The Complete Texas Instruments TI-1600 Line from 1976. These calculators were produced in an effort to slim down existing Texas Instruments calculators from "hand-held" to "pocket-sized". The main obstacle was the VFDs ran on 9V batteries. As such, Texas Instruments had to commission the French company SAFT to make custom 9v batteries. The circuit boards are shaped like a block-letter "C" to allow the battery to sit next to them to make the calculators as small as possible. This line was discontinued when Texas Instruments released their first LCD calculator, the Ti-1750, in 1977. The lower power consumption of LCD allowed for the use of smaller button cells, which allowed for calculators even slimmer than the Ti-1600 line. None of these are working. They may not be able to draw enough power from only the adaptor, and the custom batteries are long dead. There may also have been battery leakage.
