My new Atari 800 finally arrived! Jeez, this thing is huge. The 810 drive it came with doesn't seem to work, though... Never stops being "busy", just spins constantly, not reading anything at all. No idea what's wrong with it.
Yes Bryan, it always runs, even when it's not connected to the computer. I might try checking if any of the capacitors are bad. Beyond that, I don't really know what else can be done.
