The RUN light thing now makes sense. Thanks for clarifying it. I’m still reading the 11/03 manual.
The SLU is from Heathkit and it’s a single port SLU probably equivalent to the DLV11/M7940. The primary card is set for 176500 and a vector of 300. I have a second card that I wanted to use to connect to a TU58 emulator but maybe there’s a better way to accomplish this.
