as long as it is done in a way that it can be restored to its original, i 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.

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.
