@ -32,10 +32,86 @@ These boards use two 8910's for sound, controlled by a dedicated 6502. The
|

main processor triggers an IRQ request when writing a command to the sound

CPU.
|

|
||||
Main clock: XTAL = 12 MHz

Horizontal video frequency: HSYNC = XTAL/768?? = 15.625 kHz ??

Notes:
|
||||
6502 - clock 500.0kHz [12/24]
|
||||
AY-3-8910 - clock 3.00MHz(both) [12/4]
|
||||
2128 - 2k x8 SRAM == 6116
|
||||
X - Position for a socket, but not populated with anything
|
||||
DIP24 - Empty socket. There are rumours that this socket would hold test mode code or something else.
|
||||
It's possible a factory test ROM did exist for factory-only testing as this was common with
|
||||
several manufacturers at the time. However the PCB came from the factory with this socket empty
|
||||
so it would be extremely unlikely to find a PCB with that socket populated.
|
||||
SW1/2 - 8 position DIP switches
|
||||
To set cocktail mode, set DIP#1 SW7 & 8 OFF. The player has 2 buttons only and the screen will flip between PL1 & PL2
|
||||
To set upright mode, set DIP#1 SW7 & 8 ON. The player has 3 buttons and the screen will not flip between PL1 & PL2
|
||||
DIP Notes:
|
||||
SW1 #5 is unused
|
||||
SW1 #6 must remain OFF otherwise the game will not boot-up and just displays garbage.
|
||||
There is no TEST mode.
|
||||
SW2 #5 is listed in the manual as "Panel B". This enables or removes the 2nd button.
|
||||
There were two types of panels supplied, either cocktail or upright cabs. The cocktail panel
|
||||
doesn't have 3 buttons. The 2 buttons are air-air missile and air-ground missile/bomb and
|
||||
there's an extra button for accelerate on the 3 button panel. On the 2 button panel, button 1 is
|
||||
the air-air and air-ground missile/bomb weapon button and is auto selected based on the enemies on
|
||||
screen and the 2nd button is wired to accelerate. There is no button for manually selecting
|
||||
the missiles/bombs.
