The steam-powered automatic flute described by the Book of Ingenious Devices (850) by the Persian-Baghdadi Banū Mūsā brothers may have been the first programmable device. [10] Other early mechanical devices used to perform one or another type of calculations include the planisphere and other mechanical computing devices invented by Al-Biruni ...
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 ...
Three brothers who wrote the Book of Ingenious Devices, describing what appears to be the first programmable machine, an automatic flute player. [8] 1960–1964 Baran, Paul: One of two independent inventors of the concept of digital packet switching used in modern computer networking including the Internet.
The "brain" [computer] may one day come down to our level [of the common people] and help with our income-tax and book-keeping calculations. But this is speculation and there is no sign of it so far. — British newspaper The Star in a June 1949 news article about the EDSAC computer, long before the era of the personal computers.
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.

Arab astronomer, Abū Ishāq Ibrāhīm al-Zarqālī (Arzachel) of al-Andalus, invented the Equatorium [citation needed], a mechanical analog computer device used for finding the longitudes and positions of the Moon, Sun and planets without calculation, using a geometrical model to represent the celestial body's mean and anomalistic position.

Digital machinery used difference engines or relays before the invention of faster memory devices. The phrase computing machine gradually gave way, after the late 1940s, to just computer as the onset of electronic digital machinery became common. These computers were able to perform the calculations that were performed by the previous human clerks.
