Screenshot (unsure why it's inverted ? will work on that, but
currently very tired) is of the "options" dialogue box in the Monitors
control panel that you get when you hit "options" with the monitor
that's hooked up to the RasterOps card selected.

To install RasterOps Graphics System Software:

1\. Install 32-bit QuickDraw. How or if you have to do this depends on
the Macintosh and the version of Apple System Software you are using.

If you are using a Macintosh IIci or IIfx, you do not need to install
32-bit QuickDraw. 32-bit QuickDraw is already in the Macintosh IIci
and the IIfx ROMs.

If you are using a Macintosh II, IIx, or IIcx and System 6.0.3 or
6.0.4,
copy all the files from the "32-Bit QuickDraw 1.0" folder on the
RasterOps
Graphics System Software disk into the System Folder of your hard disk
or startup disk.

If you are using a Macintosh II, IIx, or IIcx and System 6.0.5 but you
have
not installed 32-bit QuickDraw, install 32-bit QuickDraw using one of
the
following methods:

A) use the custom installation procedure with the Apple Installer
program
that came with your System 6.0.5 to install 32-bit QuickDraw, or

B) copy the "32-bit QuickDraw" file from the Apple Color folder in the
Printing
Tools disk into the System Folder of your startup disk, or

C) copy all the files from the "32-Bit QuickDraw 1.2" folder on the
RasterOps
Graphics System Software disk into the System Folder of your startup
disk.

2\. If you are installing any RasterOps board which supports pan,
zoom,
and extended desktop copy the file named "RasterOps Monitors
Extension"
on the RasterOps Graphics System Software disk into the System Folder
of your startup disk.

NOTE 1: Do not copy the "RasterOps Monitors Extension" file if you are
installing only one of the following boards. These boards do not
support
pan, zoom, and extended desktop.

ColorBoard 208
ColorBoard 232
ColorBoard 264
ColorBoard 264/SE30
FrameGrabber 324NC
FrameGrabber 324PC
ProVideo 32 (ColorBoard 232 + SFX)

NOTE 2: You must have only one "RasterOps Monitors Extension" file in
your System Folder. If you are installing more than one RasterOps
board,
use the latest version of the "RasterOps Monitors Extension" file.

3\. Reboot your Macintosh.

4\. Follow the procedures in your RasterOps manual to set pan & zoom
options, number of colors, etc.
