The TI-3000 desktop calculator was first announced in April 1972 as Deskmath LP3500. Beginning June 1972 first customers got in the Neiman-Marcus and Sanger-Harris department stores in Dallas, TX their Deskmath LP3000 calculators before the formally introduction on September 21, 1972. Don't miss the transitional TI-3000 Deskmath.

The TI-3000 was introduced together with its sibling TI-3500 and the famous Datamath (TI-2500). With these calculators Texas Instruments started the business of selling calculators under their own brand. Find a reprint of the Press Release about the introduction here.

Keep your fingers away, normal voltage is about 150V. With their orange glow they give a perfect readability even in bright ambient situations. The keys give a perfect tactile feedback, a lot of the TI-3000 and TI-3500 are still in daily use.

The design of the TI-3000 was heavily influenced by the Canon L100A. Other calculators using the single-chip calculator technology introduced by Texas Instruments were the Canon L100S, Heathkit IC-2008, Radio Shack EC-1000 and Toshiba BC-0802. A different approach with more functionality was introduced with the Corvus 300E.
