Erik,
I recently had an OCC-1 that blew something in the PSU. That odd thing was that it kept
working! I wasn't really intersted in it so I gave it to Glen Goodwin. I expect that
he'll troubleshoot/repair it soon.
The PSU in my BBC Acorn also blew a cap recently. I pulled a cap (0.1Mfd 250 VAC) from
a commercail PSU that I found in a scrap pile and I'm going to use it to replace the
one in the Acorn.
The good thing about working on switcher PSUs is that component failures are usually
obvious!

I am currently making one good OCC1 from two units.
I actually have a working system (thanks much to Don Maslin) as
of a couple of days ago.
Related to this post, though, is that the non-working system has a
power supply problem and I wonder if that resister is it. Which one
is it?

In fairness, the smoke is most likely coming from a burning resistor in the power supply
(I have had this
happen in several O1 computers in the past) and is a $.30 5-minute repair.
