Working on some Tron PCBs. In the MCR FAQ:
>SW4 (the reset switch to the Z-80) isn't very sturdy either. Sometimes it'll latch "closed" and cause a constant reset state in the game. Test it with your multi-meter.
So I tested all my reset switches. 5 out of 15 were bad! I "exercised" them. I reflowed solder and still, 5 are bad. My problem is, how to replace them. If I understand the schematics (and I admit I can barely change a fuse), it looks like they are NO (normally open). Does anyone have a source for 4-pin NO switches that would fit the MCR footprint?
