Note:
Presently, Acc-9E, 10E, 11E, and 12E boards make no distinction between A, B,
C, and D base addresses, because they do not use address lines A13 and A12.. If
one of these boards is set up for a certain base address 0, 2, 4, or 6, it will respond
to any of the four possible settings for this address (A, B, C, or D), and no other
board may be placed at any of the settings for this numerical base address.
