The pin name defined in the symbol is identical to the net which is to be wired automatically. In this library the device names are the same as the pin names of the symbols, therefore the correct signal names appear next to the supply symbols in the schematic. <author>Created by librarian@cadsoft.de</author> >VALUE >VALUE SUPPLY SYMBOL SUPPLY SYMBOL CONNECTOR series 057 contact pc board low profile headers straight >NAME >VALUE SUB-D >NAME >VALUE 1 10 11 19 >VALUE >NAME >VALUE >NAME SUB-D >NAME >VALUE >Name >Value RESISTOR chip >NAME >VALUE >NAME >VALUE >NAME >VALUE CAPACITOR chip >NAME >VALUE 1/6W Thru-hole Resistor - *UNPROVEN* >NAME >VALUE >NAME >VALUE 1/4W Resistor, 0.4" wide Yageo CFR series <a href="http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf">http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf</a> >Name >Value 1/2W Resistor, 0.5" wide Yageo CFR series <a href="http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf">http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf</a> >Name >Value 1W Resistor, 0.6" wide Yageo CFR series <a href="http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf">http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf</a> >Name >Value 2W Resistor, 0.8" wide Yageo CFR series <a href="http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf">http://www.yageo.com/pdf/yageo/Leaded-R_CFR_2008.pdf</a> >Name >Value >Name >Value >NAME >VALUE Resistor Basic schematic elements and footprints for 0603, 1206, and PTH resistors. $C800 COMMON 2K $CNxx 256 BYTES $C0(8+N)x 16 BYTES small (0.1uF?) ceramic capacitors on all chips same style capacitors on +5, +12, -12 to GND IWM has internal 10K pull-ups for RDDATA and SENSE
