Right, now on to details about the actual video.
All the photos of retro calculators are from this great website: My Calc DB
http://mycalcdb.free.fr/main.php?l=0&p=1
I do not have permission to use the images for anything other than my own personal use. So no, I cannot sell you a copy of "Calculators of 1974". I'm sorry. Because it's amazing.

CORRECTIONS
- At 7:38 I say “400 days” when I mean “400 years”. First spotted by Jim Fortune.
- User "SmackleFunky" spotted a typo in the above correction. Does that count as a video correction? I'm not sure.
- I said 13 days when talking about England's calendar reform of 1752 when they actually skipped 11 days. Sorry! Wednesday 2 September was followed by Thursday 14 September. Spotted by macronencer.
- Yes, I had “refor” above instead of “reform”. Another meta-correction!
- Let me know if you spot anything else. Preferably in the video and not the corrections.
