Diskettes

Some of the earliest CRT-based machines used cassette tapes for removable-memory storage until floppy diskettes became available for this purpose - first the 8-inch floppy, then the 5¼-inch (drives by Shugart Associates and diskettes by Dysan ).

Diskettes use yet another "megabyte" equal to 1024×1000 bytes.

Grossman spent several weeks reducing files sizes and removing files such as the audio dialog to fit the game onto six diskettes.

In 1988 IBM introduced a drive for 2.88 MB "DSED" diskettes in its top-of-the-line PS/2 models, but this was a commercial failure.

It was shipped on five 360 KB diskettes of uncompressed files, and came with sample C programs, including a stripped down spreadsheet called mcalc.

One source claims that a special NCR 7200 model variant with two 8-inch diskettes and Microsoft BASIC existed and was imported by NCR Sydney into Australia the least.

The casing is thicker and more rigid than that of 3.5 inch diskettes, and designed to be mailed without any additional packaging.
