Hmm, almost certainly not - these manuals pre-date the Domesday setup
far as I remember.

The Winchester service manual (available on various websites) has the
Acorn Winchester interface (i.e. SCSI adapter) schematic in it I think,
but I'm almost certain that's different to the board used in the Master
Turbo for the Domesday system. They're certainly different shaped
boards, but I'm sure I remember seeing a crystal clock on the Domesday
board, suggestin a different animal.

Going from memory, there's not many chips on the Domesday controller; if
nobody comes up with a copy of the schematic then pester me enough and I
might draw one out from the board in my system.

Yes, generally a bad idea trying to put together one in stages for that
very reason - getting the necessary copro board isn't *that* hard, but
the SCSI boards aren't exactly common!

By the way (for anyone on the list with a Domesday system), I have the
Master AIV technical user guide scanned, plus I have the player user
manual and player service manual (and borrowed trackerball manual) which
I would like to scan at some point. What I don't have - and I assume
exists - is a user manual for the Domesday system itself (i.e.
explaining the navigation system etc.).

If anyone has that and is willing to scan, it'd be appreciated. I can
take another look at the museum sometime, but I don't believe there's a
copy lurking there either.

cheers
