DescriptionDysan Verbatim 5.25 disks 1978.jpg |
English: The diskettes for the Shugart SA-400 Minifloppy were jointly developed by Dysan Corporation and Information Terminals Corporation. Storage capacity of the minifloppy diskettes were 109.4 kilobytes unformatted and 89.6 kilobytes formatted. When the diskettes were introduced in August 1976 they only supported 35 data tracks, this was increased to 40 data tracks in 1977.
The software on these disks was developed by Technical System Consultants of West Lafayette, Indiana for Southwest Technical Products Corporation of San Antonio, Texas. It was a disk operating system for the SWTPC 6800 Computer System that used a Motorola M6800 microprocessor. The claim of copyright is for the contents of the disk, not the hand-written labels. These provide a date the disks were first used. |
