Just to add a bit more to the Socket A equation: Consider hunting down a Mobile Athlon or even better a Geode NX: The Geode NX 1750 (1.4 ghz, 133mhz fsb) has like a 25 watt TDP and the NX 1500 (1 ghz, 133mhz fsb) is something like 9 watts. Last time I checked they could still be found NOS on fleabay …

So I've noticed that it seems most of the older ISA boards i've found typically have a couple of slots with unpopulated 16 bit isa slot extensions. My Peak D/M based board has a total of 8 slots but only 6 of them are fully 16 bit. Is this just a cost saving measure, or is there a more solid …

I suspect you want a Matrox card of some sort. They got into the DVI biz early on.

I don't think a C3 Nehemiah would be able to take advantage of anything faster. Only if you play in 640x480 mode. 1024x768 and higher, in many cases, will be bottlenecked by Voodoo 3 fillrate. Eh, not that big of a deal to me. I have other systems that can pick up the slack, like the Slot A system …

Noticed a damaged tantalum cap on a Intel 16 bit ISA NIC I got. It seems to be tied to the shield of the 10Base2 coax connector: I looked up the Philips chip that handles that capability but the datasheet doesn't mention what value the cap should be (unlike the 10Base2 chip on the 3com NIC I have). …

I'll second using a Solo-1 based card. If there are unpopulated pads for a Wavetable header, its as simple as soldering on the header pins and it just works. The ESS cards are the sound card equivalent of a Swiss Army knife.

With a K6 300 (bottlenecking), I've seen temps reduced by up to 4 C load and idle by downclocking from 143 to 100 MHz, with 0-5% loss in performance up to 800 x 600 (tested in Quake 3, Need for Speed 5, 3DMark 99). So not a big reduction in temps, but also no clear benefit in running the card full …
