I'm not 100% certain, but I think that's what Digital_Trucker started with for the PT-109 mod. Are you wanting to start "fresh" on one of your own? s7rikeback has a recent write-up somewhere around here about taking an AI vessel and making it "driveable". There are a couple other write-ups similar to that one, and I think ETR3(SS) has one on subs... ?? I'll see if I can find those.
