 8 bit microprocessor
  • 6567/6569 VIC-II graphics chip
  • 6581 SID sound chip
  • Two 6526 CIA I/O chips
  • 64KB DRAM (64K*8 bit) main memory
  • 0.5KB SRAM (1K*4 bit) Color RAM
  • 16KB ROM (16K*8 bit) for operating system and BASIC interpreter
  • 4KB ROM (4K*8 bit) character generator

Most chips are manufactured in NMOS technology.
