Description
Like the F1, the F2 and F10 had an infra-red interface for the keyboard and the mouse/trackball (the same infra-red mouseball pointing device used with the Apricot Portable). This interesting feature was not very convenient because you had to ensure that there was no object blocking the signals between the keyboard/mouse and the computer, and you also had to power the keyboard with batteries! However, the systems originally shipped with a plastic light-pipe that could be connected between the keyboard and CPU so that obstacles would not block the signal.
