   | Note: Configuration for IRQ selection (JP1) is             |
   | unidentified.                                              |

   | Note: If you are installing the TC3045 in an 8-bit slot,   |
   | make sure that the interrupt is set to 2/9, 3, 5, or 7.    |
   | The TC3045 will not operate if the IRQ is set to any of    |
   | the other settings.                                        |

   |     Note: A total of 255 base address settings are         |
   |     available. The switches are a binary representation of |
   |     the decimal memory addresses. SW2/8 is the Most        |
   |     Significant Bit and switch SW2/1 is the Least          |
   |     Significant Bit. The switches have the following       |
   |     decimal values: SW2/8=128, SW2/7=64, SW2/6=32,         |
   |     SW2/5=16, SW2/4=8, SW2/3=4, SW2/2=2, SW2/1=1. Turn on  |
   |     the switches and add the values of the switches to     |
   |     obtain the correct memory address. (Off=0, On=1)       |
