All — Made some good progress today. I built the console cable and verified that the serial console board was properly jumpered. I put in all of the boards and turned it on and I saw the following on the console: 173002 @ Yea! Looks like it works. I connected it to PDP11GUI and ran a memory test and it seems to be fine. Interestingly, the RUN light only blinks at startup and no other time. Not sure what that means, but it’s running. I have a couple of things to do: * I need to repair the side panels. I bought epoxy putty today and I’ll give that a try tomorrow. * I’d like to remove the flat black paint from the metal front panel. Any recommendations? It looks like regular latex paint on top of the painted metal panel. I have a 3M “safe” (non-VOC) paint stripper that I was going to try. * I have another SLU that I’d like to configure for use with the TU58 emulator. Any advice on this? Thanks!
