I said "was near impossible", not totally impossible. If you notice #11 is just below 233mhz and 7 of those 10 that are 233 or higher are by the same person and there is no mention if they run stable, just a CPU-Z screen showing the speed. I found it very easy to get my 512KB cache PentiumPro 200 …

the Pentium 200 could arrive to the games of 1999 even without a 3D card? Considering that it doesn't handle 3D well it could be useless right?

What's so expensive at repairing a PC ? Capacitors cost just a few cents, SD cards + adapter cost 20 bucks at most and other parts can often be gotten for cheap in lots, but they don't fail that often and they often cost more when you're looking for something specific. Fixing my Compaq Deskpro 386s …

See if you can buy the keyboard alone for €5, you will make more money that way for sure. ---- The seller might not know. PCs are difficult to onsell due to weight and postage costs, and the fact there is nothing special about it. Good model M keyboards can sell for hundreds of dollars. All I am …

Do you think it is a good investment to buy them and then …

How high can I raise the voltage when overclocking? I tried 2.5V and it throws VXD errors at me in Windows with a 5.0 * 100 config. The K6-2 450 AHX most likely can't be overclocked. It's kind of factory overclocked already with the 2.4V, because normally the K6-2 run with 2.2V only. mine goes …
