This keyboard was OEMed for NCD. NCD N-97SYS keyboard is another version of the NCD N-97 but this keyboard contains an additional silkscreen that contains the words "Security Keyboard". The N-97SYS seems to be an internal keyboard that was produced later on during the production run as the model sticker on the back is a replacement on top of the original model number.
This keyboard was produced for NCD17c terminal.
The keyboard’s layout is unique to this keyboard and NCD:
The keycaps are made out of PBT with dye-sublimated legends. These keycaps are unique to this keyboard as they use a different font and unique colorway.
The upper case is made out of a single piece of beige ABS plastic. The plastic is textured due to the molding process that is used to create the upper case. The lock lights in the upper case are unique to versions of the N-97. This version contains a silkscreen bar across the top of the case where the "SECURITY KEYBOARD" is cut out to reveal the case color in order to create the lettering.
The case is made out of a single piece of beige ABS plastic. The plastic is textured due to the molding process that is used to create the lower case. The lower case feet are super flimsy and feel like they are going to break when moved from the retracted to the out position.
The switch plate is made out of stamped steel. The plate is bent on either so that it can be mounted to the lower case. The plate is painted with a thin layer of black paint. The paint is then protected by a thin layer of oil to prevent rust.
The PCB is a double-sided PCB with all traces on the backside of the PCB. The controllers found on the PCB are Motorola.
The cable is a long coiled cable about 30cm long when fully stretched. The cable terminates on one end with a PS2 connector and the other end with a 6 pin molex connector.
