Commodore 1541 Up In Lights
I have a Commodore 64 and a 1541 disk drive. This system worked perfectly for several months, but recently, whenever I turn on the 1541, both lights-the red and the green-come on and stay on. The motor starts spinning, and the drive accepts no commands from the 64. The only way out is to turn off the drive. What can I do?

The problem could lie with either your 64 or 1541. The best solution is to consult a service technician, but you might want to try some simple troubleshooting first. Hook up the 64 to a different 1541 if you can, and see if the problem persists. If so, the fault probably lies in the computer's operating system-it may-not be initializing the disk drive properly. If the other drive works fine, you can assume your own drive is defective.
    In this case, your problem is probably in the Read Only Memory of the 1541. You'll have to deliver the drive to Commodore or an authorized service center.
