Yep, ours certainly has three ESDI Maxtors in it - I don't recall if they're 
320MB or 360MB now.

It's got a SCSI (external) tape unit with it too which is via some flavour of 
Adaptec controller (presumably the 1540B that Steve mentions).

We were lucky (thanks, Pete!) in that ours was a full CAD system with the 
faster CPU board setup and the 5085 graphics processor cabinet / 5081 display, 
plus it came with a boat-load of manuals and disks. Definitely a very weird 
and wonderful system :-)
