Message from the president Unfortunately, the 4th anniversary party at “The Grounds” had to be cancelled due to the spike in Covid-19 infections in Montgomery County.

Because they were proud of their work and were willing to show it and they wanted people in the future to know where it came from. The mark was generally hidden, and quite often could only be found by someone else skilled in the trade. If you look at the silicon die inside an Intel 8080 microprocessor chip, you will see the stylized initials “HF”. Hal Feeney was one of the designers of the 8080, and the person who designed the physical layout of the chip. Rumor has it that the Soviets cloned the 8080 by doing a straight copy of the chip’s artwork, including Hal’s maker mark. The maker’s mark is usually not in plain sight. On a chest … Read More
