    To begin specifying the addresses for the memory,there are two separately addressable blocks of memoryspace available on the board, called blocks a and b. Jumpers are used to specify what the base address is for each of these two blocks, within a 64k total memory space. Alternately, one (or both) bl...

    If the jumpers in area g are switched from the way the board is normally shipped, then the base address of block a will be controlled by jumper area e and the base address of block b will controlled by jumper area f, instead of the other way around. If this is done, then the address which is accesse...

    Other boards. The way you specify the address spaces within block b is as follows: first, you specify the base address of block b using jumper area e (or you specify in area e that the block is disabled). If it is not disabled, then you use jumper area j to specify whether the 4k of prom occupies th...
