What "virtualization magic" do you mean?
You mean taking a program which hasn't been recompiled since 1970 and running it (the 1970 executable) on hardware released in 2014 under an OS from 2015? Of course, it will work. There's no virtualization there, just reality. What 70's technology in particular are you thinking of? The latest Enterprise COBOL compiler is just over a year old.
- StillBored 9y agoWell I said it originally, and I was referring to the fact that a lot of the zseries hardware is actually just software emulation running somewhere that makes a piece of regular hardware look like a zseries peripheral. Take the disk subsystem for example, the disks are just boring old SCSI disks fronted by a linux/PPC controller which is making them look like ficon CKD/DASD disks. Sure, sometimes IBM has a little "secret sauce" in place to ease that transition, but its not at the level of actually writing native 3390 tracks on modern multi TB disk drives.
