Witch Vectra do you mean ?
The default Vectra discs I know (ES,ES12,CS VL2 before 1995) are standaard
MFM or IDE.
The (80286) ES(12)'s are using seagate's ST225 or ST255 (option)with a
WD-controller, the VL2 (80486)is using standard IDE 40-200MB (PIO no DMA)
the CS is also using a MFM drive 3.5inch.
The 9153 disc uses a HP proprietary interface I think one of the manuals a
the Hpmusuem discribes it. The biggest problem wiht the 9153 discdrives are
the bearings, the turn motor doesn't have much torque so the disc are jammed
very easily.
Freeing the disc by hand sometimes frees them but not always.

The one I have (actually an HP9154, which is the
smae unit
without the
floppy drive) uses the HP Nighthawk drives, which
have a strange
interface on a 40 pin combined power and data cable. I seem
to rember
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 ;-)
