I employed my special “pull things off the shelves randomly” research technique the other day and once again it proved effective. I believe that machine is part of the R2 computer. I don’t think I’ve ever seen a picture of it before, but it’s the right era–this must be early 70s–and I can’t think of what else it could be.
I know much, much less about the R2 than the R1 and I would really welcome any help on understanding more about it.
As I kept flipping through the photos, though, I was delighted to discover that the kid with the wavy hair in the R2 picture had convinced a pretty girl to have lunch with him.
Bonus: This was an accident, but I like it.
