I need a copy of Jim Weir's Aero 'Lectrics article "Make the
Worlds Cheapest Intercom."...

Hi David,

Didn't find that one on either of Jim's download pages:
http://www.rst-engr.com/kitplanes/ (7/99-8/02 articles)
http://www.rst-engr.com/rst/magazine/index.html (8/77-2/98 articles)

There is a 1978 "$10" intercom project at the second link (~$28 in
2003 dollars). You might also check local libraries including
colleges & universities to see if they have Kitplanes.
