1) General OS/2 questions

1(a) What is Team OS/2 about?

Question 1(a).1 - What exactly is Team OS/2?

Team OS/2 is a highly informal organisation dedicated to telling the world
about the advantages of Operating System/2 (OS/2), an advanced operating
system for personal computers. Faced with a large amount of ignorance and
misinformation about OS/2, Teamers respond by demonstrating the operating
system to others, and educating them about its strengths and weaknesses.
Teamers are all volunteers with a genuine enthusiasm for OS/2 that
translates into a wish to spread that enthusiasm to others.

Question 1(a).2 - How did Team OS/2 originate?

Shortly before the release of version 2 of OS/2, an IBM employee called Dave
Whittle had an idea. He, like many others at that time, could see that OS/2
was an excellent program, but like many others, he was frustrated by the
lack of attention that it was receiving in the computer press and elsewhere.
As a result, he decided to form a group of OS/2 enthusiasts who would help
each other to promote OS/2 at the grass roots level. This organisation grew
beyond his wildest dreams to encompass Teamers both inside and outside of
IBM. Currently, Team OS/2 has more than six thousand members worldwide. Less
than 5% of these are IBM employees.

Question 1(a).3 - What does Team OS/2 do?

Anything that promotes OS/2 to other people. Examples include, but are not
limited to:

   * Showing OS/2 to friends and workmates.
   * Demonstrating OS/2 to local stores, sometimes "adopting" a store.
   * Participating in electronic conferences discussing OS/2.
   * Helping exhibitors at computer shows to set up OS/2 demonstrations, and
     answering OS/2 questions.
   * Promoting OS/2 at user groups, possibly starting Special Interest
     Groups dealing with OS/2, or starting OS/2 user groups.
   * Running OS/2 BBS systems, carrying OS/2 files.

Not to mention anything else that springs to mind, often on the spur of the
moment. Above all, Teamers do what they do because it is fun.

Question 1(a).4 - I'd like to do one of the things mentioned above, but I'm
a bit nervous about going it alone. Is there anyone I can ask for help?

Yes. Many Teamers are willing to offer advice through electronic
conferences, and you may be able to find Teamers local to you this way. For
demos, you might like to get in touch with your local IBM office, if you
have one. If you are setting up an OS/2 User Group, then IBM can also offer
some help; contact ibmpcug@vnet.ibm.com via the Internet. In particular, the
Fidonet Team OS/2 echo has many contributors that also run user groups.

Question 1(a).5 - What is Team OS/2's position on Windows, Windows 95, NT,
and other competing software?

Well, Team OS/2 is an informal organisation, and as such has no views on
anything. In my experience, and yours may differ, the majority of Teamers
feel that OS/2 is good enough that we can promote it on it's own merits,
rather than resort to rubbishing competing products, which can often give a
bad impression, alienating people who might otherwise enjoy using OS/2.

Question 1(a).6 - Are Team OS/2 membership and using or supporting a
different OS mutually exclusive activities?

Absolutely not. Being a fan of OS/2 does not mean that a Teamer has to avoid
all other OSes. There are now a wide range of other PC and non-PC operating
systems such as Linux, Windows NT, Windows 95, NextStep, and System 7, and
all of them have different strengths and weaknesses, so it's possible to
like more than one.

1(b) IBM and Team OS/2

Question 1(b).1 - What is IBM's relationship with Team OS/2?

IBM has no control or authority over the activities of Team OS/2. It no
longer provides formal support for Team OS/2 activities.

IBM's support for Team OS/2 was traditionally strongest within the USA, but
they have liasons in sixteen other countries, although it is unclear whether
any of these are still operating. Their email addresses are listed in
section 1(b).3.

Question 1(b).2 - Do I have to work for IBM to be a Team OS/2 member?

The answer to this question is a categorical NO. Although Team OS/2 contains
many IBMers who are active participants, the vast majority are users,
programmers, students, and other enthusiasts from outside of IBM.

Question 1(b).3 - How do I contact IBM's Team OS/2 support?

IBM has now withdrawn support for Team OS/2, so they can no longer be
contacted. Some of the international contacts below may still be able to
help though.

International contacts:

Question 1(c).1 - How do I join Team OS/2? Joining Team OS/2 is very simple. There is no formal membership application process. All that is necessary is to do something that promotes OS/2 to others, no matter how large or small, and you are entitled to call yourself a Team OS/2 member. Once you have done this, you may wish to place the text "Team OS/2" in any electronic messages you send, and you may wish to have your name placed on the register of Teamers kept by IBM, but neither of these steps are essential to becoming a Team OS/2 member, just a willingness to promote OS/2 to others. Question 1(c).2 - How do I get my name placed on the register of Teamers? The Team OS/2 membership database has been undergoing a bit of a facelift recently. If you would like to join, then the easiest way is to use the World Web Web - point your browser at http://www.teamos2.org/jointeam. Regretably it is no longer possible to register other than over the Web. ---------------------------------------------------------------------------- 2) How to contact Team OS/2 members 2(a) Electronic conferences Teamers frequent many electronic conferences, some of which are listed below. If there is a conference that you know of that is not listed below, please let me know. 2(a).1 - Fidonet The Fidonet echo TEAMOS2 is on the echo backbone in Zones 1 and 2, and is also taken by sites in zones 3 and 6. It serves as a meeting place for Teamers worldwide to discuss issues relating to Team activities, as well as serving as a point of contact for many OS/2 user groups. There are also several national Fidonet echoes in existence, for example Germany and France both have national language Team OS/2 echoes. 2(a).2 - Internet / Usenet The newsgroups comp.org.team-os2 (moderated) and alt.org.team-os2 are specifically devoted to Team OS/2, although many Teamers also follow the newsgroups in the comp.os.os2 hierarchy. Of particular interest to Teamers is the comp.os.os2.advocacy newsgroup, also frequented by several staunch NT supporters. some of the posts in this newsgroup are rather extreme in nature - you have been warned! There are also a couple of OS/2 related mailing lists. To subscribe to one of these lists, send mail to the address specified with a blank subject line and the text sub in the message text, filling in your details as appropriate. Do not include an explanation or signature, as the request will be processed automatically. List name: os2users Location: McGill University in Canada Topic: general OS/2 discussion Address: listserv@vm1.mcgill.ca List name: os2-l Location: the Netherlands Topic: general OS/2 discussion Address: listserv@nic.surfnet.nl List name: team-os2 Location: the Netherlands Topic: Grass roots promotion of OS/2 Addresses: listserv@nic.surfnet.nl List name: teamhelp Location: the Netherlands Topic: Team OS/2 help desk Addresses: listserv@nic.surfnet.nl In addition, there are several Team OS/2 related mailing lists running off the Team OS/2 World Wide Web server. Details of these can be found at http://www.teamos2.org/joinlist. 2(a).3 - Prodigy Seek out the OS/2 club, which has both files for downloading and message areas. 2(a).4 - CompuServe / CIX 'Go OS2USER'. Section 9 is dedicated to Team OS/2. 2(a).5 - GEnie The OS/2 roundtable (page 1400) is the place to look here. Look out for the announcements of upcoming Realtime Conferences (RTCs) in the Upcoming Bulletin Board conferences section. 2(a).6 - Delphi The Teamers here are to be found hanging out on Custom Forum 41. 2(a).7 - America Online Head for the Computing icon, OS/2 topic. AOL has regularly-scheduled OS/2 chats on Tuesdays at 11:30 p.m., Thursdays at 9 p.m., and Saturdays at 9:30 p.m. EST (Grenwich Mean Time minus 5 hours.) 2(a).8 - WWIVnet Dave Allen Walker hosts a Team OS/2 subboard on WWIVnet, which can be subscribed to from WWIVnet or WWIVlink as follows: Subtype: TEAMOS2 Host: WWIVnet: @5555 WWIVlink: @19984 2(b) Face to face Often it's nice to meet fellow Teamers in the flesh too. There are two main places where there is a good chance of meeting Teamers face to face. 2(b).1 - User groups OS/2 user groups usually have a large contingent of Teamer members, and there may be one near you. These are mostly found within the USA, although the International OS/2 User Group is based in Cirencester, UK and many other countries (such as Germany) now have their own user groups. A list of OS/2 User Groups is regretably beyond the scope of this document. 2(b).2 - Computer shows / store demos If you are planning to attend a computer show, it is possible that you will find a group of Teamers helping out there. If you would like to help out with Team activities at the show, then contact IBM's Team OS/2 support, who will probably be able to put you in touch with those organising Team OS/2's presence. Also, Teamers will often help out at store demos of OS/2. ---------------------------------------------------------------------------- 3) Team OS/2 sources of information This section is concerned mainly with the electronic distribution of Team OS/2 and general OS/2 related information, although the final sub-section covers OS/2 promotional items and software by mail order. 3(a) Where are the principal sources of OS/2 information / software? This section is classified by electronic network. 3(a).1 - Fidonet An extensive selection of OS/2 related material is distributed on file echos called the "Fernwood Collection" and is maintained on the Bear Garden BBS in Vancouver, British Columbia, Canada. FWOS2INFO is the place to look for Team OS/2 info, much of which can also be FReqed (see glossary) from Janet Gobeille's BBS (1:382/902). Also worth a mention is the OS/2 Shareware BBS (sysop Pete Norloff, node 1:109/347), located in Fairfax, Virginia, USA, phone number 703-385-4325, carrying one of the widest selections of OS/2 related files and echos in the the world. The BBS is also connected to the Internet at bbs.os2bbs.com (subscribers only) and the WWW at http://www.os2bbs.com. In England, Monusci, the BBS of the International OS/2 User Group is a good source of OS/2 information and files, and access is not restricted to User Group members. The Sysop is Mike Gove, node number 2:255/100, phone number (01454) 633197. The International OS/2 User Group has moved since this information was obtained, so this may be out of date. 3(a).2 - Internet Several OS/2 related anonymous ftp sites are available on the Internet. The two main sites are ftp-os2.nmsu.edu Directory: /os2 ftp.cdrom.com Directory: /pub/os2 IBM's own official OS/2 FTP site is located at software.watson.ibm.com Directory: /pub/os2 The IBM OS/2 device driver repository is at ftp.europe.ibm.com Directory: /psmemea/os2drivers These sites are mirrored in several places around the world, including src.doc.ic.ac.uk (England) Directory: /computing/systems/os2 ftp.funet.fi/pub/os2 (Finland) Directory: /pub/os2 ftp.informatik.tu-muenchen.de Directory: /pub/comp/os/os2 (Germany) A more comprehensive list of FTP sites can be found in the OS/2 FAQ. For information about ftp, consult the glossary in Section 5 There have been an enormous number of OS/2 related World Wide Web sites set up recently, so much so that it is impossible to list them all here. However, a couple of sites worth looking at, from which you should be able to find the rest, are: www.ibm.com IBM's own WWW site www.austin.ibm.com/pspinfo/os2.html IBM's OS/2 page www.europe.ibm.com IBM Europe www.teamos2.org Team OS/2's home on the Web www.mit.edu:8001/activities/os2/os2world.html The MIT OS/2 home page 3(a).3 - Others Any details of OS/2 sources on other networks would be greatly appreciated. 3(b) What general documents are available? Here is a list of files that may be useful to OS/2 users and Teamers in particular. It is, however, beginning to show its age, and perhaps a better source of information would be the OS/2 Must Have Utilities List at http://www.musthave.com. 3(b).1 - The Team OS/2 FAQ - TMFAQ241.ZIP Well, you are reading it at the moment. Anything I could say about it seems slightly superfluous in the light of that fact. 3(b).2 - The OS/2 FAQ - WARPFAQ3.ZIP This is a list of questions and answers related to OS/2 generally, maintained by Timothy Sipples. It is posted at regular intervals in the comp.os.os2.advocacy newsgroup, and can be found on many ftp sites, as well as some BBSes. There are a small number of FAQs concerned with more specific aspects of OS/2, such as programming. For a list of these, please consult the OS/2 FAQ. 3(b).3 - The Team OS/2 membership list - TEAMOS.ZIP This document, widely distributed on BBSes, is a list of all the Team OS/2 members worldwide who have submitted their names to IBM, along with their location (city and country), and any electronic addresses, enabling Teamers local to each other to get in touch. The filename is TEAMxx.ZIP (xx being a version number). This list is incredibly out of date, and an update is extremely unlikely. 3(b).4 - OS/2 installation help file A list of problems and fixes for use when installing OS/2 2.1, in INF format. Filename is probably INSIN2.ZIP. 3(b).5 - Trap error guide v1.01 - TRAPINF.ZIP INF file containing a brief description of OS/2 Trap messages and what they really mean. 3(b).6 - OS/2 2.1 performance improvements An INF file describing Workplace Shell performance improvements in OS/2 2.1. Filename: WP21PERF.ZIP. Only of historical interest now. 3(b).7 - OS/2 performance tuning. INF file containing tips to allow you to fine tune your system settings for better OS/2 performance. Filename: OS2PERF.ZIP 3(b).8 - Stupid OS/2 Tricks - TRICKS6.ZIP A list of useful (and not so useful) things you can do to your OS/2 system in INF format. 3(b).9 - APAR lists - 30APR1.ZIP APARs are known problems with OS/2 that IBM is in the process of fixing. The lists contain details of the bugs that IBM know about. Again probably only of historical interest. 3(b).10 - CONFIG.SYS documents There are currently two ASCII documents explaining what the sometimes rather cryptic statements in the OS/2 CONFIG.SYS file mean. These are CFGS_11.ZIP and OS2CFG11.ZIP. 3(b).11 - OS/2 shipping applications - OS2_APPS.TXT Just that. A list of currently shipping applications for OS/2. Often useful when countering rumours that there are no OS/2 applications available. 3(b).12 - OS/2 BBS list - OS2WORLD.ZIP Contains a list of BBSes that carry OS/2 files and echos throughout the world. 3(b).13 - Hardware compatibility table Contains a list of hardware that has been tested by IBM and found to be compatible with OS/2. This can be very useful when buying new hardware, or for finding out if OS/2 will run on a friend's machine. This file is pretty much obsolete now, since OS/2 now runs on almost any PC hardware. Filename: PCMTAB.ZIP. 3(b).14 - The Good, Bad and Ugly hardware list Similar to the hardware table above, but is compiled from feedback from users who tried to get their hardware running under OS/2. It is in INF format, and is organised by peripheral type (e.g. 'soundcards') - filename GBU109.ZIP 3(b).15 - Workplace Shell keys reference - WPSKEYS.TXT A concise reference containing keyboard shortcuts for various operations. 3(b).16 - OS/2 Awards - OS2AWARD.ZIP An IBM produced listing of awards that OS/2 has won 3(c) What newsletters are available 3(c).1 - Team OS/2 newsletter - TNEW09.ZIP This electronic newsletter from IBM in INF format aims to keep Teamers worldwide informed and up to date on Team activities worldwide. This is now defunct, but back issues should be widely available. Available from many BBSes as TNEWxx.ZIP (xx is the version number). Any Teamer wanting to take on the task of creating a newsletter should get in touch with IBM Team OS/2 support (see section 1(b).3 above). 3(c).2 - San Diego OS/2 User Group newsletter - SDIN9410.ZIP An extremely well presented and professional INF format newsletter produced for the San Diego OS/2 User Group, but distributed worldwide via Fidonet and the Internet. Edited by Dave Sichak, each edition contains OS/2 related articles and reviews, as well as a worldwide list of OS/2 User groups. This is worth checking out. The newsletter has now gone print only, but electronic back issues are still available. 3(c).3 - IBM Developer Support News - DSN95AA.ZIP An INF format magazine produced by IBM and aimed at programmers working with OS/2. This magazine tends to contain articles of a more technical nature. The latest filename can be calculated according to the following archaic formula, reproduced from the newsletter itself: Issue Date Zipped ASCII .INF .PS Pages 10 15 Aug dsn4ja.zip = dsn4j.asc 106 dsn4ji.zip = dsn4j.inf dsn4jp.zip = dsn4j.ps 11 14 Sep dsn4ka.zip = dsn4k.asc 54 Explanation of names of zipped files for 1993 Issue 7 and later: DSNymA = Developer Support News 199y issue m ASCII (plain-text) DSNymI = Developer Support News 199y issue m .INF (use OS/2 VIEW) DSNymP = Developer Support News 199y issue m .PS (PostScript) where y = last digit of year (3, 4, ...) m = issue represented as alpha (1=A, ..., 7=G, 8=H, ...) For example, DSN3GI is 1993 issue 7 (=G), the 15 October issue, in .INF format (after being unzipped). 3(c).4 - Others Here is a short list of some of the other newsletters available: CON1296.ZIP - OS/2 Connect EDMI4_1.ZIP - Electronic Developer's Magazine/2 PROS1296.ZIP - PROS/2 - Tampa Bay OS/2 Users Group Newsletter 3(d) Where can OS/2 promotional items / software be found? 3(d).1 - Indelible Blue Inc. (USA) Indelible Blue is an OS/2 only mail order vendor with a large stock of applications. They also have franchises worldwide. Any details on these would be much appreciated.

OS/2 ran on a 286 or better processor, and required a minimum of 2MB of RAM. OS/2 version 1 was enhanced and improved jointly by IBM and MS, and for version 1.1 a GUI (see Glossary below) was added. Version 1.2 introduced the High Performance File System (HPFS), and also a plethora of bugs. At about this time, MS and IBM started to disagree over the future of OS/2, and Microsoft pulled out of the project, leaving IBM to develop a more stable OS/2 1.3 on its own. OS/2 1.x never sold in great volume, and enjoyed only a moderate success in the corporate market for a variety of reasons. It did not run on most non-IBM manufactured hardware, was not really backwardly compatible (having very limited DOS program support), and suffered from a lack of applications. In 1991, IBM released OS/2 version 2.0, a new version of OS/2 for 386 and higher processors requiring a minimum of 4MB (6MB for practical purposes) of RAM, and featuring a redesigned object oriented GUI called the Workplace Shell. It also introduced multiple DOS sessions that would run the majority of old DOS applications, as well as built in support for Windows programs through a licensed version of the Windows 3.0 code. Version 2.1 added improvements in performance and usability, as well as Windows 3.1 support and built in multimedia. IBM then followed this up with OS/2 for Windows, which would take users' existing copies of Windows, and modify them to allow them to run under OS/2. The next release of OS/2, called OS/2 Warp version 3, built on this with substantial an improved install process, reduced memory requirements, and support for many more hardware devices. This was followed by OS/2 Warp Connect, which added full TCP/IP support and Peer to Peer networking to the Warp bundle. The launch of OS/2 Warp version 4 marked a shift in policy for IBM away from the home and small office user towards a corporate environment. The major enhancements were speech to text dictation software and built in Java support as well as a complete suit of networking programs. Beneath the surface, however, Warp 4 has little to offer that cannot be accomplished using Warp 3. 4(b) - The OS/2 family There are a number of versions of OS/2 about. Hopefully this will explain the differences. Where products have not yet been released, details are obviously sketchy and subject to change. * OS/2 1.x - The original release of OS/2 * OS/2 2.0 - The first release of OS/2 specifically for 386 or better computers. * OS/2 2.1 - An enhanced version of 2.0 with multimedia and Windows 3.1 support. * OS/2 for Windows - A version of OS/2 that is functionally the same as OS/2 2.1, but comes without any Windows code, and can use genuine Windows 3.x code that the user has already purchased from Microsoft instead of making her pay for a new Windows license. Surprisingly enough, OS/2 for Windows does not require Windows to run. Windows is only needed to run Windows programs under OS/2. Users of OS/2 2.x
