Very interesting content. My 40+ years in IT were mostly on Unix - I actually never had to deal with IBM mainframes. After a couple of videos on this channel, I just started with Hercules and TK4-. It's hilariously funny for me to sort of start over more or less from scratch in IT. And to some extend, it has some of the excitement when I started with computers and Unix decades ago.

[@jacekruzyczka3058]

The last time I worked on a mainframe (as an ordinary user) was in early 1999 when querying the library catalog (Bibos; which was a joint venture of all scientific libraries in Austria by then) at university. In the lobby we had real InfoWindow II 3270-standard terminals, and in the branch at our colloge, age-old PCs with 80286 CPUs with some 3270 emulation performed the job. It took up to 5 minutes (!!) to perform a query. The mainframe itself was not an IBM machine, but a Comparex "plug-compatible" one (some 6 meters long with a weight of 2 tons) running VM/390 and quite a bunch of guest systems. A couple of months later it was replaced by another Comparex, which was no larger than a washing machine (the computer itself) + drying machine (disk array?). Bibos was replaced by an Oracle-based catalog named Aleph (hosted on some Unix cluster) you could query by using a web browser.

[@moshixmainframechannel]

Yes. Many mainframes disappeared this way. Taken over by Unix

[@nubaus]

Actually Last time you used a mainframe was the last time you used anything other than cash to pay for anything. 😉

[@jacekruzyczka3058]

@@nubaus Yes, but you don't interact with it directly. Besides, many fintech businesses don't even use any mainframes any more.

[@MeriaDuck]

At a creative center, nowadays it would be called a maker space of sorts, there was a tiny basement with a computer running Unix comprised of nineteen inch rack components. To start one of the external disks the size of a washing machine you had to enable power, wait for the disk to spin up and finally toggle the physical read/write switch. Only the you could turn the key of the power to the CPU unit, and after a while two terminals (possibly adm3as) beeped and it was on line. Fun times😀

[@moshixmainframechannel]

Yes I did manage a similar computer at our high school. It was a VAX 8600

[@vbinsider]

Please bear in mind that three-phase power supply is the de-facto standard in Germany and nothing special as such. Most houses are provided with three-phase service. Having a suitable outlet for three-phased devices to be plugged in is a different story. But the usual IEC 60309 receptacle (commonly referred to as "CEE-Stecker") can often easily be installed. According to IBMs "Installation Manual for Physical Planning" the z9 is rated at 32 amps when powered by 400V 3-phased supply. That adds to up to 22 kW of power which is actually a lot, though.

[@moshixmainframechannel]

Thanks

[@gilsonvidal1]

Awesome Video - Learned a lot. I am going back to mainframes after many years away.

[@uswcboy]

I noted the power was stated at 900W; I think that is under 9kW is what I believe the answer should be, which at 400v (German spec 3-phase) which would be 12.99 rounded to 13Ampere @400VAC (3phase). which at 9kW - at roughly $.10/KwH - it would be like running two large 4/5TON central air conditioning units at the same time.

[@moshixmainframechannel]

Sounds about right

[@SuperHPaulo]

Wonderful video and experience (feel like a jet fighter pilot on take-off on startup), amazing video!!

[@StringerNews1]

Nice. I worked in an office outside of a mainframe room, and in the store room was a very large and very heavy rotary converter for the Amdahl computer. 60 Hz 3-phase (480V IIRC) came in, 400 Hz 3-phase came out. Had I not read the schematic on the info plate, I would not have guessed that there was a couple tons of spinning parts inside.

[@StringerNews1]

@@billlewis9740 It must be just that. I know that airplanes use 400 Hz to save weight. And in a classic mainframe all those bipolar transistors are thirsty for juice!

[@27613James]

They were called motor generators. MG's. We had them on the 360 and 370 IBM at our community college circa 1975. We also had two of them to power a pair of our IBM 3084 MVS systems at the bank we worked at circa 1985.

[@27613James]

@@StringerNews1 Yes plus the motors can be made smaller and more efficient to run 50V 400Hz The disk drives made by Honeywell ran 400Hz, rookie was probing for faults, our mentor reminded him about the 400Hz, 'yeah I know'.....'OUCH' and some profanity later, he got his hand where it should not be with his other hand on the frame.

[@StringerNews1]

@@27613James That would make sense. Our '90s vintage DASD had SCSI RAID so it wasn't evident why 3-phase was needed. I can see how it could be a legacy of the big disk drives that needed AC power. In the '70s the only motor-generator I ever saw was in the trunks of my town's police cruisers, to supply plate voltage to the Motorola radios that were still serviceable after 20 years of use.

[@ByWire-yk8eh]

What does it do?? It runs software used by almost every financial institution in the world. They do all the back end processing. For example, most bank to bank transactions use mainframes. These systems are considered to be secure. Their rivals are Unix systems. (forget about Windows and Apple)

[@moshixmainframechannel]

Yes that’s what they do. Not sure they are really secure, or even more secure. IBM doesn’t report vulnerabilities found in z/OS, so we don’t really know how secure or not. But I don’t think it’s more secure then something like Linux because Linux has a lot of scrutiny and attention

[@douro20]

NonStop systems are still used in the financial sector as well.

[@douro20]

Don't forget that z/OS has a UNIX subsystem and that there are a good number of these machines which run Linux.

[@hellmen54]

Its stable, the uptime is great but its more insecure than a 13 year in puberty. There are many talks on mainframe hacking and their legacy really gets in the way of securing anything. It connects over a telnetish protocol, has an 8 alphacharacter case insensitive password limit (as in you can’t exceed it), … Mainframe security is mainly separating everything of the network and only allow very limited connection to it. The only “secure” thing about a mainframe is the fact that almost nobody knows how to use them. Its not unix, windows or even something resembling a normal pc. Don’t get me wrong I really love the big iron. The general way of working is amazing and a real look into 1970’s computing. But security was just not what it is now.

Well, I started IT in the 70s with a couple of 3033s and 168s. The power-on sequence was a little bit more exciting, with the big power shunts in the systems connecting first: "BANG", "BANG - BANG", "bang, bang, bang, bang", "tack, tack, tack, tack, tack", "BANG" and so on for about 10 minutes. The turbine sound started then afterward. Power-on, IMPL and IPL took about 30 minutes.

In the mid 80s I had a sharp 8 bit computer at home. I turned it on and the computer was instantly ready. I was so fascinated when at work an IML and IPL took easily an hour to CICS ready.
