   The Commodore 1520 and the other variants based on Alps plotter mechanisms were a great introduction to pen plotters and I’m still amazed to find them stuffed into the oddest of retro tech like calculators and keyboards. The gears on these suffer over time and split but I designed 3D printed replacements that have been working well for me.
