Dinosaur Technology -- But fantastic Fun
Hello everybody --specifically Old Timer MVS IBM SYSPROGS out there
There's a great piece of Free Software out there which runs the Real old IBM MVS Mainframe operating system with all it's compilers etc (Fortran / Cobol / PL/1 Assembler etc) and the TSO (Time Sharing Option) on your Laptop / Desktop
Runs brilliantly on Linux -- and faster on my laptop than it ever did when I ran this operating system for Real on the old IBM Iron.
(Works on the unmentionable as well -- but then you need the cygwin package -- and you ARE running Linux are'nt you).
Anyway it's fun -- especially when you get 5 or 6 TSO users to logon to your Laptop
-- Watch real live IBM'ers run round with horror thinking you've breached their security when you show them the master console on a laptop window.
Anyway it's called The HERCULES 370/390 emulator.
Great learning tool as well for any students etc out there as this is still the OS that is used as a model for developing other ones even today.
So if you've ever wanted to play around with a Mainframe operating system on your own computer(s) follow this link
You will need to include T3270 or other 3270 terminal emulator package from your Distro -- it's usually on the DVD / CD as a Binary but otherwise available all over the net.
Have Fun -- and another Sunday Lunch missed :D
I looked through half a dozen pages on the Hercules website and I could find no mention of a license. What license is this software released under?
Be prepared. Create a LifeBoat CD.
It's actually Public Domain -- doesn't need a license -- and this is definitely confirmed by IBM -- The release of their software (MVS 3.8J ) was released in the public domain -- incredible today but then nobody could run this stuff on anything other than their hardware -- and at that time they made their money on hardware -- Software was an inconvenience !!!!.
The PC hadn't been invented -- and even if it had been there was no way you could have run this stuff way back then.
The newer stuff (MVS 390 / MVS ESA ) requires a license.
Actually IBM are also quite helpful at people running the old MVS on their laptops -- gives them free publicity and they might find the next generation of computer scientists. Also they are quite "chuffed" that an OS designed nearly 30 years ago is STILL providing a Multi tasking OS which is a model for today's systems.
So Don't worry -- it's quite Legal.
(As a pro photograper I take a dim view of piracy anyway and have said so many times -- so you can rest assured if you are running this stuff it's quite legal).
Go ahead and have fun.
I'm an MVS Sysprog by trade and have downloaded and started the hercules software on my Fedora box.
The instructions say that you should 'now connect a 3270 console to port 3270'. What client software are you using? Did you download it from somewhere? Or is it built in to the RedHat/Fedora Core?
I'd go for a basis 3270 session, as long as it's free....
Hi there T3270 or is it C3270 --- comes free with most distros -- on SUSE just search the RPM's on 3270 -- and install -- it's on the CD / DVD distro.
Set the correct port as well -- works a treat. Don't forget you'll need at least 1 master console for MVS as well as the number of TSO sesssions you want -- I usually have 2 or 3 TSO sessions so that means having 3 or 4 3270 sessions.
This stuff is great fun to play with -- and even on a laptop you can get better TSO response than the old "Big Iron" ever gave.
BTW to print out JES2 stuff it's just routed to a text file which you can print with any normal editor. Most of the time you don't need to print it.
What license is the HERCULES 370/390 emulator released under?
Be prepared. Create a LifeBoat CD.
It's 100% FREEWARE -- no license needed at all. The project started because a few ex IBM Sysprogs wanted to be able to run IBM public domain software on their own computers -- and the older IBM MVS Operating systems were Public Domain -- strange these days with laywers, compensation etc etc but at that time IBM made its money by selling Computers -- Operating Systems and software were just an irritant.
