 I'm glad we can agree on this. Of course the Earth is  
  round.

 To try and turn this thread around: I'm looking to make  
 an extended
  memory controller for my pdp8/L. I've got a
wire wrap  
 backplane and
  enough cards to make it work but I've never
done  
 wire-wrap on this sort
  of scale.
 I've got an old Radio Shack Wire wrap tool and a lot of  
 wire. Is there
  any sites that discuss how to do reasonable
wire-wrapping? 
  I think back then they used different wire wrap sized
 wire on the back planes
 
 Oh, yes, the older DEC backplanes MIGHT have used a
different wire size.  But, all I am familiar with seem to
have used #30 AWG wire.  But, I have not worked extensively
with PDP-8's, but I'm pretty sure by the 8L they would have
used the #30 wire.
