Hello everyone. I am documenting early OS/2 releases (before 1992). I am interested in all possible information about the released versions, photos of media, screenshots. There is very little on the internet. For example, there is very little information about OEM versions of MS OS/2 1.x, as well as little information about OS/2 1.X localizations. if you are the owner of the package/disks of versions 1.x, please let me know. Best.regards. –Georg

Fwd: OS/2 documentation and software

by Mark Waterbury

Georgi, I saw your post on CCTALK about OS/2 history and early versions. There are many resources available on archive.org. See: https://archive.org/search?tab=texts&query=ibm+os2&page=2 and https://archive.org/search?tab=software&query=ibm+os2 (You can do similar searches replacing "ibm" with "microsoft" in the above.) I hope this helps? All the best, Mark S. Waterbury

Re: OS/2 1.x question

by David Schmidt

The Virtual OS museum has MS and IBM OS/2 versions listed pretty comprehensively (which you can of course run locally): https://virtualosmuseum.org/installation-list/ It includes some Citrix versions that OEM the main providers, too. I have a couple of IBM OS/2 boxes (1.1 and maybe 1.2, I think) that I can snap pictures of media from if you're interested; but there are probably places like the Internet Archive that already have such things: https://archive.org/details/ibm-os2-1.00-extended-edition-3.5-1.44mb - David On Mon, 08 Jun 2026 03:05:56 <georgijgalcev1570(a)gmail.com> wrote: > Hello everyone. > > I am documenting early OS/2 releases (before 1992). > I am interested in all possible information about the released versions, photos of media, screenshots. > There is very little on the internet.

Re: Need Otrona Attache 8:16 MS-DOS Disk

by Robert Feldman

Georgy, One of the software disks that came with my 8:16, which I purchased in March of 1984, has a printed label saying (with the "d" after 2.1.1 hand written in blue ink): <quote> ATTACHE MSDOS REVISION: 2.1.1d SN 1850 48 TPI Date: 02/29/84 </quote> Volume 5, Number 1 (Spring 1985) of "Where It's Att. Official Newsletter of the First Attache/2001 User Group" lists the "Newest" FAUG Library disk as "Attache MS-Dos 2.11e(x) System Disk FAUG211e(x). The latest 'unreleased' Otrona 8:16 master disk for MS-Dos. About to come out when bankruptcy hit Otrona." That same issue says that RAMDISK.SYS works only with 2.11e(x) and not with earlier versions. Issue 5, Number 2 says that "211e(x)" "Includes extensive new hard disk software." Regards, Bob P.S. to Fred: My apologies for not knowing offhand if the MS-DOS version is "two eleven e (x)" or "two one one e (x)". When I get my 8:16 running, I can check.

Need Otrona Attache 8:16 MS-DOS Disk

by Robert Feldman

Does anyone have a working copy of a bootable Otrona Attache MS-DOS 2.11d or 2.11e disk that they can copy and snail-mail to me? All of my disks are giving a "Bad or missing Command Interpreter" error. I no longer have another computer that reads/writes 5 1/4" IBM 360KB disks, so I need a physical copy. Please email me at feldman.r(a)comcast.net so we can arrange shipping (I am in Chicago) and payment. Thanks, Bob Feldman

Project Release Announcement - Vintage UNIX (and others) Online Manuals

by r.stricklin

I've been working on this project for ages. It is not complete. It may never be complete. It is, however, finally in a state that I consider to be eminently usable. A "beta" or "soft opening" - there are absolutely some visibly unfinished areas. But, it can absolutely be used while I continue improving the typesetter and the indexer, polishing the presentation, and adding manuals for new systems. http://www.typewritten.org/Manual/ Some folks were given access to previous development versions and asked not to share the URLs. If you were one of them, please transition to this URL instead; this one can be considered fully public. ok bear. ps. this announcement was also sent to the VCFED forum and the TUHS mailing list
