I'm not even sure I'd call them related. The
i960 is a very different,
"normal" RISC chip compared to the i860, though it uses Berkeley
windows like SPARC. It has excellent XOR performance, so it got used a
later on in RAID arrays (my Apple Network Server 500 has a RAID card
i960 on it).
Thanks that explains most of what I have seen. I have also seen it used on a number of
SCSI controllers of yore and I believe the HP LJ 4 also used the i960 for its processor.
Outside of the Hauppauge 4860 I don't think I have ever seen a PC architecture board
with the i860 and I am not even sure how much use the Hauppauge board got out of the i860
except for video processing.
