orao's Issues

Strange video output

Hi !

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 :
video-capture

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 ?

Thanks for helping !
