PDP-11/44 problem - RUN stays on

Sorry, one follow-up on my own message. I forgot to mention that I searched the classiccmp archive, but was not successful. I remember a thread about a voltage comparator issue on the CIM (M7090), but could not find it. Perhaps that was on usenet ... I must take a look at the M7090 electrical diagram! - Henk.
