I picked up a number of electrical & computer engineering books at the 
thrift shop today.  The one of most interest to this group is the original 
Motorola MC6809-MC6809E Microprocessor Programming Manual printed in 1981.



In the I did not know that department; on page 1-2 a Memory Management Unit 
(MMU), the MC6829 is mentioned as having the ability to access a two 
megabyte memory space.  This at a time when four kilobytes was standard for 
our CoCo!
