    The Enterprise is a Zilog Z80 based home computer
    first released in 1985.
    There were 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 had 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 was unique for the 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 672×256 pixel
    display and 256 colours per pixel (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)
    took 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 was 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 could even be replaced by a ROM which
    could 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.

    Commercial failure
    Despite being particularly powerful for the time, the machine
    was not a commercial success. The Amstrad CPC 464 was
    released before the Enterprise, was less powerful, but
    included a monitor and cassette recorder, and retailed for
    less. The CPC in fact had a strikingly similar colour
    scheme to the Enterprise, and it may be that
    Amstrad boss Alan Sugar
    had seen a prototype.

    After the initial manufacturing run of 80,000 units it
    is not believed that any further units were made, making
    the Enterprise an extraordinarily collectible item in
    Europe. When Enterprise (the company) was wound up in
    Europe, 20,000 units were shipped to Hungary where it
    appears a strong user community formed.

    Development
    After the home computer market in the UK
    took off with the launch of the ZX Spectrum
    a Hong Kong trading company called
    Locumals decided to commission Intelligent Software
    in the UK to develop a home
    computer. The head of Intelligent Software
    was David Levy, an
    international chess player.

    During development the machine had the codename
    DPC, standing for Damp Proof Course. The
    idea was to throw off potential competitors. This
    worked to an extent - at one point during development
    the plans were left on a bus.

    Emulating Amstrad's AMSOFT, Entersoft
    was set up to ensure a steady supply of software for the
    new machine.

    Although the machine was announced to the press
    in September 1983, it did not go on sale
    until April 1984, at which point some 80,000
    machines were pre-ordered. Unfortunately machines
    did not ship until 1985, by which point the
    competitive environment was much worse for
    Enterprise.

    A successor machine, the PW360, was developed
    in 1986 to compete directly against the
    Amstrad PCW 8256, but by this time the company
    was in severe financial difficulties and went under.
