Calculator for electronic/firmware engineers

[Csaba Tizedes]

Yes, this is a HP forum, and yes, I am member here since end of the 90's, yes, I am using mainly HP calculators, but you know that, the TIs also can do it.

Check it and decide: EE Pro (TI)

TI-89 can handle units? Yes.
Hex support? Yes.
The other conversions? I guess, yes - these are typically common for graphing units. As I can remember the word length 32 bits and can not set. Bitwise operations, shift and rotate also available. The HP I guess more advanced in this field - but must to check the requirements and do not forget, you can define your own functions...

Check the available programs eg. here: TI-89 Programs - maybe you can find interesting stuffs.

And the main question: the cost (from eBay) of a Prime is approx USD 120-150, a TI-89 Titanium is approx USD 50. I think, there is no question.

BTW: your nick is kuro68k. Maybe this is not a coincidence: TI-89 series (assembled with Motorola 68k processors)
