Released in 1980, the Dismac D8000 was the first personal computer manufactured in Brazil.[1][2][3][4] It was also the first Brazilian TRS-80 Model I clone.[2][3]

It used a 2 MHz Zilog Z80A microprocessor, with 16KB of RAM and 16Kb of ROM (containing Level II BASIC).[2] Video output was through a PAL-M television, displaying 64x16 or 32x16 characters text mode or 128x48 semigraphics.[2] The keyboard contained 51 keys and was part of the case, like the cassette recorder and the main processor unit.[5][2]

The machine is considered rare, even in the Brazilian vintage computer market.[6]
