Radio Shack TRS-80 Model 100 Notebook-Style Computer (1983)

✅ Radio Shack TRS-80 Model 100

🥇First Commercially-Successful "Notebook-Style" Computer 

The Radio Shack TRS-80 Model 100, released in March 1983, was the world’s first truly successful "notebook" computer and a masterpiece of practical design. Originally developed in Japan—and famously featuring the last operating system software that Bill Gates personally helped write code for—the Model 100 was an instant hit with journalists, reporters, and field engineers. Its appeal lay in its pure simplicity: it featured a wonderful, clicky mechanical keyboard and a sharp, 8-line LCD screen that was perfectly readable even under bright, direct sunlight. Because it could run for nearly 20 hours on just four standard AA batteries, a reporter could comfortably write a full story on an airplane, plug the unit straight into a public phone booth using its built-in modem, and transmit the text to the newsroom before the plane's engines even cooled down.
