And the best evidence that the 6809 was more expensive yet -- a 1981 
price list of two similar boards, one with the 6502 priced at $239, and 
one with a 6809 priced at $359, a $120 difference. I do understand that 
support chip price also affects the cost of the board -- the Motorola 
support chips would be more costly than those needed for a 6502 also.
