![]() The TRS-80 Model I home computer was introduced by Radio Shack in North America just as the build-it-yourself Heathkit era was ending and the Apple II era was beginning. So, at the urging of the good people at the CASA Solution Archive, I hope to help remedy that with this post. I'm particularly fond of the vintage Radio Shack TRS-80, the machine I cut my computing teeth on way back when, and there aren't a lot of good "how-to" guides on the Internet. And emulators take up a lot less physical space than the real thing, slight inaccuracies notwithstanding my laptop is wonderfully schizophrenic, and much of what I do here would be difficult or impossible without this technology.īut it can be daunting to get an old system up and running past the initial boot display game consoles aren't too frustrating, but an unfamiliar computer platform can be maddeningly cryptic. Today's machines are fast enough to simulate entire hardware systems of decades past, with superior speed and "free" virtual hardware upgrades like multiple disk drives and expanded memory. There are also fun things to try, hardware, free programming books and tutorials, and much more.Retro gaming in the new millennium depends heavily on emulation technology. There are hundreds of in-depth reviews, open source alternatives to proprietary software from large corporations like Google, Microsoft, Apple, Adobe, IBM, Cisco, Oracle, and Autodesk. The software collection forms part of our series of informative articles for Linux enthusiasts.

TRS-80 Softwareīy 1979, the TRS-80 had the largest selection of software in the microcomputer market. We are also admirers of the SDLTRS project although it’s not as full-featured as trs80grp. It can run at full PC speed, supports Model III high speed cassettes, and has a built-in Z80 debugger. The emulator supports DSK, DMG, IMG and HFE disk formats. The emulator provides ROMS for the Model I, III, 4, and 4P. There’s also support for the TRS-80-DT-1 and Videotex terminals. ![]() This includes the TRS-80 Model I, II, III, 4 and 16 Microcomputers, and others. It emulates the “gray” line of TRS-80 computers made by Tandy in the late 1970s and early 1980s.

It spawned a whole series of later models that used the TRS-80 name even though they were unrelated. It is one of the earliest mass-produced and mass-marketed retail home computers. The TRS-80 Micro Computer System (renamed the Model I) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation.
