...and you answer "Because the two types of memory are separated" and they ask, "But why?" The answer is pretty obvious when you're looking at three chips (CPU, XRAM, EPROM), and it's even obvious why the same architecture is maintained within a single chip when you know how it got there.
..."because its a Harvard architecture not a Von Neumann architecture". Then you stand back, look smug for an instant, then say "its all in your notes isn't it ?"
....it doesn't seem unreasonable that someone learning the 8052 should have some idea of the legacy devices and where it all came from.

Its one thing to appreciate history, its quite another to have to re-enact it !
It seems to me it would let the users better appreciate the parts available today and at the same time understand how the architecutre got to where it did.
...but unless Gary makes the point strongly in his notes (which are too limited yet to comment on), and he admits to being a software guy, that this IS old hardware, they won't realise and my original point still applies.
