I have the PCB layout pretty much arranged and was just starting on the power traces when discovered some more problems. 1) AT some point I must have shorted something out, because several of the bypass caps now have BOTH pins glowing green for being part of the Vcc net. I have not yet tracked done the cause of this, or the fix. Hopefully more on this later. 2) I found that several IC have no power. I know that John Doty does not like to have his schematics cluttered up with surperfluous Vcc and Gnd connections. But at the other extreme, I just discovered that 7404-1.fp has implicit connections to Vcc and Gnd nets in non-printing attributes, but the identical looking 7404-4.fp does not. Is there some way to indicate which symbols are powerless and which have non-printing power connections built in? This is especially important in quads and hex parts that have many slots. And is there a way to change the symbol used without deleting the instance and re-entering all the data by hand? I don't gattrib allows changing the actuacl symbol file used, just a few of the attributes. Slowly making progress. Mike
