Looks promising! Thank you very much! ^^

As a fun side project I created have created a "frontend" for my PC/XT emulator running on baremetal ARM (RasberryPi3) using the Circle library.
Code is here and you can download the latest binaries from https://virtualxt.org if you would like to try it out.

This was a superfun experience and I would recommend anyone interested in lowlevel coding to check out the Circle library. It really opens up the door to do some cool stuff on the RaspberryPi's. 😀

I've been wanting to build something like this but based on Linux. What kind of perf are you seeing on older RPis or ZW (not the faster/newer Z2Ws) Initial experiments show perf on ZW seem to give numbers somewhere between a 286 and a fast 386 but with a lot of variability. It's not completely a problem but I was hoping for something a bit better from the 1GHz clock.

Wow, that's great news! I love the idea running oldschool pc bare metal on a SBC like the Pi, since it opens the opportunity to build computers like the famous Schneider EuroPC.

Could you give some more information about the port? Seems it only runs on a Pi3 ? How about speed and accuracy ? How about compatibility (VGA, Adlib ...)

Unfortunately I don't own a Pi3 so I can't test myself ...
