It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971. Unlike a modern personal computer, the Kenbak-1 was built of small-scale integrated circuits, and did not use a microprocessor. The system first sold for US$750. Only 44 machines were ever sold, though it's said 50 to 52 were built.
The Macintosh was the first successful mass-market all-in-one desktop personal computer with a graphical user interface, built-in screen, and mouse. [33] It was first demonstrated by Steve Jobs in the first of his famous Mac keynote speeches, and though the Mac garnered an immediate, enthusiastic following, some labelled it a mere "toy". [34]
First built in 1972, a small number shipped in early 1973.

TV indicates the factory configuration produces composite video compatible with a home TV receiver. Some computers came with a built-in RF modulator to allow connection to the TV receiver antenna terminals; others output composite video for use with a free-standing monitor or external RF modulator. Still others had built-in or proprietary monitors.
This "peripherals sold separately" approach is another defining characteristic of the home computer era. A first-time computer buyer who brought a base C-64 system home and hooked it up to their TV would find they needed to buy a disk drive (the Commodore 1541 was the only fully-compatible model) or Datasette before they could make use of it as ...
The Hewlett-Packard 9100A (HP 9100A) is an early programmable calculator [3] (or computer), first appearing in 1968. HP called it a desktop calculator because, as Bill Hewlett said, "If we had called it a computer, it would have been rejected by our customers' computer gurus because it didn't look like an IBM. We therefore decided to call it a ...
Dell Inspiron One 23 Touch as an example of an AIO desktop PC. An all-in-one (AIO) desktop computer integrates the system's internal components into the same case as the display, thus occupying a smaller footprint (with fewer cables) than desktops that incorporate a tower. [47] The All-in-one systems are rarely labeled as desktop computers.
[6] [7] The first machines were introduced on March 1, 1973, [8] and in limited production starting one decade before Xerox's designs inspired Apple to release the first mass-market GUI computers. The Alto is contained in a relatively small cabinet and uses a custom central processing unit (CPU) built from multiple SSI and MSI integrated circuits .
