While otherwise identical, multiple revisions of the board exist. Older boards that were installed in Cruis'n Exotica cabinets have a Disk ASIC JR revision A8, whereas newer boards in deluxe cabinets and all revisions of The Grid have a Disk ASIC JR revision AB. While Cruis'n Exotica appears to accept either version, The Grid must have an AB revision chip otherwise several banks of ROMs will fail to read properly. Note that it has been confirmed that swapping an A8 chip for an AB chip is possible and causes the Grid to play properly on a board previously meant for older revisions of Cruis'n Exotica.

There exists also two revisions of the PHY chip that handles firewire linking. On some boards, only one physical connection exists and the chip can only handle one link. On others, two physical connections exist and the chip can handle up to 3 links. If U8 has the text "IBMX50" on it, then it is capable of 3 links. If it has the text "IBMX51", then it is only capable of 1 link.

In order for CMOS settings to persist, both the SRAM located at U26 and the Snap-Hat settings chip at U47 must be working with operational batteries. If either is dead, the game will reset all settings every boot. For the Snap-Hat, you can simply replace the hat itself with a new one that is good. They can be found on eBay or most electronics sites. For the SRAM, unfortunately they are end of life. The best thing to do is to dremel down the top of the chip until you reach the epoxied battery, tear it out and then solder in a 2032 holder. You can determine which lead is the negative lead as it will beep out (0 ohm fully conductive) to the GND pin of the SRAM itself. Then, you can install a new 2032 battery and be back up and running.
