      One must agree with Steve Jobs. They make amazing things but they can't sell them. The only things got close to object orientation are NeXT and OS/2 years later. Imagine saying "You will pay extra for a clock and bold capability"

      @@compu85 They also did a 386 'Compainion' box which replaced the emulation board. Two variants, 16Mhz & 20Mhz 386 processors.
      Used to know most of the VP boot codes & error codes off by heart.
      The dreaded 0951 = failed disk scavenge. If the machine goes into a scavenge (0950) to repair the disk pages, it can take a long time. If it results in an 0951, this means the scavenge failed and requires either a new disk or manual intervention.
      Network boot into expert mode, ( you need to know the special password ;-) ) you can then get bad disk pages and assign them to the bad page list.
      Once done, scavenge the scavenger volume, this provides more space for the main scavenge operation.
      Then run the main scavenge again (0950), it if is successful, VP will start up, recommend that you then log out and save desktop to a remote network file server.
      Change the disk, Install VP (we used to boot from net and install from an install server), boot and recover desktop from file server.
      The other one that was popular was 0149 - this is the disk not loading the microcode, often it was the 40Mb half-height Seagate disk where it's heads had 'stuck' to the platters, known as "sticktion". Pull the drive and give it a sharp rotation movement with the disk in it's verticle plane, you hear the heads go clunk, then re-insert and it'll boot up.
      The boards were quite robust, but sometimes they would fail. IO and Memory borads were the most common.
      Great video, brought back so many memories, looking after 1,000+ of these machines was a continuous task along with all the network storage, removable disks, clearing house and routing servers.

    This is a great demo of a very rare system in working order! But next time, please shoot video in 1080p or 4k, so that the demonstration can represent the screen and have less/no compression artifacts. It is unfortunate that the printing on some chips is blurry, and the screen heavily aliased, because this video is 720p.

    • @compu85
      @compu85  11 หลายเดือนก่อน +1

    Very interesting to see the little UI kludges and rough spots (e.g. the warning about waiting for a specific status code before power off; manual repagination hidden in a menu; slow graphics drawing at least compared to the Mac which was highly optimized for the 68k and other Macintosh hardware only) that, one assumes, might have been eventually improved in future versions if the product had been more successful. (Or, at Apple, Steve Jobs would have yelled at people until it was fixed before release.)

      Many! The most changed item were the screens. We’d change 3-4 a week. You can have fun with the screens, you can flip the X and Y plate connections, it’ll turn the image upside down and back to front.
      The air inlets would get clogged with dust. Heads in the disks would get stuck, a shake of the disk is required. Saved a few desktops data from loss by using the advanced tools to add bad pages and scavenge the volume. All the systems were connected to a network, big thick co-ax where you had to tap a new connection live. If you got it wrong that entire network segment would go down. We also had the 386 companion boxes. Could be run independently or attached to a 6085. Used to know most of the boot codes off by heart.
      Keyboards were another issue, usually coffee, but there was a trend for metallic nail varnish, flakes of it would get into the keyboard and short circuit keys.

      Also used to maintain the 8010 systems file servers and removable storage systems. Changing and realigning the heads by hand, all 20 of them. Also saw some of the newer 8090 systems and Sparc IPX boxes. Trained on all of the aspects of XNS, clearing house servers, routers etc. It was a great grounding for networking. We also introduced 10Base-T, Cat 3 and fibre networking. Dec VMS, MS-Dos all co-existing.

    Shame on you for letting that 6085-1 controller get up on the table.... ;)
    There was the 15" version monitor as well, but....
    The later 19" monitor (of which I own one) has a power switch-volume control as well as the brightness control, and a green led in the front with three right angle grooves/slots.
    Personally, I'd wear a anti-static wrist strap handling those PWBs.
    There was also memory and firmware/software expansion to upgrade the 6085-1 to be a XPIW (Xerox Publishing Illustrators Workstation). The XPIW Logo was drawn from dots until completely visible which was superimposed over the bouncing keyboard.
    The 40mb HDDs were notorious for not starting up! Curious there is a LED on the C7 slot back plate. The 80Mb Micropolis did not have those.
    I have few of the those TRW Systems power supplies.
    The HACK version of Quick Restart would also freeze the time and date, sigh....
    Cold start up time which depends on how many software modules were set to auto-start could be up to 20 minutes. The practice around Xerox USMG in El Segundo was to reboot the workstations when we all went to lunch at noon. This was done to recover page space.
    Too bad you could get your hands View Point version 2.2. It had many additional features. At the time I was trained it was the current version installed in 1989.
    On floppy I have the templates for Xerox inter office correspondence and the Xerox logo font.
    Place about 10 clocks on the desktop all with second hands showing to see how much the screen refresh slows the system down, hehe!
    I used the PC emulator in my 6085 for online dial-up chat. For some reason it would randomly freeze then requiring a full system restart.
    When you login, if you watch the icons appear in alphabetical order :)
    Basic Graphics and Free hand are always drawn upon opening in the same order as original. You could also do simple animations as well.
    Paginate cleans up the edits (making the file contingent) and reduces it's overall file size.
    There was a System Loader HACK which took you one level deeper into the system. You could then remove system only software modules.

    • @DandyDon1

    • @DandyDon1
      @DandyDon1 หลายเดือนก่อน

      I have many of the Xerox HACKS for the 6085 including VP Aquarium, the Brush DMTs, a messaging software module which resembles AOL AIM for sending text messages to co-workers.
      There was one additional HACKS software module which upon start-up showed the progress of the software modules as they loaded from the bouncing keyboard screen. With each hop of the bouncing keyboard you would see a text message superimposed over it showing "Loading *application* Starting *application* Done. I would then move to the next application start up progress.
      Xerox sold MANY of these systems to US Government and Education. USC had many 6085s. I was working at USC when the first 6085 model 2 was delivered.
      I don't know about you but I saw diagnostic code 0938 just before you powered if off. I wonder what the difference is between 0938 and 0939. Not sure if I have those codes explained my documentation anywhere....
      Some of the diagnostic codes you always remember.
