Computer Collection Pages

There is "new technology", and there is "high technology".
An IBM MCA machine is still a "high technology" computer.

Welcome! These pages contain information on IBM Personal System/2 Model 25 computers, some MCA and PS/2 related hardware information, and finally a nearly complete listing of the PS/2 systems that I own and operate...

There have been some complaints that these pages don't render properly on some web browsers. A solution to this issue is being implemented, but it may take some time until all the pages have been updated.

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!

I've recently finished some major revisions to this page and others listed in the links below. There are also some new machines below. I'm steadily getting back on track with my collection of Microchannel computers and IBM PS/2s in general. Stay tuned for updates and new information!

If you're looking for disks relating to IBM PS/2s, option cards or anything related that was once on the IBM PCCBBS, you should know that IBM has taken this stuff down. Many links on the WWW are no longer any good and won't give you the files you need. I'd recommend checking the mirrors below in the rightmost column for more information.

Does anyone out there have a 9585 xKx or xNx model system that needs a home? I am looking for one!
