Xerox 6085-2 to VGA display adapter...

I have looked at the various pinouts of the Xerox 6085 and it seems as though I can create a simple adapter cable which will convert the output from the display port on the Xerox to a standard VGA signal.
The Video+ signal should go to the RGB inputs on the VGA input and the V/H sync should go to the V/H sync on the VGA input. Some voltage adjustments need to be made since, from looking at the oscilloscope, it seems as though the Xerox's signal os +3V Low and +5V High. It needs to be 0V Low and +5V high for VGA.
So, it appears as though companies such as Extron (who made a converter for the Xerox to output to standard VGA) created a framebuffer because they were doing a scan doubler so as to avoid flicker. I may get to that, but simply seeing some output would be good for now.
Anyway... I hope some of this interests you.

The VGA adapter was a total fail. I thought of using an FPGA for a while.
Just as some more progress. I have decided to wimp out to some degree and use a Raspberry Pi to do this. It occurred to me the other night that in order to do this I would need to have an FPGA which has access to memory and, in order to do this, it would need RAM and a RAM bus. So the more I delved into it, the more I realized that I would need a full computer. So the GPIO and Raspberry Pi seem to be the best solution to this issue.
I hope you don't mind me keeping you updated on this.

I'd be interested in any updates on this. I have a couple of Extron interfaces (RGB 118 plus) and I'm about to get started on trying to get my 6085s working with more modern displays. Any progress on your end?

I know this thread is a few years old but has anyone been able to create a monitor/video adapter for the 6085 to a more modern display (VGA)?
thx.

You will see all the menu in your pc and if you set the port farwarding,
you can control it from anywhere.
