So i recently picked up a adb mouse and keyboard from ebay, and the keyboard works great, but the mouse c and y movement didint work. So i dissasembled it and it had severe curosion on the little sensors that track the movemnt. Are there any modern replacements for these? I know the mouse works as the click does click in MacOs. Thank you in advance, ill upload a picture of the little pcb in the mouse. Would be really nice if i could repair this mouse without buying another one…

Look interesting, but its quite expensive. Plus shipping to Europe, oh i forgot to mention that. Still looks pretty cool as its supposed to work on compact macs?

I use it on a IIgs with ADB, but it will work on anything with ADB. I don't think the person makes too many of them, thus the higher price. I have to say it does work pretty well and it isn't frustrating like the warn out roller ball.

I would really like to get the ball mouse working, as i have never used those. Im currently searching for 4 pin infrared receivers that could be used in ball mice.
