Has anyone actually gone through the effort to etch new PC boards for early RCA roundies? In this day of digital imaging it would be as easy as removing all of the components from the boards of a junker chassis and then simply scanning the trace sides of each board with a flatbed scanner, using photoshop to convert the images to grayscale, inverting the images, and then printing them on transparency film with a laser printer. A clothes iron could be used to transfer the pattern onto blank PC boards, which could be etched and drilled.
