Kevin,

The source that I found for HD6309 microprocessors is:

Marshall Electronics 2045 Chenault Dr. Carrollton, Tx  75006

(214) 233-5200

I called them yesterday (Thursday), and the guy that I talked to said that they
did in fact carry them, but were currently out of stock.  However, he added
that it looked like a new supply was coming in in a couple of weeks.

I guess if you wanted to order a few, then you'd just be backordered for a
little bit.

I went over there today and picked up a data book that includes most, if not
all, of Hitachi's 8/16 bit microprocessors.  The book's in the car now, but I
seem to remember that there were 6301s through 6809s (which includes the 63B09,
63C09, 63B09E and 63C09E microprocessors).  And Hirotsugu was right on in his
"Secret Feature Memo", the new features are not documented in the data book. 
It looks like they just took the MC6809 specs and retitled the document for the
6309.  I'm going to call Hitachi America to see if they now have official (or
at least "semi-official) specs written for the heretofore secret 6309 features.

The data book that I got today also included some MC68000 counterparts, too.

I wonder of some of them have "secret" features, too, that could blow the doors
off stock 68000 operations.   Hmmmm....

Lee
