Got some 74154n ICs off eBay to try replacing on the Jungle Lord MPU board and hopefully fix the missing digits on the 1st and 3rd player displays. Just need to find a few minutes to remove the old chip, install new machine pin sockets & the new chips. Figure I might as well add a new battery holder as well since I'm pulling the board so the game stops booting into audit mode due to not having batteries in there.
