"The Enterprise is a Zilog Z80 based home computer first released in 1985. There are two variants, the Enterprise 64 with 64 kB of RAM, and the Enterprise 128 with 128 kB. The machine was also known by the names DPC, Samurai, Oscar, Elan and Flan before the Enterprise name was finally chosen.
The machine has a Z80 CPU running at 4 MHz, 64 kB or 128 kB of RAM and 48 kB of ROM containing the EXOS operating system and BASIC. The case is unique for its time (in the UK at least) for containing both a full-sized membrane keyboard with programmable function keys, and a joystick.
The machine was specifically engineered for games, with a up to 672×256 pixel display and up to 256 colours per pixel (in 180x80 mode, one byte per pixel being particularly easy to program). Sound was 4 channels, stereo. A graphics coprocessor called "Nick" and sound coprocessor called "Dave" (named after the designers Nick Toop, who had previously worked on the Acorn Atom, and Dave Woodfield) takes the load off the central processor.
The machine came with a surprising array of connectors, far beyond what was common on home computers of the time. There is an RGB output, RS232/RS432 serial port, a Centronics printer port, two external joystick ports, a cassette interface, a ROM cartridge slot and an ordinary expansion port. (To save money, however, the connectors on the rear did not come with sockets. They simply exposed traces on the edge of the printed circuit board).
The BASIC ROM can even be replaced by a ROM which can emulate a ZX Spectrum, thus in theory allowing the Enterprise to run the existing catalogue of thousands of Spectrum games. Later, an external floppy drive became available, supporting CP/M programs." (Wikipedia)
