Hey all-
I've finally gotten around to putting together a MCR test fixture. I threw this together because I have a small stash of MCR boards I'd like to get running! Here is what I'm working on now:
"Super CPU" with Tron ROMS- This is the middle PCB in a MCR stack. I have it connected to a known working Video Generator PCB. I can't get this to boot! Here is more details:
Known good-
Power supply/voltages- Running a switching power supply with a MCR PS adaptor
Video Generator PCB
Ribbon Cables
All socketed IC's verifed and sockets look good
Any ideas on what I should be looking at next? I have a logic probe, but not sure where I should be looking.
Thanks-
Mark
