Cross Assembler for UNIX V.3

[Jo Poplawski]

Does anyone out there know if there is a good cross assembler for UNIX V.3?
Basically what I need is the ability to write my 6502 assembler routines on
my 386 box then use its power to assemble the program on it, then transfer
it to my Commodore 128. I would really prefer public domain though since it
is for my personal use and system, I can afford a *small* budget.

If you know of any such programs, please mail me and if there is enough of
a response, I will summarize results.

Thanks in advance.
