I have a DLV11-J...I THINK one of those can be used as
a TU58...but I
don't have a bootstrap module (yet) so I'm stuck with ODT.
I'm running at 4800 baud and I can go no higher or lower due to the lack
of wirewrap tools.
You can solder wires on the bottom (track side) of the PCB (to avoid
messing up the wire wrap pins) i you don't have a wrapping tool.
I had ot loading executables earlier...but then it stopped working. I'll
let it sit overnight and pick it back up tomorrow.
When one of my PDP11s (admittedly rather older, and Unibu) behaved in
strange ways like this, I foudn (after a lot ot troubleshooting) that the
PSU was fialing ad that the 5V line was sittign at 4.2V. It is well worth
checkign all the power lines at the backplane just in case.
