| Note:A total of 255 base address settings are |
| available. The switches are a binary representation |
| of the decimal memory addresses. SB2/7 is the Most |
| Significant Bit and switch SB3/6 is the Least |
| Significant Bit. The switches have the following |
| decimal values:SB2/7=512, SB2/8=256, SB1/8=128, |
| SB1/7=64, and SB1/6=32. Turn off the switches and add |
| the values of the switches and convert to hexadecimal |
| to obtain the correct memory address. (Off=1, On=0) |

| Note:A total of 31 user numbers are available. The |
| switches are a binary representation of the decimal user |
| number. SB3/5 is the Most Significant Bit and switch SB3/1 |
| is the Least Significant Bit. The switches have the |
| following values: SB3/1=1, SB3/2=2, SB3/3=4, SB3/4=8, and |
| SB3/5=16. Turn off the switches and add the values of the |
| switches to obtain the correct user number. (Off=1, On=0) |

| MISCELLANEOUS TECHNICAL NOTES |
|------------------------------------------------------------|
| To install the MATH/16 Coprocessor daughter card, remove |
| the CPU from its socket on the PC-SLAVE/16N, and install |
| it in the socket on the daughter card. Then insert the |
| daughter card into the socket from which you removed the |
| CPU on the PC-SLAVE/16N card, so that the pin 1’s on the |
| daughter card are pointing in the same direction as the |
| pin 1’s of all the chips on the PC-SLAVE/16N. |
