I am looking for a decent assembler and/or simulator for 6502/Apple II/II+. I.e. something I can use for testing and debugging of my Apple II+ assembler programs. I guess I want a 6502 assembler plus an emulator which supports loading the full Apple ROM image into memory. A big plus would, of course, be emulation of Apple I/O like display, keyboard, etc.
What are the best choices? (I run windows xp on my PC)
