The Yamaha UCN-01 Unit Connector is an adapter allowing to insert a SFG Yamaha module with 60 pin in a standard 50 pin MSX cartridge slot.

There are 2 other similar adaptors for the same price:

  • the NHK version (NHK NUCN-01)
  • the Sanyo version (KA-MAP-07), required to use the Kanji Word Processor KA-MAP-06 (¥49,800 yen) on a standard MSX slot

These adapters are useful to transform any MSX computer into a SFG musical computer. They can also be used with other Yamaha modules such as RAM expansions or Kanji characters.

Official price: ¥7,800
