Page 12: Adjusting The Video Screen
HAPTER Using the Viewmaster Adjusting the Video Screen Once the Viewmaster 80 is installed in your computer, the monitor may need to be readjusted to provide the optimum 80 and 40 column displays. Although many of the adjustments and controls are different on the various brands of monitors, they all basically do the same things.
Page 13: Software Compatibility
Older versions of AppleWriter ][ and VisiCalc are examples of programs which may require a preboot disk to work properly with the Viewmaster 80 (or any 80 column card). Usually the publisher of the software will provide the preboot program or an updated program which will support the Viewmaster 80.
Page 14: Cp/M Software
Note: Most 40 column software does not automatically deactivate an 80 column card. If you try to run a 40 column program while the Viewmaster 80 is in 80 column mode, nothing will appear on the screen. Use the "Control-Z 1" command to deactivate the 80 column mode or boot your program disk using the computer's power switch.

Hardware Control of Viewmaster 80 40 Column Override There are four holes on the Viewmaster 80 card located between the two video jacks.
