 | | The Tandy TRS 80 model 1 was the first member of one of the most famous computer family. | | | The Model1 was followed by the TRS 80 model II (a business computer) and model III which had almost the same characteristics as the model I. Tandy Radio Shack | | | When it was connected to a floppy disk unit, the TRS-80 uses the TRS DOS operating system, it was pretty bugged and most of the TRS-80 users prefered NEW DOS, it was an operating system done by a third-party company called Apparat. |

| | Although in terms of software, the System 80 was a (near-) TRS-80 Model 1 clone, it's appearance, interfaces and idiosyncrasies were unique enough to justify it's own place in the sun in terms of microcomputer history. | | | This site is dedicated to the System 80, a TRS-80 Model 1 clone, popular in Australia and New Zealand in the early 1980's. | | | Over the years this site has grown and expanded and now contains a great deal of information not only about the System 80, but also its manifestations in other countries, EACA International and EACA computers generally. |
