Interestingly, the Raspberry Pi was designed at around the same time as
our effort and the Pi's success then was certainly not at all assured.
I agree it's cheap and handy, and we use it in parts of the System
Construction course at ETH precisely because of that.
But when we progress to a hands-on case study showing how everything
works from the ground up, the RISC system running Oberon on the FPGA is
so much more appropriate.
I am perhaps just in a different place on the "fairly clean" and "quite
simple" scales than you. ;-)
BTW I do think it's a scandal (but not surprising) that parts of a
computer targeted at education are under NDA. But much has been written
elsewhere about that. Then again, I don't think even the Micro:bit is
completely open. And even that is waaay more complicated than our RISC
computer, though less powerful.
