Online Emulators for TRS-80!

I’m sure you’ve come here with the knowledge of the XRoar, MAME, CoCoPi and VCC emulators for the Color Computer and its family of hardware on your desktop/laptop computer.

Did you know there are a few emulators which run right in your modern web browser?

Try your hand at Microcolor BASIC 1.0 with an online MC-10 emulator. Or play your favorite CoCo 1, 2, or 3 games in the online XRoar available from the Color Computer Archive. But have you found the TRS-80 Model III javascript emulator?

The thumbnails above are links to their respective emulators.

I did a search to see what is available and this is what I’ve found. Are there more? Do you have an idea how to get the MAME emulation of the CoCos available in a browser? Up for a challenge? I’ve seen MAME booting other systems like the NES, SNES and maybe even an Atari 800.

If you’re able to find more, or build a working example… let’s see it!


Glenside Club Meeting: Thursday December 7, 2023 @ 7:30PM Central

Have a Happy CoCo Holiday!

With the season in full swing, treat yourself to that long awaited CoCo hardware upgrade or software title. If nothing else, think of the looks on your family’s faces when you open a vintage Tandy Color Computer 1 box wrapped (carefully, so as to not mess up the original packaging) and under the tree.

Please join us for our December meeting and ring out the year 2023, a great CoCo year! We’ll be considering the results of the meeting date/time poll (please cast your vote if you have not already), but otherwise have a light agenda. I hope we can take some time during or after the meeting for members to take a few moments and point their cameras to their current CoCo setup (big or small, real or virtual).

Please join us this Thursday. Since we have a belated board meeting that will be held immediately prior to our business meeting, we will be opening the call just a bit before 7:30PM.
