Does setting the turbo jumper change the weak beep? What components did you use when testing the board? Can you try and measure the voltages with the PSU connected to the board? Thanks I haven't tried with a turbo button attached. So far I have just tried with with and without a VGA card, a WD90C00 …

By big trace you're referring to the one coming from the PSU? Did you check the four small traces that ran under the battery and resistor that's next to the keyboard DIN? For the battery, that's a four pin header down the board labeled battery. You can get one of the four AA battery enclosure the …

Yes I always wondered if the Cyrix would be better than a Pentium for things like Starcraft and other RTS games. I'd need to do some testing at some stage.

The forum software is fast and seems good but the theme needs serious work. The Old School theme is better but the font needs to change and the gradient on replies needs to be fixed. I also don't like the power button for login, makes no sense. Actually all the buttons & shadowing are odd. I am also …

Although I love all things AMD. A Celeron 500 should be a lot faster than K6-2/500 in games.

Athlon XP probably has 4x AGP/1.5v so the Voodoo 3 won't work anyway (and may cook something)...

I would also like to try OpenGL on the 6326! I had this card back in the day thinking it would be a massive improvement over my S3 Trio. It wasn't really! It would be cool to test with.

What use is 4.3 or 3.8 volts? I assume the CPU is 3.3 or is it useful for over clocking?

Very cool. Do you need to to convert the signals down to 3.3volts too or it is just the power the CPU runs off running at 3.3v? I don't know much about it!

Yes it seems to depend on the revision of the CPU. I would recommend at least a heatsink on all 486 DX2s.
