The MZ-731 was launched in Japan in October 1982, but did not appear in the U.K. until October 1983. lt was the first Sharp home Computer with colour, but it came without a built-in display unit; instead, sockets were provided for a colour TV or an RGB Monitor; or a B/W TV set or a Mono Monitor. lt also had a built-in printer I/F with a switch which allowed you to run the MZ-1P01 4-pen plotter-printer or a more standard MZ-80P5( K ) dot-matrix printer.Thus, with its clock speed of 3.5MHz, the MZ-700 seemed to meet many of the criticisms levelled at the MZ-80A when it was launched in June 1982. But it was still only a halfway-house - the printer I/F only suited Sharp printers, the screen was only 40 columns, and to run disk drives you needed an extra interface of some kind.The MZ-700 was reviewed in the PCW Magazine in February 1984.
