This paper presents Z3VR, an interactive simulation of Konrad Zuse’s Z3 computer in a Virtual Reality (VR) environment, intended to give users the full experience of working with this historically significant machine. The paper explores other Z3 simulations and VR programming environments and draws comparison to Z3VR in terms of their accuracy and interface approach, where applicable. It details the creation of the project in various aspects and lessons learned from implementing and testing the VR user interface. It further evaluates how effective the project is as an educational tool in terms of teaching users about some concepts of low-level programming, and proposes future work to be done on Z3VR for higher usability and potential application in museums.
