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
