It was a groupbuy at cpu-world.com. I'm pretty sure the seller doesn't have any more, or I would've seen an option for another groupbuy. They are seriously good at spotting these kinds of sales 😉

In newer stuff, the pin is sometimes used for monitor identification... basically allows the graphics card to autodetect what resolutions and such the monitor supports. It's not critical, but I'd be hesitant to go ripping the pin out if I were planning to use the cable with other things. Probably …

Yeah, the split voltage support was basically the only difference between the two sockets. S7 had one extra pin to allow for that, but everything else was the same. There were some early "Socket 7" boards that didn't actually support the dual voltages, though, which does make things a bit confusing …

Could be a problem with your PSU, try another one. Unfortunately, the PSU is OK. I know that for a fact, because I'm testing 2 identical FX5950s. One works, while the other doesn't. I've tried them both a couple of times, and the same symptoms appear for the defective one. Have you tried google for …

I'm thinking he's talking about pin 9 on the VGA connector being blocked off, which was fairly common on older VGA cards. Ok, thanks for clearing that up! I wasn't sure what he was referring to ;) So now the next question would be:Does this pin (which will obviously be missing from the VGA cable) …

Okay, well I first have to get a monitor adapter because the plug on the 486 is NOT a standard 15 pin, it's a 14 pin. So I will go searching for an adapter. You mean the graphics card? Maybe it's easier to simply use another graphics card? 486's only have pins on the underside. They are supposed to …

Tetrium, what was your prognosis of the Cyrix 5x86 - 133? Does it have a 4x multiplier in it? Does it run stably at 33/133? I have two systems which run exceptionally well with the Cyrix 5x86 - 120 in WinNT4 and Win98SE (all enhancements turn on, except for branch prediction). I would be interested …

You could use a volt meter with a needle for that, at least that's what I was thinking. Personally I rather have the simple adapter as I find the Voodoo solution very cumbersome. Would need only 3 such adapters as I proly won't use more then 3 Voodoo3 3500 rigs at the same time 😜

Yes, I always liked the Coppermine/Tualatin line, but as soon as CPU computational power exceeded what Tualatin could deliver, I'm go Athlon (XP/64). I'd love to have one of those post-netburst boards in a rig of mine, but alas, can spend every dime only once, right? :) Edit:And I think Intel …

PSU defective? And I don't think the TUSL2-C needs -5 volts, iirc that was an ISA thing, which the board doesn't have anyway. And could you post a pic of the unit (so it displays it's stats) or write it's FULL stats on here? Including brand name and PSU model number

You know in retrospect for Slot A Athlon vs. Coppermine, I think the enthusiast world was way too thrilled by Athlon. You got a much hotter CPU with really shitty motherboards and performance that was essentially the same or intangibly better. Tbird was lucky that Willamette sucked hard and was hot …
