and a number of X terminals.
I always
thought the i960 was an upgrade to the i860 (sort of like
i386 to i486 upgrade). However, based on the info on wiki it seems
as if the i960 actually came first and although a RISC chip it was
in no way in the same league as the i860. Anyone can clarify or
verify this?
I'm not even sure I'd call them related. The i960 is a very
different, almost
"normal" RISC chip compared to the i860, though it uses Berkeley
register
windows like SPARC. It has excellent XOR performance, so it got used
a lot
later on in RAID arrays (my Apple Network Server 500 has a RAID card
with an
i960 on it). A few systems used it and it was popular in military
applications
but it never achieved its potential mostly due to internal politics
at Intel --
not because it sucked -- and the DEC StrongARM settlement mostly put
a stake
through it.
