The very first personal computers, like the Apple II, were sold as development kits to developers/hobbyists because these were the only people who would even think to buy a personal computer in 1976 and 1977. These development kits contain all of the information one would need to create software and hardware for these machines. Is that so unusual?
Although I was very young, and it was a log time ago, I'm not sure I agree with you. My dad purchased an S-100 bus system from George Morrow's Thinker Toys in 1977. It came with CP/M, there were games, including Star Trek and Adventure, there was even a word processor of some kind (not WordStar, something else). It certainly wasn't used as a "development kit" -- outside of maybe knowing a little BASIC, my dad didn't know how to program and used the computer for writing letters, and for playing games (which drove my mother nuts :))
