PROGRAMMABLE INTERFACE WINS PRAISE FOR PROTEK
THE NEW SWITCHABLE joystick interface for the Spectrum from Protek can make games playing very much easier. All that needs to be done is to plug it into the back of the Spectrum, connect a standard joystick and load the game. A switch at the back is used to select either Protek (cursor), Kempston or Sinclair -6, 7, 8, 9, 0 - keys and you can switch between them while the game is playing.
The interface is, as is all too common with add-ons, dead-ended, so it must be the last add-on fitted. As with the Turbo interface, it is liable to crash if used with a twin fire button joystick. Its main disadvantage is that in the Protek position the top row of keys is disabled while in the Sinclair position only the 6,7,8,9 and 0 keys are disabled, which could make some games difficult to play. The switch would have to be moved, the key pressed, and the switch returned to its original position.
Despite those difficulties, which should not affect most users, the interface is easy to use and covers nearly all of the games on the market. It costs £19.95 and Protek is at 1A, Young Square, Brucefield Industrial Park, Livingstone, West Lothian, Scotland.
