You might not know this about me, but I spent the first couple of years of my professional career as an MVS systems programmer; first with MVS/XA and later with MVS/ESA. I switched to Unix in the early 1990's, but I still believe that my MVS and mainframe experience played an important role in creating the Unix guru whose words you are reading now (and so modest too :-)
I love complex operating systems and I am also very fond of solving perplexing and puzzling problems. Hence I always kept a soft spot for the IBM mainframe and the MVS operating system. However since mainframes are well outside my budgettary and electrical power constraints I have not worked with MVS for a long time.
However, last week a student pointed me to the Hercules emulator, a complete System 370, 390 and z/Architecture emulator (running under Linux and Windows) capable of running every classic and modern version of MVS, DOS/VSE, VM and Linux/390. My heart exploded with joy and I must admit that I did not sleep for many nights...
I downloaded the emulator and got it running in no time. The Hercules community is a knowing bunch of folks with many years of MVS experience (so nice to be the among the younger members of a group once again :-).
So now I have MVS/370 3.8j running on my laptop, and thinking about playing with VM, and I want to install Linux/390 (to port some software), and of course try to get my hands on a recent release of z/OS, and .... and .... and ....
What about these pictures:
Is this cool or what? |
