With the Financial Investment Analyst FIA-10 and the Business Edge introduced Texas Instruments in 1989 two exceptional Financial calculators. Compared with the former Business Analyst BA-II the FIA-10 uses a huge, alphanumerical display and separate function keys to interact with the user. In most calculations all results and variables are visible simultaneously and like a spreadsheet on the personal computer you can change one value and observe the new results. In fact the FIA-10 is based on internal spreadsheet calculations called worksheets and uses a 8-bit hardware architecture similar to the TI-74 Basicalc and TI-95 Procalc instead the traditional 4-bit calculator chips of a BA-54.
The hardware is based on a 8-bit
microcomputer supported by a 2k*8 RAM (Toshiba TC5518), 32k*8 OTP-EPROM (Toshiba
TC54256) and a
LCD-controller (Sharp LH5821). The same hardware architecture with increased RAM and a
changed program in the ROM was used with the Fixed Income
The software of the FIA-10 supports 10 different worksheets to solve specific types of problems:
|WS||Title and function of the worksheet|
|#1||The Time Value of Money / Amortization worksheet analyzes equal cash flows, such as annuities, and generates an amortization schedule.|
|#2||The Cash Flow worksheet analyzes unequal cash flows; the worksheet calculates net present value, net future value, and internal rate of return.|
|#3||The Bond Calculations worksheet calculates yield and price of a bond.|
|#4||The Depreciation worksheet lets you generate a depreciation schedule using one of several depreciation methods.|
|#5||The Statistics worksheet performs statistical analyses on one-variable and two-variable data, including linear regression models.|
|#6||The Interest Conversions worksheet converts interest rates between annual percentage rate (APR) and annual effective rate (AER).|
|#7||The Percent Change worksheet calculates the percent difference between two values.|
|#8||The Profit Calculation worksheet calculates cost, selling price, margin, or markup.|
|#9||The Date Calculation worksheet finds the number of days between two dates, or finds a date that is a specified number of days from a given date.|
|#10||The Memory worksheet provides a visible storage area for as many as 10 values. You can display five of the values at a time.|
The FIA-10 could be called the missing link between traditional, line orientated calculators like the BA-II Plus and the new Graphing calculators started with the TI-81.
If you are interested in the Flight calculators (avstar, prostar) manufactured by Texas Instruments for Jeppesen Sanderson, Inc. you'll ask: Why no product based on this FIA-10 ? The huge display and the function keys would give a perfect product. Jeppesen Sanderson was indeed inspired from the FIA-10 but the product was developed elsewhere. View the wonderful result here.
