  • Digital Archaeology: Dell Latitude E5500

    The Latitude line has traditionally been Dell’s business line of laptops with the Inspiron line targeted towards the home market. Though they are cosmetically different, they often share a lot of the same hardware internally. The Latitude E5500, or at least this one, features a Core 2 Duo T7250 CPU @ 2 GHz and Intel Mobile 4 Series Chipset Integrated Graphics. Hightlights include:

    • CPU: Core 2 Duo T7250 @ 2 GHz
    • Memory: 4 GB DDR2 @ 800 MHz
    • Graphics: Intel Grahics Media Accelerator (GMA) 4500MHD
    • Screen: 15.4″ @ 1280×800

    More a more complete hardware inventory, check out the output of HardInfo.


    Like most laptop models, this one was available in a wide variety of configurations though they all would have had a Core 2 Duo variant of some kind. At the time it was released, this would have been a midrange configuration and it probably shipped with 2 GB of RAM and was upgraded later to 4 GB. This brings up perhaps the biggest limitation of this laptop (and chipset for that matter). While it has a 64-bit CPU, it is still restricted to a maximum of 4 GB of RAM. This takes away one of the biggest advantages of a 64-bit system….the ability to use more that 4 GB of RAM.

    The fact that this laptop uses an integrated Intel graphics solution rules it out for gaming, at least for games that were coming out at the time this laptop was relevant. Of course, the Latitude line was primarily targeted towards corporate use so for the most part such capabilities wouldn’t have been needed.



    However, in my opinion at least, the Latitudes of this era hold up better than the Inspirons in terms of styling. This model is pretty simple with its plain matte black look in heavy duty plastic. It’s nothing special but it still looks reasonably nice and holds up better physically over time than Inspirons of the same era.

    There seems to have been a couple of different keyboard designs. One includes a trackpoint and the extra mouse buttons to go with it while the other only includes a trackpad. Mine only has the trackpad but I prefer that anyway. One nice thing about this laptop is the variety of ports it has. There are four USB ports, firewire, headphone, mic, S-Video, VGA, Ethernet, PCMCIA and even a serial port. It still has an optical drive as well.

    As far as contemporary use, I think Windows 10 has become too much of a memory hog over the years with subsequent updates to really be reasonable to use with only 4 GB. However, it’s probably still tolerable if you were to replace the hard drive with an SSD. It works somewhat better with Linux though as long as you don’t go too crazy with opening tons of browser tabs. The 2 GHz Core 2 Duo processor is really still plenty fast enough for any typical office tasks and basic web browsing. And if you wanted to play older games (meaning a few years older than the year this laptop was released) then it is certainly capable of that too.

    Whenever I have this laptop turned on, it is of course running BOINC and participating in various projects. Having a 64-bit processor and running Linux, it can do work for all of the projects I participate in including Einstein@home, Milkyway@home, World Community Grid, Rosetta@home, Universe@home and Asteroids@home. You can see how it is doing overall at FreeDC.


  • Digital Archaeology: Floppy Disk #14 – COMPUTER.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 (sometime in the late 1990s to the best of my recollection). 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, most or all 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.

    The following 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 a modem and whatever terminal program you had available for your computer to dial in with. Many of these disks have forum messages, e-mails and chat session logs. All of this is pre-internet stuff and I am not aware of any archives in existence today that contain what was on Delphi in the 1980s.

    This post includes the contents of COMPUTER.DOC. This file is dated September 2nd, 1985 and is in a subdirectory called TELEPSYC. This is an article on types of computer addiction (“ego syntonic” and “ego dystonic”). No name or other credit is listed in the file. I tried doing a web search on a few strings from this article but couldn’t find anything so I’m not sure who wrote it. Based on the name of the subdirectory and the mention near the end of the file itself, I believe this article came from a special interest group or some other kind of feature on Delphi called “TelePsych”.

            COMPUTER ADDICTION
    
    It is useful to distinguish between "ego syntonic" and "ego
    dystonic" computer addiction.  These are useful psychological
    terms to add to your vocabulary anyway.  Ego syntonic computer
    addiction means you don't honestly think you have a problem
    but other important people in your life do think so.  Ego
    dystonic computer addiction means that you really feel you
    have a problem but you don't feel you are able to stop.  This
    distinction can be usefully applied to quite a variety of
    human problems such as drinking, philandering, even violence
    and aggression.
    
    Ego Syntonic Computer Addiction: 
    In this case you just like hacking but you have been advised,
    perhaps angrily, either that you are wrecking your life,
    greatly disappoining someone else, or both.  Start with a
    brutally honest self assessment.  Think hard about the
    following questions, and write down your answers to each one:
    
    1.  Do you have a history of finding gadgets and games more
    interesting than people?
    
    2.  Do you prefer solitary activities to ones that involve
    interaction with human beings?
    
    3.  Are you highly compulsive?  That is, do you often have an
    overwhelming need to work on some project in spite of commmon
    sense?
    
    4.  Are you using computer activities to escape from painful
    problems?
    
    If the answer to all four of these is a definite "No"
    (assuming you have some measure of accurate self awareness),
    chances are your habits and preferences happen to clash with
    those of some of the important people in your life.  Just to
    make sure, why don't you try asking some people whose opinions
    you respect to answer these questions about you.
    
    If you answer yes to one or more of these questions you need
    to do some hard thinking.  These tendencies are not
    necessarily indication of a serious psychological disturbance,
    but they have risks.  A lifetime of withdrawal from human
    relationships can lead to severe and intractable loneliness 
    and despair.  Withdrawal can be self perpetuating.  As people
    skills decline from lack of practice, human relationships
    become more and more difficult and there is more and more
    impetus to keep withdrawing.  If you have some of these
    tendencies but you do not feel you really have a severe
    problem you must set some goals regarding how much time and
    energy you want to make available to the important people in
    your life as well as to your non-computer responsibilities.  
    It might help if you asked someone to help you monitor this
    committment and remind you if you deviate from it.  If you
    feel you have these tendencies to a more severe degree you
    should seek professional consultation.
    
    Ego Dystonic Computer Addiction:
    You know you hack too much, but you feel you can't stop.  This
    is probably similar to a gambling addiction.  Hacking is a
    process of prolonged concentration and frequent frustration
    that rewards at unpredictable intervals, promising but never
    quite delivering great satisfactions (just like gambling). 
    This can be an insidious but powerful set of circumstances. 
    It gets even more compelling if you are depressed or escaping
    from painful problems.  There are no simple answers, but try
    these out:
    
    1.  Take a computer vacation. Unplug the equipment and take it
    to a friend's house for two weeks.
    
    2.  Schedule a couple of computer-free days every week.
    
    3.  Keep a journal of your feelings and private thoughts. 
    When you "get the urge" to hack, you may really be avoiding
    dealing with them.  Try facing them directly as possible by
    writing them down.  It probably won't be as painful as you
    expected.
    
    4.  Expand your repertoire of pleasurable activities.  Make a
    list of non computer activities that might give you pleasure
    and commit yourself to spending time on these instead of
    hacking.
    
    In either case, don't hesitate to seek help either from a
    mental health professional in your community or from TelePsych
    if you feel you are losing the battle.  Self help has its
    limitations.  The price of delaying could get pretty high.  
    

  • Digital Archaeology: Dell Latitude D610

    The Dell Latitude D610 is a Pentium M based laptop that was a slight upgrade to the D600. While looking nearly identical, there are enough internal physical differences to make swapping parts like the motherboard, LCD, Keyboard, etc. between the two impractical. You can see the specifics on the D600 here.

    Some improvements over the D610 had over the D600 were a sturdier chassis thanks to a more solid frame, moving from the 855 chipset to a 915 based chipset, DDR2 RAM vs. DDR, and faster processor and graphics options.

    This particular D610 seems to be one of the lower end version in that it is using the integrated Intel graphics version of the motherboard as opposed to having a discrete card and only has a 1024×768 display as opposed to the 1400×1050 display that was also available. Specs include:

    • CPU: Pentium M 740 @ 1.73 GHz
    • Graphics/Chipset: Intel 915GM
    • Memory: 1 GB DDR2 533MHz
    • Display: 14.1″ @ 1024×768
    • Hard Drive: Hitachi DK23FA-6 60 GB Ultra-ATA 10 4200 RPM
    • Optical Drive: Phillips CDRW/DVD SCB5265
    • Ethernet: NetXtreme BCM5751 Gigabit Ethernet PCI Express
    • Wi-Fi: BCM4318 AirForce 54g 802.11a/b/g PCI Express Tranceiver
    • Modem: 82801FB (ICH6 Family) AC’97 Modem Controller

    For more detailed specs, see the output of Hardinfo here.

    There were two basic variants of the Pentium M. The first, code named Banias, featured a 130nm process and 1MB of cache. The second, code named Dothan, feauted an 90nm process and 2MB of cache. Both variants came in various speeds and had processors that ran on a 400 MT/s bus and 533 MT/s bus. The Pentium M 740 in this laptop is a “Dothan” variant, runs at 1.73 GHz with a 533 MT/s bus. The extra cache and faster bus really makes a difference in how snappy they feel.

    The Intel 915GM chipset includes PCI Express capability, support for DDR2, support for a 533 MHz FSB and updated Intel graphics. Unfortunately, this chipset supports a max of only 2 GB of RAM.

    This laptop is somewhat upgradeable. The most immediately useful upgrade would probably be to max out the RAM at 2 GB. The processor could also be upgraded. The fastest Pentium M, the 780 @ 2.27 GHz will work but may run a bit warm. It’s probably safer to stick with the 21 watt processors (vs. 27 watt) in which case it could be upgrade as far as the Pentium M 760 @ 2 GHz (or Pentium M 765 @ 2.1 GHz but this one runs at a slower bus speed). An SSD or even just a faster mechanical hard drive would probably make a pretty big difference in speed as well. At the end of the day, the chipset limitation of 2 GB of RAM is probably the most significant limitation.

    This laptop was designed with Windows XP in mind and that is probably still the best version of Windows for this machine. It could probably run Windows 7 32-bit but I’m not sure it would be worth the effort. If you want a more modern OS, then Debian seems to work fine and Debian is perhaps the only major Linux distribution still doing 32-bit releases. Debian is working reasonably well even with only 1 GB of RAM but probably not for much more than basic office tasks and very light web browsing.

    Like all of the computers that pass through my hands (at least the ones that are capable), I run BOINC on this laptop. Of the projects I participate in, this machine has gotten work units for Einstein@home and MilkyWay@home. It has also gotten tasks from World Community Grid but that project has been down for a while now. Many projects don’t support 32-bit CPUs these days. You can also check out its BOINC stats on BOINCStats or Free-DC.
