Hi gang. I have this Westinghouse W1642 terminal keyboard that I believe was used in the airline industry. It's a neat piece with a metal top and bottom and spherical keycaps. The connector looks like DB-25.
The switches look like Keytronic foam and foil, is that right?
Is the protocol an RS-232 connection, or likely something else?
Can't seem to find much info on these. I'm not sure it's of much use because the keycaps won't fit anything and it's missing some basic keys like 'Shift'.
Pictures below, thanks for any clues.
