IBM Corp yesterday previewed the IBM PCradio, an 80C186-based hand-held rugged MS-DOS personal computer that extends host services to the mobile workforce via a variety of communication alternatives. The machine was only previewed because it does not yet have Federal Communications Commission approval, so cannot yet be sold, although IBM hopes to have all the red tape sorted out in time for fourth quarter deliveries. It has a 5MHz to 10MHz 80C186 with power management system, integrated circuit memory card slot, Colour Graphics Adaptor liquid crystal diode display, QWERTY keyboard with embedded numeric keypad, 2,400bps internal modem, RJ11 interface, battery charger and serial and parallel ports for attaching external devices. There will be versions for radio, cellular or fixed telephone line – PCradio Models 001, 002 and 003 – and it will be available on a special-bid basis. It operates at up to 2,400bps over phone lines, up to 4,800bps by radio, and also supports speech communication over cellular networks when the optional handset is used. There is also an optional, integrated 40 character thermal printer and a facsimile send-receive capability over cellular or land line at up to 9,600bps. Applications can be stored on memory cards.It measures 10.5 by 8.4 by 2.5, weighs between 5 lbs and 6 lbs operates normally at 95% non-condensing humidity at 40oC for eight hours as well as meeting the requirements per MIL STD 810D, Method 506.2, Procedure II – Drip for exposure to rain. Special bid means you have to haggle with IBM on price.
