.. very close. Apparently there was a process
difference.
Though intel did at times morph one part/process
into another.
According to the 1980 Component Data Catalog, the specifications for
the 3205 (p. 2-22) and 8205 (p. 6-45) are identical. DC, AC, and all
the graphs.
By 1980 intel was shifting to mos/Hmos/HmosII and by then those
parts were way down the the process scaling and 32xx were nearly
extinct. In 76, that was not the case. Keep in mind my comment that
intel did morph parts into one another.
