Thanks for that, Curt and Hans.

I'm now going to have to delve thru the layers of shielding to see exactly
what's what now; it's been a couple of years since I last had them in bits
when the machine wouldn't boot because the drive had seized. Mine has the
ribbon cable between the 2 boxes, but I remember thinking it looked like
some sort of SCSI/SASI drive though, not MFM, or did some 3 1/2" MFM drives
also have the berg style connector on?

There's not a lot of info on the web about this machine and the PC2 and PC3
either - I would've thought the likes of would have access
to all the details.

Oh, and if you fancy parting with one of the drives I know someone in
Belgium who's very interested :)
