I collect and use a variety of vintage pen plotters. My favorite type are the gantry style which are typically made by Roland. The DXY series of plotters were made to sit on top of a table, either laying flat or at an angle using the provided triangle wedges or built in kick stand.
In November 2021, I posted a short video on Twitter of my Roland DXY 1150 pen plotter drawing a generative wobbly circle design on top of a 5.25″ floppy disk. A few people responded that they would buy one of the floppies. This got me thinking about the medium of a floppy disk that I was using.
