Three phase and IBM

[Brian Knittel]

Anyone have direct, real-world experience in setting up three phase for IBM gear, particularly the 3880 and the 3803 (dasd and tape) controllers? I need to know how to determine if the setup needs to be wye or delta. And, if you're local to the SF Bay Area, there will be some smoke-test parties coming up. (Scary parts of the work performed by a licensed electrician).  Hands on help before, during and after will be appreciated. Pizza will be provided.
