This keyboard is a clone of the IBM 3270 Emulator and connects to PCs using either the PS/2 or the AT protocol. With the IBM 3270 it shares the same style of labeleing, for both the connecting PC and the mainframe computer it connects. Keycaps are doubleshot 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.
Although under the 4 removable blindcaps there are 4 key mounts and PCB traces, closing the contacts does not cause the controller to send any key codes. This might be due to controller programming (see also sister-model Cherry G80-2551).
