To celebrate the 30th anniversary of the wonderful SR-50 slide-rule calculator the Datamath Calculator Museum gives you one as a present! 

Compared to the old-fashioned original calculator this Windows™ compatible Datamath Commemorative replaces the 4-bit single-chip calculator circuit with Pentium™ power, lacks the acid NiCd rechargable batteries and features even an Online-Manual.
