Yup, this is a punched card modem.


… new low cost way to send punched card data… by telephone

This IBM 1001 Data Transmission System lets you send business information in punched card form, from any office, plant or department to your central data processing installation at the cost of a telephone call.

It speeds collection of information concerning inventory, purchases, payroll, production, etc., keeps you continually informed of what’s happening in your business while it’s happening.

And it does it at low cost.

A simple, desk-top 1001 Data Transmission unit and telephone at each remote location plus a telephone and card punch at your data processing center put you in business. The operator at the remote unit dials the data processing center, inserts a punched card into the transmission unit, adds additional information with the simple keyboard, and presses a button.

The rest is automatic. The equipment reads the card, transmits the information over your regular telephone lines, and reproduces an identical punched card, ready for processing. You can connect a number of departments, plants, offices or customers with this 1001 Data Transmission System.

This is another example of IBM tele-processing* Systems which help business act faster by speeding up collection of the facts on which action is based, tele-processing Systems are available for coordination of anything from a warehouse to an entire company.

    I got a kick out of the 1949-design model 026 keypunch on the other end.

    To be fair, it was almost the Checker Cab of IT – it wasn’t replaced by IBM until the model 029 in the sixties.

    (no, I wasn’t a nerd. I was an Air Cadet nerd.)

    my mom and her sisters used to roll these punch cards into cones, spray paint them red and make poinsettia wreaths out of them. i miss the kitschy crafts of the late 60s.

    I remember reading somewhere that a company called Mohawk in the mid-60’s had a device similar to the IBM 1001 that sent data from computer tapes instead, rather than punch cards, over a phone line. It was basically either a 7 or 9-track tape drive with a modem interfaced to it.
