Full name is TI-74 BASICALC. Very nice tool. And I say tool, because the TI-74 is not just a calculator. It comes with an industry strength plasic cover, and the whole thing feel heavy and strong. It's an engineering tool, not just a calculator.
Programming the TI-74 is easy, especially if you have some familiarity with BASIC. If you prefer Pascal, there is an optional Learn Pascal ROM module that has a very nice Pascal interpreter. Documentation is exellent, both for the calculator itself as for the modules and peripherals.
The performance index
listed in the specs above was calculated in the default BASIC programming mode of the TI-74. I also own the Learn Pascal module, so I thought it interesting to see if performance differed when using that. I used the following program to measure the performance:
100 PROGRAM perf;
110 VAR w,i:INTEGER; x:REAL;
120 FOR w:=1 TO 10 DO
140 FOR i:=1 TO 10 DO
230 END (* i *)
280 END (* w *)
It turned out that the performance index when using Pascal comes to 20. Slightly less than the default BASIC value. Not surprising really, as there is probably some overhead from the translation from Pascal to native code.
Mode Time P.Index
BASIC 12.5s 27.2
PASCAL 16.6s 20.5
For reference, here is the listing of the BASIC program I used:
100 FOR w=1 TO 10
110 FOR i=1 TO 10
250 PRINT x
Successor to the CC-40?
According to some sources
, the TI-74 may be considered the successor to the legendary Texas Instruments CC-40
