This keyboard is a clone of the [[IBM 3270|IBM 3270 Emulator]] and connects to PCs using either the [[PS/2]] or the [[AT]] protocol. It comes with 4 extra keys which send a NULL before the key codes of 1 2 3 and 4 which means that these keys are useless on computers using the PS/2 protocol. With the IBM 3270 it shares the same style of labeling, for both the connecting PC and the mainframe computer it connects to. Keycaps are double-shot and pad-printed.

==Features==
The black legends are mostly double-shot (except for the LED window keys). All blue legends are pad-printed and clear-coated. This keyboard is not programmable. It is possible to use it with either AT or PS/2. Also, this keyboard lacks any functionality of [[n-key rollover]].
