Dave I'm wondering what colors that "LOGO" loads. Are these colors
correct or are they also "off"?

Reason I ask is that if they too are off then they can be corrected on
block 26 ( was block 30 in previous colorForths). This might can be
used to determine just how off the colors are.

What I fear for this problem is the same fear for Nick's display
problems. These colors for the editor are hard coded in the kernel,
where the editor is defined.

We still don't know what the kernel looks like, tho we can speculate
from what we know about older colorforths and what we find in the
execution of the system.
But, speculation doesn't fix the problem.

What's needed is at least a listing of the kernel as it was run
through the assembler, or the construction files. I wonder that if we
don't have all of the files used to create and recreate this system
from scratch, maybe do to some protection ( as we appear to no longer
be working with an environment under Public Domain ) then maybe we
shall never have official copies due to that protection.

No, one has said anything either way.

I suppose dissassembly is needed. This, like most computing is still a
tad over my pay grade, but I'll get there if I have to.

Best of luck, Dave
I'll help where I can
