MSX Club Gouda 5.0 SlotExpander
This page was last modified 14:54, 13 January 2022 by Mars2000you. Based on work by Gdx and Rderooy and others.



The slotexpander expands your slot into 4 subslots. These are numbered from 1 to 4. The one which is closest to the switches (this is the front) is number 4, the one on the other side is 1. The ones between are 2 and 3.

Although the subslots are numbered from 1 to 4 on the expander, the computer really sees them as subslots 0 to 3.

Every slot can be turned off. This done by the switches in front. To the right they are on, to the left off. The I/O ports are still working in the off position.

Support for an external power supply has been removed on this latest version from Gouda unfortunately.

Known issues

  • FM “stereo” PAK: the internal software is not working, unless a RAM cartridge is inserted in the expander.
  • Metal Gear 2 - Solid Snake normally works from primary slot, but also works fine when inserted in slot 4 (front) of the slotexpander and no RAM cartridge is inserted into the slotexpander (or the RAM cartridge is switched off).
  • Snatcher Sound Cartridge doesn't work in this slotexpander, probably because of the flatcable length (weaker signal). Use in primary slots instead or confirmed: Snatcher Sound Cartridge does work in Carchano slotexpander (without flatcable).
