The plotter is placed in room 204, in the shelf behind the projection screen. Take it out, place it on a desk and connect the serial adapter to your computer. Please do not forget to return it to the shelf when you are done! | The plotter is placed in room 204, in the shelf behind the projection screen.

You have to bring your own pens and paper. So far it seems that some trial and error is involved when working with the HP7475A. | You have to bring your own pens and paper. So far it seems that some trial and error is involved when working with the HP7475A. | ||

To use your own pens with the plotter, you can simply extend your pen’s diameter, by wrapping some paper around it. This way it will fit the pen mount of the plotter. | To use your own pens with the plotter, you can simply extend your pen’s diameter, by wrapping some paper around it.

Use the “HP7475A_feed_hpgl_file_01” or “HP7475A_feed_hpgl_file_02” sketches, which are almost the same (only the buffer handling works differently). Both do not work perfect yet for each case, but almost. For very detailed graphics (for example the “noise.hpgl” file), version 02 works better. Instructions how to use the programs are in the comments | Use the “HP7475A_feed_hpgl_file_01” or “HP7475A_feed_hpgl_file_02” sketches, which are almost the same (only the buffer handling works differently).
