Or look at the original (Apple II+ generation) manual for the card,

which has a full circuit diagram, and shows the internal wiring of the

jumper block.

It is a 16-pin jumper block, wired as follows:

1 --\ /-- 16

| |

2 --/ \-- 15

3 --\ /-- 14

| |

4 --/ \-- 13

5 ------- 12

6 ------- 11

7 ------- 10

8 ------- 9

i.e. 1-2, 3-4, 13-14, 15-16, 5-12, 6-11, 7-10, 8-9.
