KDJ-11 PDP11/73 digrams needed

[Jim Beacon]

Hi,

while repairing some 11/73's at work yesterday, I ended up with two gaulty
KDJ11 processor cards, one has not TX data from the SLU, and the other
doesn't talk to the rear panel 7-segment displays.

The company policy is to replace the CPU, and scrap the u/s unit. I suspect
the faults are fairly trivial, and am looking for a circuit diagram of the
KDJ11 so that I can have a go at repairing them. Can anyone point me to an
online source?

Thanks

Jim.
