One of the problems with the Q-dos was that it's internal filter had a clear
center stripe. This stripe created a clear separation between left and right
images. It therefore photographed a single object as though it were two
independent objects, much like a dual lens system.  It was this separation
in the Q-dos system that caused card boarding.

Ditto!

Some months ago I started to hammer together a web page explaining single
lens 3D. It's been sitting there un-finished, and a bit shabby (eg. images
don't work yet), but it does have a page describing how to make a single
lens anaglyphic lens at:

Also, there is a graphic which may help explain the cause of card boarding at:
