   | Note: A total of 127 memory base address settings are      |
   | available. The switches are a binary representation of the |
   | hexadecimal addresses. Jumper A3 is the Least Significant  |
   | Bit and Jumper A9 is the Most Significant Bit. The jumpers |
   | have the following decimal values: Jumper A3=8, A4=16,     |
   | A5=32, A6=64, A7=16, A8=256, A9=512. Add the values of the |
   | jumpers with pins 2 & 3 closed to obtain the correct       |
   | memory address. (On=pins 2 & 3 closed, Off=pins 1 & 2      |
   | closed)                                                    |
