Edison made flats? I’d never known that. I’ve got an early 20th c Edison cylinder here on the desk, helps me keep some grip on history while using this, uh, late 20th c CPU.

They were about 1/4 inch thick. My wife’s grandfather used to sell Edisons back in the 1910-1925 in Ada Oklahoma. His first shop was a tent.
