The Transactor was no the TPUG Magazine, it was seperate. It was a very Technical Magazine and started with the C64. The Amiga version of the Magazine was called Amiga Transactor. At one time I had most of the Transactor and Amiga Transactor issues but discarded them when I last moved.
I believe the Magazine was Published in Canada (Specifically Toronto,Ont.) and had limited distribution in the US.
