The cashier above is using a cash register made by Data Terminal Systems of Maynard, Massachusetts. The best I can tell, it’s either a Series 300 or Series 400 cash register. I am looking for any information I can get my hands on for these two series of registers by DTS. If you have any receipts, documentation, photos, anything, it would be most welcome.

There is very little information on the Internet about Data Terminal Systems, even though they were one of the first electronic cash register companies in the world and their technology was everywhere, especially in the 1970s and 1980s.

I’d like to get as much information about Data Terminal Systems online as possible, before it’s all lost to forgotten history.

From the Walmart Museum.

The next department store chain to be featured here on the Vintage Point of Sale site will be Wal*Mart. Wal*Mart is a fascinating study in vintage electronic point of sale equipment, as they were leaders in going digital with their entire store operation.

In the photo you’ll see a couple of Data Terminal Systems cash registers, presumably Series 400 registers, to be exact. I’m looking for any information on Wal*Mart’s first run with electronic cash registers: documentation, receipts, anything.

If you have anything to share with the site I’ll be sure to give you credit!
