a built in PSU and 56-key keyboard. Initially a single board system, with 4K firmware, (1.5 Monitor, and 2.5K BASIC) and 3K of RAM and a 64x16 VDU, it could be expanded using a "passive motherboard" with eight slots with 64-pins DIN connectors for Eurocard shaped expansion cards, this way the system could be expanded to a complete CP/M based system. In 1980 the Triton was followed up by the Zilog Z80 and S-100 bus based Transam Tuscan. Transam ("Transam Components Limited") also wrote a Pascal compiler, "TCL Pascal" for the Triton, consisting of a 4K monitor/editor in ROM, and a 20K compiler for a total of 24K ROM. TCL Pascal was also available on a single 8-inch floppy disk, and ported to other systems, like the 6502-based Commodore PET. At much the same time, the Australian edition developed (in conjunction with Kim Ryrie) a complex music synthesiser, that subsequently had its commercially further-developed counterpart: Kim Ryrie's Fairlight Synthesizer. In 1980, Kim Ryrie sold the overseas editions, each to individual owners. The Canadian operation was bought by Halvor Moorshead in 1979, when the Australian company was acquired by Kerry Packer's Australian Consolidated Press. The UK company was sold to Argus Specialist Press (a subsidiary of BET). 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. Collyn left Federal shortly after to form a specialist technology publishing company with designer Alison White, and later his own publishing company, Caravan & Motorhome Books – which still (March 2014) exists. He also doubled as technical contributor to The Bulletin from 1982–1990, and later founded Australian Communications. Federal Publishing also purchased the long established Electronics Australia, but closed both publications some years later. ETI and Electronics Australia still survive in Australia – incorporated in Silicon Chip, run by ex Electronics Australia Editor, Leo Simpson (who bought the copyright to all editorial material of both publications). Halvor Moorshead remained in Canada where he ran successful genealogy publications and later a local community radio station. He died on 7 March 2014. The 1980s and 1990s Throughout the 1980s, ETI featured type-in computer programs submitted by readers. The last issue, Volume 20, Number 4, was published in April
