Hi Glenndk
Sorry I didn't see your post until now.
I went to that link and it was not found.
What do you know about the Wurlitzer omni series?
I have been working on one for quite a while now in my spar time.
I managed to free run the 8085 and now I don't think it's bad.

8085 processor help

Post by Jalex2 on Sun Apr 19, 2015 12:33 am

Hi all
I don't know if anyone could help here but I will ask anyway. I know this is a lot to ask. LOL
I am working on a Wurlitzer omni 6000 and it has an 8085 Processor that runs for a few ms then stops
Most of my experience is only in analogue so I know very little about digital other than the basics. 
I assume the interrupts are stopping  it but I don't know how to troubleshoot it.
It only has 2k Ram so I think it should be a simple circuit. I can post a manual page or two
if that would help. If I just knew what would stop it from running it would be a big help.
It's been sitting for about 25 years and it was my dad's so I have no idea if it was even running when
it was put in storage.
  Thanks Jim
