The PCB-transformer key design is novel, but (in the TS-1) so is the scanning &
communication.
There is no microcontroller on the keyboard, scanning is performed by the main unit, it
sends a key matrix address to the keyboard in serial, the keyboard sends back nothing but
a binary key-pressed indication.
I'm not positive, but my impression is that the same is true for the VT-100 keyboard.
