MSX Cartridge slot

MSX Cartridge Slot

The MSX cartridge slot is the standard expansion port, as defined in the MSX standard definition. It can be used for program cartridges, such as games, or for hardware expansion.

Most MSX systems have two primary slots available for expansion, although some have just one, and may have a proprietary expansion slot.

A primary expansion slot can be split into 4 sub-slots using a Slot Expander.

Lists of machines

NOTE!
These lists have been created to indicate which computers have more or less than 2 standard MSX cartridge slots.
They don't include video titlers as these machines are very difficult to use as normal MSX computers.

Machines with only 1 MSX cartridge slot

Without expansion bus (or Yamaha module) slot

The following machines with only 1 MSX cartridge slot don't have an expansion bus (or a Yamaha module slot), so the only easy solution is to insert a slot expander in the unique MSX cartridge slot:

With expansion bus (or Yamaha module) slot

Many MSX1 machines and a few MSX2 machines have only 1 MSX cartridge slot, but most of them have a proprietary expansion bus which can be used as second cartridge slot. Besides, a module slot can be present when it's a computer manufactured by Yamaha.
