My migration from the Oberon System 3 to the Raspberry Pi 2 and 3 comes at just the right time as it seems (see https://github.com/rochus-keller/OberonSystem3Native/release...). There is also a stand-alone version of the compiler that runs on all standard systems (see https://github.com/rochus-keller/op2/).

Maybe the company will extend the availability of the Model 2b for a few more years and release versions with less RAM (<= 500 MB)?
