Are the SOUND and IRQ pins inputs or outputs? --Zzo38 (talk) 13:49, 11 March 2013 (MDT)

IRQ is the same open-collector shared line throughout.
SOUND is the audio after it's buffered, but before the expansion audio is mixed in.
I'll incorporate this into the page. —Lidnariq (talk) 13:57, 11 March 2013 (MDT)
