The pico-mac-nano project is the cutest thing I’ve seen in a while, and reminds me of the old SpritesMods ESP32 hack (which I think might still be a bit more functional), but has its own set of inspired hacks, and is readily available.
In fact, the ready-made version is quite tempting. There’s a wry nod to the old Mac, with references like the recessed T15 bolts and even a custom “Picasso” box for collectors.
I have no real use for it myself, but some sort of functional Mac Plus model on my shelf is still something I’d like to have, and this one comes very close–although I’ll probably whip up something with a Raspberry Pi Zero for more functionality…
