- Beefed up switch matrix drive for better durability (good to 100V back drive)
In addition:

- Major component designators carried over from original design so original schematics can be used.
- Jumpers and ROM configurations clearly labeled on silk screen
- Board comes jumpered for the 512k Game ROM (80% of games)
- Board comes with complete set of schematics
