From little Acorn Electrons, addons have been noticeably slow to grow. First Byte Computers (0335 43729) has now taken its place among the early leaders in adding to the Electron a switched joystick interface.

Its unit takes Atari-type joysticks and it has been talking to software houses to make sure that when the box comes out at the end of this month there will be games to play with it.

The FBC interface will cost £24.95 from FBC's dealer.
