More on this type of keyboard...
The IBM 3101/7485 Display Terminal Keyboard was a low-profile replacement for the original Model B-based IBM 3101/7485 keyboard and was introduced in August 1984. The IBM 3101 ASCII Display Terminal was a serial-based terminal that used RS-232C and RS-422 for short and long-distance communication respectively. The 3101 was originally rolled out in October 1979 and was used with IBM System/1 minicomputers and IBM 8100 Information Systems. The IBM 7485 Display Station is believed to be a 3101-based terminal available under RPQ. The low-profile 3101/7485 keyboard is based on the IBM 3104/3178 Typewriter Keyboard (31XX-87 type Model F) which happens to already use essentially the same physical layout as the original 3101 keyboard and has a compartment useful for the 3101 keyboard's dip switch bank. Notably, the low-profile 3101/7485 keyboard lacks the 3104/3178 keyboard's characteristic blue-coloured switch used for toggling the terminal's display between mixed-case or uppercase-only characters, giving these their nickname "blue switchless" Model F. However, the 3101/7485 keyboard retains a solenoid.
