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!

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.

I have one. I also have schematics...
