The following links lead to pages I have either created from
scratch, or added information to. These pages cover a variety of
Microchannel-bus option or expansion cards that are used in IBM PS/2
computers (Models 50 and higher) or some of the few clones that are
floating around. You may also wish to view my computer collection.
Before using any information presented here, read and understand the notice and disclaimer section below. If you are selling an item discussed here on eBay or anywhere else, read the "Information for eBay Sellers" below.
At the very least I have provided an adapter outline and a set of
component IDs. Whenever I have more information or files relating to
the item in question, I have placed such files online. Some of this
information does not exist elsewhere.
If you can't find something or have questions, please don't
hesitate to ask.
Some pages are slightly (or more!) broken from a disk failure that took
place long ago. For a variety of reasons, some good and many not, I've
never really repaired all the damage this did.
NEW! 04/07/2019 -
The Xionics XIP-D page has been updated with a great deal of
information about what it is actually used for. Thanks to Jeff White
for supplying this information.
04/29/2018 Minor maintenance updates were made to the CD Burning and M-ACPA
pages. (These primarily address issues with link rot.) At some point, I
may create a "news" page, if only to archive the older entries below.
03/12/2016 The Cabletron E3xxx
series pages have been unearthed after spending quite some time
unlinked and forgotten! At least I got the drivers before the darkness
fell. Updates are pretty sporadic these days, I'm not doing as much
with Microchannel as I once was. And there are still some pages that
don't work because I'm a professional lazy-butt.
01/27/2013 - While some may have considered these pages
to be in a state of slumber (and I'm not saying they are far wrong), I
do still run Microchannel machines to this very day. There's a lot of
stuff I should probably do here, but in the meantime, check out the
updated Rancho Technology RT-1000MC page if you need the option diskette.
At some point I need to repair the Madge TR page and the IBM 486SLC2
upgrade page. I also have some files pertaining to the Thomas-Conrad
TC4046 adapter. As always, I am interested in any information, software
or actual Microchannel hardware you may have.
01/14/2010 - The Thomas-Conrad TC4046 page is finally
up. Not only is a card outline available, but so are the manual and
pocket guide (both in PDF format). I am desperately seeking the drivers
and supporting software for this card! Do you have them? Drop me a line!
I am also aware of the fact that at present, there are some broken
pages and links here. I haven't had the time to find and fix
everything, but I am aware of just about all of the damage.

More projects will be completed as I find the time to do them. Please
note that I only document hardware. I don't presently have the skills
to write device drivers or software for your adapter. If you don't see
a card here, or if you have any information at all regarding something
shown here, drop me an e-mail. You will be credited for your subsmission if you wish.
