It depends on the sockets. To an extent, it also depends on the chips. > A lot of headers are designed to be "stacked" end to end and form a > continuous 100 mil spacing of pins.

But there are sockets that are designed to be stacked end-to-end (that is, pins 1 and N of one socket next to pins N/2 and (N/2)+1 of the next). I've never tried stacking them sideways (1 and N/2 of one next to N and (N/2)+1 of the next), but based on memory of the sockets I have (they're at home and I'm not), I'm fairly sure at least some sockets would do that just fine. As for "depends on the chips" - I've seen some chips whose cases extend far enough that you can't stack them end-to-end with only 100 mil spacing regardless of the sockets. 200 mil is fine; 150 mil would probably work, but I have't tried it. But I've also seen other chips whose cases end right at the edge of the operational portion of the pin; they can be stacked substantially closer than 100 mils end-to-end. And I've never seen a DIP with anything mechanically preventing side-to-side 100-mil stacking (which is not to say no such exist). /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML [EMAIL PROTECTED] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
