M0100 Mouse & M0110 Keyboard Problems
Posted by: reodraca on 2025-05-28 18:27:37
I just acquired a Mac 128k today, complete with original keyboard and mouse. The Mac works great, but the keyboard has an issue where single types don't generate characters, pressing and holding works half the time but generates too many characters, and capital letters barely work. The mouse moves the pointer, but clicking does not work. My Mac Plus mouse works fine on the Mac, so I ruled out the Mac's mouse port being the isuse. How would I go about getting these problems fixed, or should I begin looking for a new original keyboard and mouse set?

Have you tried the Plus keyboard on the 128k? Do all the keys on the 128k behave the same?

I have never had one of those mice apart, but I would start by putting some deoxit into the switch contacts and see if that fixes the mouse.

Definitely don't start looking for replacements yet.

Keyboard ended up being bad. Liquid damage, corroded traces and rusted switches. Mouse switch is physically busted internally, which is why it wasn't working. Replacements work great, so thankfully not the logic board. Thanks for the suggestions.
