The Laser Battle/Lazarian sound board has a SN76477 CSG, two TMS3615
tone synthesisers, and a TDA1010 power amplifier. It receives
commands from the game board over a 16-bit unidirectional data bus.

The TMS3615 at 05 is clocked at 250kHz (4MHz crystal oscillator
divided by 16), and its divide-by-two output is used to clock the
TMS3615 at 04. This gives a base 16' note of C3. The combined 8'

switched between two octaves. There's no indication of which octave
would have been selected in the Lazarian manual.
There's a filter network between the TMS3615 outputs and the power
amplifier with several parameters controllable from the game board.

signal from before the output amplifier is taken and used to gate
distortion elements in the analog filter network.
