Editing Computer service manual findings

This page details the findings from computer service manuals (AKA technical manuals or hardware manuals), as these often list all the components used in the computer. A small number of these manuals indicate the keyboard vendor, or the part number of the switch used. In most cases, this information was never disclosed.
