Did you do the steps in order?  If you did, there is legible text with instructions on how to proceed through the program.  If you didn't, there are flashing characters and random symbols all over the bottom of the screen.

The program should work fine with or without DOS.


The dbl-hi-res screen views random graphics for page 1 or a picture if one was previously loaded and random graphics for screen #2.


The four lines at the bottom of the screen should tell you which dbl-hi-res screen you are viewing, and while viewing screen #2 you will see text on text page #2.


While viewing screen#2 the program then clears screen #1 to all white, then switches to view screen #1 and text page #1.


I didn't get too extravagant with the graphics as the program was getting long enough.


When booting up, make sure the FLASH command is not invoked at any time.  If you have a startup program, rename it to something else temporarily and let it boot straight to the applesoft prompt. Then follow the directions given earlier.

Part Nine - is now up, where I tie everything together with a nice API -- as an added bonus I show off my (lack of) artistic talent!





I've also started using the domain http://battlestations.zone - all the old links to my previous (and somewhat pretentious) domain http://lastrationalman.blogspot.com will get redirected.
