Got a few boards today.
One of them is an original Capcom 1943 board.

Game had no sound at all.
After a quick look over the problem became apparent.

The EPROM for the sound was missing its GND leg. I replaced this with a 27c512 (data doubled up) for now as I seem to be out of 27c256 EPROM’s.
Game is fully working now.
