Unfortunately, as <URL:http://world.std.com/~wware/ncadlisp.html>
points out, Will Ware has shifted the base platform of his NanoCAD
from Scheme & Common Lisp to Java:
"Note: I have not been good about keeping the Scheme version
of NanoCAD up-to-date as MrEd has evolved. You will find some
problems with running NanoCAD 0.2 on the current version of MrEd
(version 53), which I haven't fully sorted out yet. In the
meanwhile, try the Java version of NanoCAD, and I will try to
get the Scheme version updated as time permits. Sorry for the
inconvenience. -Will Ware"
Since the current version of MrEd is 101(?), you may have even more
difficulty (though maybe not).

p.s. But that page also has a neat screenshot of NanoCAD...
