I was lucky enough to work with Dr. Alan Kay to create six full sized replicas of the Xerox Alto displays. Two are in use at the Computer History Museum in the San Francisco bay area and the other four are destined to a museum in the UK,

I created these using a large FDM prints mounted to a frame made of lasercut and bent aluminum. So! Much! Sanding!

Inside each display where the CRTs were in the originals is a NUC computer running ContrAlto, a bytecode-accurate simulator of the OS and software written at PARC for the Alto. During the opening event at the CHM several of the original PARC engineers used the replicas, mostly to check whether or not their code was still in use.
