- That is how the term Harvard architecture is used today, but as
- Hennessy and Patterson discuss in Section 1.8 of their book CA:AQA,
- the term originated as a description for the Mark series of machines
- built at Harvard by Howard Aiken. These machines had "separate
- memories for instructions and data, ... [and they] were regarded
- as reactionary by the advocates of stored-program computers." (p. 25)

- For more info, you may want to look up some of H&P's references, or
- look through the IEEE Annals of the History of Computers.
