The caps lock switch on this keyboard is not locking like on previous TeleVideo Terminals. But rather linear with a LED to indicate when caps lock is turned on.
The layout is unique to this keyboard where the big ass enter with a 1.75u backspace key. Additionally, the numberpad consists of some other special keys like the double 00 key and CE key.
The switch plate is made out of stamped steel. The switch plate is then painted in a black paint and coated to prevent rust.
The PCB is single sided with all traces on the back side of the PCB.
The is made from a single piece of ABS plastic with an indent where the OEM can put the badge that is for the customer of the keyboard.
The lowercase contains hard bumpons and fold away feet that when folded away are recessed into the bottom of the lowercase.
