??
One huge advantage to the 780 is there are almost no
custom parts in it, other than
the LSI-11 which is still pretty much available, if needed.? The whole 780 CPU
was built out of 74Sxx chips, and could probably be maintained for another
50 years if one wanted to.? The only custom sort of parts would be in the
power supplies, which would be easy to swap out with generic DC supplies
if you couldn't repair them.

Agreed. The one place I am going to start is with the power supplies. I plan on running
this on
single phase at least initially. I don't see anything in there that needs 3 phase.
