I can't find any information on this drive. This is the drive in question --


The SCSI ID (1-3) is perhaps obvious, but 4-6 are just labeled on the unit "Usually OFF". The remaining three are probably for parity and termination and something else. Sector size would be an obvious third candidate but I doubt a drive like this would have a select-able sector size.

I'm looking for this information, because this drive is incorporated into an external enclosure that has CD Audio transport controls as physical buttons that seem to be implemented with an additional SCSI IC within the unit that sends the playback commands to the drive. I want to replace this drive with something else and retain the use of the transport controls but I've been unsuccessful. If I knew what the 4-6 pins correspond to I might have more success.
