I didn’t use cards much (except for one customer) ,, mostly card image tape files.. kids these days have no idea..
Sorry I didn't make myself more clear on this... When you mentioned the IBM 360, that took me back to the days when I did a bit of programming in IBM 360 OS Assembler and JCL. Though in those days I did use a key punch and I quickly learned never to carry a deck across the room to a feeder without at least 1 rubber band...
But THIS is the "Green Card" to which I was referring... (though mine was actually a bit later and a yellow booklet, but it was still referred to as a "Green Card."

Ever use the 96 column cards?
