pin 2: Amplifier in (5B), no connect (5A), or PRG A18 (FME-7)
pin 3: Amplifier out (5B), or no connect (5A and FME-7)
pin 18: Audio /disable (5B) [1], unknown input (5A), /EXT IRQ (FME-7) - all three chip variations have internal pull-up
pin 27: Audio out (5B), no connect (5A), or VCC (FME-7)
On FME-7, the two ground supplies and three VCC supplies are shorted internally. Boards (like GRM-E301) that were used with the 5A or 5B did not connect pin 27 to VCC
