For this example, I will recommend the Scott Adams adventures, as Mr. TRS32 supports a number of different formats, detailed in step 5 below. Virtually insert the virtual boot disk in Drive 0 by accessing the Storage menu, Insert floppy disk option, and clicking on drive 0 then browse and select the boot disk image. You can at this writing find the NEWDOS boot disk at the System-80 site, here. I like NEWDOS, and will use it for the examples below, but it's very similar to the classic Radio Shack TRSDOS ( triss-doss) and the same commands should work in both environments. Then point TRS32 to the ROM directory by starting it up, then accessing the Options menu, ROM image path option, and browsing to the location where you have stored the model1.rom file.

The most stable source I have found is the System-80 site in New Zealand, which celebrates the local variant of the TRS-80 you can at this writing download the system ROMs here once you have retrieved the. There's only one file you really need, named MODEL1.ROM. If you have the original hardware, then you're arguably in the clear. This is a legal gray area - the original ROM contents are still under Tandy and Microsoft copyright, but their real-world market value has plummeted to near zero and no one has seen fit to hassle the hobbyist community or make an officially licensed emulator available (yet). Step 2 - Track down the TRS-80 boot ROM images. The link is currently labeled TRS32 Model I/III/4/4P Emulator as new versions come out, it may change, so I won't link directly here.

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The Model I was later superseded by the Model III, which was a very similar machine in a more businesslike casing the Model 4 followed as a logical revision of the III, before the IBM PC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.

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.Д«ut 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.
