I have a Data East Ver. 2 board and I suspect a special solenoid transistor might be bad. How do I go about testing transistors with a basic Craftsman DMM? What setting should it be on? And what values should I get so I know whether its bad or not.
I tested the transistors following a pin repair sites instructions. But it didn't say what the values should be. All of the values were the same (or similar) but one was totally different. I just don't know whats normal.
Some of the transistors have obviously been replaced. And it looks like quite a hack job. Is there anywhere to get a Data East Ver. 2 or 3 board without paying an arm and a leg?
