Description

The NHK Gakuen NSFG-05 called FM Sound Synthesizer Unit II is the same Yamaha SFG module as the SFG-05, it was manufactured by Yamaha and released for new students of the NHK schools who registered up for the Music Course (音楽コース).

This course is one of three that were available. It includes a FM Music Composer II (NYRM-55) and a "ROM & RAM" cartridge containing NHK School's Computer Lessons Preparatory courses (NHK学園パソコン講座入門コース), exercises to learn the Music on computer.

The RAM is in fact a 8kB SRAM, probably used to store the student's answers. The white parts on the cartridge sticker were used to write the student number and name. See Gallery on the NHK Gakuen Modem page for pictures of the "ROM & RAM" cartridges.

The NSFG-05 is build around a YM2164 (OPP) sound chip and YM2148 MIDI UART. Launch price: ¥29,800

This module has a 32kB ROM (MBIOS 2.0) which supports MIDI input, so it allows the internal FM synth to be played by any external MIDI keyboard.

It has 2 MIDI connectors (MIDI-IN and MIDI-OUT), 2 audio stereo connectors (L and R) and a music keyboard connector.

NHK Gakuen also released the UCN-01 UNit Connector as NUCN-01 and the FM Music Composer II (YRM-55 or YRM-501) as NYRM-55.
