Hi Tony,

Aha....you have detailed technical docs on the machine???

I managed to get a "service manual" several years ago but it has nothing even
remotely useful in it.... :-(

Sorry, I'd misunderstood what you meant.

>the heads are different to the PC drive ones....

Augh, major brain fade....you're correct of course, the Sirius uses 80 track
drives (I'd been fiddling with an XT before I wrote the message).

What I think I was getting at....is that pretty much any 80 track drive from
that era should work, as long as you can remove the analogue/motor control
boards (which isn't usually possible on more modern drives).
