What sort of reliability problems did you get? I find it hard to see
what sort of thing might have been the trouble - it's not like there's
much to a 475.

A lot of power supply problems (not including the one I plugged into the
240V connector, alhtough it definately had one later!),

Huh?

My Performa 475 has a 90V-250+V 50-60Hz PSU.

The american ones didn't. They had switches. Maybe it was a
LC475/performa thing.

More likely a US/Foreign thing, I reckon.

Yes, more than likely

some overheating
problems in a couple

???

How the hell did they manage that!!!???

by getting hot I would assume.

Umm.... Yeah, but, erm, given the nature of the beast, it's a little
hard to see what they could have done to cause that to happen.

There's hardly anything in the damned box, none of it kicks out much
heat, and the fan just sits there whirring away. Yes there is an
expansion slot - but only one.

Not the computer, it was generally the power supply that overheated.
Not much else to go bad.

Blocked vents, maybe? Sat next to a heat source? I dunno.

Nope. Manufacturing defect I would assume.

We also had trouble with 630s (I think that was it) with batteries.
Actually the 6100 was bad with the batteries, if it was slightly flat it
wouldn't do anything.

Uhuh.

475s won't boot with a flat PRAM battery.

Neither would the early PPC ones.

I think my point was: this wasn't a `flaw of the early PPCs' so much as
`what Apple made Macs do at that time', if you see what I mean.

Fair point. However, the flat battery was one of the last problems of
the earliest PPCs. They were definately a 'rushed out in a hurry' thing.
