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

It's actually the same adapter as the Yamaha UCN-01, NHK has also released the SFG-05 module as NSFG-05 and the FM Music Composer II (YRM-55 or YRM-501) as NYRM-55.

There is also the Sanyo version (KA-MAP-07), required to use the Kanji Word Processor KA-MAP-6 (¥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 of the adapters: ¥7,800
