[Coco] Drivewire on an original Raspberry Pi

[Ron Klein]

Hi Walter,

I did have the DW4 GUI working on older versions of Raspbian (and using a
RPi 1).  When I updated the OS to the latest version of "Raspberry OS", I
ran into the same issues you did.  I, too, went through numerous steps to
get it working, but ultimately decided against it as I wanted to keep as
many supporting libraries, etc., as "stock" as possible for the CoCo-Pi
distribution.  Since DW4 allows for remote connections (using the GUI) I
felt that was good enough.

I have been driven to solve for things based on your reasons as well.  Glad
to see I inspired you to find a solution for this - even though it was due
to a misunderstanding.  :)

-Ron
