Hi

Im have alot of old Apple ][s and a few Commodores and i heard the 6502 was a great pro to learn assembly.

My problem is while i have alot of boxes, i dont havnt any books about assembly or anything usefull on the Apple Monitor(just how to load and get into the mini assembler).

Anyone point me to some useful info online? Telling me the few Apple specific now? Maybe recomend a book or 2 for me to look for on ebay(not many even have discriptons online now...).

Thanks

The Synertec programming manual for the NMOS 6502 is online at http://www.6502.org/datasheets/synertek_progman.pdf
For the Apple II monitor program, you may need to do a web search.

I have a bunch of apple programming books. Let me know which models you're looking to program on and I'll see which ones I can find would be best for you. It may take me a bit as I had to move some of my apple ][ stuff around to make space for my new engraver, but I will locate it as quickly as possible.

A good place to start is the A2-Web at:

http://www.wbwip.com/a2web/

The A2-Web has links to all sorts of Apple II information (there is a ton of it on-line). A lot of old Apple II software (including assemblers!) has been (re-)classified as freeware and can be freely downloaded, although it may take some effort to transfer downloaded software to the Apple.

In addition to the many fine 6502 books listed on this website, a number of Apple II-specific assembly books were published. A popular one was titled Assembly Lines: The Book. It was written by a former schoolteacher and was well-liked for its easygoing style.

If the Apple is going to be your 6502-based machine, you'll probably find that Apple's own technical reference manuals are helpful. These manuals contain information about, among other things, use of the built-in monitor program, the memory structure (this was insanely complex on the IIe), video memory, and ROM listings (except the IIgs). Note that there were several versions of ROM for each model and the ROM listing may not match what you have exactly. The manuals for the various models are:

Apple II Reference Manual (II, II+)
Apple IIe Technical Reference Manual (IIe)
Apple IIc Technical Reference Manual (IIc, not sure about the title)
Apple IIgs Firmware Reference (IIgs)
