Just remembered the dream from a few nights ago where I got an antique scientific calculator with exquisite cassette futurism styling, like a high-end camera from 1981, and the only problem was it ran on six D batteries.
@vruba Once I got into retro electronics, I had to start buying (rechargeble) C and D batteries again. So now I also collect retro batteries!
@vruba you could boil a pot of water on those
