Kodak used to make what they called the "Tri- Chem Pak", which was small packets of Dektol, powdered stop bath and plain powdered fixer. You mixed the developer, processed the film, then diluted the developer 1:1 and made prints with the same chemistry. That was my first experience with darkroom work, done in the bathroom at home dip processing 620 film in a tray and contact printing with a scrap of glass using the bathroom light.
