Err, the main board is not something you replace. It's something you
_repair_. Most of the chips on it are not hard to find...
Incidentally, if said technician doesn't realise this, it's time he
started looking for another job!
The reason that I'm looking for it is that my
father has been using his
8250 to run some software and his has broken. He's had a technichian
look at it and some parts are needed. It would be easier to buy another.
What parts? Drives? Power Supply? Main board? The main board is
about the only thing that really is hard to replace.
I don't know what specific disk drives shipped with the 8250LP, but if
it's the drives themselves, it's probably possible to find an equivalent.
Be careful, the drives are a bit strange. For one thing, I think they
might be the 100tpi (not 96tpi) units. For another they have no
electronics with them -- there's a little PCB between the drives that
carries the read/write electronics, stepper driver, etc. A normal drive
will _not_ plug straight in.
Good luck in your search. All of my PET hardware is
older than that.
I have never even seen one up close, but they are out there.
I have one. I also have schematics...
