Info: We wrote May 1982 when Texas Instruments printed the sales brochures of the TI-88 on glossy paper. The brochures promised the introduction of the TI-58C/TI-59 successor for Forth Quarter 1982 in a package matching the TI-55-II line - before we got word of the TI-66. Today we know more: The development of the TI-88 was finalized, the manuals printed, the first pre-production calculators worked perfectly and Texas Instruments canceled the whole project! Maybe one of the reasons was the introduction of the powerful Hewlett-Packard HP-41C calculator or the innovative Sharp PC-1211 Pocket Computer. Or the underestimated complexity of the TI-88 design. Or electrostatic discharge (ESD) issues of the Module contacts. Or the internal competition with the CC 40 Compact Computer. Or the keyboard problems encountered with the TI-55-II family of calculators. Or the decision of a Manager of TI's Consumer Electronic group to quit the calculator business...

The PC-800 Printer is a dot-matrix thermal printer designed for use with the TI-88 Programmable. It connects to the TI-88 through a 2-pin Peripheral I/O connector. A second Peripheral I/O connector on the back of the PC-800 allows to connect another device like the CA-800 Cassette Interface to the TI-88.

Info: Texas Instruments announced on March 8, 2010 the new TI-Nspire CAS Touchpad and TI-Nspire Touchpad graphing calculators. In the United States the new calculator was listed on the TI website as a complement to the TI-Nspire CAS with Clickpad while in some other countries, e.g. Germany, the calculator was introduced as successor to the previous model. The new Operating System 2.0 and some internal labels on the PCBs (printed circuit boards) of the calculator suggest indeed the switch to a "TI-Nspire 2".
