  2. Belkin sells a converter for around $30.00 and works well

    Those are legacy ports and will not be on ANY laptop in the near future

    The other option is get ahold of and see if they still have
    any of those old bullteproof Toshiba laptops.

    yea, I have one of those old toshibas that works good butneed a newer
    operatingsystem for some software. prob cheaper to upgrade to win 2000 than
    get a new laptop, kinda wanted a new one. as slow a win98 is on that
    tecra I wonder how win 2000 would run on it? hate to spend much on an old
    used laptop upgrade.

    Try something like this:

    I've run into a couple machines recently that the PS/2 ports have simply stopped
    working on... these little gems have saved the day.

    I have an old Toshiba Satellite... Pentium 90... runs Windows 98SE quite nicely.
    Has about a dozen serial ports! (Just kidding).

    The Dell Latitude D620 still has a serial port, see

    however it lacks a parallel port (the D610 had both).

    Also be careful that whatever laptop you buy still has a PC Card slot,
    as many newer models have dropped this.

    You may want to buy a CardBus serial port card as opposed to a USB
    adapter. The CardBus card will work in more situations than a USB
    adapter, depending on the program and the O/S.

    I use the Startech CB2S650

    Often the picofuse on the +5V line will blow. It's replaceable if you're
    good at soldering.

    One thing to consider, if you don't want to spend the $900 or so on a
    Dell Latitude D620, is that there are a lot of D610 Latitudes on the
    used market. They will come with the balance of the Dell three year
    warranty, and you can transfer it on-line. I prefer the D610 over the
    D620 because the D610 also has a parallel port, and it has the

    I also use infrared, and many manufacturers have dropped IR support. I
    was never a big Dell fan, but I bought the D610 in desperation, needing
    a laptop with a serial port, parallel port, and IR, and not wanting
    external junk hanging off. Also, I need to run Linux sometimes, and need
    the serial and parallel ports to work, something that would be unlikely
    to happen with a USB to serial port or USB to parallel port converter.

    There is no requirement to remove them. Most manufacturers have removed
    them from consumer level laptops in order to save money and space, but
    on commercial laptops several manufacturers continue to offer legacy
    ports, and will do so for the foreseeable future. Dell (d620), HP
    (nc8430), Fujitsu (E8110), Toshiba (Tecra M5) are popular products for
    business and commercial use where a serial port is still required, and
    where a USB to Serial converter will often not work.
  17. I didn't know that.

    Or much of anything else, apparently.

    everything...what was it? was it "bond".....LOL

    even me I was able to recognized the Declaration of Independence....And I am

    There is that... but $25 for an adapter is a lot cheaper and easier than an hour
    or more of my time to pull all the cards, remove the board, desolder one fuse,
    find an appropriate replacement, solder it back in, and reassemble everything,
    and pray that that was the actual fix :)
