There is currently zPDT, which implements zArchitecture on a laptop for development work only. In the past, there was Flex-ES, which allowed both development and production work. And there is Hercules/390, which I have read has been used by "some" to run z/OS at various levels (hearsay, of course). Of course, the z hardware has historically been a cash cow for IBM. Apparently not so any more. I, personally - in my ignorance, think that going to an ISA emulator on top of the Power hardware would be the best of all worlds. This would allow a single CEC to run "iSeries" software under "i/OS", AIX, z software such as z/OS, z/VM, z/VSE under the "z/Emulator", and Linux. It might just kill z/Linux because why run Linux on an pSeries under a z/Emulator when it will run native? Basically everything could be run on a single CEC that most would want other than Windows (which I personally _don't_ want, but that's my personal problem). > > Dana > > -- There is nothing more pleasant than traveling and meeting new people!
