Computer Lib/Dream Machines

Computer Lib/Dream Machines is available at the Internet Archive [0]

It consists of Computer Lib, concatenated with Dream Machines, which is the "flip this book over and read Dream Machines" aspect.

The term "intertwingled" entered my vocabulary at the time. (and stuck)

Since it just preceded the Altair, was a major inspiration.
