Orao (computer)
From Wikipedia, the free encyclopedia
Orao (en. Eagle) was an 8-bit computer developed by PEL Varaždin in 1984. It was used as a standard primary school computer in Croatia from 1985 to 1991.
Orao (code named YU102) was designed by Miroslav Kocijan to supersede Galeb (code named YU101). The goal was to make a better computer, yet with less components, easier to produce and less expensive. Originnaly Motorola 6809 microprocessor was planned but was abandoned for MOS 6502 due to its significantly more expensive.
