I think I first saw one of these devices in our house when I was a kid in the mid 80s. My dad was (still is) an electronics engineer, and started a company making data logging devices for weather and environmental data, and was using these for data download and display. His own computer was a self-built machine with a Motorola 6809 processor, with all the boards/parts mounted into an old Hoover Keymatic washing machine chassis [1]. It was funny for ~8yo me to learn that this tiny pocket-sized Casio thing and the Hoover monstrosity in the garage were both "computers". Fond memories.
