RE: New HP calculator literature site
When you examine the TPPT words, you'll quickly discover that this package is directly derived from the Forth words provided in section 21, "Forth Utilities" in the the "HP-71 Software Developers' Handbook", which is a seminal and essential guide to learning to use Forth on the 71. Though I had never dabbled in Forth before the 71 (and so leaned on "Learning Forth") the nibble-based implementation is different in a lot of ways from Forth-83, and examining the source for the new words in the Forth Utilities sheds a lot of light. Similarly, when exploring the new words in TPPT, the analogous source files are very helpful.
