The IBM PC's Page

I think most people can honestly say they have used one of the late, so-called great IBM PC's and spin-offs built thru the 80's. What I mean are the now so-called out-dated, obsolete IBM PC, PC XT, PC AT and PS/2 series of computers. They were very popular when they were built because they came from the creator of the first "PC", the IBM Corporation. Starting with the IBM 5150, better known as the IBM Personal Computer (PC for short, thus the term used today, "PC"), they installed 64k of RAM and twin 5.25" Full Height drives into a relatively small sized case for the year it was designed (1981). It does very little by today's standards, but if they built it and people bought it, then it obviously must have done something worthwhile.

My idea with this page is to provide information on the machines mentioned above, answer peoples hardware/software related questions about them and also try to add a few stories of people and their experiences with them. For example for co-op education they stuck me with a PS/2 Model 30 that did not have Windows of any sort and really didn't do much else than run DOS and connect to the AS/400 Mainframe. That was in 1994, so even then this machine was out-dated. So, if you have any other ideas about what I can add to this page, let me know.
