So, others here are the real experts on the WP-34S, not me.

While I'm very impressed by enthusiasm people have gone to in making what is simply a programming adapter, I'm rather disappointed in the completeness of the documentation. Recall that we've been re-purposing 20b and 30b calculators for almost seven years, yet most people look no further than this forum in doing their research and completely overlook the Old Forum and the six years worth of experience re-purposing calculators that can be found there.

Lets not forget:

• Richard Nelson's Interfacing to the HP20b V3
• The HP20b Development Kit, released by Cyrille, which includes schematics of the calc
• Harald Pott's USB adapters
  

While sometimes the journey is half the fun, building a programming adapter is simply a means to an end. If you're only interested it turning a 30b into a WP 34S or WP 31S then save yourself a lot of frustration and time, get a ready-made adapter and show some support for those who followed this path before you.
