128k mouse issues after RAM replacement

[sjbaird]

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!

SOLVED! Embarrassing, but this was just a software issue. I was using System software 4, and 128k Macs can only handle up to System software 3.2. My dumb mistake. Works great now.

You need to upgrade that turkey to a Fat Mac...

Better yet, upgrade to Plus ROMS, and then you'll have native support for HFS and System 6 (except for the drive, you'd then have essentially a 512ke).
