[GreenKeys] Keyboard lock

[Frank Carraro]

I have a 28 printer that was extensively modified.  It was converted to an 82b2 type system. As such the keyboard was not needed so the kbd unlock key was disconnected.  Pressing that key operates the lever that passes through the comb, but that’s all. How can I unlock the kbd?    I am fairly familiar with the 28 Typer but never dug into all of the kbd
