SE/30 laggy mouse


Recommended Posts

Hey all, so Ive noticed when Ive done certain actions like loading some headers in Think C 5 or playing civilization my mouse gets extremely laggy and slow to move. It looks like a slide show. I have 8mb of ram, is that maybe the issue? Also, even after closing either program the mouse still has the laggy symptom, even after a restart. If I unplug the SE/30 then power it back on it works fine. Thanks!

I sometimes have the problem with my mouse cable. It stays in a static position and then my mouse doesn't move as I want it to.

I have to jiggle the cable to get it back working. I suspect that something is wrong with the cable but I am not sure.

I would be very surprised if the RAM was the problem. What might be a problem is a small capacitor (or somesuch) on the motherboard but I reckon your ADB ports wouldn't work at all.

There is a little app called 'ADB Reset' that might help.

Some thoughts:

Does your mouse-ball/mouse need cleaning or a better surface to gain traction on?

Have you eliminated the ADB port as the source of the problem?

If the mouse is plugged into the keyboard, have you eliminated the keyboard cable and keyboard as the source of the problem?

For example, is the mouse equally erratic in both ADB ports? Or is it plugged into your keyboard? Do other ADB devices behave erratically in either or both of the ADB ports?

Yep, in fact I’m pretty sure the Sony driver disables (all?) interrupts during reads and writes to prevent it from getting interrupted mid-read/write as the disk spins under it, not just during initialization.
