SAA3010
The device can generate 2048 different commands and
utilizes a keyboard with a single pole switch for each key.
The commands are arranged so that 32 systems can be
addressed, each system containing 64 different
commands. The keyboard interconnection is illustrated by
Fig.3.
The circuit response to legal (one key pressed at a time)
and illegal (more than one key pressed at a time) keyboard
operation is specified in the section “Keyboard operation”.
