Does anyone know where i can source a new U9 CPU Chip for the M-200?
Don't worry about that just yet, you stil have the old sh&*t sockets on the board, first port of call is to replace them.
That add on board is to run a 6116 instead of a 5101
I'm powering up the board on the bench with a modified PC PSU, so connectors aren't the issue just yet, however that said, it's on my list of things to change.
