The Tektronix 4907 "File Manager" is a GPIB-compatible mass storage device for the 4051/4052 computer series (with File Manager ROM pack 020-0279-00).
The 4907 was available with one, two or three 8" double density single-sided floppy drives that require hard-sectored diskettes and provide up to 630,000 byte capacity per disc.
It uses Shugart SA800/SA801 drives with line-voltage synchronous AC drive motors, meaning that a unit configured for 60 Hz line voltage requires changing the pulley and belt in the disc drives to run on 50 Hz, and vice versa.
Options
- Option 30 - Two drives
- Option 31 - Three drives
- 4907F32 field update kit adds a third drive to a 4907 Opt.30
