I think we need to move this discussion to
http://www.tandycoco.com/forum/viewforum.php?f=23&sid=3014c6a337f84d675ee33e05067f3c5e
where a thread with the same name as this one has been started. The forum makes 
posting of images and programs easy.

There are some problems taking digital pictures of a CRT screen as moire 
patterns are generated. Nevertheless I did post an image and will probably post 
more.
The program that loads .bmp files of the type previously described is also 
available for download. Use a right joystick to scroll over images.
