• 555 - afterthought

    Hi again Ed!

    Video tutorial (I would prefer text version) but I loved the comments, especially #4! https://www.element14.com/community/docs/DOC-95071/l/the-learning-circui t-72-how-to-generate-a-clock-signal-with-a-555-timer

    I had recognized my post and knew it was old; glanced at it again (my
    off-line mail reader does personal mail first and then back to the other messages) and noticed my old Q-dot-com address -- from my dial-up days.
    What was 'funny' is there were a couple of websites which refused to
    accept my address -- I think the single domain letter triggered an
    ugh-ugh. Um, it's very official and legit, assigned to me by the
    telephone company, Qwest. Anyway, that incident was what prompted my to
    look around for secondary address that was free or at least very
    inexpensive and found GMail.

    The good thing about a BBS message is that someone who likes messing with older electronics can find old messages that will answer questions they have.

    Myself, I waited until many others who bought their Windows XP computer before I choose to buy one to use.
    I got mine in 2006, don't remember when they were first sold but I'm sure 2006 was prob more than a year after they started being sold.
    You are someone that remembers when they came in the Store You worked at.
    The XP was a upgrade for the 486DX33 DOS 5.0/WIN 3.1 I had been using.

    XP came out late 2001. So you were even more laggard than me. :D

    In 2006 the Pentium 4 was a bargain and the Core2Duo was out, more than
    enough horsepower for XP.

    Hi Ed!

    messing with
    olderelectronics can find old messages that will answer questions
    they have.

    That's true! Also sometimes handy when looking up stuff with search
    engines, but I also get a lot of old/antique returns which won't work
    because it's giving me a reply relevant to an old operating system and I
    need it for a current one. ...Seems like there could be switch to
    ignore old years and so allow only a current but that would exclude our scenario with a current response to an old post. Or 'The Post Which
    Never Dies': started in 1985 and is still current with minor
    alterations.

    I also don't usually jump on the bandwagon, rather preferring to wait

    plan for it. Guess the best example right now is have available PCI and
    PCIe slots for adding daughtercards for new options or expand the
    current ones.

    Your mention of Pentium 4 caused me to think of the original Pentium that couldn't add 2 plus 2.

    So You were on the bleeding edge getting a XP box.
    Shortly before AIO Printers/Scanners were sold I REALLY WANTED a Scanner.
    I paid a few cents less than one kilobuck (USD) for a 14 inch HP scanner and enjoyed it 1 or 2 years until I visited a friend and saw their AIO that they paid <>$300.00(USD) for.
    Now AIO's are much cheaper.

    Alta Vista was the first Search Engine I used in 1996.
    Then Search com , yahoo, maybe others until I began using DuckDuckGo.

    When searching for old computers maybe mentioning the Operating System would help.

    The newest computer here has Vista OS.
    Oldest is C=64 I got in 1984 .

    Nothing so simple. It happened only under very rare and specific circumstances.

    https://en.wikipedia.org/wiki/Pentium_FDIV_bug

    If you were crunching a pile of non-integer numbers, where
    ten-thousanths were significant, it could accumulate to enoiugh to throw
    off the calculation, but ordinary users never saw any effect.

    People like to rag on the Pentium, but AMD was much worse. I compared
    errata sheets for Intel and AMD and AMD had 4x as many problems. The one
    I ran into was that a 32bit CPU could only run the bus at 16bit speeds, cutting system performance in half. I saw that again with AMD's early
    64bit CPUs that could only run a 32bit OS. Windows will downshift but
    linux pukes it back. And they knew about it the first time, I knew
    someone who ragged on them til an engineer showed up and told him the
    problem and replaced his bad CPU. Otherwise they've never admitted to
    it. HP knew about it too, I think, because they sold PCs with this bad
    CPU with 32bit Vista instead of 64bit. And aside from the memory
    limitation, a 64bit OS is waaaaaaaaaaay faster than the same OS in 32bit.

    So You were on the bleeding edge getting a XP box.

    Actually I downloaded XP from one of the Usual Suspects, just to take a
    look, but I liked it and I still use it. For a long time it was a dual
    boot on what was originally a WinME box that I'd built 2 years before.

    Shortly before AIO Printers/Scanners were sold I REALLY WANTED a Scanner.
    I paid a few cents less than one kilobuck (USD) for a 14 inch HP scanner and enjoyed it 1 or 2 years until I visited a friend and saw their AIO that they

    I bought one of those good HP SCSI scanners off eBay for something like
    $30 back around 2002 (it was the first thing I ever bought there). It
    was so much faster than a parallel port scanner it wasn't funny -- 30
    seconds vs 15 minutes. A few years later I got another of the same model
    for free. Now I have an Epson Perfection someone gifted me, but way less
    use for a scanner.

    paid <>$300.00(USD) for.
    Now AIO's are much cheaper.

    The problem with the typical all-in-one is that the scanner is
    relatively poor quality. Back in the day many would only do 150dpi when
    300 or 600 was standard for standalone scanners. I have a somewhat newer
    AIO and it can't be convinced to scan at better than 150dpi. Which
    really isn't good enough.

    Alta Vista was the first Search Engine I used in 1996.
    Then Search com , yahoo, maybe others until I began using
    DuckDuckGo.

    I can't recall what the first search engine I used was; seems like most
    of my on-line time was BBSing and since the questions I had were electronics-related was easier to ask people, plus could get specific
    answers for my situation.

    When searching for old computers maybe mentioning the Operating
    System would help.

    For me (or my thinking!) does and doesn't help; my current batch of
    questions span several OSs: 'Linux > Ubuntu > 24.04/Noble Numbat' but
    the problem may have been resolved with 18.04, just I never had it until
    now. I should experiment with other search engines - Google might be
    good for certain types of searchs but DuckDuckGo for others. Just a
    matter of getting accustomed to a new one.


    The newest computer here has Vista OS.
    Oldest is C=64 I got in 1984 .

    Newest computer here is a Raspberry Pi 5, oldest is a DEC Rainbow 100
    which was the first computer I owned -- 1983??

    I got out of Windows because of the cost and a need to better understand
    how the underlying OS for MythDora worked. MythDora was a utility to
    record TV shows -- think TiVo on steroids. Was based on Ubuntu, so
    started playing with that and liked it. Ky will probably tell you there
    are better branches out there, and I'll agree, but for me a lot easier
    to know all my computers run essentially the same OS. The current
    MythTV (MythDora died off years ago) is an add-on utility as far as I
    can figure out based on Ubuntu but can also be run under other branches.
    For me a lot less of a problem to install on what it was made for,
