AFAIK, the only really custom part in the PCjr is the video gate array.
There's a couple (?) of ROMs of course, but the rest of the stuff is

I tried to make that decision too. I avoided the early 80's home
computers, with their ULAs, etc.
And then the problems started. I had to have a BBC micro, right? Even
though there are a pair of ULAs in it. And that led to be wanting, and
eventually getting an ACW....
And I fell in love with HP machines, particularly desktop 'calculators'.
The early ones -- 9100, 98x0, etc were OK. Just transistors, and then TTL
and simple PROMs. The 9815 was a 6800 system, and I could fix that (apart
from the thermal printhead hybrid). But the 9825, 9845 had custom hybrid
processor modules, the 80 series are all custom chips, and so on. I
reluctantly added them to the collection... The HP9000/200 series are OK
(68000 + TTL + PALs + not too much else), the 9000/300s seem to have big
ASICs in them next to the processor.
Oh well... My justification is that they're beautiful machines, and if
they fail there's always a chance I'll find another one with a different
fault. Might as well enjoy them now -- but not depend on them.

That worries me. How can you own a machine for more than an hour without
cracking the case and seeing what all the chips are?
