The SC-10, a.k.a. Collegiate, doesn't look like a calculator developed by Texas Instruments.

SC10_1.jpg (82809 Byte)The calculator uses a remarkable foldable keyboard with two different function layers.  You can either view the 15 built-in constants and 30 English-Metric conversions or the Two-variable statistics.

Running Mike Sebastian's "Calculator forensics" gives a common result of
8.99999863704. We know this number from a lot of Toshiba calculator chips.


A very similar calculator was sold under the label of Radio Shack. Compare the SC-10 with the EC-4025 and explore the battery access of the calculators.

Don't miss the Personal Banker, one of the best calculators developed ever.

Interested in foldable calculators? Canon introduced already in 1980 with the Canon card F-72 a remarkable product.
