I did not see an answer to this.

I am not aware of the existence of the card you need, but that doesn't mean it
does not exist.  I was going to suggest another way of using your old
Differential SCSI drives on your 918LX.  You could conceivably get a
Differential to SE SCSI converter box along with some good cables.  Try
www.paralan.com.  They have such gadgets.  Your setup would be:

SE controller on the 918LX connected to the SD10B converter on the SE side via
a SCSI-2 (50 Pins) to SCSI-1 cable (Centronic).  The converter will do the
Differential to SE conversion.

On the other side of the SD10B converter, you would have a SCSI-1 (Centronic)
to SCSI-3 cable (68 pins) connecting the converter to the disk drive(s).  This
will do the wide to narrow conversion for you.

You would then configure the WC drives as N drives to reflect the fact you are
using the narrow SCSI card.

Works fine, lasts a long time, at least for DLT drives.  I am not sure if MPE
will complain about seeing a WC drive when you have declared it as an N drive.
 You want MPE to use the proper driver, which in this case would be
SCSI_DISC_DM_LOGICAL_DEVICE_MANAGER  and not use the regular one
SCSI_DISK_AND_ARRAY_DM_LOGICAL_DEVICE_MANAGER.

The converter will cost around $350 and the cables could run you up to $100.
 It might be cheaper to dump the drives and get new ones, especially in these
days of increasing drive capacities and shrinking drive prices.

Subject:        HP3000 918LX and 16 bit diff disks

I have a number of old HP6000-SX shelves filled with DEC DSP310LSW
and Seagate ST34573WC drives which were used previously on my HP9000-k420.

I have since upgraded that machine with a Jamaica box and would love to
use these disks on my 918LX, which has a Seagate ST34573N SE SCSI system disk.
I have found that I can't use my old HP-PB 28696-6001 16 Bit DIFF scsi card
on the 918LX (it works on the 918RX, wouldn't you know...) apparently
because there is no double high HPPB slot on the 918LX.

Is there any 16 Bit DIFF Scsi card that anyone knows of which works with
the 918LX?

I suppose that since these were on a differential card there is no way
to use them on a SE bus. I am a little surprised that HP would create a
machine as unexpandable as the 918LX, with only two 1/2 size HPPB slots
and a 8bit SE SCSI bus.

Thanks in advance
Paul
