  • Digital Archaeology: Floppy Disk #14 – ITSOVER.DOC


    A summary for those that haven’t been keeping up with this series:

    I found a number of 5.25″ disks at a thrift store a number of years ago (we are talking late 1990s probably). I finally got around to acquiring a 5.25″ disk drive and extracting the contents a several years back. Since then, I have been occasionally posting the content here.

    Based on the contents, at least some of these disks were apparently once owned by someone named Connie who used to run the “Close Encounters” Special Interest Group (SIG) on Delphi in the mid 1980s.

    A description of this SIG was found in a document on one of the disks: “This SIG, known as ‘Close Encounters’, is a forum for the discussion of relationships that develop via computer services like the Source, CompuServe, and Delphi. Our primary emphasis is on the sexual aspects of those relationships.”

    This service was text based and was accessed via whatever terminal program you used on your computer to dial in to Delphi’s servers. Many of these disks have forum messages, e-mails and chat session logs. All of this is pre-internet stuff and I don’t know if there are any archives in existence today of what was on Delphi in the 1980s. In any case, much of this stuff would have been private at the time and probably wouldn’t be in such archives even if they existed.

    This post includes the contents of ITSOVER.DOC. It contains a single e-mail dated December 10th, 1984. It’s one person’s opinion (going by the handle of FTF) of the sexual revolution and it is tied in to the topics discussed in the Close Encounters Special Interest Group. It looks like this was sent to three people including the manager of this particular SIG. Contents included below:

    Subj:   IT'S OVER!
    
    The sexual revolution is over!
    
    And I am not sure any of us can say who won...
    
    Sure, you say to yourselves, thats just a gimmick to get us to
    read more and perhaps that is part of what lies behind these
    words.  But consider, for a moment some concepts regarding
    trends of this sort. I certainly will concede that sex is
    alive and well in this United States and most certainly in the
    electronic world! 
    
    But it's different now for some reason.  Look at the types of 
    encounters that get discussed just here for example.  Loving 
    Submission.  Multiple person relationships.  Casual and quite 
    serious relationships.  The Main Event.  Even two years ago,
    would it have been possible on an individual level to discuss
    these events with such an open attitude?  I maintain it would
    have been difficult. 
    
    The sexual revolution was not so much an effort to make more 
    types of sexual contact acceptable.  Behind the closed doors
    of countless bedrooms the variations have always been
    occurring.  No. That was not the point of all of the front
    line actions.  The revolution has always been directed towards
    making us comfortable discussing it and engaging in it.  To
    take the word *dirty* out of what was already happening in the
    trenches. To let us say to ourselves first and later to others
    "You know,  I like sex!"  And then to go one step farther and
    say  "I wish my lover/friend/spouse would try this or not do
    that" and be honest about it.  To find the societal acceptance
    to be able to say that one does indeed have needs and desires.
    
    Of course with the greater awareness of the pleasures come the
    increased awarenesses of the potential dangers as well  - the 
    unwanted diseases - the greater risk of pregnancy - the fact
    that sometimes lovers aren't terribly honest about themselves.
    But those were always there.  We just didn't talk about them.
    
    The sexual revolution is over. I think we all won!

  • Digital Archaeology: Hewlett Packard xw4100

    The HP Workstation xw4100 was an entry level workstation featuring a Pentium 4 processor. Based on a bit of googling, it seems to have been a popular choice for video editors. At least I found a couple of generally positive reviews from video publications. This machine features:

    • CPU: Pentium 4 @ 2.4 GHz (Northwood)
    • RAM: 2 GB DDR-333
    • Video: nVidia Geforce2 MX400

    For more detailed hardware information, check out the reports from HWiNFO, CPU-Z or HardInfo.

    Early versions of the Pentium 4 earned a pretty bad reputation as being expensive, underperforming power hungry CPUs. They weren’t really much faster (and sometimes slower) than the Pentium III on a per MHz basis. The supposed advantage of the Pentium 4 was that it would be able to scale to very high clock speeds. It turned out that it couldn’t really do that either.

    Having said that, by the time the Northwood variant came along, the Pentium 4 had come into its own and if it couldn’t outright beat the competition (primarily the Athlon XP at the time), then it could at least keep up. By the time the hyperthreaded Pentium 4s came along during this same generation, Intel had regained their lead.

    For a Windows XP machine, a Pentium 4 is a great processor having plenty of speed for pretty much any game and fast for video editing too though at the time we were only talking about DVD resolution stuff. This machine has 2 GB of RAM which is plenty for most things. Windows XP can only see about 3.5 GB so it isn’t like you can go all that much further anyway. However, you could upgrade this machine to 4 GB if you wanted to.

    The weak spot in this machine is probably the Geforce2 MX 400. It’s a pretty low end card for this machine and I suspect that it may not even be what originally came with it. In theory, this machine could run a 32-bit version of Linux reasonably well (given its age anyway) but unfortuantely, neither official nVidia drivers nor open source drivers seem to support this card properly. It seems to be limited to 1024×768 resolution and the video refresh is really slow. In theory, a newer card would fix this issue.

    On the other hand, Windows XP still runs well. If you wanted to use it as a video editing machine for old DV stuff then it would be great. If you wanted to use it for gaming though, you would probably want to find a better AGP video card.

    Other than upgrading the video card and expanding the RAM to 4 GB (which would be especially useful for Linux), you could also upgrade the CPU if you wanted to. It should support at least a 3.06 GHz hyperthreaded Pentium 4. I currently have both Linux and Windows XP installed. However, utnil I get a different video card installed, I’ll probably stick to using Windows XP as it performs much better (and supports the proper resolution).

    Like all of the machines I use, this one has BOINC installed and is participating in various projects including Einstein@home, Asteroids@home and World Community Grid. These seem to be the only three of the six projects I regularly participate in that still support 32-bit. You can see how it is doing overall at FreeDC.


  • Digital Archaeology: HP Pavilion m7570n

    The HP Pavilion M7570N is a somewhat interesting machine. It was designed to be a multimedia hub and it certainly provided a lot of multimedia related functionality. It includes a DVD-ROM drive as well as a separate CD/DVD writer, a card reader that accepts a variety of media card formats, a TV tuner card, analog video capture capabilities, and of course firewire in addition to USB ports.

    Powering all of this was a Pentium D processor and 2 GB of DDR2 RAM. The one big deficiency was the lack of a dedicated GPU. However, that really only mattered for gaming and not the media oriented tasks this computer was designed for. Hardware in this machine includes:

    • CPU: Pentium D 915 @ 2.8 GHz
    • Memory; 2 GB DDR2 @ 266 MHz (533 MHz)
    • Video: Intel 82852/82855 GM/GME (integrated)

    Plus all of the above mentioned goodies. Check out the output of HWiNFO or CPU-Z for more detailed hardware info.

    The Pentium D was an interesting processor and it was a sort of interesting time for Intel in general. The Pentium 4 was nearing the end of its life as the Netburst architecture ended up being a bust (or burst?) because it couldn’t scale as much as Intel originally thought. At one time, it was thought that the Netburst architecture could reach speeds of 10 GHz. That didn’t happen and still hasn’t for that matter. the Pentium 4 HT and Pentium D were sort of stop gap measures as the Core 2 was being developed. The Pentium 4 HT mitigated the missed branch predictions of the long pipeline of the Pentium 4 modestly my adding an extra thread whereas the Pentium D stuck two Pentium 4 cores together. Both also added 64-bit extensions depending on the specific model.

    The motherboard is built by Asus. The HP model number is the Leucite-GL8E while the Asus model number is the P5LP-LE. It features the Intel 945G (Lakeport-G) chipset which was one of the earliest to use Socket 775. It was featured in a number of HP models including the Pavilion A1512X Desktop, Pavilion A1530N Desktop, Pavilion A1542N Desktop, Pavilion A1550Y Desktop, Pavilion A1560N Desktop, Pavilion A1613W Desktop, Pavilion Media Center M7500Y, Pavilion Media Center M7570N (this machine), and Pavilion Media Center M7658N. There does seem to be a fairly significant upgrade path. According to one random website, supported CPUs include:

    • Core 2 Duo E6x00
    • Core 2 Duo E4x00
    • Pentium D 9×0 Dual Core
    • Pentium D 8xx Dual Core
    • Pentium 4 6×1 series
    • Celeron D 3xx series

    There is a significant spread on possible front side bus speeds depending on the CPU including 533 MHz, 800 MHz, and 1066 MHz. It features a dual channel memory architecture with support for four 240-pin DDR2 DIMMs including PC2 3200 (400 MHz), PC 4200 (533 MHz), and PC2 5300 (667 MHz) DDR2 DIMMs.

    I recently looked at a 3.2 GHz hyperthreaded model and compared to that, this dual core Pentium D feels much snappier despite being clocked slower. The extra core really helps at least with more modern operating systems. You probably wouldn’t notice it as much with Windows XP for example. If this motherboard can indeed support up to a Core 2 Duo E6700 then that would nearly double its speed.

    The sticker on the front says “designed for Windows XP” and “compatible with Windows Vista”. Currently, Windows 7 is installed. As a multimedia center it was pretty nice at the time it was released, however, it became outdated pretty quickly both in terms of features and support. The TV tuner card is analog and doesn’t do HD. Driver support in Windows 7 was an afterthought and those drivers are hard to find. The applications that came with this PC for using the TV tuner card do not work in 64-bit Windows 7. I was finally able to find drivers and the card, at least for video capture, and it seems to work with VirtualDub. I can see how this machine would still be useful if you had any analog video capture needs. However, I doubt that the capture card that is in it would work with Windows 10/11 and I’m skeptical about it working in Linux as well.

    I’ll probably keep this computer around. It’s always nice to have a way to handle legacy media. In theory, I should be able to use this machine to capture VHS, 8mm, and other analog video formats. There are of course analog video options for modern systems, but what fun is that?

    Like pretty much any machine I turn on, if it is capably, I have it crunching tasks for BOINC. Despite the older hardware and OS, it can still crunch tasks for at least MilkyWay@home, World Community Grid, Einstein@home, Universe@home, and Asteroids@home and probably others.
