5 DEC VT100 keyboard emulation
6
7 All data to and from the keyboard is transmitted over a single
8 bidirectional wire. The clock that runs the keyboard's UART and
9 scan counters is multiplexed with the serial data signal.
10
11 MS7002 is a Soviet clone of the VT100 keyboard. It features a
12 bit-paired JCUKEN layout and Russian/Latin mode select keys, but
13 the codes it produces are mostly the same, as is the electrical
14 interface.
