The CPC+/GX4000 has a female 2x18 pin cart-edge connector for cartridges.

In the schematics, the pins are numbered A1..A18 and B1..B18. However, the text layer on the cartridge PCBs typically uses a different numbering: 1..36 (with even numbers on the solder side of the cartridge) (and with numbers ordered in opposite direction):

  • The SIN,CCLR,CLK4 pins are special signals for the ACID chip. Cartridges won't work without ACID.
  • Note: Arnold V specs say that "ROM CARTRIDGE: 2 pcs 2 x 9 way 2.5mm pitch sockets." This seems to be nonsense (or might refer to an internal connector on the mainboard). The external cartridge connector has 2x18 pins - not 2x2x9 pins.
