Summary 08285: trvchlng: DIPS for Coinage, True False Bonus and Attract Mode
Description Three DIPS for Triva Challenge:
This game is unplayable because the question rom
is undumped. The main program runs so we can
establish some funtioning DIPS.

1st Picture:
Highlighted DIP is for "Coinage"
ON = 2 Coins 1 Credit
OFF = 1 Coin 1 Credit

The DIP below this one is "Coin B"
ON = 1 Coin 5 Credits
OFF = 1 Coin 3 Credits
Change is seen when coining up.

2nd Picture:
Highlighted DIP is for "True or False Bonus"
ON = 300K
OFF = 200K
Change will be seen during attract mode.

3rd Picture:
Highlighted DIP is for "Attract Mode"
ON = Instructions Only
OFF = Full Attract
Change is immediate.

*** Maybe they thought Full Attract would cause seizures?!?
Steps To Reproduce Load and run game.
Set DIP as shown in picture.
Reset game and observe change.
Repeat for all Highlighted DIPS.

Hello again Steve;

 When you have a chance, check out 08284 Wink post again. I have figured out three more DIP settings. "Demo Sound" is not pictured but description is in the notes.
Thank you for your time.
