SEC's use serial data that is supplied via PL2 from the H8, note acceptor is also supplied from the main mpu on serial port 2, unless it uses a parallel connection then it is supplied by the hopper board.
All sorted now, made up loom to get SEC running in real rig to test roms for implementation hopefully into the emulator to run newer games that require the SEC meter.
Oh, PS. forgot to say thank you.
