APPLE II

Summary: Apple suggests setting the jumper on the 80 column card to hi-resolution graphics mode. However, we have found that setting the jumper to hi-resolution mode can cause garbage to be displayed in Multiplan. We recommend leaving the jumper in the off position for hi-resolution graphics. The following are the Superserial card switch settings:

Switch #1          Switch #2 4, 5, 7 = ON       1, 3, 4 = ON    1, 2, 3, 6 = OFF    2, 5, 6, 7 = OFF Copyright Microsoft Corporation 1988.
