Ah yes, Std 91-1984, the unstandard. I've never found two people who could matching symbols for the same part using that standard. But they will each defend what they did as the only correct inperpretation. Plus it just doesn't scale well to parts with more than about 24 pins. (seems fine for vacuum tubes though) ;-) Rick Munden norwood sisson wrote: > David Grant wrote: > >> What are the IEEE norms? Or specs?
