When we consider media for computers, one format that was in widespread use in the early years of personal computing but which fell out of favour entirely is the cassette tape.
Largely phased out of the market in favour of floppy disks, cassette tapes could store a reasonable amount of data but were, as anyone who has used them will tell you, a bit finicky and particular to work with on a day-to-day basis.
One of the most popular personal computers to make use of cassette tape storage was the Amstrad CPC 464, a machine built by Amstrad to compete with popular models from Sinclair and Commodore. An 8-bit computer that used tape cassette storage (but also included a floppy disk drive attachment), the CPC in CPC 464 stands for color personal computer and sold some 3 million units in the United Kingdom, Germany, France, Spain, and other areas of Europe.

The hardware would go on to become a mainstay of Amstrad’s lineup and spawned a series of successors that built upon the core unit and even a game console called the GX4000. The CPC 464 used a Zilog Z80A CPU with either 64 or 128 KB of RAM available in an all-in-one form factor that uses the keyboard as the computer’s body.
For storage, as we outlined above, the CPC 464 used either a tape deck or a floppy drive which, again, was built into the keyboard. Interestingly, the computer’s monitor serves as the powersource for the unit and came available in color as well as green and monochrome. Like many of its competitors, the Amstrad CPC 464 was a relatively low-cost machine that attempted to serve a variety of purposes including entertainment and even business applications. The success of the model line spawned a slew of compatible accessories as well as business
