Based on what I read in the z114 technical guide, I thought that unless the machine was running in an ensemble mode, the HMC just acted as a remote management console for the SEs. Does the HMC have extra features that the SEs don't? I also have an IBM TS3200 tape library (one of the small 4U rack mount units) that I got broken and repaired. I'll have to see what kind of controller I would need for it. I have seen some FICON switches that advertise having a tape license, I wonder if this means that the controller unit is built in to the switch. >>6.

(Not sure.) I'd really like to get my hands on z/TPF. All of the other major IBM OSes have either ADCD releases, or 24-bit predecessors that are open source, so you can get some experience playing around with them. z/TPF has nothing, and I have never even seen someone do a video, or write an article about it online. It seems like the ulitmate challenge for the mainframe hobbyist. >>It's likely to be less expensive to use one of the IBM offerings. > >Perhaps, but it depends on what the objectives are.

I am sorry, but I have never head this term before, and I could not find a definition online. Is there any way you could elaborate? ________________________________________ From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on behalf of Timothy Sipples <sipp...@sg.ibm.com> Sent: Monday, April 18, 2022 2:02 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: HS student with question about small mainframe DASD Shmuel Metz wrote: >There are several issues that you will need to deal with in order to >get a running system. >[....] >2.

Are you thinking of initial startup/OS installation? On this vintage machine there should be non-tape IPL (startup/“bootstrap”) options, notably HMC DVD. Such options were standard well before the z114. Assuming Enzo gets a working HMC with the z114, and assuming the HMC was ordered/shipped with the z114 (rather than an older carry forward HMC), it should also support USB flash memory drives. And there are some network-based options with the HMC. Without the HMC startup is “much more interesting” at least. >6. A cluster controller and 3270 terminals, with licensed internal code Fun perhaps but not at all required. A cluster control/3270 terminals were vintage way before the z114 debuted. And if the z114 has OSA-Express 1000BASE-T adapters (likely) then it should be capable of OSA-ICC if that’s even needed. >9. An operating system.

Standard commercial licensing IBM z/VSE 6.2 (and VSEn 6.3 I believe) licensing and delivery are still available for the IBM z114 without any unusual or exceptional steps.(*) Standard commercial z/TPF 1.1 licensing and delivery might also be possible depending on how the z/TPF team packages/ships their PUT levels. (Not sure.) >and I don't know whether the free DOS/VSE, OS/VS or VM will run on it. Not without a lot of contrivance. A MUSIC/SP hobbyist license is possibly available if you know the right party to ask, but I really can’t speak to that and don’t actually know. MUSIC/SP would probably work on an IBM z114 since that model machine can start in ESA/390 mode, something that MUSIC/SP requires. MUSIC/SP might be more likely to do more useful things (such as network I/O) on an IBM z114 when it runs under z/VM 6.4. >It's likely to be less expensive to use one of the IBM offerings. Perhaps, but it depends on what the objectives are. If for example Enzo would like to get into the commercial z/VSE or VSEn service bureau business then a used z114 machine might be a reasonable entry point. (*) OK, granted, it’s unusual for a student to apply for an IBM credit check, one of the usual procedural steps to obtain a z/VSE license since IBM understandably wants reasonable assurance its bills will be paid. I assume it’s even more unusual for a student to pass that credit check. But I’m responding to your technical point. :-) — — — — — Timothy Sipples Senior Architect Digital Assets, Industry Solutions, and Cyber Security IBM zSystems and LinuxONE sipp...@sg.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
