Focus FK-727

The Focus FK-727 was one of Focus's first keyboards and was likely their first AT layout keyboard.
So far, it has only been documented to have been rebranded by Northgate Computer Systems¹⁾
It uses a DIN-5 cable and could come with two different types of switches: Alps SKCM Blue and Omron B3G-S Cyan ²⁾

The keyboard consists of three parts. A top case, a bottom case and a internal assembly.

The top is ABS plastic and uses a sloped design similar to many AT layout keyboards of the time.
Externally, it has a long sticker above the top row with blocks for writing F key functions and transparent windows for the lock-light bank.
Internally, it has a PCB for the lock-lights, a Focus Logo in the top left corner and standoffs for the case and assembly. The case standoffs are plastic and the assembly standoffs use brass inserts.

The back is made of painted steel.
Externally, it has an AT/XT switch and four feet in total: two non-slip feet and two flip-out feet with hooks for routing the DIN-5 cable. The back also has a S/N sticker, a QC sticker and a country of origin stamped into the bottom-right corner.
Internally, it has the AT/XT switch PCB and a grounding point for the DIN-5 cable.

The keycaps are Focus's early Alps mount OEM profile ABS pad-prints. Rather uniquely, the spacebars on these early Alps mount Focus keycaps use clone Cherry MX stabilzers.
