Sales of the TI-57 started in July, and in August for the TI-58 and 59 (as we will see next month). <br/><br/> It will become the most sold programmable calculator in the world. Though inexpensive ($80), the TI-57 is a technological prowess. It is the only programmable calculator with all functions centralized in a single integrated circuit. <br/><br/> A low consumption MOS/LSI circuit does the work of 30,000 transistors. It features a 4 bits microprocessor, 50 program steps in RAM and a ROM command software. A new coding method allows to save in one programming step up to three keys entries (as in : Inv-2nd-cos). <br/><br/> All these characteristics are largely inspired by Hewlett Packard's latest products, HP being Texas Instrument's largest competitor in this area. <br/><br/> The TI-57 will also be sold through <b>Radio Shack</b> under the name of <b>EC-4000</b>.<br/> TI-57 production will end in 1982. <br/><br/></p><img src="/media/history/images/texas_ti57_ic_1.jpg"/>
