I know Dennis Ritchie died and maybe some of the others responsible for the UNIX Operating System, but what happened to True UNIX that I don't or can't figure out how to get a copy of it somehow ethically of course or find out how much it would cost to plan how to pay for it? Also, why was it such a craze in the 70's, 80's, and 90's in so many forms that I don't know about? I remember SGI and found out a few years ago about IRIX, but just recently came to relization of AIX and HP-UX a few years ago. I knew about SOLARIS because my Instructor in my UNIX/Linux classes would always talk about it and referece it, but I can't run it on my hardware because it's custom or I'm going to have a tough time because it's not an Oracle or Sun machine. Also, SGI is or did discontinue IRIX. I don't really want AIX or HP-UX and can't find prices on those either if I wanted them either. I don't know if I actually tried calling IBM or HP about pricing and not that long ago a few years back I read on HP's site that UNIX is legacy or becoming legacy. I vaguely remember seeing computers running it in the 80's or 90's at my dads work, which was a ford dealership as a really young child, but didn't know it or realize it might have been UNIX until I actually got to learn how to used Linux or choose to use some branch of BSD UNIX. How can I get Pure UNIX as in System V or whatever the last Version was, so I can see what it was like and maybe learn about it and actually experience why it may no longer be used or was discontined or died as an Operating System though. I may have asked this in the past or another thread, but I can't find it and I don't know if I got an answer if anyone knows. Also, I know it's a mainframe Operating System or was a mainframe Operating System, but I want to see if my server can run the latest version convert to C that is portable if it can and experience it. I don't want to modify it especially not without the help of the original UNIX community who knew what it should do or hack it, but study it and see where or what I can do with it if I can afford it or get it legally and figure out how to install it, like I did at least with FreeBSD and don't laugh PC-BSD that was already set to run after installation. PC-BSD is Good in terms of ease of use, but because I forgot or couldn't ffgure out how to enable myself as a sudoer in command-line or whatever I had a tough time with it. I was impressed by PC-BSD usb key feature though. However, somehow my the threads I started on FreeBSD's and PC-BSD's forums got removed, so I couldn't look up answers to question I had about how to become a sudoer either. I have a copy of PC-BSD though before the site shutdown or was having problems, but only up to 10.x something and I need the documentation for it as well to print it, but it's a real hassle fipping between a computer ready to connect to the internet and one that isn't anyway. I know they say BSD is true UNIX somehow, but I really want to try to see if I can experience True or Pure UNIX as in whatever it stopped at because I have a deep desire to satisfy a need to settle this somewhat curious or whatever in my mind as to what it must have been like using it or what actually happened to it? Also, I remember SGI being this huge craze around the time of Nintendo 64 or Ultra 64 in regards to IRIX, which I've asked about and am not inquiring about in this thread either. I don't want a mainframe like that kid or guy that got an IBM mainframe from a university and had a heck of time getting it in his parents basement or his either and if I did or wanted to make my own custom build I know I would need at least and Itanium 2 or newer that I can't afford while living in at least this apartment while receiving disability compensation and being in credit card debt from all the major purchases I made up until Spring 2016 and had to figure out how to pay it off because I was getting to far in debt and wasn't going to be able to do it again for years only paying minimum payments without working with a debt management company instead, which I am or have been since Spring of 2017 if not earlier. An expensive Operating System isn't desireble, but finding out What happened to UNIX and what it was like is to me for some reason. I'm using or plan to use it on a Gigabyte Socket 2011v2 board with two Xeon 2011v2's and 32 GB of DDR3 and and NIvidia Quadro 420 as my GPU, which should be plenty if it whatever the lastest Version of True or Pure UNIX doesn't require any more advanced hardware than what I've got. I'm using a 2U Supermicro case with 8 hot-swap bays and four 2 TB SSHD's two and it has an optical drive which redundant 700 watt Power Supplies I think. I had a Supermicro 4U Chassis with dual 1400 watt Power Supplies, but I couldn't safely Rackmount my Cisco Routers and Switches for Load Balancing type labs, even with what I call user a cheater u or the unmountable top of my open post frame server rack. I might use what I've dub my Ultimate Dual Xeon Build using an Asus Xeon 2011v3 board or Xeon Scalable or a Supermicro Xeon 2011v3 or Scalable with a Silver or Bronze processor and definitely not a $10,000 or say Xeon Scalable Platinum or somewhat lesser expensive Gold. though, which I can't find anyway. I don't think I'll use an equivalent AMD Opteron or EPIC configuration either, but AMD did have an extremely good high RAM option for the EPIC at 4 TB's though, but I probably wouldn't ever need or could afford that much RAM anyway or at least not at the moment until prices might go down. To be fair or competitive to AMD though Intel Xeon Scalable Option from Supermicro did support up to 2 TB as well, which the same situation would apply to AMD EPIC peak at 4 TB's according to Linustech tips of not needing or being able to afford it at the moment if ever. Also, Intel Xeon 2011v3 system from Supermicro can peak at up to 1.5 TB and Asus at 1 TB, but again would I ever need that much or be able to afford it and I think I plan to start with 128 GB at the most maybe for such an ambitious or hopefully capable enough system to plan and not an expensive memory kit either, which is all. Same for processors, graphics, card, and anything else needed or desired. All using a Lian-Li D8000 of course though for hopefully a true or close to mainframe experience if I need it, so I don't have to use my server and disrupt my networking lab too. Unless anyone absolutely feels I should try a possibly afford a current Itanium Solution that might still be support considering I thought I read on Intel's site if not somewhere else that Intel is or might be pulling the plug on Itanium. I already have the Lian-Li D8000, HD-DVD/Blu-ray Combo drives in, and memory card reader, but need the rest of the hardware to compete and want BD-XL drives if not internal tape drives instead of external. All while slowly paying off my credit cards in about 2 to 3 more years and one of them that I'm paying $250 a month to the debt management company to pay to pay off in about 5 more months, but if I stay at my apartment and continue attending the university I'm attending need to pay the interest an an insurance policy loan at least and maybe start paying interest on school loans again, which I can get out of paying back loans with student debt relief though if I have to. The idea to use the system that will go in the Lian-Li D8000 system steams from a long ago planned out idea for a highend workstation or graphics workstation that I decided I wanted to take on, but never finished and completes my focus on newer technology at a reasonable level and the goal was always to use the best affordable parts.
