I posted this back on the 7th and did not get any responses, so I am again asking for some help. Would someone know where I could start to look to find the problem, thanks.
I was running it with a 1960 monitor, when the monitor shorted out. Now the A1200 has problems. I installed new 3.1 roms and after about 25 seconds the computer recognizes them and shows the load workbench screen and identifies the roms correctly. But I can not get the Boot screen to come up and the computer chews up any disk I insert in the internal drive. Starts finding block errors all over the place and with a game disk, will load the intro screen and nothing else. Of course all these disk load perfectly fine with no errors on my other A1200. So what got cooked?

Making a quick guess, I'd say the CIA chip that controls the floppy has been zapped. I think you can google some A1200 schematics to see which I'm refering to.

Hi! could be a cia chip or the Paula chip I tend to think it may be a cia chip as you cant get to the early boot screen sounds as if your mouse has stopped working ( cia related). I lost my mouse once on my 1000 and replaced the cia chip and it worked perfectly now the bad news the cia chips are not socketed on a 1200 and would probably have to be replaced by a techo unless your pretty good at soldering? try swapping the Paula first and see how you go you may be lucky.
