The RadioShack TRS-80 Color Computer, later marketed as the Tandy Color Computer, is a series of home computers developed and sold by Tandy Corporation.Despite sharing a name with the earlier TRS-80, the Color Computer is a completely different system and a radical departure in design based on the Motorola 6809E processor rather than the Zilog Z80 of earlier models.
The TRS-80 Micro Computer System (TRS-80, later renamed the Model I to distinguish it from successors) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor]. [4] It is one of the earliest mass-produced and mass-marketed ...
Model 4. Tandy Corporation introduced the TRS-80 Model 4 on April 26, 1983 as the successor to the TRS-80 Model III. The Model 4 has a faster Z80A 4 MHz CPU, [ 5 ] larger video display of 80 columns by 24 rows, bigger keyboard, and can be upgraded to 128KB of RAM. It is compatible with Model III software and CP/M application software.
The original TRS-80 Micro Computer System (later known as the Model I to distinguish it from successors) was launched in 1977 and- alongside the Apple II and Commodore PET- was one of the earliest mass-produced personal computers. [1] The line won popularity with hobbyists, home users, and small-businesses.
The TRS-80 Model 16 came out in February 1982 [19] as the follow-on to the Model II; an upgrade kit was available for Model II systems. The Model 16 added a 6 MHz, 16/32-bit Motorola 68000 processor and memory card, keeping the original Z80 as an I/O processor, or as the main processor when 8-bit Model II software was loaded.
The TRS-80 MC-10 microcomputer is a lesser-known member of the TRS-80 line of home computers, produced by Tandy Corporation in the early 1980s and sold through their RadioShack chain of electronics stores. It was a low-cost alternative to Tandy's own TRS-80 Color Computer to compete with entry-level machines such as the VIC-20 and Sinclair ZX81.
Much software was developed for these computers, particularly the relatively successful Color Computer I, II & III models, which were designed for both home office and entertainment (gaming) uses. A list of software for the TRS-80 computer series appears below. This list includes software that was sold labelled as a Radio Shack or Tandy product.#.
