Early sample/prototype machines included a ring that would actually trap the balls during planet lock (AKA Deadworld). This was deemed a maintenance concern and the feature was changed to a virtual ball lock on actual production run machines before the game was released. Prototype games will have red boards.
L1-AT version is for production run machines that have added an aftermarket planet locking ring. Actual prototype machines have different wiring and need version L1. Both L1 and L1-AT do not contain any of the changes from later versions of the rom. Using L1 version in a production machine will throw a switch error and credit dot. L1-AT was created to fix this issue, and this is the only difference between the 2.
