Doesn't the nano-controller use the HP 2116
architecture and commands, like
the BPC and other earlier HP processors like the ones in HP 98X0 series ?
It's quite likely, but I've never seen it stated anywhere. As you know
the 9800 instruciton set is differnt to that of the 2116 too (although
the basic instructions are, AFAIK, the same).
Maybe I should pull the ROMs from one of my naoncontroller-based devies,
run them throguha disassembler and see if the resulting code makes any
sense.
