How many MHz and RAM in a standard maths calculator?

What kind of calculator? Scientific, graphical etc? These things probably vary depending on the make and model of your calculator so there is no universal answer.

.16~.32mhz depending on functionality as for ram 640k is the average.

One of the best known graphing calculators is the TI-83.

Here is some good technical information on it. I know it's a little more than what you're looking for but it gives you a good idea on the ins and outs of this particular calculator.

Thanks everybody,
What OS do they use?
Can you install a different os?

Do they sell little cheap 1 - 8MHz etc micro computer to mess about with?
Thanks,
John.

First off with the question you are asking you clearly are way over you head to even try stuff like that. Big time considering you are asking question like what chips or OS they use on a TI.

TI makes the chips for TI cals. It is TI OS and yes you can install a different OS on them not that I recommend you doing that.

Oh and yes you can buy the chips from TI.

Do you require some kind of microcontroller for a project? Why are you asking about calculator electronics when they're probably not going to solve your problem?

Miles looking at the questions he has been asking he is going to be WAY WAY over his head in getting electronics if he wants to buy the chips.
 
Not sure what it is you want to do, but you might want to look into something like the Arduino. It's a microcontroller platform that's very popular and that's very easy to use. On top of that, you just code it in a c/c++ like language, which is much easier than most native languages on other platforms. It's fairly cheap, about 30$ for the platform and about 3 to 5$ for each additional microcontroller.
 
For basic good chips to mess around with, why not look into something like the pic16f88? They are quite capable and you can get free samples of these chips too

Do your prices include the compiler hardware? If so, I may look into that

30$ is the prototyping platform/hardware pcb (actually, you could program it with a serial connection straight to the microcontroller without the board, I believe). You just plug it via USB, download the software on your computer and you're good to go. http://arduino.cc/en/Main/ArduinoBoardUno

I'm not sure what you mean by compiler hardware or if it applies to the Arduino. Everything is open sourced so there's no licensing involved.

Interesting. Will look into that as it would be fun to mess around with

What I was referring to was the hardware required to program the chip (interface with computer) and I looked into those kits and it is taken care of via USB as you had mentioned:)
