Some of the smoke came out of my Osborne 1 this

appear to have been fatal, as it was still functioning when I cut the
power. I'm giving the CRT some time to fully discharge before I open
it up, probably next weekend. It was probably a failing capacitor,
although it didn't explode, it merely got really warm over a period of
hours. But since there are some similar machines that I haven't
recently used, this question came to mind.
Oh my, this has nothing to do with either the CRT or any electrolytic
cap... I've had the same effect on an Osborne 1, and it was simply the
filter capacitor in the power supply that let its magic white smoke out.
The machine was still running though. Just replace that cap and finito...
