This is in response to a question regarding repairs to the IBM logic and
the video display.

The flyback is a quite common transformer which most T.V. parts supplier
will be willing to sell. The cost would be around $20 . The type might
be decernable from the actual unit but most often a good parts man can
find one of several replacement types. When installing, first wash your
hands very well to remove oils and salts which can cause arcing problems
on the transformer body, then, if soldering any wires, when soldering
create smooth well rounded balls without peaks if soldering any wires.
The printed circuit board soldering needs only normal soldering methods.

The cost of replacing the entire board could be avoided if taken to a
good technician. I found a tech. who works on 8085,8086 and Z80
machines. He charges $100 minimum which covers the first hour of his
work. Parts are extra. But he repaired my Z80 machine for $165 which
beat the $480 replacement cost although it did take him 3 days.
