Introduction

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].

Description

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.

Switches

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.

Hua-Jie AK series for most keys^[1]; lock keys use Alps SKCL Yellow
Futaba clicky switch (Cherry MX mount) which in one instance at least have been found not to click^[3]; lock keys use Alps SKCL Yellow or Alps SKCL Green^[4]
White Alps.tw_Type_OA2 for most of the keyboard, Alps SKCL Yellow for lock switches.
