Texas Instruments 5TI - The Vintage Technology Association Texas Instruments 5TI Written by Accutron on 2006-11-24 Devices included in this entry: Texas Instruments 5TI-1032-1 Sequencer Texas Instruments 5TI-2001 Programmer (pictured in thumbnail) The Texas Instruments 5TI is a compact TTL-driven programmable logic controller, designed for industrial automation. A basic system consists of a 5TI-1032 series sequencer, and a 5TI-2000 series programmer. The 5TI-2001 programmer is a handheld interface for the 5TI-1032-1 sequencer. It allows the operator to temporarily interface with the sequencer and enter program steps. This device does not have a power switch or any provision for using line or battery power; it receives its power from the sequencer, through a permanently attached interface cable. The case of the 5TI is the same as that of the SR-20 scientific calculator, desktop companion of the SR-10 pictured above.

However, its similarities to the SR-20 are superficial. The 5TI programmer is built from discrete TTL, implementing 39 TTL ICs in the programmer, and another 39 TTL, static RAM and UV-EPROM ICs in the sequencer itself.

The display is a Burroughs Panaplex II with 10+2 digits, similar to the displays used in various TI desktop calculators from the same era. 5TI system, includng the 5TI-1032-1 sequencer and 5TI-2001 programmer. 5TI-2001 programmer, serial number 83040183.
