Nice fix!  It always amazes me how little of the inside of this sort of
machine was actual digital electronics, and how much was power, video and
sometimes drives.  I brought a TeleVideo TPC-1 back to life a few months
ago, and your restoration brings back memories (some of them cringeworthy).

A few months ago I picked up some Polycorp Polys, a computer designed
specifically for the educational market in New Zealand.  One worked and one
didn't.  The latter is now fixed.  As usual I've written it up with lots of
pictures.  If anyone is interested you can read about it here.
