I am trying to find an M-ATX Socket 370 board that is not limited to Celerons / PPGA / 66MHz FSB. These are pretty expensive on eBay but I have found an HP board that is a lot cheaper:

HP 203966-001 213855-101

The CPU in the board seems to be a 133MHz P3 but the only worry I have is the ATX connector. It looks standard but does anyone know if it is proprietary or a standard ATX?

AMD DX2-80 | 16MB RAM | STB LIghtspeed 128 | AWE32 CT3910
I have a vacancy for a main Windows 98 PC

Service manual for the Deskpro EX here. Section 7 about power seems to detail the 20-pin pinout.

Thanks very much, it looks like it's a Standard ATX connection.

Yes, can confirm. It's a Compaq board, not HP (pre-merger, but listed as HP now), and it's ATX. I have a Tualatin-ready one here. Very decent for OEM stuff, quite unlike what Compaq was doing just a year earler.

That's reassuring, I'll be putting an 800 to 1000MHz CPU in there so nothing crazy.
