3.4 Centaur Speech Commands

Information provided by PinSider "Quench".

The following is the list of the sound commands (in binary and hexadecimal) sent to the S&T board that produce speech. Communications between the MPU board and the S&T board are 4 bits wide. Commands are sent as two binary nibbles; lower nibble first then upper nibble.

The sound board test button plays these speech phrases in backwards order:

0011 0000 .. 30 -- "2X completed"
0011 0001 .. 31 -- "3X completed"
