3.2 Sound Boards
3.2.1 Squawk & Talk
3.2.2 Cheap Squeak
3.2.3 Turbo Cheap Squeak (T.C.S.)
The Turbo Cheap Squeak sound board was used on games like Strange Science and Motordome. The sounds it can produce are pretty basic.
The board features a 68B09EP processor, a 6821 PIA, 16K of static ram, and 256K of ROM. It interfaces to the MPU similarly to the Bally Squawk and Talk board. Volume is controlled by the pot at VR1.
3.2.4 Sounds Deluxe
3.3 Accessing Bookkeeping, Settings, and Diagnostics
3.3.1 6803 Keypad
As easy as "A, B, C".
4 Problems and Fixes
4.1 Power Driver Issues
This may not apply to some, as MPU might have been part of it.
4.2 MPU Issues
4.3 Power Supply Issues
4.4 Sound Issues
4.4.1 Sounds Deluxe Board
This sound board has a common problem with DAC failure. AD7533 chip is easy and inexpensive to replace. You can prevent failure by removing C12 (47 uf) capacitor. It seems to have no adverse affect but prevents a voltage condition on power down that can destroy the DAC.
The LED with flash a check sequence on power up. 6 Flashes ROMS and RAM are OK.
4.5 Display Driver Board
Possibly doesn't apply to some, can't think of an example.
4.6 Coins Register But Don't Credit Up
This is commonly seen on VPinMAME emulation, but applies to real life as well.
Coins drop OK, switch is good, game makes noise, but it remains on "Credits 0" and doesn't credit up.
Symptom is corrupted/blank NVRAM.
To fix, open coin door (make sure coin door switch is working, otherwise the keypad won't work), then do these steps:
Hit "Test", to enter operator mode.
Hit "A" until "Feature Options" is displayed.
Hit Enter.
It will say "Reset Factory Is".
Hit 6, then 5, then Enter.
Hit "Game" to return to attract mode. You'll know it worked because it will take longer than usual to reach attract mode, and the display will flicker slightly as the computer clears the memory (this is normal).
Intuitive and easy to remember, right? And Bally had the nerve to advertise "manual-free testing"....
