(Not sure if this is the right forum to post this in?)

I’m doing a second showing of my pretty large (100+ out of 250 items) and pretty cool 1970s-era calculator collection in Portland OR, August 18-20. If you are in the vicinity, please email me (via the contact info on the site below) and stop by!

Interesting. I always wanted a TI-SR 22. Only calculator that I knew of to do fractional hexadecimal math until I found an app for a PalmPilot that did the same. Haven't found any app for Android that does the same.
The HP 16C could do that after a fashion. The example in the manual presents a program that can translate from decimal floating to IEEE binary floating point. Forget the details, however.
