Digital Audio And Anaogue Audio And Adat And ... Options

[sadcba]

Hi
I'm a apple user for years now and was always really pleased until os9 turned to osx and I was left in the cold with my creamware pulsar system.

But now it's G5 time for me at last and Logic pro time also, and I was wondering if I could link my G5 with it's analogue output to the monitors, and with the digital connectors to my old and trusty G4 400 mhz wich will function as my digital mixer running pulsar.

or do I need a special box to have multiple I/O

if so what would you guys recomend to use

best regards
