Key punch cards?

[Mik]

Yup. 80 column punch cards.

[George K]

Yes. Here's what I found interesting.

There are 62,500 cards.

They hold 5 MB of data.

[Mik]

That’s about right. I used to carry big drawers of them into LA County and City Hall to process property searches.

[Copper]

I have a stack in a box around here somewhere.

They are from 1977 when we still did all our work on cards. We discovered tubes not much longer after that.

There was a room full of ladies, sitting at card punch machines there in Dallas, who would collect your hand-written coding sheets and return the stacks of punched cards daily.

That was when real men and ladies did data processing.

[Mik]

Debugging was a bit slower.
