What is this?
In the first three months of 1979 BYTE magazine published a series of articles describing the brand new microprocessor: the 6809. Written by the co-designers of the 6809, these articles are a fascinating trip down memory lane. Terry Ritter and Joel Boney go to great lengths to justify the design decisions made during the creation of the microprocessor.

Why did I reproduce it?
It is extremely interesting. Anyone who as worked with the 6809, or any other microprocessors of that generation will enjoy this work. In the third article the 6809 designers list several features missing and the reasons why they were not implemented. Almost every one of those features were put into the Hitachi 6309 part.
