After reading the article in March 3, Electronics, the HP people make much 
of the millicode concept.. i.e. small bursts of RISC instructions that do some
higher-level task. In 3000 emulation, millicode would emulate individual 
instructions. I don't know exactly how 3000 emulation is done, but this
seems to be the missing clue. All that's required is a small interpreter
underneath the "3000 interface" to translate 3000 instructions to millicode
lookup. Details were rather lacking in the Electronics article, but a little
intuition leads to the conclusion above.

Can anyone at HP comment?
