There’s AUTOMATION in the Monro-Matic

The MONRO*MATIC Duplex Calculator proves “Years Ahead” for business figuring!

Tough as your figuring problem may be, it can be done speedily, easily, with hardly a thought on the Monro*Matic Duplex. That’s why business has welcomed this great new calculator. “Just what we needed” . . . “Nothing like it” . . . “Great for payroll” . . . “Invaluable” … are typical comments.

Only the Monro*Matic, on the office machine level, gives you *Automation—the modern industrial miracle that does in seconds tasks that take human hands hours. For instance, in work like payroll or statistics where a number of results are needed, the Monro*Matic Duplex works the problems and gives several answers simul- taneously. Whereas other calculators require extra steps.

For the Monro*Matic Duplex adds as it multiplies … adds as it divides. And it stores intermediate results for later use. No need to refigure problems all over again.

Your local Man from Monroe—an expert at business figuring methods as well as at business machines—will be glad to show you on your own figure work just how much you can get out of time-saving, cost-saving * Automation. Ask him for the whole story of Monro*Matic calculating. It won’t cost you a cent for a demonstration! Monroe Calculating Machine Company, Inc., General Offices, Orange, N. J.

    Yeah, that always looked that way to me, too.

    I programmed one of their electronic machines in the mid-70s. It was better than a Wang, but nowhere near as easy to use as the TI and HP hand-held machines that came a bit later.

    I was too hypnotized by the screw-top CN Tower on the left to notice.

    I used a calculator very much like this back in the early 70’s when I worked for the phone company – if you divided by a number which was too small, it would whizz for a long time and then start to smoke.

    Oh yes. My high school had a couple of those calculators and they would run continuously if you did an out of range calculation. We would frantically push keys to get it to stop.
