Boards in 1 GitHub repository, designed in KiCad, that use the AT27C040-70PU by Microchip Technology (-40℃~+85℃ 4.5V~5.5V 4Mbit EPROM PDIP-32 Non-Volatile Memory (ROM) ROHS). See how each wires it, with its parts, size, README and files; the AT27C040-70PU’s symbol, footprint and pinout are on its own page.
