Re: Found a SR-10!
My father purchased one of these machines back in '74. I remember it
quite well. The CD is a Clear Display key. If you input an incorrect
number you can press the CD key and then key in the correct data.
The EE key is the scientific notation key.
The X squared key is the ... number squared key.
Any other questions regarding this calc model feel free to write.
