It emulates System/370, ESA/390, and z/Architecture systems. However, you would still need a properly licensed OS to run. Its exactly like VMware workstation, VirtualBox, or HyperV. If you could "acquire" an image of z/OS, it will happily run on z/OS Hercules. IBM would definitely frown upon this, though. -Brandon Sent from my Sprint Samsung Galaxy S10+. ________________________________ From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on behalf of Greg Price <greg.pr...@optusnet.com.au> Sent: Friday, April 10, 2020 12:23:02 PM To: IBM-MAIN@LISTSERV.UA.EDU <IBM-MAIN@LISTSERV.UA.EDU> Subject: Re: Bringing up skills learned on z/OS Hercules in interview?

My understanding is that IBM generally considered IBM employees to be licensed to run IBM software in the course of their work for IBM. So, for example, an IBMer wishing to see if some licensable IBM software could run under Hercules by actually trying it out would not be subject to penalty from IBM - BUT if anyone who was not working for IBM tried it then it may well be a VERY different story. Just my opinion...
