The following appears to have been diverted off. If it has already

Everyone needs to be real careful about quoting previous messages - 
listserv is hyper sensitive about detecting mail loops and it may
mistakenly think a message has already gone out if it sees something

Message follows:

That sounds real familiar.  I used to design those for Bell & Howell.
(US Pat #US04494840  01/22/1985  Dual lens image rotation system). Those
can be converted to rear projection.  What do you have, a 900 series
with the works in a drawer?  Or a 500 series "rocker" You would want a
second lamp assembly, have to move the transformers outside (or replace
the lamps).  The lens to object distance is typically 22", and you need
about a 12x mag......more for viewmaster....
Anyway, you can do it if you are into it.  Edumund
Scientific has a book called Popular Optics....
