Introduced in 1977, the TRS-80 was a pioneering microcomputer that played a vital role in the early days of personal computing. In this blog post, we will take a closer look at the TRS-80, its features, impact, and lasting legacy. The TRS-80: The TRS-80, also known as the Tandy Radio Shack-80, was an affordable and accessible computer designed for home and small business use. Powered by the Zilog Z80 processor, it offered a modest 4 KB of RAM (expandable up to 48 KB) and utilized cassette tapes for storage. The machine featured a full-stroke keyboard and a monochrome text-only display. Impact and Legacy: The TRS-80 played a pivotal role in popularizing personal computing, as it was one of the first microcomputers to reach a wide consumer audience. Its affordability and compatibility with third-party software made it attractive to hobbyists, educators, and small business owners. The TRS-80 also fostered the growth of a vibrant software market, with a range of applications available for users. Despite its technical limitations compared to today's computers, the TRS-80 laid the groundwork for the digital revolution that followed. It inspired a generation of computer enthusiasts and professionals, shaping the trajectory of the technology industry. CoCoIO is based on the WizNet 5100s ethernet chip. This amazing device can manage 4 separate TCP or UDP network stacks all by itself, the host computer's only job is to feed these pipes. Some applications can be written in basic! I'm describing a simple web browser in the blog section of this site. Major update coming soon. Which is fun, but we need real software, and at least two talented guys have stepped up. Mike 'n6il' Furman is well on his way to drivewire over ethernet, and the mysterious 'strickyak' is writing the rest of the BSD socket (things like arp,dig,ping,dhcp,ntp,tftp).
