@ Scott: Yes, have an EtherNet card. It works perfectly in a Quadra 700, but becasue of the built-in port, it isn't needed there, so it would be much more useful on the IIx.

@ Unknown_K: I don't know... maybe I could get a toast MacII some day, and put this mobo inside... or something home-brewed!

@ Byrd: Here you are:

•The rightmost pin (as seen on my picture) is +12V, put the yellow wire from PSU there.

•Pins 2...6 (from right to left) are +5V, the red wire goes on any of them -- it's enough for a brief test, maybe not for 24/7 on a full laden system ;-)

•Pins 7...12 are GROUND -- any black wire from the PSU.

You may like to connect the -12V line, anyway... the blue wire from PSU to the second pin from right @ IIx. I believe the serial ports won't work without it, it's likely the only use of -12V (audio too?)

By the way... if you're using a standard ATX PSU, you have to connect its green wire to ground (black), otherwise it won't start! In my to do list there is placing an inverter between the ¬PWF signal (leftmost pin on my pic) and that green wire, so I get soft power control, as intended.
