Master controller for Nikkodo / BMB CD-i karaoke systems. It is similar to the Philips CDI 181 MultiMedia Controller (JNMS). The mainboards of these units were made by Kyocera. They all lack optical disc drives and require additional units (e.g. CDI 180 for JNMS and CDI-A1500 for BMB).
So far, three different hardware generations have been found, and there may be more. The hardware has evolved from being very similar to JNMS to something that hasn’t been seen in other CD-i players. To identify different mainboards/generations, I use the first character of the serial number:
- A unit – mainboard PDCDG4001D (this WIP Page)
- L unit – mainboard PDCDG4002B (upcoming WIP Page)
- V unit – mainboard PDCDG4003B (upcoming WIP Page)
