– All of our components match the original schematic component designators, so you can troubleshoot with the original schematics or our schematics!
Note:
Most of our distributors offer this board without game ROM, ASIC, Security Chip and Microprocessor. Â This is done to keep the price of the board as low as possible. Â The Game ROM, ASIC and Microprocessors rarely go bad and are socketed so they can be moved from the original board to our board with minimum of effort. Â Please check with the distributor you choose to see which chips you may need to move! Â Call us direct if this confuses you.
