Look Ma, I shrunk the HP 7475 plot!
🕑 Added 2021-07-25 06:27:17 +0000 UTCCouldn't resist to share with you the story of one of my viewers, Graham N., and what happened to the plot he made on his trusty HP 7475A:
"Really enjoyed your last video about the 7475A plotter. It reminded me of a time in the early 1980’s when I was working for a project management software company and needed to plot a barchart. I started the plot before going for a lunch break and this was the result upon my return. Just a minor issue with the scaling factor!"
He has actually kept the plot to this day, he says he counts it as a career highlight. This is a recent photo he made just for me. Thanks you Graham N. for the picture and the story!

Pens are a pain. There are pens available on eBay, usually if the package is sealed they might work. Or you revive old ones like in my video here: https://www.youtube.com/watch?v=h-oj4HrTH14 . Finally there are some companies that still make new ones for $$$.

I still have one boxed up in storage, I used to plot pcb's with etch-resistant ink back in the late 80's. I should get it out and see if still works. Are pens still available or is there some other solution for that? Thanks - Ben Edit: Just found a video from some guy called CuriousMarc 😉 about refilling/replacing plotter pens.
