The Focus FK-8000 is an out-of-production standard (full) size keyboard by Focus Electronic. It has the same standard layout of the Focus FK-2001, but, in addition, it also integrates the calculator from the Focus FK-5001[1].


The keyboard is unbranded; the model number can only be found on the label on the bottom. The FK-8000 shares the same revised styling as the FK-5001. One of the selling points of the FK-8000 was the integrated, battery-operated calculator.

The calculator

The calculator toggle key—which switches between calculator and numeric keypad—is a Futaba lock switch.[1][2]. The integrated calculator is powered by a 3V battery. (The factory-supplied battery was a Hitachi Maxell CR2032.) The keyboard was shipped with a small round plastic insulator between the battery and its contact to preserve the charge before it was sold, or for long-term storage.


During its production years, the Focus FK-8000 featured a variety of switches under the same FCC ID, which is not that unusual but it makes it somewhat harder to catalog them all.
