In which yr hmbl svt _finally_ gets the right spare parts through the post in order to fix his Tandy CGP-115 pen plotter --- a printer which works by drawing on paper using four tiny little ball-point pens.

(Reupload to fix editing problem)

The 60 fps version of the final plotting video is here: https://www.youtube.com/watch?v=Mezy3hranNg ...and if, for some reason, you want to see the original bodged repair, the entire two-hour marathon is here: https://www.youtube.com/watch?v=UZsfJWGeXmk
