The Konami '0005292' is one of the varios custom ICs you can find on Konami 'GX400' arcade system, more precisely on the video board.You can read more about the GX400 hardware here :
The '0005292'comes in a SDIP64 package :
Technically the chip is a counter/clock divider providing all video timing for the system, here's pinout from Nemesis schematics :
For my reproduction job I used a Salamander bootleg where the functions of the chip have been reversed by using simple 74 logics.After identifying the equivaent circuit I made a replacement based on CPLD :
After some timing clock adjustement the replacement worked fine, here is testing on my Black Panther PCB :
In the next future I will look at the other GX400 custom ICs with the aim of doing a replacement of the whole video board, stay tuned for further updates.
