I'd like to also mention that Keith spearheaded the Synthetic Routines section for the PPC ROM, containing 67 routines and programs.

The layout is a bit different than the original article. If you prefer to read the original one, have a look at the hpseries80 group on (needs registration).

For what it is worth, the PPC Archive (with details here) contains V1N1 through V1N5 plus V2N1 - V2N3 and V2N5 of Professional Computing. If anyone out there happens to have access to a copy of V2N4 and would be willing to lend it for scanning (or would be willing to scan it), I would be most appreciative. Please send me a PM.
Thank you,
