Description

The Datacomp DFK-777 was one of Datacomp's AT keyboard models.
It often appears rebranded by computer companies such as Computerland and Ultra From Imagineering.1).
It's been documented to come with two different switches: SKCM Blue Alps and Futaba MA 2) and It features a AT/XT switch and DIN-5 cable.

Construction

Case and Internals

The keyboard consists of 3 parts: A top case, a bottom case and a internal assembly.

The top case externally features a sort of raised “ridge” around the alphanumeric block that turns into a slope around the top of the cluster and serves as a pen holder. The top right hasa locklight sticker.
Internally, it features standoffs for screws with brass screw inserts, standoffs for holding the case in place and the flip-out feet mechanism.

The bottom case is made out of a painted metal that can rust which implies it's made out of steel.
Externally, it features a cutout for the AT/XT switch, a sticker for said switch, a S/N sticker, a country of origin stamped in the bottom right and six total feet: four being non-slip feet and two flip-out feet for adjusting the keyboard's angle.
The Futaba variant features an extra sticker with the keyboard's FCC ID on it
Internally, it has a PCB for the AT/XT switch and a couple pieces of rubber and tape to prevent the assembly PCB from shorting.

The assembly consists of a PCB and painted metal switch plate. The switch plate can rust which implies it's made of steel.
On the back of the keyboard PCB there is a cable soldered to it that connects to the AT/XT switch PCB.

Keycaps

The keycaps are made of doubleshot ABS on both variants. The Futaba variant uses distinctive “tombstone” keycaps, and the Alps version uses regular Alps OEM profile keycaps.
