Yep, so I'm now looking for the "HP-67 Byte Table"- if such a thing ever existed?
I seem to remember an article on PPC dealing with the HP-67 instruction codes, but again, it might be just a figment of my imagination...

My guess is that there must be a look-up table mapping 67-instruction codes to 41-byte_table values. Time for another wading session...
