Wow! If you were using a computer that still required punch cards in the 1980s, you were using a very old computer.
I took college courses to learn how to punch computer cards back in 1972, but never had the opportunity to use the skill. The technology was changing as I was in class and computers were coming out that used internal programming and memory systems rather than punch cards.
My first chance at using anything close to a computer was a huge typewriter that used an 8 inch floppy card to store all files. It was text only, and the only display screen was on the keyboard, showing about three lines. It could use maybe a dozen fonts, and you could use variable effects to make a very nice looking typed page.
That was somewhere in the mid 1970s. Even then, it was old. The company that had been using it had discarded it in the trash and I retrieved it in a dumpster dive. It all still worked fine, but the saved files used up most of the disc space. I discovered the reason they tossed it. There was only one disc, and I could not find anyone who sold new discs to add to a collection. The system would no longer delete old files and there was almost no room for new files.
I discovered I could go in, edit out everything in an older file and then resave it with no content and that was the only way to get more space on the disc. That gave me enough room to save dozens of new files, but even then, I eventually ran out of room and could no longer add anything new.
I had the brainstorm of using a large magnet on the disc itself to force erase the content. It seemed like a good idea at the time. Yup, it erased everything. That was when I discovered the operation system was also on that disc and there was no longer any operational function on that beast. Back in the trash, but it was fun while it lasted.
