Issues with IIvx and Performa 600.

So I'm starting to go through my collection to decide what to keep, and what to dump, er, pawn off, er, offer to the MLA members...

The first two are a IIvx (that I have never even tried to power on before,) and a Performa 600 (which worked last time I tried, although it had "issues".)

Tried to power on the IIvx first. Nothing. Not even the slightest sign of an ATTEMPT to boot. Just to make sure the Performa does something, I plug it in to power (and only power,) and hit the power button. *BONG*. Good. Power off.

Hrm, well... I have this Performa 600 sitting next to it, so why not cannibalize the power supply? After all, I'd rather have the IIvx than the Performa. Swapped the PSUs, and the IIvx is still dead as a doornail. Took a closer look at the motherboard, and it looks like something leaked all over where the power and data cables plug in. Well, crap. Writing this guy off.

So, over to the Performa. But wait! I have the drive stack from the IIvx sitting pretty right here, complete with AppleCD 300i (caddy-load,) and bigger hard drive. Let's throw those in the Performa! Try to power on the Performa, no video. (To a "Macintosh 16" Color Display".) A quick check of LEM seems to state that the P600/IIvx onboard video may not be able to handle 832x624. (Which would surprise me, but whatever.) So I dig out my box o' cards. Try an Macintosh II Video Card. No video. Try a Display Card 4•8 with RAM upgrade. No video. Try a 'native' Display Card 8•24. No Video. Try a Radius PrecisionColor 8-XJ. No Video. WTF? (Yes, the monitor works; I unplugged it from my WGS 7350 that was displaying to it just fine.)

Fritzin' fratzin'.....

Anyone want to trade a working IIvx motherboard for a complete Performa 600 system plus a nonfunctional IIvx motherboard? The Performa worked just fine a year and a half ago...

I'd say it could be the caps, they seem to be reaching EOL on a lot of machines of this era (I have 2 LCII boards and 1 LC475 board, all from 1993 vintage machines that need recapping), not to mention that you said that something has leaked on the board on one of them.

Yeah, that was my thought at first, but there aren't any caps right near where the apparent leakage is. And the closest one looks just fine.

Also, I would have thought that leaky caps would produce errors of various kinds, not a complete inability to power on. (But caps may be at fault on the Performa, although its board looks just fine.)

If you didn't live on the other end of the country and they weren't so heavy (read high shipping cost) I'd take them if only for the cases. I have a few Quadra 650/700 motherboards looking for new homes and those cases work beautifully.
