First non-HP pocket calculator with scientific functions ?

[Gene]

The Rockwell appeared in late 1973, so it now depends on who came first - Rockwell or the Sharp!

I got this information from newspaper ads and did not have many sharp calculator ads from which to gather info.

I do not think the 2nd place belonged to the TI SR-50 which I did think for a long time.

Now apparently either Rockwell or the Sharp!
