The Chicony KB-5181 is an XT/AT switchable keyboard from Chicony. It features a big-ass Enter key and single-unit backspace. There is also an ISO version, the KB-5182. Both keyboards were supplied with a wide variety of switches, including Monterey. Two-height flip-out feet are provided.


The official list of switch manufacturers according to Chicony, in order of production, is as follows:

Aristotle were the manufacturer of the Cherry MX clone switches found in these keyboards.

Possibly due to manufacturing crossover between the Chicony KB-5161 and its successor, the KB-5181, Futaba switches were still in use in the KB-5181, although Chicony have no record of this being the case. KB-5161 and KB-5181 keyboards appeared to have compatible parts.[1]
