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.
As I understand, 1541 drives read / write in a different format to the 8250
drives. The 8250 is able to write 1Mb to each disk which I don't think the
1541 can do.

Maybe he has some 8250 disks to read? Perhaps some (custom?) software that
needs a disk larger than a 1541 to work?

He didn't say, but he could have one already. I have one for the C-64 and
one for the VIC-20.

It's possible to build your own with a VLSI I/O chip (6520/6522/6526)
and a couple of buffers. That plus a ROM is what's on my VIC-20 IEEE
adapter. IIRC, the drivers are a 75160/75161 pair, but there are a
couple of options.
AFAIK, there is firmware for _some_ IEEE adapter on funet. Not sure
which one without looking.

If he wants to move up to a 128, that would work. Personally, I _have_
a 128, and I'm more likely to fire up a C-64 that it, largely due to
experience and personal comfort.
