Texas Instruments introduced in 1988 a revolutionary concept: The TI-2800 Paperless Printer! The calculator works like the known printing desktops e.g. the TI-5010. All calculations are done on the main display. Instead the usual printout on a paper the results are scrolled through a secondary display with 6 lines. A maximum of 99 lines could be stored and scrolled up and down with the arrow keys.
Compared with a simple desktop calculator the internal construction of the Paperless Printer was much more difficult. In both shells of the housing a huge, double side printed circuit board was integrated.
The TI-2800 Paperless Printer was soon replaced with the TI-5038. A big step in cost reduction was achieved with the TI-5028.
Texas Instruments launched in 1987 a very innovative product line with the TI-2400 Phone Bank, TI-2600 Personal Banker, TI-2700 Mini Data Bank, and TI-2800 Paperless Printer followed till 1990 with the TI-2100 Pocket Info, TI-2900 Info Bank, TI-3100 Pocket Dialer, TI-3200 Pro Dialer, and TI-3400 Europa.
Don't miss the TI-2300 introduced in 1988.
If you know the history of Texas Instruments it seems to commemorate the introduction of the TI-2500 Datamath a quarter century ago.
