It is believed that it was, in part, the quality of these designs which set ETI apart for its competition, and ensured its success, initially in Australia and then in overseas markets.
Collyn Rivers states that what assisted the magazine's success was having a long established and very high quality competitor in Electronics Australia.
There were initial teething problems, but it began to work following the appointment of Halvor Moorshead as editor/publisher for the UK market.
In the Netherlands a Dutch version was published as "electronica top internationaal" by "Radio Rotor", a mail order company for electronic hobby equipment located in Den Dolder (the Netherlands) and Brussels (Belgium), later they moved shop to Amsterdam where they are still operational.
There was also, for a time, a pirated Indian edition that Collyn Rivers decided 'not to know about' on the basis that it was needed but non-affordable by its young readers.
Whilst the major constructional projects continued to be produced in Sydney, the overseas editions were encouraged to be free to interchange material, but to be otherwise editorially independent.
Unusually for a publishing operation, Collyn Rivers preferred to hire people who had expertise in specific fields other than journalism.
This provided greater subsequent employment opportunities: ETI Australia's assistant editor Jane Mckenzie, for example, subsequently became editor of Choice; Barry Wilkinson's successor, Alan Waite, ended up owning one of Australia's largest security equipment companies.
In November 1978 the British edition of ETI published an article describing the schematics and other technical details (including PCB) of an Intel 8080 based single board computer called the Transam Triton, which could also be bought as a kit, including a specially designed metal enclosure with a built in PSU and 56-key keyboard.
The subsequent edition editors and Collyn Rivers (previously managing editor of them all), with Halvor Moorshead's encouragement and assistance attempted, with some success, to continue to maintain the previous cooperation, but this came to an end when, in early 1982, ACP sold the Australian group to Federal Publishing.
Halvor Moorshead remained in Canada where he ran successful genealogy publications and later a local community radio station.
