Differences between the HP 15c CE and the original HP-15C

[Gene]

Couple of additional notes that I will add to the top post.

This list is not "my" list. Much of it is in the actual HP-15C CE manual itself and several people here helped with reviewing the write-up of this list.

"Synthetics" on the HP-15C original fall into what PPC termed NOMAS (Not Manufacturer Supported) and were never core functionality in any way described in the original manual. As Jose called them, they were a "trick" and that trick is not present in the HP-15C CE.

And FYI - one of the longer running programs for the HP-15C, Valentin's e to 208 places, takes about 20.5 seconds with the PSE instruction removed on the HP-15C CE.
