HP 7090A Measurement Plotter Test Plot

My 7090A broke while I was working on the 83522A so I had to switch over to address it - The Geneva wheel had broken and the rubber pen caps in the carousel were sticking to the pens pretty badly. I posted about this on the EEVBlog - https://www.eevblog.com/forum/repair/hp-7090a-measurement-plotting-system-329125/msg4239913/
