This is a cartridge port replicator by RACE Electronics, pretty much like the Tandy CoCo MultiPak, that allows up to 4 cartridges to be inserted.

Technical information

  • Writing to address $feff will select one of the 4 slots (0-3 - only bits 0 and 1 are used ; other bits are discarded).
  • Reading address $feff will select slot 2
