well, technically you can get rechargeables in an LR44 size...
Yes, but the described LR44 batteries are by definition not rechargeable. A rechargeable equivalent would not be an LR44.

now given that these calculators shipped with batteries installed (yes?) i wonder what condition those batteries are in after sitting there in the calculator for all these years?
Yes, the Pioneers (and Voyagers) were shipped with batteries installed. I suspect these have been installed for about 15 years. I've had the same set of 357 batteries installed in an HP-15C for about that long.
In 1997, I found two "new" HP-42S units that had been sitting unsold on the shelf at University of Alabama Huntsville's student bookstore since 1993, judging from their 3328S serial numbers. I bought both, and found no damage from the dead four-year-old batteries. But apparently, the Pioneers are not as frugal in standby current draw as are the Voyagers.
