A&J Microdrive

A&J MicroDrive, a small external box maybe 6x2x4 inches, a single DB 25 connector with just 6 pins (looking in the open end of the connector; 2, 4, 5, 6, 7, and 20), nothing for power. On the front mine says System 100 and down in the left corner Active/Low Battery, right corner A. On the back; A&J Micro Drive 1050 East Duane Avenue, Suite I Sunnyvale, California 94086 Voice 408-732-9292 BBS 408-732-6464 Date 12-6-85 Serial NO. 010145 Four screws takes off the back, and reveals fortunately an empty and clean carrier for 4 AA batteries (only two appear used, and those in a +1.5 and -1.5v fashion), a simple looking circuit board, and a BSR tape mechanism. More good news, I saw no rubber parts in the tape drive, so my guess is find a good tape, and it still works. I didn't see anything like an ID on the tape drive, but it is a single gap head (two wires and a shield only go to it). The tape cartridge loads straight in the front, and the opening is about 2.5" x 3/8" with depth less than 2" (of course it could stick out). The only moving part is the VERY skinny (like a needle) drive pin on top of the motor near the left side. On the side of the left front and right rear there is a small metal "bump" spring to retain the tape, but no release or other movement in the drive.
