Orao was an 8-bit computer developed by Miroslav Kocijan for PEL Varaždin in 1984. This repo includes roms, programs and tools for working with this computer.
First thanks a million for the project, I am a retro collector part of a local computer preservation association, I have been looking for an Orao for a while without success ... so I started building an Orao 2007 !
It seems to mostly work ... I see the clock, bus activity, out of reset, some video output but it looks like this :
I tested all chips, tried LS variants, cpu seem fine, rom checks ok ... I don't know what more to test. Do you have any hint ?
