This isn't directly related to Vintage Macs, but I thought I'd share it
anyway given the recent topics of discussion and lack of overwhelming
traffic.
I've recapped a couple Mac boards over the years to decent success.
Well, a bit ago my car started running somewhat poorly. Not undriveably
so, but just having hesitation and missing on acceleration. Granted,
it's a high-mileage 1991 Toyota MR2, so problems aren't unexpected with
a car that old. Had it at the shop finally, and the guys diagnosed it to
the main engine ECU computer. They tested all the sensor inputs, and saw
they were good, but saw the fuel injector outputs as bad.
Their recommendation was replacing the ECU, which involved rather more
money than I wanted to spend on such a thing. On a whim, I took apart
the computer, and lo and behold, the board had that familiar corrosion
under a couple of caps.
http://bit.ly/1bAqDzZ
Had no trouble finding replacements and swapping them, and now the car
runs perfectly.
Who'd a thunk that all these years of playing with ancient computer
hardware would come in handy like that. Even my wife is a little more
understanding of my electronics foibles after this :)

I can't see any corrosion.
That isn't much of a computer. Looks like a few ttl chips. Most cars of that age have 2 "computers" afaik. One at least has a board with a uP chip, like an 8088 or a 68000.

Sorry, again slightly off-topic.
Similar story with me with an old Accord coupe. Turned out the main relay
solder had cracked, the skills I'd picked up for resoldering the Mac Plus
(on-topic :) ) helped towards soldering this, got it fixed!

I've got a 92 Caravan (just rolled over 222222 miles yesterday)...it has an
occasionally odd hiccup...stumbles or power loss at moderate throttle...hit
the gas and it pops out of it and is fine. In the back of my mind I've
started wondering if aging capacitors in the computer somewhere might be
causing a problem...they certainly seem to start going out in most
everything else that old! Seems that they are a "wear item" in the
electronics world... :-( A friend says that is often all it takes to bring
antique radios back to life...
I've replaced capacitors in lots of things...an old inverter, power supply
for a wireless router, monitors and TV's, motherboards, an old PC video
card, etc. Definitely a good skill to have! Now if I can just master those
dang surface mount caps... :-) On my list to try again when I have some
free time...

I'd suggest your TPS throttle position sensor first.

Generally speaking, how do capacitors in radios from the 1930's and 1940's stack up against their 1980's computing counterparts (that is, the ones found in Compact Macs) in terms of service life? Let's assume that both the radios and computers in question are in more or less regular use (i.e. the capacitors are maintained).
I find myself wondering if, say, a radio from 1930 could still be reasonably expected to work "as-is" in 1960 (i.e. thirty years or more later) as opposed to Compact Macs, which, thirty years on, more or less *cannot* be operated with their original capacitors.
Best,
James Fraser

The size and "construct" of old radio (and old tube amplifier) caps are vastly different than more modern computer ones. I think maybe your wry point is in the statement somewhere? But I know friends who repair old tube radios and Dynaco Amps, for example, which capacitors have failed creating a noisesome humming and potential and realized damage to other components.
