The famous TI-2500 Datamath calculator was first announced in April 1972 together with the Deskmath LP3500 desktop model. Find a reprint of the Press Release about the introduction here. Beginning June 1972 first customers got in the Neiman-Marcus and Sanger-Harris department stores in Dallas, TX both the TI-2500 and the rare Deskmath LP3000 before the formally introduction on September 21, 1972.

In September 1972 the nameplates of the desktop models changed to the more common TI-3000 and TI-3500 designations. Unfortunately the "Deskmath" nickname disappeared. 

We recently acquired this transitional TI-3000 Deskmath sporting already the new color scheme and lettering of the TI-3000 but still using the old housing with the LP3000 Deskmath label.

To our current knowledge only few (about 1000) Deskmath calculators were produced between May 1972 and August 1972 in a beige housing. For the later mass production a slightly darker color was chosen.
