Dave Patterson, of Berkeley, wrote the first paper proposing a RISC
architecture after spending some time working at HP, and, except for the
register windows, which resemble a feature of the TI 9900 processor, his
proposed machine closely resembled the micro-machine in the old HP3000s, even
to the names of the fields in an instruction.  In effect, his RISC machine
had user programs written in microcode.  It shouldn't be surprising if a RISC 
machine resembles the HP3000.
