       @foone My all-time favorite fined is in the HP358A (= worlds best voltmeter)If you send the command "XYZZY" it answers "I see no cave here"

       @tomjennings @nina_kali_nina Delay lines recently got crazier:Sandy Toksvig claimed in her Turing lecture that Turing thought gin would work as well as mercury.

       @tomjennings @nina_kali_nina Back then the limiting factor was impurities in the phosphor coating, I wouldn't be surprised if you find 256 bits slightly tricky, and 1024 very, very hard...

       @tomjennings @nina_kali_nina Before oscilloscopes there were oscillographs.BSTJ has you covered:https://archive.org/search?query=oscillograph+bstj

       If your are interested in the history of programming languages, we have a treat for you in Datamuseum.dk:Peter Naur's son, Thorkil, has scanned almost hundred original documents and correspondence from the creation of the ALGOL60 language:https://datamuseum.dk/wiki/Bits:Keyword/PERSONS/PETER_NAURIf you read Danish, Thorkil lays it all out here:https://datamuseum.dk/wiki/Peter_Naur_Algol_60_DocumentsMy personal favorite document is this telegram:https://datamuseum.dk/bits/30009303(For young people who wonder what's going on:That's basically an "email" from 1960.  You know what the best part was ?  No spam!  Because the sender paid actual money.)

       @brouhaha @larsbrinkhoff @ricci I have the same good impression, but it's not clear to me if they are taking a "risk-of-loss" based approach to resourcing.The highest failure-to-recover ratio for us in datamuseum.dk is (non-CDC-origin) hard-disks from the 1990ies, about one in ten hard-disks are not recoverable.
