If you are familiar with the DP 422 from Dynatech Colorgraphics I could use your help. We have one that is giving an error:

Colorgraphics Brush Processor Downloader
[No Response from Brush Processor]
Loading Input and Output Board Setup

Frames buffer retrace interrupts not active, Not OK
Real-time machine control will not work. Press <space> to continue anyway...

Also have a new pc to hook up to this that is giving us the error:

Warning: Brush Processor Not Found. Video chassis is off, disconnected or malfunctioning.
Press <Esc> to ignore and continue, any other key to abort.
If you hit any other key it goes to the D: prompt.

If you hit <Esc> you get a lot of errors: in the following order:
