Anybody having some input on this would be greatly appreciated. I've nearly completed updating and restoring our A500 to full operation. I did a Chip RAM upgrade by adding x4 DIP sockets and chips, modified JP2 and JP7A, replaced the floppy drive.
But I'm noticing an occasional glitch with the mouse sometimes. Every so often it will hang in place on the screen when I'm trying to move the cursor, usually when moving down or to the right. It seems to be momentary, then corrects itself. But it is very noticeable playing Marble Madness, as the marble goes off in the wrong direction suddenly.
I tested the phenomenon happening on both ports, and with 2 different mice - one optical and one ball driven. It's hard to tell if this is occurring with the joystick very much.
Capacitors wearing out? Did the memory modification interfere with something? I ran a few memtests and the new memory showed no errors. This isn't the worst, but any ideas?
