There are three ways that I can think of to get B&W slides.

What you describe is a contact printer.  I have a 4x5 contact printer
(a metal box with a light bulb, an opal glass and a hinged top to
press the film against the glass).  You might be able to find one at a
garage sale or photo swap meet.  It would probably be best to cut the
film into pairs (at least for the Sputnik) and contact print them one
pair at a time.  This way you don't have to worry about film hanging
out of the contact printer, and you can print only the good pairs.

Agfa(?)  makes a B&W slide film called Scala.  The big catch is that
processing is done via mail order at one lab in the US.

If you use T-Max 100, Kodak makes a B&W reversal kit that produces
slides from T-Max 100.  This requires that you do your own processing
at home.
