Hi,

There are two shareware cross assemblers available on the PC SIG
disk collection and/or CD ROM.  They are TASM and XASM.  Both run
on PC compatibles.

I tried out TASM, and compiled one program for a 6502 based single
board computer project I am putting together.  I beleive that TASM
is going to be able to do the job well.   The shareware fee is
extremely reasonable, at only $30; it's put out by a company called
Speech Systems.  TASM has a very nice macro facility,
#define/#ifdef, and #include.  The neat part is that you can put
together your own token table for the instructions for the CPU you
happen to be using.  I think you get 6502, 6805, and 8041 tables
with it.  TASM is a two pass assembler.  It compiled my 110 line
check-out program in about 15 sec. on an 8 MHz AT clone.  TASM also
was able to assemble APPLE II EDASM programs with only minor
changes.  The directives in TASM all begin with ., while in EDASM
directives are plain words.  A quick global replace with MKS
Toolkit's vi fixed 'em right up.  The docs that come with the PC
sig release state that Unix/MSDOS c language source is available.
It sounds like it should compile in just about any environment, as
the authors went to pains to avoid using any machine/compiler
dependent library functions.

PC SIG also has XASM, but I didn't bother to look it over since
TASM looked just right for what I wanted.  On cursory examination,
it looked like TASM was a more thorough production.
