Earlier quoted context omitted.
The availability of the board to run Wirt's system was an issue pretty soon. There were even people who offered their own boards to fill the gap (e.g. https://web.archive.org/web/20160831063355/http://oberonstat... ). My system version instead runs on RISC-V, so no custom FPGA implementation, currently on an emulator, but eventually on the ESP32 (which has a much better availability).
What do you think about ClockworkPi uConsole Kit R-01, ClockworkPi DevTerm Kit R-01, OrangePi?
I have mostly experience with the smaller (older) boards of OrangePi, and I think they have great boards, some even with a long availability.
