Ok, so first was an Apple II+. This project was the first computer I ever designed and built chips up. Ironically it was based on a 68K processor and was basically a 1984 128K Macintosh, albeit one with much simpler ROMs.
Fall quarter of 98 I took EE478. It is the Electrical Engineering departments Capstone digital design course. It is the course tries to identify and fill in any holes that graduating EEs may have. It tries to do this through a series of rather large labs and one final baloon design project at the end of the course.
