Notable ICs on the Mac 128K logic board: Motorola MC68000G8 Microprocessor
  • Notable ICs on the Mac 128K logic board:

  • Motorola MC68000G8 Microprocessor

  • Fairchild Semiconductor 74LS393 Video Counter

  • Micron 4264 64 kb RAM (64 kb x 16 chips = 1024 kb, or 128 KB)

  • The namesake for the 128K was this non-upgradable array of RAM. Anticipating that customers would want more power, Apple engineers secretly designed the logic board to facilitate manufacturing a 512 KB version, which was released only nine months later.

  • Simtek C19728 and C19729 32 KB ROM (32 KB x 2 ICs = 64 KB)

  • Simtek 344-0041-A "Integrated Woz Machine" Disk Controller

  • Zilog Z8530PS Serial Communications Controller
