Tandy Corporation, originally a leather goods company founded in 1919, became a significant player in the personal computer industry in the late 1970s through its RadioShack division. Here's an overview of Tandy's journey in computer manufacturing:
🧵 Origins and Entry into Electronics
1919: Tandy was established as a leather supply store in Fort Worth, Texas.
1963: Tandy acquired the struggling RadioShack for $300,000, marking its entry into the electronics market
Hackaday.
1977: Tandy introduced the TRS-80, one of the first fully assembled personal computers, through RadioShack stores.
💻 The TRS-80 Era (1977–1980s)
TRS-80 Model I (1977): Launched at $599, it featured 4 KB of RAM, a Zilog Z80 processor, and ran on cassette storage. It became one of the first mass-produced personal computers
WIRED.
TRS-80 Model III (1980): An improved version with a built-in monitor and disk drives, catering to small businesses and schools.
TRS-80 Model 100 (1983): A portable computer with a built-in modem, popular among early telecommuters

What are the advantages of Tandy over Commodore?

ChatGPT:

Comparing Tandy (RadioShack computers, e.g., TRS-80, Tandy 1000) with Commodore (e.g., VIC-20, C64, Amiga) in the late 1970s–1980s, several advantages of Tandy emerge, especially in business and compatibility contexts:

IBM PC Compatibility
The Tandy 1000 series was designed to be largely IBM PC-compatible, allowing it to run a wide range of business software (e.g., WordPerfect, Lotus 1-2-3).
Commodore 64/128 were not PC-compatible, limiting them mostly to games, education, and hobbyist software.
Advantage: Businesses could adopt Tandy machines without worrying about proprietary software constraints.

Keyboard and Build Quality
Tandy computers often had full-sized, comfortable keyboards and integrated components (disk drives, monitor) in later models.
Commodore machines like the C64 had smaller, more “toy-like” keyboards, which were less suitable for heavy typing or office work.
Advantage: Better ergonomics and durability for professional use.

Software Ecosystem for Productivity
Tandy focused on productivity software: word processors, spreadsheets, accounting tools, and educational programs.
Commodore’s ecosystem was heavily game-oriented, though it had educational titles.
Advantage: Tandy appealed more to small businesses and schools that needed serious computing.

Display and Graphics for Business
Tandy 1000 supported CGA graphics with some Tandy-enhanced modes, giving clearer text and acceptable graphics for business apps.
Commodore 64 had excellent gaming graphics and sound but was less suitable for text-heavy business applications.
Advantage: Tandy’s video was more practical for office applications.

Modularity and Expansion
Tandy computers often had expansion slots and peripherals that made them more adaptable to office environments (printers, modems, disk drives).
Commodore machines had expansions too, but many were proprietary and less standardized, making upgrades trickier.
Advantage: Easier integration into professional setups.
⚖️ Summary
Feature Tandy Advantage Commodore Advantage
IBM Compatibility ✔ Runs business software ❌ Mostly games/hobbyist software
Keyboard & Build ✔ Full-size, robust ❌ Smaller, less ergonomic
Productivity Software ✔ Word processors, spreadsheets ❌ Limited, game-focused
Display for Business ✔ Text clarity, usable graphics ✔ Superior gaming graphics
Modularity/Expansion ✔ Easier to integrate peripherals ❌ More proprietary expansion
In short:
Tandy = business and school-friendly, PC-compatible, reliable keyboards, professional software.
Commodore = better for games, graphics, and home/hobbyist use, but weaker in office productivity.
