[rescue] New to me PDP-11/23+

[Steve Hatle]

I recently came into an 11/23+ machine. It has a KDJ11-B CPU board, a 
MSV11-Q memory board, a SCSI board that was driving a SCSI Zip drive for 
boot media, and two cards that were used to control a laser cutter.

First issue is that there is no "bulkhead" to bring out the console 
connection, so I need to figure out how to get a terminal connected to 
the J1 SLU connector. This is 9 pins, but I can't seem to find 
definitive info on what the pin assignments are here, and exactly which 
pin is #1. Once I know these things, I'm sure I can make a cable with 
TX/RX/GND to get a console going. Anyone have pointers? I found a set of 
schematics but what I think is showing J1 doesn't make sense to me.

Then, I need to figure out how to get software set up to run the thing. 
I didn't receive any of the Zip media previously used, or any 
documentation for the machine. I'm guessing I can use SIMH and perhaps 
build a bootable Zip or other SCSI drive, but that will need to wait 
until I can at least talk to the thing. Lacking any other serial ports, 
I don't think I'll be able to take advantage fo the TU58 emulator or 
other solutions.

Looking forward to getting this guy up and running!
