Yamaha V50 EPROM sizes?
2011-04-06 by GB
I'm trying to burn some ROMs for the V50 from some
chips (files) I read many moons ago. I don't remember what the parts in the unit
are. There should be a Main A and a Main B EPROM that is possibly 1Mbit
... 128k x 8? 64k x 16? And a smaller Sub EPROM that I think is a 27256
type. Does anyone have this info?? Or maybe service notes or a
schematic?
Thanks,
