Title: Falcon Games
Post by: channelmaniac on November 01, 2012, 12:15:21 AM
Model: Falcoln Crazy Kong
Tip: Pinout

Seems there are several different pinouts on the web for Crazy Kong and I could not get any of them to match up with the ground and power pins on a Crazy Kong game that was on the bench.

This is the pinout for the 18/36 pin edge connector version of board. This particular board has 2 edge connectors on it and both are the exact same pinout, but the connector slides on upside down on the edge connector on the side compared to the one on the end of the board. This is for the edge connector on the end of the board, looking AT the edge connector from the edge of the board:

Model: Crazy Kong Part II
Symptom: Dead

Fixed smeared solder short on bottom of board. Board would come up but had multiple pictures interlaced horizontally and vertically on screen. Music played too fast.

Horizontal and Vertical sync outputs were both too fast. Replaced 74LS161 at 7A and 8A and patched an open trace on pin 9 of IC at 8H to fix horizontal sync problems. Replaced 74LS74 at 6P and 74LS161 at 6R to fix vertical sync and sound speed issues. Tested board.
