/***************************************************************************
NAMCO sound driver.
This driver handles the four known types of NAMCO wavetable sounds:
- 3-voice mono (PROM-based design: Pac-Man, Pengo, Dig Dug, etc)
- 8-voice quadrophonic (Pole Position 1, Pole Position 2)
- 8-voice mono (custom 15XX: Mappy, Dig Dug 2, etc)
- 8-voice stereo (System 1)
The 15XX custom does not have a DAC of its own; instead, it streams
the 4-bit PROM data directly into the 99XX custom DAC. Most pre-99XX
(and pre-15XX) Namco games use a LS273 latch (cleared when sound is
disabled), a 4.7K/2.2K/1K/470 resistor-weighted DAC, and a 4066 and
second group of resistors (10K/22K/47K/100K) for volume control.
Pole Position does more complicated sound mixing: a 4051 multiplexes
wavetable sound with four signals derived from the 52XX and 54XX, the
selected signal is distributed to four volume control sections, and
finally the engine noise is mixed into all four channels. The later
CUS30 also uses the 99XX DAC, or two 99XX in the optional 16-channel
stereo configuration, but it uses no PROM and delivers its own samples.
The CUS30 has been decapped and verified to be a ULA.
