Back to the revision 2 Aiwa mainboard, silkscreened 02-01. At this point it is the only one of my two CSD-GM1 mainboards passing power through to the Game Unit section, which makes it useful for comparing both Game Units.

Came across a few problems on this one, never fear there are always more parts on order. One day these units will shine with perfection. Well maybe not exactly perfection, but they’ll function alright!
