Re: gEDA-user: oscillator confusion

[John Luciani <jluciani@xxxxxxxxx>]

I created a schematic with a resistor connected to pin 8 of osc-1.sym. I then
created a PCB file element with pins 1,7,8,14 and ran gsch2pcb. After
loading the
netlist PCB showed a net connected to pin 8. When I looked in the PCB
file I did not
see any re-numbering of pins.

The element I used for the oscillator is below.
