I was expecting Andy Warren or John Payson or someone else
to come up with this one easily. No problem says I we have
written 80 assemblers in the last 15 years just grep the sources
for A2 and find out who uses it for a JMP. If that fails (it did)
we have a box of instruction cards many of which saw use with
very little silicon it has got to be one of those. Dump 'em out
on the conference room table, dust off a paper tape copy
(this box goes way back) of micro-chess, and micro-aid in the
layer above the IBM 1620 instruction card I went from the
extinct Signetics 2650 to the obsure Monolithic Memories 67110,
National SC/MP and at least 50 others, It isn't PDP11, M68K
Unless I missed somthing nobody uses the opcode A2 for a jump.

So there you have it folks A2 is available as patentable opcode
all of which does solve the question at hand.

BTW Paul are there any more clues
