The $69 registration/upgrade fee provides additional capabilities - like the ability to save state, handy for jumping in and out, and full EPSON dot-matrix printer emulation - but I'll focus on the free version here, it will be sufficient for our purposes. It runs well in contemporary Windows environments, and the freeware version is very capable. The emulator I use is Matthew Reed's TRS32. The Model I was later superseded by the Model III, which was a very similar machine in a more businesslike casing the Model 4 followed as a logical revision of the III, before the IBM PC arrived and most of the competition dropped out of the industry. Graphics resolution was very low - 128 x 48 - and there was no built-in sound hardware, so arcade style games were not its strong suit. It was a simple, black-and-white computer, with a mere 4K of RAM in the low-end model and a maximum of 48K, but it had a decent Z-80 microprocessor and a dedicated monitor, permitting 64 columns of text. 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. Retro gaming in the new millennium depends heavily on emulation technology.
