TOD:
I had very little dealings with mimeograph machines and their ilk, other than getting freshly printed test papers in grammar school and holding them up to my nose and taking a deep whiff.
I was somewhat fascinated with the Xerox machine at my local library during my early high school years. Imagine--I could make copies of pages from my favorite theatre-related books to keep as my own! But at ten cents a copy, this fascination didn't last very long.
For some reason, my HP scanner at home has a setting with which you can make your scan look like early photocopies, with blotchy artifacts, blurry and shrivled print and badly-contrasted photos. I wonder who has a need for that sort of feature?
