Still haven’t learned how to program your Apple II in its native language?  Maybe this “tiny ebook” is just what you need to get started.  Author Nick Morgan writes:

In this tiny ebook I’m going to show you how to get started writing 6502 assembly language. The 6502 processor was massive in the seventies and eighties, powering famous computers like the BBC Micro, Atari 2600, Commodore 64, and the Nintendo Entertainment System. Bender in Futurama has a 6502 processor for a brain. Even the Terminator was programmed in 6502.

From Daniel’s comp.sys.apple2 post:

I wrote a forth style Apple II cross assembler:

http://krue.net/sixtyfive/

sixtyfive is a forth style assembler. It’s only been tested with gforth, but I’m open to adding support for others if it’s not too much trouble.

sixtyfive supports 6502, 65c02, and 65c816 opcodes.
sixtyfive can output a limited set of OMF files.
sixtyfive can compile resource definitions.
sixtyfive can make ToolBox calls (they’re not all added yet though).
sixtyfive can output ProDOS disk images.
