Yes, and there were still connections to telegraphs, which used all upper-case. Sholes was much inspired by Hughes' telegraphs that used a piano-like keyboard with keys in alphabetic order. The first early adopters/beta testers of Sholes' Type-Writer were telegraphists who transcribed Morse code. First after that did Remington get involved.
