The Coleco Adam is a home computer, an attempt in the early 1980s by American toy manufacturer Coleco to follow on the success of its ColecoVision game console. The Adam was not very successful, partly because of early production problems.
Coleco announced the Adam in June 1983 at the Summer Consumer Electronics Show (CES) and executives predicted sales of 500,000 by Christmas 1983. From the time of the computer's introduction to the time of its shipment, the price increased, from USD $525 to $725.
In its favor, the Adam had a large software library from the start. It was derived from and compatible with the ColecoVision's software and accessories, and, in addition, the popular CP/M operating system was available as an option. Its price gave a complete system: an 80 kB RAM computer, tape drive, letter-quality printer, and software including the Buck Rogers: Planet of Zoom video game. The IBM PCjr sold for $669 but included no peripherals, and although the popular Commodore 64 sold for around $200, its price was not much lower after the purchase of a printer, tape or disk drive, and software.
Like many home computers of its day, the Adam was intended to use a television set for its display. The SmartWriter electronic typewriter loaded when the system was turned on. In this mode, the system operated just like a typewriter, printing letters as soon as the user typed them. Pressing the Escape/WP key put SmartWriter into word processor mode, which functioned similarly to a modern word processor.
