HP7475A

HP7475A undressed – It´s basically 3 motors and (the thingy that moves up and down using induction) 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.
