This crude rendition of a sailboat is the oldest silicon doodling that we have discovered to date. It was found on a 1970s vintage Texas Instruments chip of unknown function and the boat's rudder is one of the smallest integrated circuitry features present on the chip. Average transistor dimensions on this chip are between 10-15 microns and the entire chip is about the size of a pinhead. As simple as this sailboat is, it reached the maximum complexity available to technology of the period. We are told by HP chip design engineer Dick Vlach that the designer responsible for this sailboat is Gene Hoff, an engineer for Texas Instruments, and that the sailboat represents a Hobiecat.
