Default power supply PL800

hi,

currently re-builing a PL800 but I'm afraid I touched the chassis
with one of the red power cables
does anyone know: is there a fuse somewhere inside?
if not what alternative I gave, can I use any kiind of ATX psupply?
would be nice since then I have room for a second one which enables me
to put en extra one in to create a more balanced load on the unit.

The PL800 uses a proprietary power supply. There is a fuse inside it, but if
the fuse is blown a 99 percent chance the power supply is gone. Are you
sure you didn't fry the mainboard?

That unit is not worth investing much if anything in. 600 MHz cpu's the
fastest it will accept. By the way, that power supply rarely gives trouble
unless it is helped. I don't recall any PS failures in the 800's If you had
the PL1600 or ML370, some versions may have a hot-swap redundant power
supply in it. They came in two flavors, the single power supply like the one
you have and the redundant power supply that accepts 3 smaller plug-in
supplies.

We have the original 800 supplies as well as the redundant version of that
PL1600 and ML370 power supply if you need them, cheap.

Ya, that old 800 was perhaps one of the most dependable units they ever
built. Technology/speed did it in. Those old "three bangers", more popular
in the 1600's were useless to me. We had/have all dual supplies in
everything but it's fed from two different power sources so it would keep
going with loss of a leg on the power line. That three banger had to have
any two going or it would shut down. Was useless in my application.

The way things are going, before we kick the bucket the computing power of
our best ones may be contained in wrist watch style. I can see it now,
looking at your wrist computer and saying .. "computer, what is .. " and the
"computer" responds.

Scotty, beam be up !!
