Anyone knows why the Falcon has a 10 pin keyboard header on the PCB, but the keyboard has only 7 pin ?

The schematic shows Pin 9 KTOK and Pin 10 KROK, any idea what can be ?

A feature not exploited ?

Flow control for an unreleased Universal Keyboard Controller, see AF.

See the ST-BOOK Schematics ...

It is for a external Keyboard.

thank you
