Electro-Mechanical Cash Register

Computers have not only made typewriters obsolete and dramatically changed how phones work, they have changed how items are checked out from a store. They allow complex state tax laws to be written. And they help keep track of inventory. Jewel used to have a Preferred Customer Card so they could keep track of peoples purchases. That generated a lot of data, but they never could figure out what to do with it, so they discontinued that card.

Not often you see one of these NCR beasts for sale. Ran one of these at the grocery store I worked at when in High School. $100 will get it for you!
Maureen Grisolia And in those days, we could also count back change!! LOL
Larry J. Pearlman NCR stands for National Cash Register. IBM's founder, Thomas Watson was fired from NCR and wanted to one up his former employer. National became International. And a Cash Register became a Business Machine. IBM.

NCR also developed the Automated Teller Machine, better known as the ATM.

NCR and AT&T eventually combined their computer divisions. I don't remember the details because by that time I had transferred from the Bell Labs' computer division to a Forward Looking Work division.
