- Yes you could very well be having problems with the USD chip. It has two
- documented problems:
- 1- it runs hotter than the original Atari drive controller chip, make sure
- the drive has a continuous flow of air to it (i.e., don't put the drive
- under a shelf or something where the air doesn't move.
- 2- the chip legs are shorter than most IC's. Atari uses two socket types,
- one is flat and causes few problems (other than #1 above), and the other
- socket type has slight ridges. Due to the heat, if your USD is in one of
- the ridged sockets, it will work its way loose, and you will have to
- continually re-seat it. The easy solution is to buy a chip socket with a
- flat top, plug this into the soldered in socket, then plug in the USD. The
- cost is less than a buck.
-
- The above solved all my problems with my USD 1050.
