      Hi Bill,  There are several sites that talk to the ES7000 capability and LINUX.  Here is one http://esj.com/enterprise/article.aspx?EditorialsID=1074   I was very proud and thankful that I had a chance to work with this system – I started on the project 1997 and we delivered 1st piece  1999.  It is an amazing mix of  capabilities and includes LINUX as one of the primary platforms.  Interestingly it can run several different OSs concurrently with dynamic partitioning on an INTEL platform and exceeds mainframe performance. 

       

      It was my last job with UNISYS and I elected to leave the company rather than move to California and spend most of my time with off-shore manufacturing.  I really would have liked to stay with the project but family comes first.

      Ray,

       

      I knew Burroughs offered Unix, but didn't know they also had a Linux offering. My Unix training was done at Penn State 's Great Valley Campus at Valley Forge , PA. One of my instructors was a Unisys, actually Sperry, old timer who supported Unix on their various systems.

      Hi Bill,

      I agree that the big guns need and offer LINUX, Burroughs/UNISYS also offers it on the ES7000 and a few mainframes and it is a superior OS in the big machine arena.  I participated in qualification testing of LINUX on the ES7000 and it was very easy to port onto a 32 way Intel platform with a custom memory and I/O chip set.  I didn’t mean to give the impression that it was less of an OS, it is just that I don’t think into will make it into the average household anytime soon.

      Ray,

      As an old Burroughs guy, you probably don't want to hear this but Linux has some support from a big gun. IBM offers Linux on their mainframe systems. Even though I too am an old Burroughs guy, I think that is pretty big gun support.

      Hi Terry,

      Thanks for putting this in the proper perspective - I agree on everything you have said except for one thing.  I have been watching LINUX try to grow to a full blown OS for many years and while it is superior for specific characteristics I don't think I will hold my breath until it matures.  I have my doubts that it ever will - it seems to lack the management drive that it takes to make a single entity that does it all.  Right or Wrong if it can't at least do what MS OSs (including device support) do then it will never be a big box competitor.

      I hope I am wrong about LINUX because I truly believe it could be king of the hill with the right direction, management and stability, but that has yet to happen.

      Regarding SDR on older computers: try simultaneously running a
      graphical user interface, and the DSP code necessary to decode and
      display CW or SSB on a 386 or 486. Without a dedicated DSP chip, you
      are in for a long wait. Over ten years ago, I wrote DOS-based code
      (in Turbo-C) that displayed an audio spectrum analyzer in a DOS-based
      VGA graphics display. All the DSP was done in either a homebrew
      Motorola 56000 board, or an EVM, with DMA data transfers over the old
      PC bus (homebrew), or fast serial port(EVM).

      I don't want to do that again. But, if you are staying DOS or Win-
      98, kiss the PC doing DSP goodbye. I still have three Moto 56000 EVM
      boards that I'd be glad to sell.

      Regarding Linux: There is some movement afoot there with SDR. There
      are a few programs that will work. Again, you must do a hardware
      upgrade to get the processing necessary to do DSP and on-screen
      graphics.

      I also have a couple 486 computers with Win98, and Win95, and DOS.
      Just in case I ever want to run my 56000 audio spec analyzer.

      But, I also have a working IBM 5-slot computer, and a spare.

      And, I have a working IMSAI CP/M system with Heath H19 terminal, and
      8-inch drives. I boot CP/M and run Wordstar every once in a while.
      How about a nice game of chess? Or the CP/M user-group Adventure?

      I also have two Altair 8800s, and an Altair turnkey (no front panel),
      plus a bunch of S100 boards. No power to them in about three years.

      I don't expect these computers to run SDR software either.

      And, I can still erase and burn 1702A to 2764 EPROMS. Go figure.

      Don't get me started with software. From CP/M, to DOS 1.x to 4.x, to
      the original flight simulator. I even had the paper tapes for Altair
      4k and 8k Basic. Anybody remember Lattice C, or Run-C? Or the CP/M
      Pascal?

      But native SDR on a 4MHz Z80? Probably as likely as on a 266MHz 486.

      Terry
