So my Counterforce has been pretty much rock solid for the past 4 years. Ground mods were done, some connectors replaced....basic sys 80 stuff. Well, tonight I go to turn it on, and it's mostly dead. All backbox lights are on, even the controlled ones, no lights on the playfield (although they do blink when first turned on), and weirdly, the credit display shows a little "c". This could be a glitch, or it could be trying to tell me something, not sure. Power supply voltages are good, and +5v is going to the MPU. Almost seems like the MPU is locked up or something, but I am at a loss. Anyone seen anything like this before?
New! Dark mode!
