...but that's exactly the claim, restated.

Not really. It's completely trivial, if extremely slow (which the article acknowledges) to emulate an ALU in software, with access to a single, universal hardware gate. Why don't they just say "we put a NOR gate on a chip, then added all this other stuff (RAM, boot EEPROM, etc.) to make it function as a computer." That would, at least, be a non-misleading statement of the claim.

Yes, it's a "Single board computer with 20 ICs, and a single-gate ALU".

To me it's not really an ALU either, since the NOR gate doesn't really do the job I expect from an ALU.

That’s how I interpreted the OP though... I really don’t know what you were reading into it.
