After a week or so of obscure problems, my system died. Any suggestions would be most welcome. Obscure Problems. Some games would lock up and hitting reset blanked the screen while the button was pressed but the screen would be unchanged when the button was released. The programs may have locked up at a point when they were trying to access the sound generator. The system would not boot from some disks. One disk would fail at any one of three points but usually passed the RAM check program in the auto folder. System Death. I boot the system and the floppy select light does not turn on and the floppy does not spin. I've tried two different floppy drives and there is no change. Nigel

1226.1 | 1st guess, DMA controller | PRNSYS::LOMICKAJ | Jeffrey A. Lomicka | Mon Dec 30 1991 21:31 | 16 |
Does it eventually come up with a green screen and title bar? If so, or even if it doesn't, the first thing I'd suspect in your case is the Atari DMA controller. You should be able to get one in your neighberhood from Best Electronics. It's socketed (40 pin) in machines of your vintage, so the check is as easy as swapping the part with a friend. The second choice would be memory, but you didn't mention "vertical lines on the screen" in any of the failure modes, and vertical lines or bars are classic "bad memory" symptoms. Sometimes weird problems can be traced to bad power, but that usually comes with screens that jump when the floppy motor spins. So, go for the DMA controller, see what happens. | |||||
