The IBM 1620 computer at Northfield Highschool, where I first learned to program, had a version of a classic warning to not break the machine, written in humorous pseudo-German.
There are multiple documented versions online, and I don’t have a legible photo of the exact version of the one on ours; I’m trying to come reasonably close to reconstructing it between those references and my memory.
This is about how I remember it:
Achtung! Alles Lockenspeepers!
Das Computenmachine is nicht fűr gefingerpoken und mittengrabben. Ist easy schnappen der Springenwerk, blowenfusen, und poppencorken mit Spitzensparken. Ist nicht fűr gewerken by das Dumbkopfen. Da rubberneckin Sightseeren keepen hands in das Pockets; relaxen und watchen das Blinkenlights.
Anybody from then and there want to contribute to my memory? Even if you don’t have a photo, if you remember it differently I’d be interested in knowing. (There are lots of well-documented versions, all a bit different, from around the globe, but I’m asking about that specific version, not others.)
Why German? Well, perhaps because the Germans were a big deal in science around WWII (which, remember, was closer in time to when I was in highschool than that time is to today). Perhaps because German as formally deployed is ponderous enough that this kind of fractured German is inherently funny. Perhaps because of the humorously incompetent German’s in Hogan’s Heroes on TV.
