This board has the DC/DC converter which supplies the DC
power necessary for each board, the overlay SYNC signal
separation circuit, the external SYNC signal selection circuit,
and the overlay power supply regulator circuit.
The circuit centering on the Q201 and Q202 is the overlay
SYNC signal separation circuit. The signal output from this
circuit and the external SYNC signal input from the CN703
on the CB-31 board are sent to the C201. The IC201 selects
the external SYNC signal according to the SW706 on the
CB-31 board. The Q203, Q204 and Q603 on the H board
compose the regulator of the overlay power supply.
