LOTR and most Sterns have an 8 x 10 lamp matrix so he would have to add 2 more rows to his board.

Stern's use 19N06L mosfets for the columns and VN02 relays instead of TIP107's and TIP102's as on all of the williams boards.

However it looks to me like the board might already be downwards compatible all the way back to system 3 Williams games since the hardware for the lamps didn't really change much except for the removal of the large resistors. If so should work on the data east and non-whitestar segas.

Capcoms are basically the same as the Sega Whitestar and Stern matrixes only 8x8 instead of 8x10

22N10L mosfets for the rows and VN02 relays for the columns, but it's a pair of 8x8 matrixes so you would need two of these boards to work in a Capcom
