Only now i got it: "IOS", not "I OS". Actually this is not a mainframe but a midrange system, just like the p-series - in fact it is the same hardware.

This system was formerly called "AS/400" and the OS "OS/400" and you will find probably a lot more under these terms than under "IOS". Most of it, even the most outdated information, will probably still apply because the system hasn't changed that much for the last 20 years.

The AS/400 is quite radically different from anyother machine (for instance it has a linear address space which spans memory AND disk space - you move a file and it is dumped from memory to disk) and getting around the concepts is probably quite hard first.

On the other hand the AS/400 is famous for needing next to no administration at all. There are many companies owning a AS/400 and having had no Sysadmin for the last 15 years. Try that with a Unix system, it would be long broken.

The network is an alien thing too: it is called 5250 and works similar to (but is still different from) the SNA system and the 3270 data stream the IBM mainframes use.

Now for the good news: because IOS systems work in p-Series hardware there are still VIOS and HMC and they work absolutely the same way as you are accustomed to. Just the LPARs running IOS are different (inside - they are still the same LPARs from outside, say, from the viewpoint of the VIOS or the HMC).

I hope this helps.

NAME

       fsf-funding - Funding Free Software

DESCRIPTION

       Funding Free Software

       If you want to have more free software a few years from now, it makes sense for you to help encourage people to contribute funds for its
       development.  The most effective approach known is to encourage commercial redistributors to donate.

       Users of free software systems can boost the pace of development by encouraging for-a-fee distributors to donate part of their selling
       price to free software developers---the Free Software Foundation, and others.

       The way to convince distributors to do this is to demand it and expect it from them.  So when you compare distributors, judge them partly
       by how much they give to free software development.  Show distributors they must compete to be the one who gives the most.

       To make this approach work, you must insist on numbers that you can compare, such as, ``We will donate ten dollars to the Frobnitz project
       for each disk sold.''  Don't be satisfied with a vague promise, such as ``A portion of the profits are donated,'' since it doesn't give a
       basis for comparison.

       Even a precise fraction ``of the profits from this disk'' is not very meaningful, since creative accounting and unrelated business
       decisions can greatly alter what fraction of the sales price counts as profit.  If the price you pay is $50, ten percent of the profit is
       probably less than a dollar; it might be a few cents, or nothing at all.

       Some redistributors do development work themselves.  This is useful too; but to keep everyone honest, you need to inquire how much they do,
       and what kind.  Some kinds of development make much more long-term difference than others.  For example, maintaining a separate version of
       a program contributes very little; maintaining the standard version of a program for the whole community contributes much.  Easy new ports
       contribute little, since someone else would surely do them; difficult ports such as adding a new CPU to the GNU Compiler Collection
       contribute more; major new features or packages contribute the most.

       By establishing the idea that supporting further development is ``the proper thing to do'' when distributing free software for a fee, we
       can assure a steady flow of resources into making more free software.
