Hi Eric, Yes, that looks the one we have, and yes it has the three pen holder. I found a user guide of the machine, but our left control panel area is different than that pictured in the user guide. I took some more picts of the pcb's in the machine. I will post them on our hack42.nl site

PDP-11/10 repair started

I have spent some time on the ill PDP-11/10 this weekend. I have this machine already a few years, but I recently got an empty H960 rack, which would be the perfect home for this PDP-11/10. When I picked up this 11/10, the story with it was "not good". "We put the boards in the backplane and

Some corrections to my post regarding the console LED behavior. Voltage levels on the CPU backplane are still good whne the 2 CPU boards are installed in the backplane, but the processor is not responsive to the switches on the console panel. The RUN LED is on, ADDRESS/DATA are all off. When
