Google gets it wrong. According to their 20 Year Usenet Timeline, the first post mentioning Macintosh and Lisa was made on August, 1982. In fact, the earliest post mentioning Maci…

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 …

You might be able to fix it, sounds like you blew up something on the data side of the ADB. I think if there was fusing it would only be for the power side but I don't have the sch…

That's kind of what I was worried about. I don't want to throw stones at this company Click to expand... As a guy who gets those phone calls for a company, all i can say is "st…

but if bad caps are the culprit, I'd hate to accuse them of something that's not their fault. Click to expand... Click to expand... Uhm, Caps don't have feelings. :lol:

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 w…

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 Click to expand... That's kind of what I was worried abou…

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 s…

Did you follow the instructions on that site? If you wanna go renegade, you can try soldering the mouse directly to the mobo? If you have like a dirty mouse or bad mouse of course…

I was afraid of that. The ADB-PS/2 adapter is for mice, specifically this: http://www.geethree.com/adb/index.html So ummm...anyone have another IIcx mobo with a socketed processo…

All the power button does is shorts two connectors. I doubt they make ps2-adb connectors,so you probly killed the mobo...

You sure that was an ADB-PS/2 adapter?

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 w…

Photo with some of the paint taken off. Click to expand... I know everyone is going to hate me for this but here goes. I like it. A lot. Get some rags and spray them with oth…

I got a decent amount of the paint off. A few more coats of it, and it should be gone. I'm pretty sure a normal soap/water scrub would work fine.

Some of us here collect KIM-1s, btw. Learned how to program it in high school with the hex keypad in 6502 assembly. Still have it. Works great. It's fun to have a computer that's a…

This wasn't getting the attention it deserved in another forum so I felt it appropriate to move it here. I am most interested in knowing about the MacSnap 5.0 "RAM upgrade" (witho…

Model 100's are awesome machines for what they're capable of. I have several here. A piece of lore behind the Model 100, btw, is that the Word Processing component of it is the l…

I have no idea what "dodgy C programmers" has to do with anything. Click to expand... With DMA, a dodgy C program can write into the data that something else is about to write …

The Mac II onwards were designed to use NuBus bus mastering for high speed data transfers. Both devices had to be on the NuBus, of course, and support bus mastering, at least as a …

Awesome! i loved those things. I used to have one. Try to find the floppy drive (and accompanying disk) that gives you 100KB floppy storage on a modern floppy. The floppy also ru…

As far as I know, the first Mac to actually have DMA (which the very first IBM PC had) was the IIfx and it was only used under A/UX. Click to expand... The Mac II onwards were …
