6502.org

Hello,

I have the book "Machine Language for Beginners" by Richard Mansfield and would like to learn 6502 assembly.
The problem I'm having is the simple assembler program which is listed in the book takes a long time to enter into my apple and doesn't even work.

I don't know ( and don't really want to know ) enough about basic to correct the errors.
Has anyone here has read this book and used a different assembler?

Thanks for any information you can provide.

Do you have a disk labeled the DOS Tool Kit? If so, there is a disk-based assembler called EDASM.

I haven't read the book mentioned, but for an assembler that will run on an Apple, there are at least two now-freely available Apple II assemblers: the S-C assembler, and the Lisa (the name doesn't refer to the pre-Macintosh computer of that name) assembler. Both were commerical products at one time, so both are quite usable. You can download the assemblers and documentation at:

Other popular Apple II assemblers include:

EDASM (the tool kit assembler)
Merlin (Big Mac)
ORCA/M (APW)

You could try eBay or something for these. There are versions of Merlin, ORCA/M and the S-C assembler that can assemble 65816 code also. There were several versions of all 5 assemblers, intended for different machines and operating systems, so you'll have to find one that matches whatever you've got.

It can be convenient to have an assembler that runs on the 6502, rather than using cross-assembler, especially when debugging. Most Apple assemblers were written for 5.25" disks, so finding disks to save your work on could be an adventure.

Good luck.

I couldn't find a dos toolkit disk but I found one with Lisa on it.
Thanks everyone for your help.
