PCB Artwork (Added 2 June 2007)

This artwork has been scanned from photographic copies, and is therefore two stages removed from the artwork used by the PCB manufacturer. It is not perfect, but it is the best that can be managed. At the time of writing (June 2007) no constructor has used these scans, so it is not known how accurate they are. Please see the HeyPhone discussion forum for comments and feedback. Please also note that it will be the task of the first constructor who uses this artwork to work out which scan is which, since nobody at CREG has supplied this information for this web page. Please post your findings to the discussion forum so that we can update the following table with the name of the PCB and the orientation of the scan (i.e. top/bottom view and right-way-up/up-side-down). You can view thumbnails of the artwork by clicking here.
