Amiga Transactor was published in Toronto. It was also widely available in the US. There were UK an Italian editions.
I used to write a column for Amiga Transactor. At one point I thought seriously about buying the magazine -- I'd arranged financing and was looking for editors and printers. But, I let reality prevail when, against my wishes, I realized that the Amiga would not survive. Transactor went away and soon after the Amiga did.
The editors of Amiga Transactor, Nick Sullivan and Chris Zamara, moved their software company, AHA!, to Vancouver after Transactor folded. No idea what they are up to today.
