I picked this up locally from a gentleman who is a university lecturer - The auto-feeder didn't work but some heads down time in the service manual and a misleading article on the HP Support site helped me get it running again.
Enjoy the auto-feeding plottery goodness of this one...

Very nice! Right out of high school, I took a summer grunt job before college. The owner of the company brought his new dual-floppy IBM 5150 and HP 7475 plotter in to see if I could make it do something useful. Thus began my career! Eventually, he got me a 7550A. A lot of what those plotters did was driven by software I wrote. I like to think that my work with those machines and other things that followed were a not-insignificant contribution to the company's rapid growth and eventual domination of the industry (from a small father/son operation). I never did make it to college! 7550A (and also 7475) are very near and dear to me. I wish I had room for one now.

Great story - It is amazing how one piece of technology can make all the difference to the path of a person's career.

My graduation work has graphs produced by one of these plotters. The sound brings back memories 😀

I find in mildly relaxing to hear the plotter working in the background :)

Definitely - Seems much faster than my 7090A - Need to get some heavier-weight paper to try out if that addresses the slight misalignment in auto-feeding - It has multiple inputs as well, hmmm, maybe a Serial to Network adapter to use it from my PCs...

got the same beast a few months ago, sadly only have the A4 paper tray, but it's feeding fine. missing the catch tray too so it flings the finished plot across the room :)

I'm going to have to make a custom catch tray myself to get it to fit in the place I have it aimed for - I only have one tray but mine had screws in the guides so I could convert it from US Letter to A4. Seems a lot fast than the 7090A I had already.
