Ahh, Bend. Cool place and people. Sadly an ex girlfriend was involved so haven't been there in 12 years.
So, what you need is an interface that will take the line outputs from the ADAT recorder. What is the model? I had 2 38's and a 88 if I remember correctly they had RCA jacks out right?
You may get off cheap by getting a Behringer Ultragain Pro-8. I only use the unit as a backup digital slave ADAT input for my better interfaces, but I assume it has it's own drivers.
You would obviously need also a DAW (recording software) and computer to run it. Reaper would be your most cost effective software there. Others here will help with that setup.
