HOW TO USE THE MAINFRAME.
Download the free program wc3270 for windows. Install it. Set up a connection to cyberdatastorm.com:3270. Your logon ID & PASSWORD will be USER100 & PIZZA OR USER101 & TACOS . You will have access too JCL, COBOL, ASSEMBLY, C++, REXX, and will be able to use the SYSDUMPs. You will be on sysplex1 with full access to 3380, 3390, and 3350 DASD. You will also have access to IBM 3420 TAPE Unit. You can explore what a mainframe operating system is like and how it is different from personal computers. Obviously you will not have access to TOP SECRET or RACF. I often say that anyone can learn PC stuff (personal computers) like Linux, Windows, or Apple OSX by reading just 1 thick 2000 page book. But for the mainframe you need to read about 200-300 of those thick 2000 page books. It is way more complicated. There are 5 mainframe operating systems: IBM Unix called AIX, IBM vm/cms, IBM os/400, Digital Equipment Corp VMS, and the Zos family. This mainframe you are logging into is in the Zos family. It does support full ISPF/TSO and CDC's (cataloged datasets). You will not have access to easytrieve, expediter, endeavour, and CICS.

Super awesome for you to provide this Cyber. If more got educated, things would be more progressed and problems solved easier. Hi5!

Thank You. Mainframes are still used today to run the worlds financial systems. The entire U.S. ACH system runs on mainframes. Also transaction processing houses run on mainframes as well as the entire Federal Reserve Banking System. :) While there are as I mentioned other operating systems like IBM Unix (AIX) ( and many other flavors such as HPUX hewlett packards mainframe unix, ULTRIX (dec), SGI (silicon graphics unix), Solaris (sun unix) and others) Nothing is as prolific or important as the Zos family, which went from os/360 to mvs/370 to os/390 to Zos in it's iterations. Operating systems like os/400 were more suited to insurance companies and 401k managment than financial transaction processing. But they are all interesting to learn about.

Long ago, I had heard that financial systems were running on old systems. ... I friend of mine, working for a major airline about ten years ago, told me that the airline ticketing system they were using was written in cobol. But that they were in the process of porting it over to something newer. I guess that when you spend time and money setting something up, it is difficult, and costly to upgrade.
Just like the power distribution system. The one we're using has been in use for about 150 years. There are better ways of doing it, but the cost to switch would be large, and the will to upgrade is poor.

well, not at all. The Fed runs on mainframes built in 2018. The Zos operating system has gone through many updates every 10 years. The mainframes are brand new with 64 bit cpu's. 14 cpu's per board, 10 boards per rack. Fiber Optic Data Bus. They are faster and much more modern than personal computers.
