I am wondering if I should skip the Geforce 6800 build and instead use that MicroATX case for a pseudo 386 PC using a Pentium MMX thats got all caches disabled. The motherboard I have is baby AT. But I have an adapter to allow usage of an ATX PSU with it. The motherboard has header pins for PS/2 mouse, so I'd have to make up something to attach to that header. Looks like it will fit in the case if I do some custom mounts. I will be able to use 1 PCI video card and up to 3 ISA cards. See attached image.

I am thinking that an S3 Trio 64 with Soundblaster Pro 2.0 would go well in this. Maybe with a 4Gb CF card internally and DOS 6.22 + Windows 3.11.
This way I can use my Pentium MMX at full speed usually, but if I need 486 speeds I can adjust it using just SETMUL. No reboots required. Unless I want to mess with multipliers of course. I may add external rotary switches to access the multiplier and bus speed if I find myself wanting to do that often.

I've been working on a very similar concept for 8 years, and the spread seems about right. That big crunch of progress from 97-2003 is crazy and of the 9 systems I have covering 1992-2011, 4 are of that short period. I try to run a different memory/CPU socket generation and windows version as the main differentiator.
Yes, that period of time was crazy with the speed of advancement. Its no surprise that there were compatability issues during this time. I am actually thinking I will use a Pentium II 400Mhz now with the TNT/Voodoo 2 SLI system. It seems more balanced between the 300Mhz Pentium MMX and the 700Mhz PIII.

My biggest advice pertains to the DOS/98 machine and is honestly just to stop worrying about everyone in the retro computing community being obsessed with DOS compatibility on sound cards! It doesn't matter if your 98SE machine "only" has a PCI sound card and is terrible at SB emulation, because your DOS and Windows 95 rigs will have native ISA cards with the real hardware onboard.
Yes, I know what you mean. But since I have the cards. What's the harm? Faster machines are better for playing Duke3D and System Shock for instance.

You're basically there already but another personal favourite piece of advice is to use a couple of KVMs instead of trying to maintain bunch of period-correct monitors, mouses, and keyboards. I have one for VGA systems with a CRT up to 1280*1024, one for DVI systems with a 1080p LCD, and one for DisplayPort on 1440p. Including my "modern" rig that's 11 PCs and 5 desktop Macs but only 3 desks. Go for a Belkin Omniview PRO on the earlier systems because those can seamlessly take PS/2 mouse inputs and provide serial OR PS/2 to each PC.
Yes, we think alike. I have 3 KVMs for different uses.

I even have a joystick/gameport "matrix" with the ability to send any one of 4 joysticks/gamepads to any one of 5 PCs. That one is a cable management nightmare though!
I'd be interested to know more. My intention right now is to use DB15 extension cables and make a panel that has one socket for each PC with gameport. I can then plug my joystick/wheel/gamepad into the PC I want to use it with via that panel.

(An aside-- I don't go older than 486, so for any older DOS games I just set them up with a little batch file to run ICD ... game executable ... ICE for each game. I guess this is sort of like using SetMul but less fiddly to make seamless. I do have a turbo button but I hate having to remember which games need it, and always forget to turn it off. There are probably loads of games this won't be enough for, but they're too old for me to care about them, sorry 'bout it.)
I haven't heard of that method of slowing a PC.
