|Another naked A2000|
Here’s another A2000 off the ranks. This one booted from the hard drive and floppy drives okay but whenever the left mouse button was used it would stop responding to mouse clicks all together after a few clicks. I inspected the battery area and, you guessed it, the dreaded corrosion caused by battery leakage. Albeit minor, I felt the corrosion needed sorting. I lifted the CPU and a few of the socket pins came with it! So much for minor damage. I replaced the CPU socket and installed the CPU to find the mouse issue was still present.

When the left mouse button was used to select an icon, that was okay. When another icon was selected it may be okay but if I
did that a few times the mouse pointer would move okay but I could no longer select with the left button, nor could I select
with the right button. Time to reboot – I did a lot of rebooting whilst testing these theories. I rebooted to hard drive, floppy drive with WB2.1 and WB1.3 and the problem remained. I also used the keyboard to control the mouse pointer with the same results. It seemed to me it had to be a hardware fault.
Upon rebooting I thought I’d use just the right button and it worked fine bringing up the menus in workbench. I right clicked and chose ‘execute command’ from the workbench menu and ran newshell and proceeded to run a heap of DOS commands with full success. I decided to try and run Directory Opus (DOpus)from the shell and it opened okay. The surprising thing was that I could use the left mouse button in DOpus until the cows came home. I backed out to workbench and within a few clicks, mouse clicks stopped responding. I also noted if I inserted a floppy disk into a drive, the icon for it would appear on the workbench. Deluxe Galaga ran fine for several games – Oh it’s such a hardship testing these computers. I always wondered why it took so long to get things done!
