I also think it is in the spirit of the computer - using what is available
to fix a problem at hand. I think the arduino was overkill when an attiny
(smaller, easier to hide) would probably serve just as well.
If you have the ttl logic bits lying around and know how to use them, fine.
Still would probably need debugging.

have no problems in using newer technology in older machines. we have a
alix sbc build into our tek 4002a for demonstrational purpouses, all done
without damaging or altering the original machine.

time on the system. The power supplies are now
within spec.
Capacitors reforming naturally?
Warren made an Arduino based programmable baud rate generator that works
for both serial ports. After some debugging, it
works nicely.
I am sorry, but I find that obscene!. To use more components than the
rest of the machine
(probably) just for the baud rate clock is ridiculous. IMHO if you are
going to modify a
vintage machine, particularly one as rare as a PDP12, you should use the
components
that were available at the time. It's not as if a programmable buad rate
generator is hard
to make from TTL either. In fact given the Arduino thing needed 'some
debugging' it might
well have taken less time to do it in hardware.
