Computer Collection Web Pages
|
Welcome! These pages contain information on IBM Personal System/2 Model 25 computers as well as some Microchannel expansion bus and other IBM PS/2 hardware related information. I lost much of my collection from a major basement flood in 2004 caused by the negligent behavior of city government. Updates since then have been pretty sporadic if they happened at all. In recent times (relative to when I'm writing this in early 2026), I'm not doing nearly as much with PS/2 systems and Microchannel hardware as I used to. It's been a good, long ride. Much of this computer hardware provided enormous value in terms of learning experiences, far beyond its purchase price. Unfortunately, time gets even with stuff in ways that aren't always easy or possible to fix. People and their interests change. The majority of contemporary operating systems don't run on this hardware any longer and software of the time is increasingly left behind as new features and security measures come along that will never be well supported (if at all) by that older software. When you can find some current software that still consents to working on this hardware, that software and the things one interacts with (like web pages) have often become too "heavy" a burden for these systems, no matter how heavily upgraded they are. That said, I still have a few systems around in working order and sometimes it is fun to revisit the past. I don't have parts of any kind for sale. Nor do I plan to part with the complete systems I still have. These web pages will certainly remain online, though largely unchanged from how they currently exist. Please feel free to drop me a line. I may not always be the quickest to respond, but I love to read e-mail and will reply as soon as I can! Should you not get a reply, please check your spam filter or junk e-mail folder. -- WW, March/April 2026 If you have some IBM PS/2 or Microchannel hardware that's in need of being rescued, please take a moment and drop me a line. I'm still generally interested in doing so. |
