G4-450 AGP Audio Connector Spes?

[Richard Kriss]

I am placing an order for a SignaLink sound card interface unit (for a ham
radio PSK31 application) and they want to know what connectors are required
to mate to the Mac G4's audio in and out ports.  They are used to dealing
with PC sound cards and I have never owned or seen a PC sound card.

I have no idea what connectors are used on the G4 AGP and Apple never
defines anything in the manaul.  My guess is they use the standard 3.5 mm
stereo connectors; however, Apple has been know to use non standard items.

Can anyone confirm what connectors should be used?
