MSX Slot Expander

MSX Slot Expander

SKU: Slot Expander

Slot Expander for MSX computers.

New Rev 3.7 board includes audio mixer with adjustable volume for each slot. Also accept external 5v PSU for extra power.



    Expands the regular MSX slot to four subslots, allowing to plug up to 4 cartridges simultaneously. You can now use your IDE, FDC and sound cartridges at the same time. 


    Attention! Cartridges that implement expanded slots by themselves (Carnivore2, SD512, etc) will not work properly when plugged on the expander.

    If the total power consumption of the plugged cartridges exeedes the total power output of your MSX you will need to use an external power supply for the expander.

    Some cartridge combinations might be incompatible; we cannot test every cartridge out there for ovious reasons. 


    • For MSX1, MSX2, MSX2+ and TurboR machines.
    • Individual ON/OFF switch for each sub-slot.
    • Audio mixer with adjustable volume for each slot.
    • BUSDIR support
    • External 5v DC input connector

    Package includes slot buffer cartridge, slot expander caddy and ribbon cable.
