In a fit of nostalgia, Mark Kaelin cracked open an IBM PC Jr. — find out what he discovered.
As I mentioned in a previous Classics Rock blog post, I was once the proud owner of an IBM PC Jr. And while the Junior was not a market success for IBM by any stretch of the imagination, it did serve me well back in 1985 when I was a college senior trying to finish my last semester of term papers. That is one of the reasons I jumped at the opportunity to create the Cracking Open the IBM PC Jr. Photo Gallery.
The PC Jr. was IBM's attempt to tap in to the budding home personal computer market of 1983. While the PC Jr. had many positives with regard to the general home user, it also had several limitations that ultimately 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.
As you can see in the Cracking Open Photo Gallery, the PC Jr. had several internal design innovations that eventually made their way into common practice. There are also several design innovations that should have become widely adopted but never were. Overall, I have nothing but fond memories of the PC Jr. Of course, at the time, it quickly became obvious that I was going to need a more powerful PC. And I have been chasing better performance ever since.
