Key Benefits Over Original / Replacement Boards

- Remote battery holder (no future acid damage).

- ZERO surface mount components. This is not a throw away board. We ONLY do Through-Hole Designs

- No custom components.

- Socketed through hole connector for RAM Chip.

- All new (not 20+ year old) components and PCB

- All of our components match the original schematic component designators, so you can troubleshoot with the original schematics or our schematics!

Note:

This board is supplied without the game ROM, ASIC, Security Chip and Microprocessor. This is done to keep the price of the board as low as possible. 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. We can also transfer these for you, for a fixed fee, if you send us your old board, as the ASIC (square chip) requires a specialist tool. We will also test the board complete .Alternatively you can order the board with this chip new and fitted, or a complete board, with all chips fitted, ready to plug and play (except security chip which is also available from us, ordered seperately).
Now available, an option of standard battery backed memory (3 AA) or a no-battery solid state memory, never worry about batteries leaking again. Please select which option from the drop-down menu. Please email us if this confuses you.
