cardboard foldup HP-45



#4

The first ad for the HP 35 was a page that made into a mock HP35.
I spent 2 days trying keystrokes on the mockup before I decided to but it. One of the peddlars had one, and he said get your own, so I did. My boss borrowed it for a negotiating session with a customer who started throwing numbers at him, he threw them right back and won the day. One fellow bought one for show and walked around with it on his belt. He came to me in tears, his battery would only last 5 minutes. I referred him to the manual. My battery lasted longer and longer as it was really used.

Goodness. I don't quite know what to say about this.

I guess that's one advantage of the cardboard model: very good on batteries!
