Frogger
I bought a Frogger board in a box lot. It
is supporsed to be working. I later bought a beautiful
Frogger Cocktail, all original, no boardset. I tried to put
them together, but did not achieve the desired result.
Pin Out
The first thing to do was discover what
voltage was supposed to go to which pin on the PCB Edge
Connector. This mystical code is called a pinout. Each
manufacturer seemed to have their own favorite pinout.
Often they had multiple pinouts for different games.
Sometimes they would stick with a configuration for a few
years. Sometimes the same game is manufactured by different
companies and they each have a different pinout!
This is the case with Frogger. Frogger is a Konami game
distributed by Sega. The Konami boars have the Konami
Generic Pinout. That is the board I have so I will discuss
it here. There is another Sega version of Frogger with a
22/44 pinout. I do not have one to test, so I will stick
with my Konami 18/36 pinout. Some of the pins are marked
N/A because Frogger does not use the control related to the
pin, but other Konami classics might. The Normal Konami
function is listed in parenthesis.

Troubleshooting
Like I said, first try failed. Time
to check the voltages.
