OT, but info needed: RAM uprade

Fundamental? No. But about everything else, yes. Remember, I'm of more
ore less a PC generation. Everything before my 486, I learned secondhand,
and not to well. But yeah, I really haven't the faintest.

Hmm... but it still had the half width bus, right?

Yeah, but it's still a 'downgrade'. But the 386SX was a fairly good
success, and I take back anything bad I said about it. But once again, the
386SX didn't give the 386 all it's glory.

Yeah. I'm not argueing with that. Actually, the 128K's at full clock
speed, not half, like in a PII, so eventually, you loose an amazingly small
amount of performance. When you add in the fact that you can overclock the
Celeron a lot more than a PII (a 333 can go to 450MHz, according to some
reports, but I don't have that kind of a cooling system. Tropics, and all.)

>286 never saw a 288 version.

I'd never heard of one. Although that makes sense, as it'd be pretty bad
to have a 2nd generation x86 16-bit processor with some of the 'cost
saving' but no longer necessary features of a 8088.

Yeah, but IIRC, some parts of even the newest XEON based system are 8 bits
(like the BIOS). You've got 16 interrupts, half of which are taken up by
things as simple as clocks, etc. and then you've got a whole bunch of parts
which should share IRQ's but don't... I say it's well past time that we put
the PC architeticutre to rest.
