Map "Alternate" to "Compose" on Sun 3 keyboard?

[Bob Weissman]

Environment:
	Sun 4/110 with cg4 frame buffer
	SunOS 4.0.3
	Type 3 keyboard
	Open Windows 2.0

Since the Type 3 keyboard has no "Compose" key, I would like to get the
same effect with the "Alternate" key.

I can't figure out how to get "xmodmap" to accomplish this.  It seems that
the "Alternate" key is unknown to "xmodmap".

Can anyone help?

Thanks,
Bob Weissman
