TI-501SV_P1.jpg (397698 Byte)The TI-501 introduced in 1999 morphed without any changes in the 21th century into the TI-501SV. It is still the synonym of a very cheap basic calculator. Selling price in the year 2009 was about US$ 3. If you search a somewhat larger calculator you would find it with the TI-503SV.

The internal construction looks very familiar to us and seems to be identical with the original TI-501 introduced 10 years earlier.

Don't miss the first TI-501 introduced already in 1982.
