No it was not true - I had a Tandy TRS-80 in 1977 which I used to learn to code and to compile statistics for my professional association - which data later went on to be used in international negotiations. We wrote our only software.
I had a REXXON in the early 80’s with 4 20” discs. We wrote our own code in Basic and maintained a complex database. Trained several disabled ladies to do date entry who went on to get good jobs.
