Very little is known about this very rare Brazilian computer.
CDSE stands for Centre de Desenvolvimento de Sistemas Eletricos. The Apply 300 is a home computer aimed at computing initiation. As usual with most Brazilian computers, it must be a copy of a more famous computer... but which one ?
The Apply 300 is powered by a Z80A CPU cadenced at 3.24 MHz. There seems to be 32 KB and a 48 KB models. There is a BASIC language bundled in the 8 KB ROM.
Text resolution is 32 x 24, and graphical resolution is only 64 x 44 !
