Source code resources?

[Synthead]

So I'm reading Andew's tutorials and picking through the Stella manual, and I'm getting into writing code and compiling stuff. However ... I only know a few very simple commands - only the ones in the tutorials that I picked up on. I'm not sure if I'm supposed to know the commands already ... I'm a bit confused. So I'm wondering - is there's a resource out there that defines all of the existing commands for this stuff? Cause I'm kinda left in the dust here ...

 

I used to program in BASIC for Apple ][ //e and Tandy computers, as well as modern TI graphing calculators. So I have a true feel for programming and stuff, but this is pretty much my only area of expertise ... if only I could read through commands and syntaxes ...

What you need is a general tutorial for the 65xx series chipset...and those can be found at http://www.atariarchives.org/ (machine-specific tutorials are still in the 2600 For Newbies and Porgramming 101 forums).

BTW since you've programmed in Basic, give Machine Language For Beginners a try (which applies a working knowledge of Basic toward learning assembly). To experiment, you can use the Atari800Win emulator to practice on...use F8 to enter it's monitor mode.

have a look at

 

http://www.6502.org/tutorials/

 

especially

 

http://www.6502.org/tutorials/6502opcodes.htm

 

(this is not a tutorial, but an opcode list, with a fairly detailed explanation of each opcode)
