I seem to remember that the PSU outputs were good - at least everything
was as it should be at the drive connectors. The machine's in storage
about 200 miles away from me at the moment, so unfortunately I can't
check (one day I will get a place with a bit of space!!!)

I never stripped the machine down and rebuilt it though.

Heh heh, yup - I remember doing exactly that...

The monitor is getting HT power to the tube OK, and from what I remember
the ribbon cable would only plug in the back of the system unit one way
round, so that should be ok. It bothers me that there's no cursor or
anything on the screen, but I don't know if there should be - chances
are good that what little ROM this machine has would contain just enough
to boot from disk and nothing else.

It's a shame that the disks I have aren't known to be good - I have 2 or
3 system disks but all of them give the same results - disk seeks and
spins on power up and then all goes quiet.

let me know when you get your Diamond running! :)
