'''APC-H412''' here confusingly refers to a number of full-size NEC keyboards whose model numbers begin "APC-H41", followed by additional characters.

== Description ==
Examples to date have been found to use [[NEC_ovals|NEC blue oval switches]] and double-shot keycaps. The layout is ISO or ANSI, with one modification: there are no spaces between the control and alt keys.

Weights are attached to each side of the mounting plate.

==Variants==
===APC-H4120===
ANSI version; appears to be from ca. 1989. The legends are an unusually pale shade of grey.
