Electricians do not do this sort of work. They primarily pull cable
and run what amounts to plumbing and lots of physical construction.
What you're talking about is engineering.
It would likely be easier to repair the existing power supplies. Are
schematics around?

Or the occasional 3.3. You can also get hacky and drop the voltage on the rails with the right circuit.

Thanks guys, might try this out on one of my MicroVAX 3400s at some point,
I've run out ethernet transceivers so I'll wire it into a VAXstation that
is
HECnet connected.
Would this work?

The VAXstation will need to configured as a router, but that is very easy to
do.

That usually happens when NML is not running either because was not started or
because has stopped. Given that you are using a DECnet-enabled monitor, your
SYSTAT should show something like this:
Well, r NML says "not an EXE file". This could be related.

If NML is e.g. in TO state (Terminal Output) that means that it encoutered
some error and is waiting for someone to read it and do something...
NML gets automatically started by ORION, which in turn gets started by QUASAR,
which must be listed in SYS:SYSJOB.INI:
All that is being started...but I think NML.EXE is broken. ;)
