Can you elaborate on the procedure? I've heard this a lonnnng time ago at a PPC meeting, but have frankly forgotten how it worked.

Also, (somewhere) I have some of the little card holders (like those in the photo but blank/generic) from an HHC back in the 80's; I will look for them. They are so much more refined than the 41C booklets, but less easy to use.
