Or, if you don't want to spend any money, send me e-mail and I will send
you a version of a 1-pass 6502 assembler that is written for unix machines
(it compiles on the Mac under Think C, but needs a little tweaking to make
sure that the arguments passed to malloc() are longs not ints).

It is pretty fast, supports huge labels and the following pseudo ops:
.or	set origin or program
.eq	constant definition
.as	ascii string
.hs	hex string
.bs	block storage

Any label reference can include a positive or negative displacement.

Generates 2 completely non-standard formats because I had no idea of what
the standards were, but they're E-Z to translate.

Generates a symbol table, error messages, etc.

Since you get the source, you can dick around with this as much as you want.

Also, if you so choose, you can get my 6502 interpretter which does an
instruction for instruction interpretation of a 6502 processor with a really
gross command-line interface, and a pretty primitive monitor.  It can read
(guess what?) both of the file formats generated by my assembler.  It also
has hooks to get into the operating system by reserving addresses $F000-FFFF
as traps.  Doing a JSR or JMP to these addreses executes an IO function.
I have a demo that acts like "cat".

Free for both.
