Groovy computers from 1975

I picked up the book FORTRAN IV For Business and General Applications by Harice L. Seeds, published 1975 by John Wiley & Sons, Inc at a library booksale. It has some spectacularly dated pictures. But folks today tend to forget that computers were once huge, and had less processing power than your washing machine. So here's what real computers looked like.

If anyone wants this book (my FORTRAN days are over) please e-mail me.
