Part 3: OK open the damn thing already!
There was a pink metal rivet protecting the 30 year old IP on there. (a big fat screw driver took care of it).
Lifting the top casing.... huuuhhh thats a LOT of heavy shielding!
All the analog part being completely useless now, I removed most of those boxes:
OK! Now we are getting closer! ... but does it still work? Yes it does, so the VDC/CPU does not need all that top stuff to display a signal and to boot. Great!
My 20$ is on the middle box with the two pink protection rivets.
