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

Re: MC6800 MUDBUG

by Mark Waterbury

I found this document via google searches for information about "U of Arizona MUDBUG 6800" -- https://ntrs.nasa.gov/api/citations/19840010841/downloads/19840010841.pdf Not sure this is the document the OP referred to, but it did come from a "government" web site (NASA related).
