Just in case anyone wants to know, the sound board has the following
info printed PROMINANTLY on it "VECTORBEAM (C) 1978" and just below
"80-3001 C", then a hand printed code, this one is Sn084-051. There is a
7406, TLI82, and 5 TL081CP's. One adjustment pot and a nine-pin
power/speaker connector on the sound board.

The barrier that I am shipping (soon) has a 15 pin connector on the
power supply, but only the first nine (9) pins are actually used...

Just for the curious..
