That sounds like a Graduate. There were several Torch units; the original
was a Eurocard-sized Z80 processor that fitted inside the BBC and came with
dual double-sided 80-track drives in a case styled to fit under the Beeb.
Notorious for noisy head solenoids and a rather iffy SMPSU. Then came the
Graduate, based on an 8086 (?), followed by the Unicorn, which was a
repackaged Beeb with a Z000 (? or 68000?) running a Xenix derivative.
