  • From Centre For Computing History:
  • The TI-92 programmable graphing calculator was released in 1995. It was the first symbolic calculator made by Texas Instruments. A symbolic calculator is one that has a computer algebra system (CAS) and is capable of producing symbolic results. The TI-92 came with a computer algebra system (CAS) based on Derive and geometry based on Cabri II. It was one of the first calculators to offer 3D graphing.
  • The TI-92 was based on the Motorola 68000 microprocessor, and featured 128K of RAM, including 70K user memory. The calculator featured a full QWERTY keyboard, however this resulted in it not being allowed in many standardised tests in the USA. It was powered by four AA batteries, with a lithium backup battery.
