Orao 2007


After Zoran Bošković made a replica of the Galaksija computer, inspired by the knowledge that there are more people who like to do something like that, Zoran Tomiša and I decided we do the same with the Orao computer.

Thus was born the idea of a project we called Orao 2007, and after a few months of work we successfully completed it.

Project realization

Since we didn't have electronic schematic of Orao computer, the first step was her reconstruction.

ORAO - RECONSTRUCTED ELECTRONIC SCHEMATIC

Optimization did not bring anything, since Miroslav Kocijan (creator of the original Orao computer) did a great job. The only significant change is in the address decoder, which was realized using GAL16V8. Two EPROMs and RAMs were also replaced with one larger capacity each.
