Just a heads-up: MSD8X and USBDRV8X do work on newer calcs, though they have limited functioning.

Pimath: it happens much more, I also have them but they're more about stuff thats further away in future. It sometimes saves me from stupid mistakes that I do make in my dreams.
(True Story)

What do you exactly want to do? If you want to automate certain things, Nspire basic is the way to go.

*tutorial alert*

Basically you open up a new document and save it in the MyLib folder (only if you want to access the program/function from other places). Next up is opening your Program Editor; this is done by [menu][9][1][1]. Next up, type in the name of the program and set the type: Do you want it to be a function or a program?
A function is good for almost any long calculation you want to automate, e.g. calcualte the gravity at a certain distance above earth. It returns the last value that it got, a.k.a. the "Ans" variable. A function can be used from anywhere. A program is for your more sophisticated stuff where you need user input during your program.
Next up, library access. I always set this to public so it comes into the catalog. This is really useful when you want to use your programs in the Scratchpad or in other documents, so set it. (you can change it afterward though)
After this, the program editor pops up.
Now what? Well, you see 2 things: your usual calculator window, and the program editor. How surprising. In the program editor part, you can edit 2 parts: the arguments that are passed to the program, and the program itself. In the arguments part, place the names of the variables you want the user to pass to the program when he calls it (this is the only way of passing values to a function by the way).
Now, if you click at the part between func... endfunc and prgm...endprgm, you can edit it. If you press [menu], a nice menu pops up with categories for commands you can use. You can use this menu while programming, but I recommend just using the (however small) keyboard.
Math and stuff works the same as in the calculator so I won't explain that. And because math is the only thing you can do with Nspire basic, this is the end of the tutorial.
If you want to know stuff, Stefan (in the post under this one) linked to [tibd=nspire]this[/tibd] TI-Basic Developer page, which is really useful.
For other questions, we're happy to answer them!
also peanuts:

Well the work scheme I have now is send file to calc > ctrl-c -> go to folder -> ctrl-v -> delete other file

You indeed do not really need input for getting input into your program. You can also write your own input routine.
Not that I ever needed to, though.

That's true

Link to an installing tutorial. I just need that.

Just follow the readme instructions and you should be fine I think.
