IMPLEMENTING HRAM OPTIONS
HRAM options are implemented by inserting and removing
mini jumper plugs at various locations on the PC board
and by changing the
switches. Figure 3-1 shows the locations of the jumper
areas and the address switches on a 64K revision E
board. Other boards differ as follows:
1.
Jumper areas JP4 and JP6 do not exist on revision B
boards.
2.
Switch S2 is not installed on 48K revision B
boards.
Instructions for determining the revision level of the
HRAM board are given in Section 3.6.
