Sound board: uses the same board as Pooyan. Note: * The sound board uses a 14.318 MHz xtal. * The cpu/video board uses a 18.432 MHz xtal. Todo: * Discrete filters * Starfield Custom Chip 084 (Starfield generation) ---------------------- NE555 1Hz | 10 24 | VCC | | | | 18Mhz 401 | 1 19 | 419 Reset Enable 6MHz 109 | 2 | 256H* 403 | 3 Custom 084 | Vblank* 404 | 4 | /SYNC* 405 | 5 18 | Blue Aux.

The active one can be selected in Machine Configuration. a) Scramble Starfield 1/3 star width like scramble/galaxian, starfield code same as scramble. This one is similar to the Konami starfield video below. b) Bootleg Starfield Guru provided schematics of a daughter-board which on a Konami bootleg replaced custom chip 084. This starfield matches the starfield (picture) of this bootleg. None of the two alterntives reproduces the star field which can be observed in the Stern videos below. FIXME: For an exact emulation we need a 084 at some time. FIXME: The Konami video below is different from tutankhm. Looks like we are missing an early board dump Starfield videos ....
