The past six months have seen many fickle Casio fans turning their efforts eyes and money towards a new calculator, the TI-84C.
Why this calculator is no better than any other casio rejects (aka, TI calcs):
- The 84+CSE has only 21KB of user RAM. While there are 128KB available for assembly programmers, TI-Basic users and such are stuck with even less RAM than before. The Casio PRIZM, on the other hand, has approx. 50KB of RAM, plus 16MB of storage space.
- The 15MHz z80 processor. Much slower than the PRIZM’s SH-4A (58MHz). Remember that we’re dealing with color here, and 15MHz just doesn’t cut it.
- The screen is capable of 16-bit color, but the calculator itself isn’t. Refreshing the whole screen once with just 8-bit color takes 2 seconds. This is unacceptable.
- The lack of a good C compiler. At this point there is no way to program in anything other than BASIC or Assembly. The PRIZM comes with support for C, native support for BASIC, and third-party languages like LuaZM.
In reviewing this calculator, we are forced to realize that this is nothing more than another over-priced, under-powered, excuse for a calculator from who else but, Texas Instruments.
