Motherboards

I found a box with a load I got with a bunch of so called Mac trash. All bags marked non working no boot. On a whim I took a power supply from a 6100 and plugged it into a board marked 660av and bong it starts to blinking floppy. So there is a quadra 840av board also if I can find a power supply for it I may have to hack some old G3 enclosure to make them working macs again.

really a quadra 840av board :-D

Cool!

Ya well I don't know if I have a power supply to test that one. Second like gonna be interesting sticking one in a tower which probably won't work as they are so long.

I'm pretty sure you can use any of the following PS's to test the 840AV on the bench:

IIcx, IIci, IIsi, IIvi, IIvx, Q700, C650, Q650, Q800, PM7100, PM8100.

I may be mistaken, but as I understand it, the Q650 and the Q800 are the same circuit board with slight clock multiplier resistor and gestalt resistor differences. So power supplies for one should work in the other, and by the transitive property, the rest follow. But I may be misremembering something....

Cool I got a 650 and some IIs so ill try that out.

Thank you.

Ok I was looking around on flickr and found the one board i have is not an 840, its a 950. I guess the hard part is getting a power supply for it. The other board im thinking may not be a 660 because the power supply from a 6100 works on it. So maybe a centris, only thing that is throwing me off is it has av in and out rca jacks connected to it(from wire plugged into motherboard). Got flickr working just need to upload some photos and ill start posting lol.
