The 65802 is manufactured by Western Design Center.

The address I have for them is:

        The Western Design Center, Inc.
        2166 East Brown Road
        Mesa, AZ  85203
        (602) 962-4545

(That should also answer someone else's question about how to contact them for
info on the 65816, also.)

As far as which assemblers support the instruction set, you've got several
choices: Merlin and the S-C assemblers both support it directly.  In general,
any assembler supporting the 65816 instruction set could be used, but wouldn't
"restrict" you to 65802 instructions, which might cause you some problems.

If your current assembler permits macros, you could also write a few to deal
with the 65802 instructions, and you can always "manually" plug in the 65802
instructions to any assembler.  The effort involved in both of those would
quickly convince you to change assemblers, I think, but hey -- it's a "cheap"
way to go.

You should be able to get the data sheet on the chip from WDC, which would
give you a complete list of the instruction set.  If you can't get it any
other way, drop me a note and I'll dig out the info and send it to you.

I =know= there is at least one person reading this group who's using a 65802,
and perhaps he'll answer your questions concerning usage.
