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:
