TA7630P
Toshiba Dual. Volume / Balance / Tone (Bass/Treble)
A set of discrete filters that applies to sound chip outputs.
According to the datasheet, two channels are outputted from here after it applies
all of the filters
TODO:
- mostly a placeholder, needs a way to read from sound chips and output
back with filters enabled;
- filters balance/bass/treble;

background, and the gradient can move around (the latter doesn't seem to
be used except for making it cover the whole screen on the title screen,
and start at the middle during gameplay)
Update: stage 2 is supposed to have a different gradient, how/where
this is located is unknown (pen 0x20?)
- Video driver is largely unoptimized
- Support for the 7630's controlling the sound chip outputs (bass/treble,
volume) is completely missing.
- The sound Z80 seems to write answers for the main Z80, but the latter doesn't
seem to read them.
- videoram and spriteram garbage occurs when entering into cross hatch test and exiting.
Game attempts to transfer content of videoram into spriteram/scrollram, then transfer
back again into videoram. Maybe the host CPU cannot read contents of VRAM at all?
Notes:
- There is also a 4-channel version of the sound board for the cockpit
