I know there’s at least one other hp one. I don’t think i have it though. Im currently digging through all his engineering stuff i saved from being thrown away.

I'm REALLY Waiting for the HP42 Advanced Anniversary Edition since that is the one that really kicks ass while being normal calculator size instead of the HP-48/TI-89 big brick size. |

Using the logarithm identity to shorten the division to subtraction would only add more pairs of parenthesis on the TI-89 resulting in a net gain of keystrokes. |
