The Collegiate doesn't look like a calculator developed by Texas Instruments.
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.
Even the internal construction of the calculator keeps the secret of the manufacturer.
Running Mike Sebastian's "Calculator forensics" gives a common result of 8.99999863704. We know this number from a lot of Toshiba calculator chips.
In other countries an identical calculator was distributed as SC-10 while Radio Shack sold the very similiar EC-4025.
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.
