MSX home computer sold in Brazil From Wikipedia, the free encyclopedia
The Hotbit HB-8000 is an MSX home computer developed and sold by the Brazilian subsidiary of Sharp Corporation through its Epcom home computer division in mid-1980s.[1][2][3] The MSX machines were very popular in Brazil at the time, and they virtually killed all the other competing 8 bit microcomputers in the Brazilian market.[1][4]
