Of course that it is purely based on culture. Many other cultures write books in this way. As when reading a book, I expect to see some vital information about power or voltages on top left. It has been changed in time, and most power supply circuits, regulators and filters are being positioned on bottom left, but I still feel more comfortable to see them otherwise. Also, I expect to see input signals at the left, expecting the resulting output at the right. Of course, digital circuits, with mixed pins, not even talking about bi-directional circuits, messed this up completely, not even talking about several different supply voltages. In the old electronic schematics, it was clear that the left side of the paper would tell you the main line voltage path, the transformer section, then the right side would be the useful electronics, of course, at that time, mostly electronic components identified as 6BQ5, 12AX7, 6V6, and so on... :) Perhaps the top to bottom may have connections with reading, or the natural way to understand hidromechanical machines (water flow). One thing that I feel completely annoying is when a signal path going to right, not being a feedback suddenly returns to left, it really pesters my good mood, even understanding that sometimes it is done by lack of space on the paper or something like that. But it is being fun to see what the "uncultured" mind can comes up with different ways to do the same old things. Wagner. -- http://www.piclist.com#nomail Going offline?
