As I am doing this in "Sprint layout" a software that is awesome for reverseing a PCB like this (just draw traces above a scanned picture) but editing is a pain. I will do very very little modifications. this is just to get a gerber. AND to verify the schematic is correct. (they sometimes differ against the reality.. like small parts of the 3640) so when this is done I might on next boored businesstrip do schematics in eagle or so. and from THERE do a completly new routing etc. but maingoal is simply to have replacementpcbs.
I have ideas of at RF area add a footprint for 15KHz VGA and also rework the CXA area to support a more modern version of it not needing those delaylines etc. we'll see there.
but.. replacement PCB and gerber that will be the maingoal (YES! I will release all files. even the sprint workfile)
