This was attached to the last NOS Rear Fader Control Knob I have here that I'm keeping for my car.....what is this thing?? See below...
That is a computer punch card used for computerized inventory managment. It went in a huge main frame the size of a city block and probably only had about 64K RAM, and a tele-type output as opposed to a screen. I remember those as I used to program for RCA way back when and we used those exact type of inventory tags. Jim.
It is an IBM key punch card used, in this case for inventory. You set a a machine like a type writer, but larger. Enter the data and it punches out the card and it is attached to the part. These cards were used for all sorts of data. Ted
GM's key punch card from the 70's Trying to send an order or return on key punch was about as much fun as a hammer dropped on the big toe :eek2: DW
