PII dual processors - which MoBo?

[~~~^^^mercury^^^~~~]

long ago (feb 15, 1999, to be exact) i acquired a slot1 PII SL2W8

recently received, for recycling, a friends dell: slot1 PII SL2U7

one source indicates these to be quite compatible for a dually system.

SL2W8 => dB0 0652 512K 65 18.7 1,4,6,7
SL2U7 => dB0 0652 512K 70 27.1 1,4,6,7

these are both family 6, model number 5 w/core stepping 2 & 512K
now, i am not certain what the 65 18.7 and the 70 27.1 signify, but
the source i read says 0652 w/512K indicates probably compatible PIIs.

but, if there are issues i am not aware of, please advise

now,
1) what would be the ideal abit dual cpu mobo for these slot1 PIIs?

and,
2) is there more than one mobo that could house these?
abit and not abit (asus, aopen, etc.)

one concern: although the above lists the SL2W8 w/512K, tomshardware discussed specific SL2W8s as having a 4MB L2 cache and listed the identifying markings on the L2 as Toshiba 225.
i did partially disassemble my SL2W8 and saw it was the Toshiba 225.

3) if that is in fact the case, would this 4MB SL2W8 slot1
not be compatible with a 512K SL2U7 slot1?

i forget how, but i think there is a way to determine the L2 cache size.
during boot up, 512K is indicated.
4) is it possible the boot specifies the L2 cache size based on
the sspec, thus the 512K, when the L2 is actually 4MB?
5) is there a sure fired way to read the actual L2 cache size
on a slot1?

a bit of history, if your interested:
i am very partial to my old SL2W8, as that is the cpu discussed long ago in tomshardware for overclocking. this sspec used a manufacturing plan which sold 3 different sspecs variously as 300s, 400s and 450s, even though they were all manufactured, in the same exact process, as 450s.
it was just more cost effective for intel to use one manufacturing process than to use 3 different processes.
the problem, and intel found out the hard way, was that this made for some very hot news among the tech circles, when it leaked out.

my SL2W8 was sold as a 300 for a significantly lower price.
i was told it was a pull from a HP?? system that did not sell.
anyone want to guess the cost, in feb '99

$310 fan included
and,
by the way, i am typing with it now.
it is in an asus p2b (which flaked out, along with the asus graphics card,
during the first year of operation -
picture hair missing.)
that is one reason i am searching here at abit for a dual processor mobo.
oh, and
128MB pc100 sdram cas2 went for $183, and
a fujitsu 10.2GB HDD was $210.

today, nobody would maybe care too much about all this, except maybe a nostalgia freak like me.

curious,

thanks dave rave,

very on target collection for dual slot1s

noticed the IDE drives don't go beyond DMA 33
on any of these 4

"2. Triones Ultra DMA/33 Bus Master IDE Driver
3. Intel Ultra DMA/33 Bus Master IDE Driver"

thought maybe ATA/66 was available for slot1s

never used a GB mobo - will think about giving one a try.

i was looking the abit site ....
some dill has put all the discontinued mobos into socket 478
including the bp6! (abit-usa)
and the .tw site is taking a while to load
there would be a dual slot board in the server section, but i can't re-find it

[~~~^^^mercury^^^~~~]

thanks for looking
i will check it out.

Try looking for a Tyan motherboard - they have no overclocking options but are rock stable. This probably isn't what you're looking for though because they will give you virtually ZERO overclocking capabilities.

[I know... I know... I know... It's blasfamous to even mention motherboards that don't allow overclocking! ]

I think many of us enjoy "rock solid" stability as apposed to extensive cooling mainboard modifications.
