The PC Jr. was IBM's attempt to tap into the budding home personal computer market of 1983. While the IBM PC Jr. had many positives with regard to the general home user, it also had several limitations that doomed it in the marketplace. I bought my PC Jr. in 1985 from my older brother who never quite figured out what to do with it. Feeling nostalgic, I decided to Crack Open the IBM PC Jr. to see what was actually in the case.
One of the first things you notice about the PC Jr. when you go to crack it open is that there are no screws on the outside of the case.
I wonder why all the manufacturers decided to go with cases shut tight with screws in the 20 years or so after this PC was on the market.
