After I have bought this Amiga 500 computer, the cover was in very bad shape. The previous owner tried to retr0bright it, but it didn't work out as planned and there were a lot of spots.
This vintage Canon parallel scanner needed some restoration and for that purpose it needed to be taken apart. It is a bit tricky as some of the parts are glued with adhesive tape and need to be detached very carefully. This small tutorial shows a step by step disassembly instructions of the scanner.
