Apple ][

My Apple ][ (added to my collection in 2014)

  • 6502 CPU at 1Mhz
  • 48k RAM
  • Lower SN likely 1978/1979 case with mid 1980 motherboard, so it seems to be a mismatch
  • Dual voltage Astec power supply, also possibly a mismatch to the case
  • Early “Rainbow cable” Disk ][ drive
  • Hayes Micromodem II 300baud modem
  • Period correct (1977) B&W CCTV monitor

While this system is a mismatch, it’s an old mismatch, likely repaired back in the early 80s with a newer logic board.
