In the early 1980's there was a small handheld device that looked like a calculator. It was a tool to teach beginner level programming in BASIC. Its ad slogan was "keep it near you". I never had one and I have forgotten the exact brand name. It was in the American market. It seemed to be marketed at people who knew nothing about computers or programming; the ads said that you could go from knowing nothing to being competent in programming in a few weeks.
Did anyone seriously learn to program from using this? Or was it an obscure failure that become a footnote in tech history? This is getting obscure. What was the tool? It was awhile ago.
