Sounds like the "standard" 20 MB HP
drive as found in
Vectra PCs and
measurement equipment. I once had to replace the
hard disk
in a HP4972
network analyser and took one from a Vectra. The
controller
board for
the Vectra (standard 8-bit full-length ISA card)
has an onboard
MC6809, on-board sector buffer, a BIOS etc. It's quite an
intelligent
card from the programmer's point of view
(I've partially
disassembled
the BIOS), but lack further information. Would be
nice to write a
Linux driver for that board ;-)
So, they are basically MFM drives with a weird connector on them ?
Any real product number ?
