Hi Alan...

A NuArc is a commercial plate burner UV unit normally used in making 
lithography printing plates as well as exposing circuit boards, silkscreens 
and other things.

A snow leopard is an OS for the Mac computer.

Mark Nelson, the creator of PDN hangs out here...he can answer any q's you 
have.
