In trying to make some Polymorphic docs available to a larger (but probably still small) group of people, one thing I have is a LOT of Polymorphic documentation/manuals. This all came from Polymorphic Systems after they shut down here in Santa Barbara. and is arranged by part # in folders in about three or four file cabinet drawers. While I haven't counted them, a WAG is probably around 100 or so manuals, each with a printed out manual and some (most?) have a floppy disk with the manual on them. Years ago, I had some uneducated person say these couldn't be original manuals since none of them have any pictures or graphics (that someone hadn't heard of cut and paste back when these manuals were put together.) I don't recall any graphics in the manuals, but it has been a LONG time since Ive looked at them so I could be wrong about that. If anyone needs a copy of a Polymorphic manual, let me know that part number and I'll see if I have it. I have a 600 dpi scanner and it is fairly easy to make copies. The 5 1/4" disks are probably around 50 years old, and I have no idea if they are still readable. Among all this stuff is about 20 assembly floor manuals I have looked at, but not done anything with. This is more stuff I would like to get scanned to avoid it being lost to posterity. Included in them are mods to the computer boards. Part of the motivation to do this was a post by Sellam (founder of VCF) a while ago talking about people passing away with potentially a lot of irreplaceable or uncommon stuff in their possession (I'm currently 80.) Normally I would bring some of this stuff to VCFMW, but I couldn't get a room at the convention hotel since they were apparently sold out, and thus I won't be attending this year.

Floppy disk

by Murray McCullough

54 years ago the 8 inch floppy came into existence. It can be said it helped to make micr-computing possible. Happy computing. Murray 🙂

OS/2 1.x question

by georgijgalcev1570＠gmail.com

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
