When Should We Teach Microprocessors?

We all agree that tomorrow's engineer must have a working knowledge of microprocessors/microcomputers, especially as related to a myriad of applications. But there appear to be two schools of thought on how this should be done. Spokesmen for these schools might state their positions as follows: (A) We have a real opportunity to teach the subject to freshmen, making use of it to motivate students and give them engineering early. Such working knowledge will make it easier to understand later courses in operating systems, computer architecture, computer languages. (B) Sure, housewives and grade school kids can understand microprocessors, but our engineers deserve better. Give the EE's a strong background in computer fundamentals, and then show them the beauty and simplicity of the microprocessor when they can really understand it. Besides, the make-shift and sloppy ideas and techniques introduced in a "baby " source will surely inhibit a strong educational program which is to come later. What do you recommend?
