Oh, hey. I made that! Let me know if you have questions. This is the QT Py board that&#x27;s inside: <a href="https:&#x2F;&#x2F;www.adafruit.com&#x2F;product&#x2F;5426" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.adafruit.com&#x2F;product&#x2F;5426</a> It&#x27;s connected to this display: <a href="https:&#x2F;&#x2F;www.adafruit.com&#x2F;product&#x2F;5206" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.adafruit.com&#x2F;product&#x2F;5206</a> Via this adapter: <a href="https:&#x2F;&#x2F;www.adafruit.com&#x2F;product&#x2F;5772" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.adafruit.com&#x2F;product&#x2F;5772</a> Here&#x27;s the example CircuitPython code that it ships with: <a href="https:&#x2F;&#x2F;codeberg.org&#x2F;trevorflowers&#x2F;tiny-trs-80-model-iii&#x2F;src&#x2F;branch&#x2F;main&#x2F;circuit-python-src&#x2F;default-code.py" rel="nofollow noreferrer">https:&#x2F;&#x2F;codeberg.org&#x2F;trevorflowers&#x2F;tiny-trs-80-model-iii&#x2F;src...</a> Here&#x27;s a quick video of me making the non-electronic version of the same model: <a href="https:&#x2F;&#x2F;diode.zone&#x2F;w&#x2F;7DvD6MmCdF9dQS3ioWomGy" rel="nofollow noreferrer">https:&#x2F;&#x2F;diode.zone&#x2F;w&#x2F;7DvD6MmCdF9dQS3ioWomGy</a> The electronic version just has a bit more soldering and setup.<p>Oh, if you&#x27;re on the fediverse then you can find me at @trevorflowers@machines.social.

I love miniaturized computers like these! It&#x27;s hardly practical to own and keep out all of our beloved &#x27;70s and &#x27;80s computer, but if they were all available in sizes like this, well, I&#x27;d have to have the whole set :)

this is nice! wonder what it would take to make it emulate a small DOS like environment. the qt py has an esp32s3, which afaik is quite a beast for a microcontroller.
