I think the greater number of them supports the 3,5 multiplier. I have four 200mmx chips and all like the 3,5 very much. Two of them also like 2,5x100 (250MHz) without overvolting on super 7 boards. One even got to 3x95 (285Mhz) at 3,0v. This could be an escape if your MMX dislikes the 3,5 …

You could look into the IBM model 30-286 if you want history. PS/2 brought us a lot of standards, including VGA and the mini din keyboard and mouse connectors. The model 30 isn't that fast, even for a 286 I'd call it slow. But having 16b ISA on a PS/2 makes it compatible with the market (instead of …

Thanks for the replies. To downclock you could always run the P3 at 66MHz FSB. The CPU will work at that speed, no matter if matches another actually existing CPU. As for power linearly scaling, I was under the impression that lowering voltage had more effect that lowering clockspeed. These tend …

Wait a minute here... My IBM PS/Valuepoint 466 is playing picky about ram with the same kind of error: post test counts way too far and gives me a mem error. So by resetting the bios this way it could be the solution? (Did I smell some 32MB ram somewhere?)

Nice build! To be honest I never took any case this far apart. This is some serious maintenance! :D Gonna follow this thread (probably mostly silently). 10/100 Network card - can anyone tell me what the cable that connects to the board does? My guess it's for the power on signal from Lan. Quite a …

Second: few nice controllers. 16b SCSI / floppy combo, 8b SCSI "floptical"(?) Controller and some generic VLB dual IDE I/o card. Not sure is the second one drivers hard disks, but it's nice :) Actually that 8bit scsi card is nearly same as a Rancho RT1000 Value Stor (same FCC ID) except missing the …

Id rather have a 286 tbh. Especially a later fast 20/25mhz one. Those start to enter 386 performance territory and IMO are much more interesting than a 386 machine. Anything that definitively needs 386 instructions and horsepower would probably be better off on a good 486. To be honest, I agree …

I received my package today and I'm having some mixed feelings. Most stuff looks good, some look like that have been laying in the rain. First up: two little Lan cards, one BNC, one rj35. The latter may become in handy. And the Yamaha YMF719E-S based sound card. No atapi, but I think it's a nice …

Bought this lot today. It has quite some interesting stuff! All untested, but I have bought some untested stuff earlier from this seller and all was fine. He's not a vintage collector but trades in newer stuff, and doesn't seem to have much interests in vintage stuff. The 8b ISA SCSI adapter and CPU …

In my experience, there is something to win. I have got a Trident 9420 VLB with 2MB and it performs well enough in dos and Windows. The Cirrus 5424 VLB I have is about 10% faster in benchmarks. These cards are not hard to find and still affordable. The Diamond Viper I had, was slow as *** in VGA …

Getting the AT feeling... I think I get fairly close with my IBM model 30 286 10MHz, with 1MB and integrated basic VGA card. I hardly use it. I've got a couple of dozens retro rigs, and my favourites for gaming are the Philips P3105 (8MHz XT, CGA, software turbo) , 386 DX40 (8MB, S3-928) and 486 DX2 …

Thanks for your experience, what stop me now is the fact that mine board come with only 64kb of ram. Expansion boards usually can be set up to support existing ram from 64 to 512kB, set by jumpers for offset. Just take care for which you pick and look it up on TH99 for easy setup In my stack of …

Is your CF industrial class? Then it shouldn't be much of an issue as they are designed for this sort of tasks. They can handle far more r/w ops than non-industrial. You say the swap file is set to a mechanical HDD. That's a good thing to expand lifetime of the CF. On the other side, it's a bit …

If you plan to use graphics for both DOS and win 98 on a Pentium 2 450: TNT2 would be an affordable choise. This provides good DOS / vesa support and has good Windows drivers for directx. Voodoo will be fine too, but is more costly. Faster Nvidia MX cards would be fine, but there performance gain …
