Ended up with 2 Data East power supplies in a board lot I picked up. Numbers are:
520-5047-00 Rev C
520-5047-01 Rev B
Reading up, looks like they were used in: Checkpoint, Teenage Mutant Ninja Turtles, Batman, Star Trek, and Hook; at least for the -00. I believe the -01 can be used in place, but not 100% sure. They're both in good condition, don't see anything visibly wrong with them.
Asking $60 for both. Can ship if needed, can't imagine cost being much.
