    I started working for Philips Data Systems in Apeldoorn March 1969. First they did send me on a service engineer's course for the Philips P1100 main frame. Afterwards I had to test the prototypes of all data communication equipment with a hardwired BSC type of protocol for the P1000 main frames. We connected; numeric keyboard/card reader for warehouses; a display 24x80 chars; a typewriter/matrix printer; a 16-bits HP mini computer and a Philips Office Computer. While following a 3 year University course (2 evenings/week) on software engineering, I switched to OS development in 1974.

    Unfortunately, and as is often the case, we have a manufacturer that puts a spin on history, and for the less knowledgeable, effectively attempts to rewrite the history books . The first commercial computer in fact was British LEO ( Lyons Electronic Office) I. Probably the most advanced mainframe of its day was the range of computers produced by Burroughs. From the introduction of virtual memory through reentrant code to a single pass COBOL compiler. All of this with a stack architecture and no Assembler. The OS was written in an Algol type language!

      +Alan Marshall - Yep System 4 a variant of RCA Spectra 70 series. Interestingly Sperry Univac's 9200/9300 series was a clone of IBM's 360/20 (16 bit) and their 9400 used 32 bit IBM 360 full instruction set. Again an IBM 360 clone. Wang's VS also used IBM's 360 instruction set. I wrote a lot of BAL at one time - A really cool assembly language with storage to to storage instructions. The 360/20 was off course phased out and replaced with IBM's System/3 and RPG II was born together with 96 column cards!

    Two points I want to make:
    1) vmWare has a virtualization system that allows companies to horizontally and vertically scale up java-based artifacts especially with Dell hardware with almost no to very little interruption. The problem is data centers that start increasing their leasing fees to almost a million or more USDs per year. Then management starts pressuring the IT staff to migrate everything to a cheaper data center company. And, folks, data center migrations are NOT interruption-free!
    2) Cisco's server-room-in-a-metal-box UCMS can become a costly Single Point Of Failure (SPOF) if it erroneously decides to auto-upgrade itself. And no one is confident enough--including Cisco support staff!--to try and figure out the problem because the management software is nearly incipherable. Any middleware that requires its own buzzwords and adherance to a complex framework that can only be learned in a classroom is doomed to failure. ESXI, the freeware version of vmware's ESX, helps harried and overworked System Administrators (like I used to be) battle the learning curve while on the move to further improvements. So if a middleware company wants to stay maintenance friendly, they gotta provide a free version of their wares that encapsulates their core features.

    Back in the late 90s, I was an OS/2 product specialist at IBM Canada. OS/2 also had virtual machines with the DOS & Windows subsystems. While most of my work was on ThinkPads, I also had accounts on several VM systems. While I was there, they encouraged us to work with Linux on company time. However, this was not my first experience with virtual machines. That would be on VAX 11/780 systems, which I worked on in the 80s.

  • @typograf62
    @typograf62 Před 9 lety +4

    So true. The mainframe (and btw the AS/400) is simple, reliable and cost-effective. As for security that depends on a lot of things. A few years ago hackers or one hacker stole a lot of very sensitive information from a Danish computer center, from a mainframe. They do not even know today if critical information has been changed as logging was disabled by the hacker. That could have happened on other systemes also, perhaps more easily.
    I miss working with mainframes. I work with a lot of servers and a lot of the trouble is finding out where some order or other critical information has ended up when it did not reach the supplier? There are far to many things to forget or change (of course nothing has been changed ...).

    • @VicNorth2023
      @VicNorth2023 Před 8 lety +2

      +typograf62 AS/400 was a different animal to IBM's Mainframes. The architecture (IBM System/38) was originally supposed to replace the classic DOS and OS of their 360 range. Originally a spooler was not part of the OS for IBM's 360 range and we used products such as HASP and GRASP (later POWER). Jobs would run in partitioned memory: F0 , F1, F2 and BG which was allocated by running a Sysgen which required taking the system down and running job streams which amounted to a couple of trays of 80 column cards and therefore we could not dynamically change a partition size.. Also included in a Sysgen was setting up libraries etc. The whole IBM approach with mid range was to ease the tasks normally associated mainframes.

    It was so cool how they overlaid the supposedly important speech with elevator music that made it hard to hear and repeatedly used the same unexplained black and white photos to represent multiple disparate concepts. It was very interesting hearing an endless number of people briefly refer to some obscure system they worked on without explaining what that meant or how it differed from anything else. What a lazy and pointless public relations style "documentary" that never goes beyond barely scratching the service.

      Back in the mid 70s I was working on a system called TRACS, which managed freight train consists for Canadian National Railways. The Datapoint 2200 terminals, which it ran on, were supposed to use the Intel 8008 CPU, but it didn't have enough performance, so they rolled their own with discrete logic ICs. This system ran ASCII internally and to the printers, but also used Hollerith code to the card punch and reader, Baudot to remote printers and EBCDIC to the IBM mainframe computer in Montreal. That's 4 different codes on the same system.
