HP7475A
HP7475A undressed – It´s basically 3 motors, a solenoid
some buttons and some computori bits
The buttons allow for intimate play with the plotter.
Drawings made using the button interface (Horse, Toilet, Robot (from top to bottom)), disregard the circles as they were not made with the buttons.(paper is precious)
Holding P1 and P2 while turning the machine on makes it plot a demo!
It is multicolor, but this was made with only 1 pen
Stonks are raising from the ashes of devastating financial crisis of 1981-82
parallel to serial to USB 2.0 to USB-c allows the plotter and computer to talk to each other
With HPGL incantations you can make the plotter make different shapes, lines and text.
With inkscape you can trace images, and turn vectors into HPGL.
Plotting around is the best way to understand the relation between screen and paper.
The plotter would randomly stop mid-plot, and the "error" light would start flashing.
The same file would stop at different times.
A byproduct of this are terminal logs like this:

By changing pens for each run you can see that it does not error at the same point. suggesting that it might be a hardware issue rather than software (maybe).
By simplifying the image one could easier keep track of what was going on, kinda.
Somtime around this point it became evident that the issue was that the roller that moves the paper would get internally stuck.
By making the images up of lines orthogonal to the papers movement, the strain on the roller was minimized thus leading to more successful plots.
Still it would throw an Error once in a while. To salvage a plot, one can guesstimate on how much of the HPGL has been run, and delete it from the file, before plotting again. This practice is not perfect hence, the doubled blue lines in a portion of this plot.
By splitting images into layers based on the color channels or thresholds, one can make low fidelity imagery some would say it has an "interesting aesthethic".
With a semi-reliable plotter at hand, the next task was to escape the prison of only being able to use, mostly green, small strange pens.
Some scotch-tape and Lærertyggis/tac-it, makes pretty much anything a pen-plotter-pen (weight is a limiting factor)
By taping the pen to the pen, it creates a doubled image with an offset. Crayons are cool^
Brush pens introduce something "organic" to the very machinic
it might be a bit messy, but only in the good way
Watercolors can be used
A parallel-pen makes the demo even more "artistic"
