Digital KC 2048 KByte MemoryMapper

Minimum System Requirements

  • MSX2 computer, one free slot cartridge

Note: As all standard Memory Mapper, this cartridge is not supported by MSX1 computers except with Nextor or a MSX-DOS2 unbridled (like Sunrise CF interface). On MSX1 without Nextor, we need to manually initialize pages order of the mapper from basic before it can be used.
