In the January 1982 issue of Micro Sistemas magazine, Tomas Roberto Kovari, Microdigital's engineer, stated that the machines were being sold with a photocopied manual, while a printed version was being developed.[8] Kovari estimated a potential market for 10000 machines in Brazil, with expected buyers being novelty seekers, students and self employed professionals.[8]
According to some sources, the TK80 was never commercially produced, with only prototypes existing.[2][9][10]
