Not meaning to derail the thread but,
Going down the same road as the OP recently myself. I ordered two slotkets, one with jumpers and one without.
Having only a a handful of Socket 370 chips, and all of them but one being 133FSB models, I also ordered a 1100mhz Coppermine Celeron to test with.
I've got a few Intel Seattle boards to test with, one Dell and one the retail variant as well as a MSI non -AGP slot1/370 combo model, and a Asus HP OEM board.
Nothing great, but the Intel boards are solid, the Dell is in the original PC an XPS t450, currently running a 700mhz P3.
The retail variant is my go to retro machine at the moment and is currently running a P3 850mhz.
I've also got a Nehemiah 1.2 that works fine on the MSI, that I'd like to try on the Intel boards. Research indicates that it SHOULD work with at least one of the slotkets. Time will tell.
I'm curious as to how the Celeron 1100 with compare to the 850mhz P3 with the same hardware.
I think that it will be fairly close, maybe a bit faster due to both chips having 100mhz FSB.
There are a few SL5QV on ebay, I'd like to pick one up, but it's hard to justify as I have the 133mhz version and a good working socket 370 board if I ever want to use it.
I'll probably give in at some point, but I'd like the hold out for a SL5QW to crop up cheapish. I'm probably dreaming there.
The Celeron was like $11 shipped.
