    I know you have to make sure the battery is in the computer before it will
    boot. Does anyone know of a way around this? I have a toshiba lap top that
    is about 5 years old, and it won't boot. I did try a friend's battery and
    it worked then. I am blind and will have to get someone to check the
    voltage on the power supply and make sure we have voltage on the terminals
    on the computer also. Bet some of you guys have had this problem before.
    E-mail me back to this address if you can help. Located in Georgia and
    have unlimited long distance. Not verry good at typing out the problem.

    I do not know what model you have, but I trust you are aware of the
    problem that some Satellite models had with the power connector jack??
    List what model you are dealing with and perhaps someone can help. The
    model I have will power up and boot without a battery if you use the
    power adapter to power the unit. If yours will not, it could be that is
    why your battery is bad and swapping another from a friend worked.

    Its probably easier for blind contributors on Usenet than practically
    anywhere else on the www because of all the bloated sites /frames / flash
    mangling and obscuring whatever info is buried in there. Usenet having
    started with test-only terminals and 400 baud or so modems.

    Are there stand alobne DVMs with voiced output ?, pc scopes with descriptive
    text ?
    I imagine there are electronic repairers with poor sight , but are there any
    blind repairers ?

    <frown> This was uncalled for.

    Sight isn't necessary to interact with a computer.
    Especially in a forum like this -- devoid of useless graphics, etc.

    It is unfortunate that so many devices that we interact with
    on a daily basis take sight -- as well as hearing -- for
    granted, needlessly. Think about what's around you and how
    you would interact with it if you were visually impaired;
    or hearing impaired; or suffered from tremor; or any of the
    dozens of other problems that many folks deal with every day
    (if you live long enough, you *will* go blind *and* deaf!)

    I spend a good deal of time dealing with -- and designing
    devices to be used by -- people with various disabilities.

    Let's flip your criticism of *my* comment around: can
    you explain any reason for *your* reply to the original
    poster -- besides wanting to see your name in print?
    Great! Maybe she and Dana can exchange life experiences
    and how they each cope with their specific issues!

    Exactly. Note that there are some (voluntary) standards that
    people can adopt to make "blind friendly" web pages, etc.
    (e.g., "Bobby Approved"). However, it is painfully obvious that
    most sites are geared towards the sighted.

    You will also discover -- should you ever try to use the
    "disability features" in your Mac/PC -- how clumsy these
    interfaces can be. Turn your monitor off and see just

    Maybe 300 baud? (400 isn't a standard baud rate)
    Yes. But then you need a speech synthesizer that has a serial
    port (DECTalk, DECTalk express, etc.). Or, nowadays, a speech
    synthesizer running on your PC tethered to the DMM, etc.
    Note that there is a difference between "legally blind" and "blind".
    Also, the cause of blindness and its relative onset in life play
    a big factor. For example, those blind from birth adjust differently
    than those losing their vision later in life from things like
    diabetic retinopathy (e.g., learning Braille in your 60's may
    just not be an option -- especially with the neurological
    damage that accompanies a disease like diabetes).
    Decades ago, I worked on the Kurzweil Reading Machine (a device
    that "reads books" to the visually impaired). At the time, it
    was implemented with a minicomputer (i.e., the size of a
    dishwasher) and a hand-built scanner (consumer scanners did
    not exist back then). It was not uncommon for us to talk
    a blind client through the process of disassembling the
    minicomputer to the point where boards could be reseated
    or swapped out. Nowadays, isn't that all *real* "factory

    This is one of the early symptoms of Myasthenia Gravis (I am
    not claiming that you have MG -- just drawing a parallel).
    But, with Bell's, don't you also tear a lot? I.e., so you
    almost *have* to actively close your eye to blink away the
    Understood. But even things like page format/layout
    can be confounding. E.g., trying to recognize columns (think:
    frames within a page) is very hard for someone not
    "seeing" the page.
    My point is that even *with* text-to-speech (TTS), it is
    very hard for most people to process information. Many
    people are highly visual oriented. And, have, after a lifetime,
    developed their skillsets oriented towards processing information
    in this way.

    Try, for example, to have a page of text *read* to you
    and see how much of it you comprehend afterwards. Then,
    realize that you can't just flick your "ears" back a few
    paragraphs to review what you heard "back then" -- which
    is something we constantly do with our eyes as we rescan
    text that has previously been read for clarifications, etc.
    Ah, cool! But, you still need a PC just to read your DMM.
    I.e., there is a big inconvenience involved. I get annoyed
    when I don't have enough room for my 5.5 digit DMM and have
    to resort to using a Simpson VOM just because it's smaller.
    (yeah, I really should buy an El Cheapo pocket sized DMM
    but it seems a waste when I have so many others...)
    <grin> Well, *technically* I can't drive without glasses, either
    but that's just because the law (here) requires vision corrected
    to 20/20 in order to drive. If I had to get to the hospital in
    a hurry and didn't have my eyeglasses handy, I'd have no worse
    problem than any other driver (especially those "handicapped"
    by having a cell phone glued to their ear!)
    20/200 is pretty bad. I know a gentleman who is in that shape
    now. At 12 feet he is effectively "blind".
    Hmmm... I thought gabapentin was for epilepsy? <shrug>
    IANAD so I'm just recalling things from memory. Maybe
    used for anything neurological?
    Yes, I was being facetious. My point was that a blind man can
    still do some checking and repair/replacement. E.g., "Can you
    verify that all of the cables are fully seated? Can you hear
    the scanner motor starting up and the carriage moving across
    the machine? etc."

    My experience with visually impaired individuals is that they
    have to rely on memory a lot more than sighted folks do. Whether
    it is remembering where something is on/in a device or remembering
    how to do something or remembering where they *put* something.

    I have found working with deaf people to be much more difficult.
    Sight is highly directional. So, we have other senses that
    compensate and alert us to things that are not in front of us
    (i.e., not in front of our eyes). Hearing being primary among
    them. Try getting a deaf person's attention if they are not
    looking in your general direction...! :-/

    Ah, OK. MG is a breakdown of the nerve-muscle junction.
    Think of it as the junction becoming "saturated" with use
    so that it no longer functions. Those junctions that
    can't "rest" to recover -- eyes, lungs, etc. -- eventually
    stop working (you die from suffocation with MG)
    I have tried to learn to use "audio books" just to get some sense
    of what it must be like. However, I just can't process things through
    my ears as well as my eyes. :< So, it is hard for me to relate
    my experiences to someone who is visually impaired.
    Just listening to a speech synthesizer can be an eye-opening
    experience to folks who've not had to rely on that technology.
    Your *ears* "get tired" (I don't know of any other way to explain
    <grin> Yeah, but then it would be one more thing to keep track of!
    At least the big meters are easy to find (they can't hide under things
    as easily as a pocket DMM)

    It does make you wonder how they can make things that cheap!
    For years, I've been reading street signs by "counting letters"
    and guessing at distinctive shapes -- "5 letters and looks like
    the first letter is round... probably Olive Street..." -- despite
    the fact that I have 20/20 corrected vision.
    An interesting corollary: if you have a vision restriction on
    your license and then have corrective surgery that restores your
    vision (e.g., cataract surgery), you *still* must wear your glasses
    in order to drive -- even though the glasses will now give you
    *imperfect* vision! I.e., you need to have your license updated
    to have the restriction removed before you can legally drive
    with your "new eyes".

    This makes *some* sense but is actually counterintuitive to
    many folks who have been down this road...
    Yes! :> A pair of (old) neighbors were deaf. When trying to
    get their attention I would resort to tossing pebbles. Always
    afraid that I would *hit* one of them, though... :<
    There are "all sorts". I was first exposed to that population
    as a teenager. I can recall asking a client that I had developed
    a friendship with: "What's it like to be blind? What do you see?"
    and, almost as soon as I had finished saying that, realized how stupid
    my question was. As a testament to how cool this guy was, his
    reply was, "Don, if you can tell me what *you* see, then I'll
    tell you what *I* see.".

    Of course, I still felt bad for askingn such a stupid question.
    But, it forced me to think about the problem and keep it in
    mind when I design things.

    For example, 1 in 15 men are color blind (to some extent).
    Ask your kids' teachers if they know that figure. In practical
    terms, it means that one boy in each classroom can't reliably
    distinguish colors. Do they know that when they formulate their
    lesson plans? "How many red balls are in this picture? How
    many green balls are there?"

    "Press the RED button to shut down the nuclear reactor in
    the event of a disaster. Press the GREEN button to restart it."

    A registered (not quite) blind person, I know, had great difficulty with
    locked-down sites with no text size change option.

    No one had told him about highlighting with CTL-A, then CTL-C and then CTL-V
    into a basic text handler , notepad/wordpad or whatever , where he could
    easily increase text size and more importantly use a negative script.

    Every now and then a poorly-sighted browser praises my gimmic-free pages on
    the www , just text and pics

    When we would install a Reading Machine at a new site, it
    was always "priceless" to watch the expression on the client's
    face as they first started using the machine. The synthesizer
    was *really* had to get used to -- the stereotypical "computer
    voice". You could see the client straining to make sense
    out of these grating noises coming from the speaker. The
    inflection was suboptimal, prosody was stilted, etc.

    But, there would come a point where you could *see* when they
    had started to understand complete sentences. Their eyes
    would literally "light up". You could almost hear their thoughts
    afterwards: "Now I can read ___________ without having to get
    someone to read it *to* me!"

    (Libraries carrying materials for the visually impaired had
    dreadfully small collections at the time. And, waiting
    lists for popular titles would often be *years* -- Braille
    is expensive to produce; synthetic forms are "hard on the
    hands". And, anything current -- like last *month's* news
    paper -- are almost completely unattainable due to transcription
    times and costs.)

    I can remember a client grinning that he would now be able to
    read Playboy (which seemed like doubly funny -- "Does anyone
    actually *read* those magazines?")
    The military used to place a special premium on color blindness
    ages ago. Most camouflage is easier for a color blind person
    to spot than for someone who is not. I guess the perception
    of color aids to the confusion of what the mind sees.

    Negative script == white on black. I don't understand why this
    is the case but this does seem to be easier for folks with
    *low* vision to read.
    For years, I used a text only browser to surf the web.
    Even now I disable images -- since most are just advertisements.
    Why waste bandwidth on something that benefits an advertiser?
    If I *need* to look at an image, I'll *know* which one(s)
    I'll need to see.

    This schematic was originally the negative form etched into a side panel of
    the first? miniature oscilloscope.
    This inversion of the original is much easier to read, size for size etc
    otherwise the same pic. Try saving to a graphics package and doing the
    negative of it
