Thanks! We sold about 30 CPUs of the old version, then we had to stop because the main component was not available for years, right after the pandemic. Now we use an alternative component that is also less expensive and we have added several new features. The current development board is not fully functional, we are working on ETH, RTC and also fixing a few other things. We expect it to be fully functional and available by April 2025. The OS is actually just very simple; it boots an image from SD, sets up the interrupt table, initializes a list of free memory and that's it for now. This part will be OpenSource so that we can take inspiration to make something better. The development board (mainboard) will also be open hardware and should be listed on GitHub. The macro assembler is freeware, but only because (currently) the code is really a bit messy!
