The TI-82 graphing calculator made by Texas Instruments. The TI-82 was designed in xxxx as a stripped down, more user friendly version of the TI-85, and as a replacement for the TI-81. It was the direct predecessor of the TI-83. It shares with the TI-85 a 6 MHz Zilog Z80 microprocessor. Like the TI-81, the TI-82 features a 96x64 pixel display, and the core feature set of the TI-81 with many new features. The TI-82 is powered by the same processor that powered its cousin, the TI-85, a 6 MHzZilog Z80 microprocessor.[1] This was an improvement over the TI-81's 2 MHz Z80 processor. In addition, the available RAM was increased more than tenfold ? from xxxxbytes to xxxx4 bytes (slightly more than the TI-85). Some of the more notable improvements of the TI-82 over the TI-81 include the following: the addition of a link port to enable programs and other data to be transferred between two calculators or between a calculator and a computer; the addition of two new graphing types ? polar and sequence, the addition of a new type of data ? the list, the expansion of the size limit of matrices to 50x50, and the (unintentional) addition of the ability to program the calculator in assembly language. The last of these provided a significant boost in interest in the programmability of the calculator, as the use of assembly language (as opposed to Texas Instruments' own TI-BASIC) enabled significantly more performance and flexibility with the programs able to be used on the calculator. Carried over from the TI-81 is the TI-82's power source ? four AAA batteries and one CRxxxx or CRxxxx lithium backup battery (to ensure programs are kept when the AAA batteries are being changed).
Think about this? I believe that good used equipment will give you a much greater return on your initial investment. Let someone else take the depreciation from new. After you install the equipment and it is running, your customers and employees do not know the difference, your break-even point to pay for the equipment is substantially lower and you start making more money $$$$$$$, quicker.
