 HP DC100

The DC100 tape format and drive was developed by Hewlett-Packard and introduced as a data storage mechanism for the HP-9825 programmable calculator.The DC100 tape cartridge was a scaled-down version of the DC300 cartridge pioneered by 3M, and represents an early version of what is now referred to as the QIC Mini Cartridge

This format was used in the HP desktop calculator/computer systems of the late 1970s and early 1980s, including the 9815, 9825, 9845 and HP series 80.
