The '''KPQ-E99YC''' is a standard PC keyboard manufactured by [[Mitsumi]], and used by brands including [[Commodore]] and [[Unisys]]. It makes use of [[Mitsumi KPQ Type]] switches incorporated into a curved switch plate and a curved backplate. Therefore, all keycaps have the same height [[Keyboard profile|profile]]. 

KPQ-E99YC was sold with no top branding, and Mitsumi's name on the rear label.<ref>RecycledGoods.com — [http://www.recycledgoods.com/mitsumi-kpq-e99yc-keyboard.html Mitsumi KPQ-E99YC Keyboard]</ref> It was also provided as an OEM keyboard to systems manufacturers.

==OEM versions==
===Commodore KPQ-E99YC===
US-ANSI version with Commodore part number 312702-02 has Commodore's "inverted" colour scheme, i.e. the alphanumerical keys have a darker shade of grey than the modifier keys as it is often seen on [[:Category:Commodore keyboards|Commodore keyboards]].

ISO versions have been spotted with Commodore P/N 312473-XX and these appear to follow the standard colour scheme. In addition, at least the ISO-ES (Spanish) variety has been found using an [[AT keyboard interface|AT/XT protocol switch]].<ref>{{volatile|Google Photos &mdash; [https://photos.app.goo.gl/HZ0TpSciHuSR0Plx1 Teclado Commodore]}} &mdash; photos of the Spanish version with the AT/XT switch on the back</ref><ref>{{volatile|Amibay &mdash; [http://www.amibay.com/showthread.php?96193-Commodore-PC-keyboard-like-new Commodore PC keyboard like new]}}</ref>
