Four inches of cable may not sound much for a piece of equipment that calls iteself an extension but the Kempston Extender Cable could make all the difference to Spectrum Plus owners. "We mainly brought it out for people with a Plus to use the single joystick interface," Kempston says. The cable includes a replaceable edge card and should reduce wear and tear on the machine's edge connector. It is also sutiable for the ordinary Spectrum, and 'ideal' for add-on keyboards, according to Kempston (0234-852997). It costs £7.94.
