Computer Collection Web 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 as well as some MCA and PS/2 related hardware information. I've also posted some pages about a few of the various PS/2 and Microchannel clone systems I own, both now and in the past. (Unfortunately, my collection was heavily damaged in a 2004 flood caused by the negligent behavior of city administration. Many things could be saved, some could not and others slipped away before I knew one way or the other. Ever since that time, updates to this page have been...sporadic...at best. As such, many things have fallen into disrepair. I make no claim that information here will be updated on any kind of a schedule, or even at all.) New! Schematics for selected IBM PS/2 models are available as of June 2015. Link present in the table below, on the right hand side. 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. 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/Lenovo has taken this stuff down. I have a mirror of this stuff (see the lower right corner of this page), although until recently the links did not work. (No thanks at all to Dynamic DNS Network Services, who rendered their free services useless after the last major update to this page in 2006.) I am always looking for PS/2s, Microchannel hardware and any Microchannel clones that are in need of new homes. If you're located in the US and have such things, send me an e-mail through the link above. Likewise, if you have PS/2 or Microchannel software, manuals or any other resources...drop me a line! |

generally don't believe in being an ass when it comes to using my
