I could type over 80 words a minute on the old Remingtons! For the 'younger' people who don't know what they are, see this: http://www.ebay.com/itm/Vintage-REMINGT ... SwA3dYG50t
And those keys were hard! You had to push them down real hard for them to work!
As an FIY, you couldn't type faster than a bit over 80 words a minute on them because, if you did, the little 'arms' with the letters at the end that 'hit' the ribbon with ink to print the letter on the paper would get all tangled up as there was room for only one at a time.
