The '''Focus FK-5001''' was the flagship of the [[:Category:Focus keyboards|Focus keyboards]] family. It featured a computer-independent built-in desktop calculator and [[function keys|programmable function]] (PF) keys.

==Design==
The design is similar to the [[Focus FK-3001]], with several differences:

*Standard [[function keys]] arranged into groups of three instead of four
*In addition to the standard F1–F12 along the top, the keyboard also provides F1–F10 along the left in the [[IBM Model F]] layout, plus a final F11 and F12 above
*[[Cursor keys]] for all eight directions (N through NW) surrounding a Turbo button
*The horizontal ridges running across the keyboard above the function keys were removed as of this model

==Features==
The built-in desk calculator with LCD is independent of the computer and is powered by a separate button cell battery. One or two keys above the [[numeric keypad]] switch between the numeric keypad and calculator functionality. The additional calculator keys do not generate scan codes, preventing them from driving a software calculator on the attached computer.

The [[typematic|key repeat]] rate can be set using the "Turbo" key in combination with the [[function keys]], e.g. Turbo+F1 sets it to 2 characters/second and Turbo+F12 gives 130 characters/second.

As usual, the [[DIP switch]]es are underneath the logo plate (top left on the front cover).

==Variants==
===Variant A===
As pictured below: LED panel at the top right; the numeric keypad is switched between input and calculator modes by way of two keys, labelled "KB Lock" and "CAL Lock".

===Variant B===
[[Lock key]] indication is given by red integrated LEDs within [[Alps SKCL Yellow]] switches. A single [[Futaba lock]] switch, labelled "KB CAL" toggles calculator input mode; the top row of calculator keys uses 1.25-[[unit]] keycaps.<ref>Deskthority — [http://deskthority.net/keyboards-f2/question-on-focus-5001-9000-keyboards-t5734.html question on Focus 5001/9000 keyboards]</ref>

==Switches==
*[[Alps SKCM White]] for most keys
*[[Alps SKCL Yellow]], for the LED keys
*[[Futaba lock]] switches in the boards with a single calculator toggle key
