• Big mainboard, separate soldering points for old and new Gate Array (with changed pin-outs). Fragile plastic wires going to keyboard.

CPC464 version 3

• Board: PT NO Z70375
• Board: PT NO Z70374, MC0044A
• Medium sized mainboard. Seems to be same as previous version, except that components are arranged more tightly.

CPC464 version 4 (cost-down)

• Board: PT NO Z80329, Copyright 1988
• Tiny mainboard. Uses 100pin SMD Gate Array (combines the old Gate Array, CRTC, and some FDC/DRAM/RESET logic in one chip).
