I look at design efforts like golf. Low scores are better, but nobody plays a round with 18 holes-in-one in a row. My most humbling: back in the 1980's I wrote an ECO with about 15 lifted pins and 50 or so red wires, a chip glued onto the board "dead bug style", plus a piece of coax (!). (Didn't catch *that* case in simulation....) This on a board with about 180 TTL packages. Here is the amazing thing: The first version of the ECO was the rattiest write-up you ever saw, with white out and sticky-notes and scribbles in various colors of ink. My tech and I gave one board to Lucy to put in our ECO on a fresh board since our prototype was pretty well hacked up by then. Our instructions were for her were to go home after doing the ECO, and we'd check out the board and if it worked leave a stack for her to do in the morning before we came in. So far, so good. Except that after checking out the board, I decided to rewrite the ECO so that Lucy could read it more easily. Unfortunately, I forgot to put either the scribbled *or* the neat version of the instructions back on her workbench before going home. I got in and found a stack of 6 boards with a note: "I couldn't find the instructions so I had to do these from memory -- hope they work." They did. Every one perfect. Lucy was a jewel. I am still astounded to this day at Lucy's memory for rework instructions. -dave _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
