TVI-Kbd-converter

This is an arduino project to convert a PS/2 interface keyboard to attach to a TeleVideo terminal. It is verified to work with a 965, and should work with other terminals such as the 970, and TS-803 computer with no change.

With just a baud rate change to 1200 baud, it might also work with 925/950 based terminals with a 4-pin modular keyboard. Note that these all use 12V power to the keyboard, so they should not be directly connected to the VCC pin.

This uses the PS2Keyboard Arduino library, so download and add that to the IDE first: http://www.pjrc.com/teensy/td_libs_PS2Keyboard.html https://github.com/PaulStoffregen/PS2Keyboard

See the schematic in TVI-Kbd-converter.sch / .png below.

Note that this requires a straight-through modular cable to connect to the terminal, where most phone cables are cross over (they swap pin directions on each end). So you may need to crimp your own cable for this to work.
