Bil often peppers his talks with allusions to the task of designing a system for low cost and mass production. I don't think any of the existing talks delved into those points specifically, but rather tangentially. It would be nice to have a discussion where he could show a tuples of designs, with one being the normal design or the one that would most likely work in almost all the cases, and then the one that had to be used on the +4/C128 or whatever, to ensure high yield and no loss, with lowest cost, or whatever. * If he wants to riff on this, he could show an example of: o The way to properly fix some last minute issue in the C128 after FCC testing was done o The way they did fix it using transistors, since transistor additions would not trigger the need to redo the FCC cert. I bet, if you scan through his talks, he's noted a half dozen of these, but they are always played off as incidental to the conversation at hand. I think it'd be worthwhile to really dig a bit deeper in the world of design for mass manufacturing and for lowest cost, and what lengths designers have to go to in order to succeed there. Jim
