Ah, interesting. I’ve never really heard of either!

very carefully. It helps that they're such low density, the drive can probably read right through dust and fingerprints, cause the bits are HUGE. Another fun thing is that they're not random-access. The data is in a spiral, so the whole disk is read from start to finish

I would just pinch them as close to their edge as possible. Had very few failures. Could also write data to them, but on different disc from program. Load then swap.

As an aside, I mostly learned BASIC back then by modifying the games in David Ahl’s book to work on P6040’s limited display and language subset. Think Lunar Lander outputting to scrolling paper tape! Burned 1 page of book trying to hold book open with a desk lamp. Hey, I was 12.

Chris EspinosaVerified account @cdespinosaOK, a little on my history with punched cards. In 1978 I entered UC Berkeley as a freshman, and had to take Computer Science 1: Introduction to Programming in FORTRAN. Required for all CS majors. https://twitter.com/pomeranian99/status/931657563103547393 …Show this thread1 reply 0 retweets 0 likes -

Fascinating story. I personally only intersected w punched cards at glancing angle. My dad took a college course in PL/1 and used them. Helped him submit decks. My high school still had some old class-scheduling computers using them. No real personal use, though.

My dad used them at work and my house was *swimming* in them. We used them for everything, including cutting them into strips and making chains that we hung on the Christmas tree :)

I was recently at the Computer History Museum and I typed one punch card using an alphanumeric punch, and then the same one using an old twelve-key punch where you have to hold a few keys together at a time… and they matched, which I verified by just overlaying them. :·)
