Developer ericjenott says the system is designed to emulate an IBM XT computer with an 80186 processor and 1MB of RAM, although the actual processor is an ESP32 microcontroller.

It’s really too bad you can’t run Windows 3.1 on it. It requires at least a 286, but a 386 would probably be needed if you want to run games.

Is there any point to running Windows 3.0? It was way before my time, even with Windows 3.1, I first encountered it as kid in 95/96.

I personally don’t see the point in devices like this. Why not just run an emulator on a PC or laptop? Do you really need hundreds of hours of battery life for fooling around with retro stuff? Not to mention an e-ink screen is absolutely garbage for anything besides terminal work.

Also most enthusiasts prefer the real thing anyway. They will buy a retro computer and use the software that was used on it back in the day.
