Quoted from woodmedic:Could someone please confirm if a system 11b mpu would work with no problems in F-14 Tomcat? I am just wanting to confirm that the extra parts are not needed in the audio section that are missing on the "b" version that were present on the "a". Thanks!
That is correct, you can substitute the 11b "as is" for the 11a
The System11b CPU board is not quite as flexible as System11a or System11, because 11b is missing the U1 sound amplifier and associated parts. The System11b CPU will work "as is" in a system11a or system11c game. But these sound part must be added back for a System11b CPU board to work in a System11 game (High Speed, Road Kings, Grand Lizard).
