    Those 9-tracks you're talking about could be stuffed onto optical (CD or

    That's *still* a lot of pain. By your argument I should copy my 3.5" DSDD floppies to 3.5" DSHD floppies because a new format is out because Apple is
    too brain-dead to maintain compatibility with older media formats on the new machines?

    To me that's just an argument for buying a used Mac as opposed to a new one.

    Given time, Apple will probably eliminate floppies entirely. So then should
    I transfer all my old files to Zip disk? Or CDROM? Or floptical? Or magneto-optical? Perhaps QIC-80 tape?

    Your argument asks the user community to spend a lot of time and money based
    on a guess as to which products are going to survive, when even the folks at Apple don't always have a clue (e.g. Apple III, Apple Lisa, Apple IIc+,
    etc.)

    Failure to *offer* minimal backward compatibility is the stupidity of Apple, not that of people who have a lot of media.

    Maintaining some degree of backward compatibility (or at least a
    provision
    for adding it) is reasonable enough, don't you think?

    No question, it's reasonable. But by the same token, is it reasonable to expect to remain backward-compatible with everything that's ever been
    done, however good, bad, or indifferent it might be? Especially when
    doing so will effectively "hold you back" from improvements that could
    have been added, if it weren't for the fact that you can't fit 'em
    inbecause you've got 429 flavors of legacy drivers already shoehorned
    into the code?

    Perhaps Apple should think about improving the operating system so that
    basic driver support doesn't have to be "shoehorned" into the code.

    IMHO the problem is not the inherent stupidity in eliminating the floppy
    drive, but in offering a 3.5" USB drive that doesn't support the same media
    as the drive it supposedly replaces.

    The labor involved is what makes it an enormous amount of work.

    I can see that possibly there is data on those tapes they could need,
    but I would think that with all the new ideas and innovations made
    in the past 10 years, most of that data would be obsolete. Wouldn't
    you agree?

    Actually, the opposite is usually true. Somebody comes up with a new theory about how A relates to B, etc. Then they go to the archived data to see if their new theory accurately predicts what happens.

    Think of all the Hubble data taken before it got a new telescope package.
    All of that data is 'blurry' and less useful than the data coming in today.
    But people invent new image processing algorithms every day. The data that
    is 'useless' today might be invaluable 5 years from now.

    Um, Apple eliminated the floppy drive from all their new Macs almost _
    five_ years ago. Apart from JWolf, no one really noticed.

    Perhaps Apple should think about improving the operating system so
    that basic driver support doesn't have to be "shoehorned" into the
    code.

    Mac OS X was, for the Mac at least, a completely new operating system.
    Apple had to add parts to OpenStep to turn it into a Macintosh OS. They
    had to decide which bits were worth rewriting for the new OS and which
    bits to leave out. As much as you or I would like to be able to access
    ProDOS disks directly, you can hardly blame them for leaving out support
    for a disk format for a non-Mac platform which hadn't been in production
    for 8 years.

    IMHO the problem is not the inherent stupidity in eliminating the
    floppy drive, but in offering a 3.5" USB drive that doesn't support
    the same media as the drive it supposedly replaces.

    Apple doesn't offer any 3.5" floppy drives at all. The only drives
    available are third-party ones. But again, the last Macs that only had
    an 800KB drive were made around 1990, so for the vast majority it isn't
    a problem. Unfortunately for _us_, we are the tiny minority who would
    like a drive that can read 800KB disks, but tiny minorities make for
    very small markets :o)

    NASA already did this, some 10 years ago. And it was about time: some
    of those old 9-track, 7-track and 5-track tapes had become so brittle
    that they broke during the handling, which caused some data loss.

    and stopped from deteriorating with little pain other than the

    That's *still* a lot of pain.

    OK, if you don't think your old data isn't worth the time to copy
    it to newer media, then it cannot be worth much. NASA had a different
    view than you, and did take their time copying their old tapes to newer
    media.

    By your argument I should copy my 3.5" DSDD floppies to 3.5" DSHD
    floppies because a new format is out

    You don't need to do that each and every time a new format is released
    of course. But when support for your older media becomes scarse, or
    when the media itself ages too much, then it's time to copy it to newer
    media.

    Personally I have some old date which have migrated to newer media
    several times: it originated on Apple DOS 3.2 13-sector disks, moved
    on to Apple DOS 3.3 16-sector disks, then to Apple CP/M 140K disks,
    then to Apple CP/M 640K disks. Then they got transferred (through a
    1200 bps serial cable and Kermit) to PC 5.25" 360K disks, then to PC
    5.25" 1.2 MB disks, then to PC 3.5" 1.44 MB disks. And now I have
    them on an archive CD. Well, that sums up to 7 times I've moved these
    data to newer media.

    I didn't treat all my old Apple II floppies this carefully of course,
    but only the parts I considered most important to me. A lot of Apple
    II disks in the category of "amusement" and "games" and "Apple II
    programming" remained on Apple II floppies only until the spring of
    2000, when I revived my old Apple II, got ADT working on it
    (including modifying the Apple II part of ADT such that it worked on
    my old Communications Card since I didn't have the Super Serial Card;
    no I didn't think this was "a lot fo pain" - it was fun!) and then
    transferred all my Apple II floppies to DSK images.

    because Apple is too brain-dead to maintain compatibility with older
    media formats on the new machines?

    Yelling about Apple being brain-dead won't help you. And the GCR
    format was a dead-end anyway, since the rest of the microcomputer
    industry went MFM for their floppies -- and media compatibility
    between different kinds of systems are a Good Thing. That's why
    Apple had to give up GCR disks.

    To me that's just an argument for buying a used Mac as opposed
    to a new one.

    OTOH it's a lot of pain to have to maintain a lot of old hardware
    just because you don't want to move your old files on to newer
    media. No, one old Mac is of course not "a lot of old hardware",
    but if you us ethis logic for another few decades, you will
    probably end up with numerous pieces of old hardware.


    Given time, Apple will probably eliminate floppies entirely.

    Not only Apple will do this -- the entire computer industry is
    moving in this direction. Dell has just started to deliver new
    PC's without a built-in floppy as standard equipment - yes you
    can still get it, but then you'll have to tell them you want it.
    In another 5 years or so, I think it will be hard to find a new
    computer with a floppy drive, either built-in or as extra equipment.

    And 5.25" floppy readers are ALREADY hard to find, in particular
    the older 40-track readers are next to impossible to find.

    So then should I transfer all my old files to Zip disk?

    Nope! Zip disks are probably on their way out too. And most
    computers don't have Zip disk readers anyway....

    Or CDROM?

    Yep -- that medium is very widespread and will probably be easily
    accessible for at least another decade or so. CDROM-only readers
    are on their way out, but all DVD readers can read CDROM disks as
    well.

    Or floptical? Or magneto-optical? Perhaps QIC-80 tape?

    ....please try to be reasonable... :-)

    BTW you forgot to mention memory sticks.... :-)))))

    Your argument asks the user community to spend a lot of time and money
    based on a guess as to which products are going to survive, when even
    the folks at Apple don't always have a clue (e.g. Apple III, Apple Lisa, Apple IIc+, etc.)

    Why should they? A lot of them probably weren't even born when these
    computers had their heydays.... :-)

    Failure to *offer* minimal backward compatibility is the stupidity
    of Apple, not that of people who have a lot of media.

    Should today's computers also maintain backwards compatibility with
    8" floppy disks? 9-track tapes? 7-track tapes? Punched cards?
    Punched paper tapes? (I've dealt with all these old media myself,
    earlier). Think of the people who have such old media -- isn't it
    stupid of the computer industry to offer minimal backward compatibility
    to these?

    There are a lot of obsolete media. And if you want to continue having
    access to your old data, you have two choices:

    1. Move the data on to newer media

    2. Maintain obsolete equipment to read these obsolete media.

    Maintaining some degree of backward compatibility (or at least a
    provision for adding it) is reasonable enough, don't you think?

    No question, it's reasonable. But by the same token, is it reasonable to
    expect to remain backward-compatible with everything that's ever been
    done, however good, bad, or indifferent it might be? Especially when
    doing so will effectively "hold you back" from improvements that could
    have been added, if it weren't for the fact that you can't fit 'em
    inbecause you've got 429 flavors of legacy drivers already shoehorned
    into the code?

    Perhaps Apple should think about improving the operating system so that
    basic driver support doesn't have to be "shoehorned" into the code.

    In the case of GCR vs MFM floppies, it's not merely a matter of
    maintaining old drivers, but also of maintaining old hardware. The
    latter will be expensive: Apple would have to construct their special
    floppy driver hardware, instead of just buying a standard floppy
    controller. That will make the new computer more expensive.

    Now, if you were buying a new computer, would you accept that it was,
    say, $50 more expensive just because it supported some old media
    format which you never would use and perhaps didn't even know existed?
    I don't think so.... :-)

    IMHO the problem is not the inherent stupidity in eliminating the
    floppy drive, but in offering a 3.5" USB drive that doesn't support
    the same media as the drive it supposedly replaces.

    Most likely, there has never ever been any chipset for a 3.5" USB
    drive which supports GCR. Sure, one could design, construct and
    manufacture such chips, but since few would buy them, they would
    probably become very expensive. So then the question becomes:
    how much would you be willing to pay for a GCR capable 3.5" USB
    floppy drive?

    Media do have limited lifetimes -- after some time they get obsolete
    and readers/writers for these media will no longer be manufactured.
    This happened to the phonograph rolls, the 78 rpm records, the
    reel-to-reel magnetic tame (and its predecessor: the steel wire
    intended for audio recprdings) and the vinyl record. Among computer
    media it has happened to the punched paper tapes, the punched card,
    various formats of 5/7/9-track magnetic tapes, the 8" floppy, the
    5.25" flopp, and the GCR variety of the 3.5" floppy. Within some
    years it'll happen to the other kinds of 3.5" floppies as well.

    Which ones of all these old media formats should be supported, do you
    think? Only the ones YOU possess? Or should there be some other
    deciding factor?

    There already is a deciding factor, of course: the market. Which
    means that if you're capable of activating a large enough number of
    your fellows and all of you tell apple "WE WANT THE GCR FLOPPY DRIVER
    BACK!!!", then they will start to manufacture it! That is, if you
    can convince Apple you're willing to buy them at a price such that
    Apple won't lose economically in manufacturing them. Which of course
    means the fewer you are, the more expensive it will be. And even
    you alone could probably make Apple manufacture it, if you were
    willing to pay Apple some million dollars.... :-)

    But talking about "idiocy" or "stupidity" won't help you. So
    you have three choices:

    1. Move the data to newer media. Maybe not ALL your old data, but
    those data you don't want to lose.

    2. Keep and maintain a piece of obsolete equipment for each obsolete
    media format you want to have accecss to.

    3. Lose your old data.

    Actually, they *are* still enormous in terms of the space required to
    store the data,

    True -- but replacing half-a-dozen 9-track tapes (or hundreds of
    5-track tapes) with one CD disk means an enormous saving in the
    amount of physical spaces needed for the storage.

    the labor involved in handling that many tapes to make copies,
    and the effort required to destroy or dispose of old (probably
    classified) media.

    NASA data doesn't appear to be particularly classified. NASA even
    offers raw data from these older spaceprobes for sale to anyone who
    wants to buy it !!!!! You can for instance buy a set of 30 or so
    CD-ROM's containing all the raw images from the two Voyager
    spacecrafts.

    The labor involved is what makes it an enormous amount of work.

    :-) ...that labor is a quite SMALL amount of work compared to the
    labor of constructing those space probes, sending them out into
    space, and tracking them while out in space and collecting the data.
    Plus doing science on that data. Consider for instance the two
    Voyager space probes: it took hundreds (if not thousands) of men
    YEARS of work to carry out the Voyager project. Now, how long
    would it take to copy perhaps a few hundred magnetic tapes onto
    30 CD-ROM's ? My guess is that 2 or 3 people would do it in
    a week or so. Now, which labor is most "enormous"?

    It would be just plain stupid of NASA to carry out large space
    projects if they also weren't willing to preserve the data from
    these projects, including moving it into newer media whenever
    necessary to guarantee that the data isn't lost.

    You're missing my point--the value of the data isn't at issue.

    If the value of the data is uninteresting, why bother storing the data
    at all?

    Its that the cost of the *labor* to load all the old data and copy
    it to new media is going to *far* exceed any savings from reducing
    the amount of physical space occupied by the 9 track tapes.

    So you claim -- did you throw any figures on this backing up your claim?
    These figures should include estimates of the cost of the data transfer,
    and the cost of the additional storage needed to store 9-track magnetic
    tapes vs the equivalent amount of data on CD-ROM's or DVD's.


    The mean lifespan of a CDROM or DVD isn't significantly different than
    that of 9 track tape.

    I don't know about that. Try to leave a CD and a 9-track tape
    outside for several months, no matter what the weather's like
    (strong sunshine, heavy rain, perhaps even snow). Which one of
    the two do you think will be most easily readable after such a
    treatment?

    But physical lifetime isn't at issue here really. It's rather the
    "logical lifetime" which is at issue: how long will readers for the
    medium continue to be available? And if it gets unavailable at
    some point, how much does it cost to maintain your own obsolete
    reader in order to be able to read your obsolete media?

    Finally, you're missing the most important point when you say:

    # You're missing my point--the value of the data isn't at issue.

    The reason we bother to store these media at all is the value of the
    data, isn't it? To ensure against data loss due to slow spontaneous self-destruction of our media, the data must be copied onto new media regularly. If the most cost effective new media turned out to be
    9-track tapes, then the data should be copied from the old 9-track
    tapes to the new 9-track tapes at least once every 20 years or so.
    Which means we won't save the labor cost of copying onto new media
    anyway....


    By your argument I should copy my 3.5" DSDD floppies to 3.5" DSHD

    You don't need to do that each and every time a new format is released

    Its hardly "painful" to buy a Powermac for ~$15 and have it available
    so I can transfer files from my Apple II to my PC, or out onto the web.

    As long as it works it's OK. But what if it stops working? How do you
    intend to repair it then?

    My own old Apple II is getting flakier and flakier. My only remaining
    40-track disk drive no longer works, so now I only have 80-track disk
    drives working - which means I cannot write 40-track disks such that
    they are easily readable by other 40-track drives. But getting that
    Apple II to start at all gets harder, and usually invilves removing
    and re-inserting several expansion cards, cables, and sometimes some
    chips as well. However, it won't matter that much if it fails
    permanently some day, because now I've transferred everything I
    possibly could want to use into newer media, either as .DSK images
    or as individual files.

    So then should I transfer all my old files to Zip disk? Or CDROM?

    Yep -- that medium is very widespread and will probably be easily
    accessible for at least another decade or so. CDROM-only readers
    are on their way out, but all DVD readers can read CDROM disks as
    well.

    I agree with much of what you said in concept, but there's still a
    question of degree. An average user can't make a reliable guess
    as to which media formats are likely to survive versus which are
    going to be left behind almost immediately.

    Predicting the future is of course hard, but even the average user
    can remain alert and notice when a particular medium he uses seems
    to fall out of use. When that happens, it's time to copy the data
    you don't want to lose onto newer media.

    My wife wrote a PhD thesis in 1983-1985, using a MicroBee computer as
    a word processor, bought specifically for that purpose. Floppy
    drives were then still quite expensive, so she stored the text on
    cassette tapes (!). But soon she borrowed someone else's MicroBee
    and transferred the tape contents to MicroBee CP/M disks. These
    disks were MFM disks, but were a bit special - they could store 400K
    on 40-track double sided disks while e.g. the IBM PC only stored 360K
    on such disks. Anyway, some years later I found a PC utility which
    was able to read (and also write and format) some 400 different CP/M
    formats (Apple II CP/M was not among these of course, since GCR disks
    cannot be read on the PC), and using that I transferred her files to
    PC disks. Since then they've made it to an archive CD.

    My view is that Apple goofed in failing to offer media compatibility
    to the previous generation of computers, that is, the standard 3.5"
    drive. I don't expect them to offer backward compatibility to
    previous generations (e.g. 8" disks, Hollerith cards, etc.).

    Didn't Apple have a few generations of Macintoshes where the 3.5"
    floppy could handle both GCR and MFM disks? If you're an owner of
    such a system, why not convert your GCR disks to MFM disks?

    You say "Apple goofed" --- well, that's open to interpretation. They
    certainly made you disappointed. However, Apple would probably have
    lost money if they continued to provide GCR support to those very few
    who still wanted it --- and that would probably be considered a
    "goof" by other people who aren't interested in GCR disks.

    Now, if you were buying a new computer, would you accept that it was,
    say, $50 more expensive just because it supported some old media
    format which you never would use and perhaps didn't even know existed?
    I don't think so.... :-)

    If I were buying a new computer, I would pay $50 for the ability to
    read all of my old software, documents, etc. on it.

    Sure, but would you want to pay for the ability to read old software/etc
    you don't have and aren't interested in?

    It could be offered as an option, such as a USB 3.5" drive so that
    people who don't want to pay the $50 don't have to.

    So then we would have a MFM-only USB 3.5" drive for some price, and a MFM+GCR-capable USB 3.5" drive for $50 more. Guess which one would
    sell best? I believe the MFM+GCR drive would sell so bad that Apple
    would be forced to raise its price to perhaps $500 or more, or else
    they'd lose money on it. And then NOBODY would buy it....

    The 3.5" drive is a standard format used for ~15 years
    on 90%+ of the computers out there.

    The drive itself isn't the problem - any 3.5" _drive_ can be used
    for either MFM or GCR. The drive is merely the "tape recorder".

    The problem is the disk controller chip, and the fact that GCR is NOT
    a standard low-level disk format. GCR was invented for the Apple II
    in order to NOT have to buy one of those very expensive disk
    controllers available back then, but instead be able to do the
    low-level bit shufflings using some simple logic chips plus a state
    machine ROM.

    But talking about "idiocy" or "stupidity" won't help you. So
    you have three choices:

    I don't expect "talking" about it to accomplish anything at all.
    Rather, I voted with my feet and bought myself a PC, and another
    PC, and another PC, etc.

    As a matter of fact, I did too .... never liked that a GUI was forced
    upon you on the Lisa and Macintosh. Now GUI's are ubiqutous of course
    and I've gotten used to them, but I still want the option of a command
    line when I want one. Interestingly, Mac OS X seems to have revived
    the command line, or at least its presence for anyone who wants it,
    on Apple computers.

    1. Move the data to newer media. Maybe not ALL your old data, but
    those data you don't want to lose.

    Done that; I moved my 3.5" floppies to CD.

    2. Keep and maintain a piece of obsolete equipment for each obsolete
    media format you want to have accecss to.

    Done that; I bought an Apple IIgs with 3.5" drives and 5.25" drives.

    Well, you don't need to do both of these to preserve your old data.. :-)

    3. Lose your old data.

    Done that; I dumped the stuff I didn't feel like investing the time and effort to preserve.

    I agree with much of what you said in concept, it is more a matter of
    degree. The mean lifespan of a 5.25" or 3.5" floppy disk is probably
    about 10 years.

    If stored carefully, the lifespan definitely exceeds 10 years. My
    original Appe II disks, 23 years old, are still readable. However, not
    all floppies are stored carefully....

    When they start to degrade its time to transfer them to new media.

    Then it's probably a bit too late: you won't note the degradation
    until you start to lose some data (unless you run some special
    utility which examines the tracks VERY carefully -- but who does that
    on all their old disks?)

    However, when the new machines don't offer the ability
    to read the old media, then the user is out-of-luck.

    Yep! Therefore the user should not get rid of his old machine until
    he's transferred the old data he wants to keep to some modern format.

    Of course. Thus the "value of the data" is related to the potential
    future usefulness of the data rather than the past costs of gathering
    the data.

    The cost analysis is the same whether it cost millions of dollars to
    gather the data, or whether its just a list of family recipes. It
    affects the decision of whether to preserve the information, but
    does not go to whether the format should be converted.

    Of course not. The decision whether the format should be converted
    or not depends on whether the current format has become, or is likely
    to soon become, obsolete. If there's no risk of obsolesence, then
    it'll be fine to just copy the data onto new media of the same format
    whenever the old medium starts to age too much.

    Its that the cost of the *labor* to load all the old data and copy

    Correct, but I never made any claims about which alternative was the
    most expensive. You made such a claim -- please back it up with
    figures if you maintain your claims.

    I don't think it's that important either which one of the two
    alternatives are cheapest. Any public library will face a similar
    problem: suppose it turns out to be cheaper in the long run to
    microfilm all books and then throw away the books. The amount of
    storage needed will certainly decrease dramatically. Whether it
    would be cheaper to microfilm everything is of course open to
    question. But suppose it would be cheaper for the libraries to
    microfilm everything they had. Suppose, for instance, that they
    could cut their costs into half over a 10-year span by doing so.
    Would that imply microfliming everything would be the best choice?
    No -- that decision should be based on factors other than just
    minimizing the cost.

    The mean lifespan of a CDROM or DVD isn't significantly different than
    that of 9 track tape.

    I don't know about that. Try to leave a CD and a 9-track tape

If you're buying a cheap older Mac for purposes of moving data between your Apple IIs and the rest of the world, you might be better off buying a Quadra or other 68K Mac instead. (I haven't personally verified this problem with my beige G3 because Mac OS

    ~$50/hr to transfer media at approximately one hour labor per 9-track tape
    ~$128/mo for a 10 x 10 warehouse space with climate control

    Example:
    100,000 tapes stored in a 10 x 10 climate controlled warehouse

    Cost to transfer media, not including cost of new media:
    = 100,000 * $50/hr * 1 hr/tape = $5,000,000

    Cost to store 9 track tapes for a decade:
    = $128/month * 12 months/yr * 10 yr = $15,360

    These figures are based on advertised cost of a 10 x 10 public storage
    locker at www.publicstorage.com. I expect that GSA could cut a

    This shouldn't have been an issue with creating disks for your 386, but if
    you were moving data on 5.25" DD floppies between an XT (with a DD drive)
    and something newer (with a HD drive), you ran into a problem with the head width of the high-density drive being half that of the double-density drive. Formatting/writing to a DD disk in a HD drive was an iffy proposition if you need to read the disk in a DD drive...maybe it'd work, or maybe it wouldn't.

    (When I needed to make a boot floppy for my PC/XT so I could load DR DOS
    onto it, I yanked its floppy drive out and hooked it up to whatever I was running at the time (probably a K6-2 or K6-III box) to write some disks. Nowadays, I can just plug it into the network and pull files off of anything that speaks SMB: the Windows boxen, the Linux server, or maybe even the G3. (There's some amount of SMB support in Mac OS X.))

    The best way to do this is to _erase_ the DD floppy before formatting
    and writing it on the HD drive. This ensures that there is no interfering information in the portion of the track not written by the HD drive (that
    the DD drive will read).

    A demagnetizing coil is best, but, in a pinch, a powerful permanent
    magnetic field can also be used effectively.

    The ubiquity of pre-formatted disks makes just using a "virgin"
    disk a non-option.

    With a scanner with an ADF, I'd think that you could automate most of the
    process of reading in punched cards. It won't be as fast as a card
    reader,
    but it'd be faster than anything that would involve manual intervention.
    (Maybe it'd even do a better job with lace cards than a card reader. :-) )

    I think you're underestimating the whole "hanging chads" incident...

    I don't think so.

    First, hanging chads are made by people, not by properly operating
    machines. In over ten years of working with punched cards, I can't
    remember a single incident of data error caused by a partially
    punched hole.

    Second, most card readers work by either electrical sensing (making
    a contact through the hole) or photo sensing (shining a light through
    the hole). All readers pass the card through a "throat" which is
    narrow enough to admit only one card. If a partially punched chad
    swung away from the hole, it would be "stripped" by this throat,
    and if it swung toward the hole, it would be folded into it and
    appear to be a non-punched hole. In the latter case, of course,
    data error would result.

    Examination of the throat areas of fast card readers never turned
    up any chads that had been stripped in the reading process, so
    this confirms that partial punching must be extremely rare.

    In dealing with tens of thousands of punched cards that were
    punched on keypunches, I never found a non-systematic error
    caused by the punch. (There was a case of a plugged punch
    die hole, so that all punches in that row were missing, but
    such an error is pretty evident both in physical examination
    and in reading the mis-punched data).

    In the particular case being discussed, we are probably dealing
    with cards that have already been correctly read, and were
    stored, and now need to be re-read for archiving. In this case
    I would expect that photo-scanning would be quite accurate
    in capturing the data. If anything, I would be more worried
    about mis-feeds and double-picks by the document feeder.
