I adopted another PC this past week - the source will remain nameless. This one was a rescue and needed a bit of cleaning. The inside of the machine looked decent for it's age. I took apart the full height Tandon drives and gave them a thorough cleaning and lubrication.
Powering up was uneventful, except for a nasty noise from the power supply. It was the kind of fluttering noise you get from a fan when the blades are loaded with something. It was loud and not happy sounding. Peering into it I decided that I needed to get at the fan for a good cleaning. This is what I found:
Ugh ..
This is what it looks like now:
And of course, it's so quiet now that you have to put your hand on the exhaust vent to feel for the airflow.
(For anybody else tempted to try this - I don't normally open power supplies. I'm scared of big fat capacitors. You should be too.)
The rest of the PC was fairly normal. Oct 1982 BIOS, two full height Tandon drives, monochrome adapter, 5151 display, and an AST multi-function card to bring the memory up to 640. The only change will be to put an Ethernet adapter in it.
