Hi all, I'm pretty new to PDP-11s. I recently got a PDP-11/73, M8192 CPU, two M8067 RAM, M7195 (2 async SLU card with boot ROMs and an extra 128K of RAM), plus a few other cards which I've removed to try and figure out what is going on.
While playing in ODT, the console completely stopped responding. I hooked up pin 1 to a scope and I can see the UART clock, divide by time per division and 16 and I get something close to 9600. The M8192 CPU has four diagnostic lights, as does the SLU. The CPU shows 1000, which I believe is fine, and means it's in ODT. The SLU card has 1111. I've had a Google and I believe this means it can't communicate with the CPU. I've cleaned the contacts with 99%+ isoproyl, but no luck unfortunately. Does anyone have any ideas? It was working and then it wasn't :( Thanks, Aaron.
