Never got around finishing this project.
Selling 3 sets (6 pcb's) of fluffy's PGM design.
Same price as Fluffy charged. 45 gbp ~53 euro.
I have an original NUC running a NAOMI system without GDROM.
Would like a nice plug n play ready multi for this cabinet. Either netdimm with a PI based on NAOMI, or something else with JVS, like a Taito TX2. Or whatever's out there...
