Wow, I actually used the later version of this at my dad's office back in the 1980s. Whatever I would type would be put on the top of punch cards and the punch cards would get punched. I kept typing basic program lines on them. What memories.
I do remember the keyboard feel although the keyboard was much more modern than the one in the listing. I believe the keys were doubleshot, but a shallow spherical with sharp edges to prevent anything falling in between the keys--probably to keep the underlying mechanism from being damaged/dirtied.
