 TOPIC -----------------------------------------------------------

 Some of my group's Apple II software applications run in color on the Apple
 IIGS and look terrible.  (Most of the programs with the problem are written in
 BASIC.) Is there a routine or call for putting the Apple IIGS into monochrome
 mode?

 DISCUSSION ------------------------------------------------------

 What monitor are you using?  The AppleColor Composite Monitor (A2M6020) or the
 AppleColor RGB Monitor (A2M6014)?

 AppleColor Composite Monitor
 ----------------------------
 There is a switch behind the front access door that turns the Composite
 Monitor
 to a green character on black background display.  This will help the
 displayed
 image to appear more clearly.

 Additionally, the Apple IIGS Control Panel has the Monitor CDEV for selecting
 color or monochrome monitor.  This may help if you're using the Composite
 Monitor in the single-color mode.  This setting affects only the composite
 output of the Apple IIGS.  This is the only method we know for setting the
 Apple IIGS to monochrome mode.

 AppleColor RGB Monitor
 ----------------------
 There are certain issues that affect the display on the RGB Monitor's graphics
 page.  If the graphic images are not placed on even nibble boundaries, there
 will be color bleed that many consider unacceptable.  On the RGB Monitor, the
 only solution is to rewrite the programs, with the even nibble boundary issue
 in mind.
