James,
Thank you for the swift reply.  First of all, let me just introduce myself.  My name is Kevin Keith and I like in Houston, Texas.  I am 14 years old at the moment (I will turn 15 at the end of the month).  I have always had a huge interest in computers.  I currently collect old computers.  Primarily older Macintosh systems and other exotic UNIX stuff (SGI, Sun, NeXT, etc.)  However, just recently I have become interested in old PC systems.  I have acquired a PS/1 Expert, a PS/2 Model 30, and I am going to pick up the original IBM PC in a few days.  I love these systems.  For one thing parts are a LOT easier to find than the other systems (and cheaper!).  I am also a big fan of OS/2.  I don't have it installed on a real machine yet (I'm working on building a box for it), however I do run it in Microsoft Virtual PC.  It is a very neat and powerful OS (especially at the time!).  However there has always been one computer that has intrigued me: The IBM System/360.  I have always been interested in that one machine.  I have researched it to no end.  I have even played with it in an emulator.  However it just wasn't the same.  So, then began my quest to track down a S/360.  I was soon stopped in my tracks when I learned that there are very few (if any, save the few the Smithsonian has) in working order.  So then I started researching it.  I then found that the System/390 would be the best system for me.  However upon even further research, I think that an early IBM eServer zSeries would be the best mainframe to get.  I have always wanted to learn more about mainframes.  I will admit however that I have very little money ($100) so buying one is not really and option.  I had no idea mainframes were that expensive.  Then a friend told me that he had gotten some RS/6000 workstations from IBM for next to nothing and that gave me hope.  I have wanted to allow people to learn more about and access a mainframe.  Please, if you have any of the first generation zSeries laying around, I am interested. Although I will take what I can get.  Plus any RS/6000s, AS/4000s, Thinkpads (ones that are compatible with NeXTSTEP/OPENSTEP), or any PCs I would also be interested.  I already know about the power requirements and am prepared to cope with that.  

Thanks
Kevin
