I've got a in-good-shape copy of this book, which
I enjoyed
very much-
If you liked that one, try to get a copy of _IBM's Early Computers_
by Bashe, et al. It's unfortunately out of print, but it's worth
having. Also in the same "series": _Building IBM_, and _Memories that
Shaped an Industry_, by Pugh. I think these latter two are still in
print, but they're less essential IMHO than _IBM's Early Computers_.
