Its not a virus. Trust me. I have a big box of disks that I use including install disks, Workbench disks etc and these disks get swapped out on other machines. I've been using the same disks on a 600 this morning and she installed and ran fine. Same again with another 600. Its not a virus.
The mouse only works on none Workbench windows. I can play Lemmings on the mouse no problem. I can play any number of games that need mouse and keyboard and joystick no problem. My little application for testing the ports lets me click as many times as I like. But when I close that window and try to click the icon it refuses to click and then the mouse freezes.
If I boot from an external floppy drive I get a lot longer with the mouse, but only a matter of ten seconds. It isn'the movement of the mouse and I can also hover over icons. The joystick is woring without fault, but that isn't clicking icons. Also as I said the ALT-LA or ALT-RA doesn't click an icon if the process has halted.
There is an issue with one of the chips and its busted. Everything is surface mounted and I am not an electrical engineer. I have no skills at all. Best I can do is go through the motions and check the processes and see patterns of behaviour. I use the same disks on another 600, doing exactly the same and I get no problems. I have tried two other 600s and have not been able to replicate the problem.
This computer has a dodgy floppy drive. It will only boot with the disk inserted. So if you try to boot by inserting at the initial boot screen it refuses to recognise the disk. However, the external drive works with no problem. I will have a look at the drive. The hardware isn't kicking the drive out, it's not working properly. Its not related to keyboard cus I booted without the keyboard attached and that just threw up the same problem. Like I said I even changed the ROM. Also swinging around my head with the power cord and smashing into the wall didn't help, but it made me feel better.
I had to give up with the computer cus to add more pain to my problems, I removed the cable from the interface for the hard drive and three pins came out. Totally random, not at the ends just three from the middle. I just couldn't believe my bad luck. The A600 is mothballed and labelled busted. So I'm not troubling myself with it anymore. I have to say the 600 is the worst Amiga ever made. Give me a 500 Plus any day. I can diagnose and swap chips no problem. This thing would be working by now. And I still think its the graphics chip or something to do with timing signals from that area of the machine. Could be the CIA maybe but the lack of failure within windowed applications and games, plus no other associated problems makes me reflect on issues I have had with the Denise in the past on the Plus.
Never mind... I have others so its no biggy. Its all getting a little too old, long past its sell by date in truth. I had my moneys worth. Ar hum.
