(Brings back memories of talking to Rendition about writing some
accelerated X drivers way back when....)

I presume you are talking about the values read after a sync?

Calling sync was always something to be avoided (for performance
reasons) and the meaning of the resulting output known to only a few.
As far as I am aware, that information was never disclosed (and, yes,
I did ask about it myself at one point).  So, what exactly are you
trying to do that you need to call sync, and is there absolutely no
way to avoid it?

If you really, really must call sync and make sense of the returned
value, you might try to ask some old Rendition people.  However, I
don't know what they would be allowed to disclose at this point.  I
would start with Stefan Podell--although Stefan himself was not a
hardware guy and probably wouldn't know this information anyways, he
probably knows who to contact specifically (Walt Donovan?) and might
know how to get a hold of them.

You can easily find some contact information for Stefan with a minimal
web search, but feel free to email me if you need help.

Chances are, however, that you will not be able to get this
information.
