I guess the answer is that the Harvard Architecture was put out as an abstract concept. As with all abstract concepts, some engineer has to make it work in the "real world". In this case it would have taken probably 100 pins or more to package the 8051/52 family as a true Harvard Architecture device. It would not have been cost effective for the market that Intel was targetting for this device, they already had the higher cost 80x86 market. So with the cost constraints and the abstract concept was born the 8051/52 family. I don't about the rest of you guys, but this chip continually amazes me at what it can do, considering it is only an 8 bit chip!
