Hey! You're right! Our 320 machines (320E,
upgraded from 320 something
else I think, equivalent to 320H) have ethernet on a microchannel card.
That shouldn't be too hard to find...
They are a bit hard to find, and I do not think a PS/2 "dumb" MCA ethernet
card will work. I have seen more token ring cards around, probably because
nobody wants them.
For a while, IBM repackaged 320s as model 6011 Network Processors -
essentially a AIX box with two or three routing cards. They were a spin
off from the NSFnet routers, although the 6011s routing cards were not
homemade. I do not know of the 6011 could handle the HSSI or FDDI cards -
I have never seen any.
We've had our 320s for six years or more, our 375
for four or five. We
are thinking of getting something faster but it's hard to match the FP
performance on anything modern. With luck, when (if) we do, I'll get
the old ones. FWIW the fastest FP we found in our sort of price range
was the RS/6000 model 397. The last of the POWER RISC machines, much
faster than the Power PC RS/6000s...
The POWER2 series (990 leaps to mind) is an excellent floating point
machine. Look at the LinPack rating, and the results are impressive (not
that one should treat LinPack as the bible!).
But I fear we're a bit off topic here...
Yeah, but so is the whole NeXT thread!
Give it a year or two...
