TRS-80

<computer> A series of personal computers sold by {Tandy Radio Shack}. The '80' refers to the use of Zilog Z-80 processor (NOT Intel 80x8x). There were 7.5 computers in the TRS-80 line: Models I, II, III, 4, 100, 102, 200. The Model 4P was a portable version of the Model 4 with no tape drive -- only 2 1/2-height single sided disk drives. Later models that Radio Shack produced were not TRS-80 machines -- they were based on the Intel 80x8x architecture. These included Tandy 1000, Tandy 2000, Tandy 3000, and others. The 1000 had a proprietary Color card. The 2000 was a powerful machine for its time, but was based on the {Intel 80186}, so when IBM didn't build a computer based on this chip, it failed. It was used to design a boat for the America's Cup. The TRS-80 GUI, DeskMate, was proprietary, but no more than Windoze at the time. Many joke about "TRaSh-80" machines but several models were in fact classics of their time. (1996-02-18)

TRS-80

The TRS-80 Micro Computer System (TRS-80, later renamed the Model I to distinguish it from successors) is a desktop personal computer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor]. It is one of the earliest mass-produced and mass-marketed retail home computers.

The TRS-80 has a full-stroke QWERTY keyboard, the Zilog Z80 processor, 4 KB dynamic random-access memory (DRAM) standard memory, small size and desk area, floating-point Level I BASIC language interpreter in read-only memory (ROM), 64-character per line video monitor, and a starting price of US$600 (equivalent to US$2,700 in 2022). A cassette tape drive for program storage was included in the original package.

While the software environment was stable, the cassette load/save process combined with keyboard bounce issues and a troublesome Expansion Interface contributed to the Model I's reputation as not well-suited to serious use. It lacked support for lowercase characters, which also hampered business adoption.

An extensive line of upgrades and add-on hardware peripherals for the TRS-80 was developed and marketed by Tandy/Radio Shack. The basic system can be expanded with up to 48 KB of RAM (in 16 KB increments), and up to four floppy disk drives and/or hard disk drives. Tandy/Radio Shack provided full-service support including upgrade, repair, and training services in their thousands of stores worldwide.

By 1979, the TRS-80 had the largest selection of software in the microcomputer market. Until 1982, the TRS-80 was the best-selling PC line, outselling the Apple II series by a factor of five according to one analysis.

In mid-1980, the broadly compatible TRS-80 Model III was released. The Model I was discontinued shortly thereafter, primarily due to stricter Federal Communications Commission (FCC) regulations on radio-frequency interference to nearby electronic devices. In April 1983, the Model III was succeeded by the compatible TRS-80 Model 4.

Following the original Model I and its compatible descendants, the TRS-80 name became a generic brand used on other unrelated computer lines sold by Tandy, including the TRS-80 Model II, TRS-80 Model 2000, TRS-80 Model 100, TRS-80 Color Computer, and TRS-80 Pocket Computer.
