ɹ 1. Internal DAC
The internal OPL3 and the ZV Port shares the internal DAC, which is very similar to the case
mentioned the previous section.
(i) either internal OPL3 or ZV port is active at a time and simultaneous use is not
possible.
(ii) which function the internal DAC is used for is determined by the SA3 control
register, index 02h, VZE bit.
ɹ 2. OPL4-ML/ML2
The external DAC (YAC516) and the clock module (ex.MK1420 by Micro Clock) are
necessary for wave table upgrade.
