Also, I'm working on CPU code for a Polish notation parser which is essentially a Lisp parser. And then you can be like "RARARARARARA."

Also, RPN is clearly the best way for a calculator to work. An RPN calculator is essentially an exercise in stack manipulation. I should make a CPU program for an RPN calculator using the wired keyboard.

Oh, nevermind.. *Brainfart*

You could have just said to make one of these lol: http://upload.wikimedia.org/wikipedia/commons/0/0d/Texas_Instruments_TI-89.jpg

Would be pretty cool to see one though.

RPN is much easier to work with, as the logic is like this:

loop:
  if number then push onto stack
  if operator call the appropriate function which will pop the two most recent ones on the stack and push the result.

EDIT: I'm now working on a register-based calculator in E2.

That's what I mean, then

Making a fully-functional TI-89 would be madness. Here's a nice picture of the register-based calculator I made.

(click to go to the album page, it has a picture of the back too)

I also tried to add storing to a RAM gate so you could have 64 variables available, but the Wirelink's code is a bit rubbish for hi-speed stuff.

...Wait, I just thought of a possible workaround. Yeah, this should work. BRB, off to the moon.

Wickedly awesome job AzrealUK

I agree about the T-89's madness -- but *that's* the challenge, muahaha

(remember, qualifications are listed in main post, it doesn't have to be just like the TI-89 [for those of you who are wondering heh])

Gj, anyone else?

[robertark]

Oh ps: is there anyone else workin' on this

[AzraelUK]

Thanks, Robertark I might try making an RPN calculator with the CPU due to its inbuilt stack. I'd do it with E2 but hispeed wirelinks seem to be broken.

Someone should start with the TI-10 and keep going up the progression until they can't anymore

[quantumdude]

Heh, this might be easy for me, because I've got the source code of a java version of the windows calculator (well, it's got most of the functions - the rest I can just figure out)

EDIT: making a TI-89 wouldn't be THAT hard - you've got the wire CPU, now you just have to rewrite the TIOS :P
