I'm Gravis, proprietor of the [https://www.youtube.com/CathodeRayDude Cathode Ray Dude] youtube channel, through which I publish essays about old technology. This wiki is a tool I've decided to start using to organize my research data. I claw through an enormous amount of Stuff on my way to reaching conclusions, and it's gotten hard to keep track of what I've found and how it relates to everything else. I hope to use this to make more sense of it all, and I figure I might as well make the results public. == Topics == === Gadgets === ==== Cash registers / point of sale ==== [[Early cash registers]] [[Early electronic cash registers]] n1wnpb3te4pi6dpx5wusqzw2q5ecesb
