- Orao (computer)
-
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 and Vojvodina 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. Originally the Motorola 6809 microprocessor was planned for the CPU but was abandoned for MOS 6502 due to its significantly lower cost.
