The Datamaster is an all-in-one computer with text-mode CRT display, keyboard, processor, memory, and two 8-inch floppy disk drives in one cabinet. The processor is an 8-bit Intel 8085, with bank switching to manage 256 kB of memory. The intention of the Datamaster was to provide a computer that could be installed and operated without specialists.
A BASIC interpreter is built-in; merging its BASIC with the one for the System/34 reportedly delayed the Datamaster by almost a year. When introduced, a single-screen Datamaster sold for around US$9,000 (equivalent to $24,266 in 2017)). A second keyboard and screen could be attached in an extended configuration.
The familiarity of the design group gained on the Datamaster project encouraged selection of an Intel CPU for the IBM PC, announced one month after the Datamaster. The delay from the BASIC encouraged IBM's selection of Microsoft BASIC for the PC.
