Not sure what the issue is with Pin 13, GND, momentarily asserting *INT. Is that the "Module Pulled" mechanism?


My curiosity got the better of me and I looked inside my modded 71B and on the three modules inside, one of which I know for sure came from a CMT 32K front plugin and the other two look identical there is nothing connected to pin 11, and there is no obvious place to connect to LCIM, so the modules in the EPROM programmer must be different or modified since you say the switch is connected to pin 11. These modules also look the same as the ones that Mike posted the pictures of.

I meant pin 12 *int not 13 which is ground.


At the moment I can neither confirm nor deny that the P01 modules are custom. Examining the pics in Posts #3 and #4 of this thread, the modules certainly look identical from the top side.

When you say nothing is connected to pin 11, you verified this visually or with an ohmmeter?
