Press Cuttings This advertisement was published in Popular Computing Weekly 31 Jan 1985. It features Mistertronic. More important, it talks about capital investment in the USA and mentions an address for Mastertronic International Inc in New York. At this time Mastertronic games were duplicated and distributed by an independent company based in Frederick, Maryland. Stewart Conway (someone's brother-in-law, I suspect) was the mysterious occupant of suite 401, 16 Park Avenue South, and from dim recollection I don't think he ever achieved very much for us. In later years we had no difficulties in finding sources of product but in early 1985 Mastertronic was still trying to establish its prescence on both sides of the Atlantic.
