Yes, for example, an Intel SE440BX-2 with a C3 and MS-6905 slocket is something I'm slowly acquiring the parts for. I'm hoping it gives the same smooth performance increments of my P55c MMX with a wider performance envelope. If you want three ISA slots, obviously you will want a different board. The only proviso I know of is to be sure the board you choose supports the Vcore of the C3 chip you purchase as full on VRM slockets are rare and expensive.

This is why I don't put all my hopes on a single board and collect multiple boards even if it were for a single project should something go wrong, I had that DFI board at one time then lost it along with everything else to arson (attempt on my life and family) and the board can get picky with the ram slots. It certainly didn't feel like it was a quality board but it was quick and overclocked well, of all places that one could get parts I found it in a dumpster in 2007.

VIA C3 is interesting and want to give that a try if my funds were not dry as the economy is going down the toilet again and unexpected unemployment put a halt to my plans.

MS-6905 and other slotkets are readily available and not too expensive, and I can find a board like an Asus P2B easily enough. Can even find Via C3 Nehemiah without much trouble. And the cost for all three together is still less than a Super Socket 7 board. I think I'll pursue this path. Still need to acquire a Voodoo3 for graphics. Voodoo5 is a bit out of my price range right now.

The C3 Nehemiah is okay, but the Ezra chips are better in terms of smooth scaling.

Interesting, gdjacobs. I had thought the half speed fpu would be a detriment.

I want to install: an intelligent midi card, a Sound Blaster AWE64, and a Gravis Ultrasound Classic v3.74.

It's not practical to have them running 100% of a time and 2 ISA slots will suffice. You can also use ISA riser card.

Indeed it is, although the objective is less top end performance than it is the ability to speed tune.

If you dont go with the K6-3 plus, but instead go with the regular K6-3 your motherboard selection increases. Alot more boards support the desktop K6-3 compared to the laptop plus model.

this compatibility list is a pretty good place to start on finding a compatible board, then you can pick your desired features on the ones you can actually locate

gdjacobs: You have a point there. I can find Ezra cores even easier.

The Serpent Rider: No, it isn't. But I'm not going to swap out cards every time I want to use a different one. Nor do I have the space or money to build a second rig just to support that sound card.

vetz: True enough. Even the board I was using will support it. But then I lose the ability to change the clock multiplier in software, which is a key feature of the build.

Super_Relay: I have looked over that site, and while it does help, it doesn't give the number of slots for most of the boards, and half of them don't even show form factor.

Thank you all for your input. It's appreciated.

BCM VP1541/VP1543 has 3 ISA slots and support K6 plus, is based on the ALi Alladin V

its a pity they don't mention whether they had to disable on board cache to get those high fsb numbers
