[Coco] The Graphical Segmentation System.

[Stephen H. Fischer]

Hi,

Your take is quite different from what I got many years ago.

I typed in much of the source but not all. Thus I was convinced.

I looked mainly at what I thought the CoCo could do and felt that it could
at least be a beginning and would be fun.

But please realize, I have the printed book which might give you a different
impression.

It was not the source you looked at that gave me my impression, if that was
all I had then I might agree. I ignored much that was not needed.

As for what it could be used for,

Gaming, I agree. Once the basic simple code was working then what fun things
on a Coco could be done was the time to ask questions.

It's approach is quite different and for sure large numbers would not work.

The different approach is what makes it so attractive to CoCo usage, you can 
do more with less effort.

But it was ~ 25 years ago
