QuoteNo idea if this helps.Some. At least we know the cart is getting power (pin 38 == 5V), and that /CART is right (0V).
The fluctuations on the address lines probably mean they are changing (if you used a meter, those are average voltages)
It's the block of 5V in the middle that bothers me; Pins 15-23 (excluding pin 18, which is GND == 0V)
should be changing as well. Yet it appears they are stuck at 5V, which is a 1.
Looks like a dead card to me. Or possibly the data lines are shorted together somewhere...
