I miss my 7475a... I got one (from Goodwill,) in high school for $50. I then hacked together one of the "automatic advance" mechanical pencils to fit in place of a pen, and "plotted" a handwriting font onto standard lined notebook paper. My teacher thought I had the best handwriting in the world! (After all, in the days when tractor-fed dot-matrix were what almost everyone had, seeing pencil on notebook paper, with what appeared to be handwriting - it HAD to be hand-written, right?)

As a drafting/engineering student, I got to use bigger ones at school regularly, and just had to have one for myself. Sold it off years ago. Kind of wish I still had it. The small desk-size of it was nice. (Okay, relatively speaking... It is definitely smaller than a tall drum one, that's for sure!)
