Is the P166@100 running at 1.5x66? I don't know much about your specific overdrive, but sometimes overdrives were stripped or certain features supported in the standard version. The DX4 overdrive doesn't support 2x multiplier, while a regular DX4 does (for example). Yes, the motherboard only …

Well, damn. Pentium Overdrive 166 didn't start on this board. I'll have to check it on a proper Socket 7 board to see if the chip is actually alive, but it all seems pretty weird. I mean, why would regular Pentium 166 work (although at 100MHz), but an Overdrive (non-MMX) won't?

Maybe you switch between processors using one of the typical key combinations used for switching between turbo and deturbo mode on other machines? That is definitely how it’s done, but judging by the Tandy model of the card, you need to either load a .sys driver or use a utility for that. I don’t …

Very interesting ! I never saw a CPU upgrade card that actually had the removed 8088 plugged back into the Upgrade card. I think for XT accelerators that is actually a norm rather than exception. The odd thing here seems to be a lack of a hardware turbo switch Will look around but do not think will …

If it’s a 100 cpu is that 66x1.5 or 50x2? If that’s 50mhz x 2 I wonder if you couldn’t run a k6 2+ in it at 2x=6x multiplier and use a jan bios patch?

Funnily enough, shortly after I've found this thread, I found a decent deal for a Pentium 166 Overdrive.

A Pentium 3 with an MT-32 seems like a mismatch to me. An early 90s system would be a lot better. I think it's not just a mismatch, but quite a few MT-32-capable games might simply not work on a P3. I remember that some Legend Entertainment titles (like Superhero League of Hoboken) didn't really …

If you're only using it for games, any version of the SC-55 is going to work fine.
