Hi. I replaced 5 RAM chips on my original 128k motherboard. I successfully desoldered the faulty chips, soldered in new ones, and no more sad Mac! It now boots from a floppy and gets to the desktop. However, moving the mouse does NOT move the cursor on the screen. I tried 2 different mice, both of which work fine on my Mac Plus. The mouse button DOES work- I can click and see the Apple menu (because the cursor starts there), but can’t get the cursor to move. I don’t even know where to begin to look to try to repair this.
Anybody have any ideas? Again- it’s not the mouse, but something in the computer.
Thanks!
