Amlyn Minipac diskette changer

From: Steven Hirsch <snhirsch at gmail.com> Subject: Amlyn Minipac diskette changer Has anyone else on the list seen one of these? I picked up a Vista V1200 disk system for Apple 2 that uses this type of drive. The mechanism takes a plastic cartridge with five 5.25" floppy disks. The diskettes appear to be conventional SS format with a couple of extra punchouts to mate with the loader mechanism. Electrical interface is compatible with 8" floppy drives (interface card was also sold for that purpose). I'm not able to turn up any information about the drive and am wondering how the diskette select/load scheme is intended to work. There are at least a couple of possibilities: - Treat the physical diskettes as portions of a single logical floppy and select diskette by track range (first diskette 0-39, second 40-79, etc.) - Treat each physical diskette as a logical drive and use binary select lines on interface to choose. Anyone have documentation on the drive mechanism or the Vista product?
