Trying to get to console on a Jensen
I have been given a Jensen (I believe aka DECpc AXP 150). I am told that the
machine worked when last used, but I am unable to get even to the console.
Here is what I have tried:
First I connected a VRT17 monitor and a keyboard (actually a PC one rather
than an LK411 as I did not have an LK411 at that time). Nothing appeared on
Then I switched to trying to get the console to work on a terminal, I have a
VT420 (set to 9600,N,8,1). I connected this to both of the 9-pin serial
ports (cycling the power each time). Nothing. I also tried connecting it to
the 25-pin printer port, still no luck. My breakout box does not show any
activity on the 9-pin serial ports.
There are 4 diagnostic lights on the back, they are all on and red.
I have been unable to find any documentation on the web.
Any suggestions what to do next?
