If you're like me, until now you had no idea that one of the world's leading cellular equipment makers originally was a wood pulp mill, and another made playing cards. Clues with asterisks (*) are the featured companies. Enjoy!

About RF Cafe

Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
