The Hotbit HB-8000 was an MSX1 home computer developed and sold by the Brazilian subsidiary of Japanese corporation Sharp through its EPCOM home computer division, in mid-1980s. 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]

Versions 1-1.2

The Hotbit had three versions: 1.0 and 1.1 with gray and white case and 1.2, with a black case and a ROM slightly modified to solve an ASCII table compatibility issue with the other popular Brazilian MSX, the Gradiente Expert.
