Component files

appleII.asd - The system definition. 
circular-sequence.lisp - Code to support various operations on circular sequences, including a naive search for a subsequence. This is useful to deal with emulated disk track images, which are circular in real life. 
disasm6502.lisp - Basic 6502 disassembly 
disasm6502-oo.lisp - Support for symbolic disassembly, including auto-generated labels, screen and high-bit ASCII text, and hex data dump sections. 
nibimage.lisp - Code to deal with NIB binary disk images, extracting the de-nibblized data sectors. 
dskimage.lisp - Code to deal with normalized Apple DOS 3.3 or ProDOS disk images, extracting various files from the DOS images. 
applesoft.lisp - Code to de-tokenize binary format AppleSoft BASIC programs. 
diskcopy_image.lisp - Basic support to read Prodos images in DiskCopy 4.2 format 
asm6502.lisp - Beginnings of a Lisp-syntax 6502 assembly language. Couldn't figure out a simply way to handle symbolic math and instruction length variations, including forward-referenced labels.
