Learning Assembly Language on the TRS-80/Tandy Color Computer - Programs #9 & #10
Introduction It's finally time for some graphics animation with programs 9 and 10 from the Inman book: Assembly Language Graphics for the TRS-80 Color Computer - by Don Inman and Kurt Inman with Dymax Program #9 - Draw Cylinder and Piston, Erase Piston Program #9 draws a cylinder on the screen in graphics mode 1R, using colour set 0. It then draws a piston in the cylinder and proceeds to erase it, then draw it - until you press the X key to exit. It serves as a stepping stone to Program #10, which is why I grouped them together in this blog post. I found once I had Program #9 working, I wanted to tackle Program #10 right away! Hopefully you'll feel that way too.
