This is a list of early microcomputers sold to hobbyists and developers. These microcomputers were often sold as " DIY " kits or pre-built machines in relatively small numbers in the mid-1970s. These systems were primarily used for teaching the use of microprocessors and supporting peripheral devices, and unlike home computers were rarely used ...
Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE. "Say" for EG, used to mean "for example". More obscure clue words of this variety include: "Model" for T, referring to the Model T.
Typically a home computer would generate audio tones to encode data, that could be stored on audio tape through a direct connection to the recorder. Re-loading the data required re-winding the tape. The home computer would contain some circuit such as a phase-locked loop to convert audio tones back into digital data. Since consumer cassette ...
The Aquarius manual did not contain details of any of the ports available.

The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
To save the cost of a dedicated monitor, the home computer would often connect through an RF modulator to the family TV set, which served as both video display and sound system. [17] The rise of the home computer also led to a fundamental shift during the early 1980s in where and how computers were purchased.
The category of early computers contains the computer systems made in the early era (i.e., the era in modern computer history defined as the period from the late 1930s to the early 1960s) utilizing mechanical, vacuum tube, discrete transistor, or other pre-integrated circuit technology.
