[Coco] What's the Motorola M68MM19?

[billg999 at cs.uofs.edu]

Obviously that is of little use without the motherboard/buss
it plugs into.  But, does anyone know of any 6809 single board
computers that might still be available?  I like my COCO, but
I like bare 6809's as well.  I know there are even some new
systems for the Z80 (P112) but are there any for the 6809?
