Do you have a pointer to something that describes this better?  I've
been unable to find any info at all on the 7100LC and the 7300 is
described mainly as a 7100LC core.

I wouldn't mind playing with the machine description some.  Also, do you
have any clue if the 8000 also has this same asymmetric ALU situation?
