I'd be interested too if the machine is in Europe  ...

Re: Plotter + Tape drive

Hi Andy,

I too would be interested in the tape drive and plotter - I can collect 
postcode ME1, so not too far away

Regards

Peter

It is SCSI.
You are one of two people interested both of whom have transport problems.
I REALLY don't want to pack it for transport though there a few courier firms 
that could send it
collecting from here (I'd probably put DPD as the most reliable that knows this 
location)

If you're keen enough the way I might suggest if you're in a reasonably 
accessible part of Germany (Germany is a big place, Bavaria is probably too far)
would be to drive to Hook of Holland; take the ferry to Harwich; then drive 
here (Rayleigh Weir - less than an hour from Harwich)
then return in a similar manner. No idea whether air freight from Southend 
airport (less than 10Km from here) would be practical and affordable.

Don't commit to spending money until I have some more response from Dave Wade 
(other interested party)

Andy

If the drive is the SCSI version, I'd be VERY () much interested!

I'm located in Germany. Must think how to get it here in case that I
could get it.

Kind regards

I  had a 9000/375 that would not start a couple of years ago - I think that 
there was a coin cell on the motherboard - once this was replaced, the machine 
booted fine.

Yep yep, I replied to Lee (thought I'd replied to the list, apparently I
don't know how that works anymore) and apologized for not being specific
enough :).

Yep, I found that one, but it's not useful for actually repairing anything
beyond basic board-swapping.

It's not the supply, I've tested the supply, and I've tested the board in
known-working chassis and it behaves identically (all diagnostic LEDs on, a
buzz coming from the speaker, similar to the short one you normally hear at
power-up, but forever.)  It seems like it's probably not coming out of
reset but that's just a guess.

Thanks!
