The Yamaha Single Cartridge Adapter allows to use the specific Yamaha Expansion Bus Connector, as found on some MSX1 Victor and Yamaha computers on the back under a cover labelled "PEAP Slot", as a second cartridge slot:

It is actually a male edge connector. By default it is covered up to prevent dirt from entering the system, or accidental shorting of pins.


  • The Sakhr AX-100 has also this expansion bus, but it can't be used because it's occupied by the Arabic rom.
  • The MSX2 Yamaha YIS-805/128 and /256 also have an expansion bus, but these machines already have two MSX catridge slots, and the expansion bus is probably different, as it is meant for a digitizer.
