The C1502A was an internal DAT drive for HP 3000/900 and 9000/800 series computers. The C1502A came with a SCSI interface. The C1501A was mechanically identical to the C1502A, but it came with an HP-IB interface. These drive mechanisms were found in the stand-alone C1511A and C1512A external drives.

Collector's Notes:

The C1501A and C1502A are identical except for the interface board at the rear of the mechanism (C1501-66002 for HP-IB and C1500-66001 for SCSI).

These old DDS drives are becoming increasingly unreliable. Of the six units we have at the museum, only one will eject a tape properly. Two of our units also have defective mechanisms. They both give the signal of a solid yellow LED on the bottom and single flashing yellow LED on the top.

Be patient with these old drives. The manual says that a tape will eject ten seconds after pushing the button. But, it can take two minutes or more. And, the drives will make clicking noises as part of normal operations.

If you get a tape stuck in one of these drives, DON'T try to force it out. You risk breaking one of the gear wheels; then the thing will never work. You can manually eject tapes from these drives. On the left side of the drive (while looking at the front of the mechanism), you will find a small (approximately 2cm x 2cm) plastic cover that is glued to the metallic frame. Remove this cover and you will see a small cogged wheel. You can get the tape to eject by rolling this wheel downward.
