Well... ;-) There are others in a bits box in Fort Collins.

That makes a certain amount of sense. It's a little bit of a shame not
to use the features of the 710 chip, but maintaining fewer drivers is
clearly a Good Thing.

I don't have any docs for this card specifically. According to
http://www.parisc-linux.org/documentation/hp9000_models.html,
"The two types of EISA-SCSI cards use the NCR 53C710 SCSI controller
at 50 MHz to support either Single-Ended (SE) or Fast-Differential (FD)
SCSI devices. The Series 700 Configuration Guide (November 1992 Edition)
states that the older EISA Card (model 25525A) for FD SCSI devices is
not qualified on the 715/33-50-75 models, and it recommends the 25525B
EISA card for best results on the other workstations."

Well, it was only tentatively working anyway... I shall be in the
presence of the necessary documentation to get DMA working towards the
end of the month and I'll type it all in then.
