"The second round of Alto 3, with a plan to manufacture entirely from commercial components, was canned in favor of the Xerox Star – a scope-crept project which included an OS and hardware, later only the OS with matching hardware."<p>The Star was essentially the Dandelion which was PARC's own affordable successor to the Alto - a similar soft machine but implemented with then-commodity AMD2900 bit-slice. As far as I know, the Altos were all manufactured entirely from commercial components (7400 TTL mostly). To really commercialize would require a formal PCB design rather than wirewrap and perhaps a more designed enclosure.
