Owner of original Intel 8080 pre-production layout seeks restorer — handcrafted Rubylith mask shows 5,000 transistors and interconnect patterns of the fabled 2 MHz CPU
The owner of 'the original engineering copy of the Intel 8080 rubylith mask' is looking for a skilled restorer.
A man claiming to be related to Dan Lynch, a notable figure in early Internet history, is seeking assistance in restoring what he refers to as the original engineering copy of the Intel 8080 rubylith mask. The artifact features a handcrafted Ruby lith sheet showcasing 5,000 transistors and interconnect patterns of the 2 MHz CPU.
The individual behind the frame is felt to be a relative of Dan Lynch, a pivotal contributor to the early Internet's success. The Rubylith, a red adhesive film used in graphic arts and chip design, was utilized to define light exposure during photolithography processes. Engineers would cut away parts of the film to shape the processor layout, often marked with pens, tape, and overlays during iterations.
The Intel 8080, pioneered by Federico Faggin, was an 8-bit microprocessor instrumental in personal computing's advancement. The CPU was utilized in the Altair 8800 and as the original target architecture for the CP/M operating system, significantly influencing the later x86 architecture.
