Hey all. I have a IIcx that's been working fine up until last night, when I tried to install an ADB-PS2 adapter to use with a Logitech mouse. The adapter didn't seem to work, and worse, now my ADB ports don't seem to work at all, except for the power button on the keyboard. The Mac boots normally, but the keyboard and mouse aren't responsive. They both work fine with my IIci, so I know it's not the keyboard and mouse itself.
I can't get them to respond regardless of which ADB port on the back I use (except as I mentioned, the power button). Could this be a leaky capacitor problem, or did I just hose my motherboard? I know my caps are starting to go, as I don't have sound to my speaker anymore. I'm hoping that's the issue, but there's no sense in trying to recap the board if I've killed my ADB anyway. :'(

I was afraid of that. The ADB-PS/2 adapter is for mice, specifically this:

So ummm...anyone have another IIcx mobo with a socketed processor? :'(

the ADB jacks can handle more than anything you would want to shove in a mac electronics wise, so unless there is a physically broken plug the jack itself is not at fault, maybe some of the electronics
and yes they do make ps/2 adapters, which usually has a small microcontroller translating, if you got a bad one and it fried your board, i would contact the company
If there was a rotten cap in the mix it could have just drawn enough extra current to push it over from rotten to dead

That's kind of what I was worried about. I don't want to throw stones at this company, knowing full well that some bad caps might be the issue. The Mac *was* working perfectly before attaching their adapter, but if bad caps are the culprit, I'd hate to accuse them of something that's not their fault.If there was a rotten cap in the mix it could have just drawn enough extra current to push it over from rotten to dead
I did the same thing to my Mac LC over a year ago, except that I just hot-plugged an ordinary ADB mouse or keyboard because I was in a hurry.now my ADB ports don't seem to work at all, except for the power button on the keyboard. The Mac boots normally, but the keyboard and mouse aren't responsive. They both work fine with my IIci, so I know it's not the keyboard and mouse itself.
Well guess what? I paid for it by destroying the ADB port. It is dead.
As a guy who gets those phone calls for a company, all i can say is "stuff happens" , call them up or email them, be nice explain what happened (omit that your computer could have electronics issues) and see what they sayThat's kind of what I was worried about. I don't want to throw stones at this company
If they turn out to be "not my problem" a-holes then we can throw stones
I sorta remember a fuse on the ADB port 5V line. Don't have a II cx to look at, but have a squint at the mobo for a little surface mount chip labelled F-something. There is also a fuse on the SCSI port for termination power. If you're into quick & dirty, a single strand of copper from some stranded wire will get the current flowing again.
