The KPT-84 has seen multiple switches and languages over its lifetime. In most instances the case is black, but white KPT-84 keyboards were also made.
The keyboard lacks a num lock key; the first LED indicates power instead. Some keyboards have the Power LED legend replaced with the KPT logo.
The variants with blue KPT switches are equipped with a non-clicky enter key.[Citation needed]

In Germany, the keyboard was sold by a company called GSE within their Creative Set, an add-on set for the GSE MPE-100S and MPE-200SX video cutting board containing headphones and the keyboard. Those sets are sold on eBay on a regular basis. The Creative Set was sold with different kind of keyboards. If you want to buy one, ask the seller to send a picture, as the keyboard depicted on the packaging (always the Marquardt Mini) does not necessarily match the actual keyboard included. There are versions with cheap rubber dome keyboards and seldom with the Marquardt Mini.
