+ * High resolution graphics in Apple are a significant change from its

+ * black, purple, or blue available; alternating rows can be black,
+ * green, or orange. 
+ *
+ * Some of this has to do with the space constraints available to the
+ * Apple II: the hires graphics buffer is held between $2000 and $3FFF,
+ * which is only 8k RAM. Some of this has to do with the peculiarities
+ * of the NTSC format, because the Apple II was designed to work with
