'''Chicony KB-5161''' is a series of keyboards from [[Chicony]]. The details below are incomplete and potentially subject to errors.

==Re-Brands==
*Samsung / VTI ([[Alps SKCM Blue]])<ref name="VTI"/>

==Variants==
===KB-5161/5162===
Appears to be the 2-key rollover series.

;KB-5161C/5162C
:[[Alps SKCM Blue]] ("ALPS", 1987 PCB)<ref name="Sandy-5161C" />
;KB-5161F/5162F
:This code refers to at least two different keyboards:
:*[[Cherry MX Blue]]<ref name="Sandy-MX" /><ref name="KBT-ARC" /> and either [[alps.tw Type TWB 2B]] or [[alps.tw Type TWB 2B|3]] Cherry MX clone — both variants cite "CHERRY SW" on the PCB, thus not yielding the name of the clone manufacturer; as Chicony only cited [[Aristotle]] as their source of Cherry MX clones, it's possible that these switches are an earlier type of [[Aristotle Cherry MX clone]]
:*[[Alps SKCM White]] ("ALPS", 1989 PCB)<ref>Deskthority — [http://deskthority.net/photos-videos-f8/chicony-5161-t6835.html Chicony 5161]</ref>
