Mac Classic, System 7,0 (or 6.0.7), secure delete ...

A friend is retiring her venerable Mac Classic running System 6.0.7 (and MacWrite II) in favour of a grape iMac she's getting free from another friend (oh my, what a shock she'll have - from System 6 to OS 9 in one fell swoop!). Anyway ...
Moving the data over isn't a huge problem, I think she's opted for 1.44MB floppies and an external floppy drive for the iMac. It's the data left on the Classic that's worrying her.
I'm sending her my complete set of System 7 Install discs from my original Classic, which includes the Disk Tools disk, on which is the System Folder and HD SC Setup (version B1-7.0)
So, the question is (aah, finally, you're thinking!) ... Does the version of HD SC Setup as supplied on the System 7 discs for the Classic (they install System 7.0, although there is a "System 7 Tune-Up" disk too) and especially the Disk Tools disk have a secure delete option? Unfortunately the Classic in question is over 250 miles away so I can't get to it at the moment.
Will I need an third party utility to completely erase the data on the internal hard disk or will HD SC Setup do it?

Burn.sit is only 89 k-should work.
You can use a 7.5 DisTools Disk on the Classic. For DiskTools you may look at

  • How can I transfer document files from my mac classic to my macbook?

    I have a floppy drive on my old mac classic and cd drive on my macbook.  Is there some way to connect the two and transfer files directly?

    A Macintosh Classic (http://support.apple.com/kb/sp198) has a SCSI hard drive. Even though the hard drive can be removed and placed in an external SCSI enclosure, it is not going to be easy to find a way of connecting it to a modern Mac. That would normally require a USB-to-SCSI adapter, which may or may not be supported under the latest operating system versions.
    The easiest method of transferring files from a Macintosh Classic may be via an external USB floppy drive connected to the modern Mac. 1.44 MB Mac-formatted floppy disks can be used for such transfers (not 800K).
    A SCSI Zip (100) drive could in principle be connected to the SCSI port of the Macintosh Classic. The Zip disk could then be moved to a USB Zip (100) drive connected to a modern computer.
    The Macintosh Classic does not have built-in Ethernet, nor a slot for an Ethernet card (certain other "classic" Macintosh computers do have the ability to hold an Ethernet card). There are some external solutions (such as SCSI-to-Ethernet adapters), but with limitations. For a networking overview, the http://www.applefool.com/se30/ web page could perhaps be of interest.
    It is also possible to arrange a null-modem connection between a Macintosh Classic and a modern computer, providing that a USB-to-serial adapter is attached to the latter (appropriate terminal emulation programs are needed on both sides).

  • Hard time for selecting Startup Disk (partition) in Mac Classic II.

    Dear coleagues, I'd like your help to understand and solve a tricky trouble. I'm sorry for the long text, but the issue is probably living in a small detail.
    The issue regards a Mac Classic II with internal and external HDDs. Internal HDD has two partitions, a smaller with System 7.1 (first) and a larger with System 7.5.3 (second). This one is installed there since 5 years ago, working fine.
    The (just installed) external HDD has 6 partitions (because of its size 9 Gb). It has been formated runing VCP in this Classic II itself and all partitions are initialized with HFS. It is intended to be a backup for my Classic II as well as my Mac Plus. I've started Installing System 7.5.3 in its third partition. Other partitions remain still empty.
    Using only internal HDD I can already perceive that "Startup Disk" control panel is unable to change the boot partition attribute between partitions in the same drive. When I open "Startup Disk" it usualy both partitions of internal HDD are highlighted. I can select a Zip Drive, for instance, and it will boot from Zip. But, when I switch it back to HDD, doesn't bother wich partition I select, it will always boot with the same partition (usually 7.5.3). Then, If i open Startup Disk CP again, both partitions are again highlighted.
    To switch between partitions in the same drive, I use Lido 7.5.6 PMount and there I select the boot partition. Then every time I select my HDD, that'll be the default boot partition.
    My conclusion is that in Mac Classic II the Startup Disk CP is unable to set a partition within a drive, it selects the drive only. The boot will obey the drive's partition table flag. That's why I can do it whith Lido, writing directly at HDD's flags.
    Now, attaching the external HDD, I can see all its partitions in Startup Disk CP and then I select one of them (the 3rd, with 7.5.3). Before rebooting, I close and open again the Startup Disk CP, then I can see all its 6 partitions highlighted. Just like I've been doing with the internal HDD, probably the solution to set a specific boot partition would be through Lido 7.5.6 PMount again. But Lido is unable to handle this drive. It appears gray in the drives list.
    What does it sound to you? What would you recommend to test? Is there an alternative for Startup Disk CP?
    Thank you.
    Regards, Ciro (Brazil)

    Dear Jan, good Evening.
    Thank you for your time.
    In fact I can select a specific partition, but by closing and reopenning Startup Disk CP I realize that the selection has been attributed to the physical drive (all partitions highlighted).
    I have tried Startup Disk CP in both System 7.1 and System 7.5.3. They do the same way.
    Internal HDD has been formated, partitioned and initialized with Apple HD CS Setup.
    This external HDD in a different way. Apple HD SC Setup hasn't been able to "see" it, probably because of its prior format system. Lido neither. That's why I went to VCP. Moreover, as it is too big for 68030, I had to format it attached to a Performa 6360. After formating, I've let VCP make set the partitions in HFS mode (partitions with 512, 1024 and 2032 Mb).
    I've mounted VCP in Mini VMac to get some screenshots for you:
    Bringing it back to Mac Classic II, it could be mounted with Lido, but System 7 has asked to initialize all partitions again. I've accepted, installed system 7 on it, and it didn't boot. Then I've repeated the partitioning and initializing procedures using Apple HD SC Setup (since now there's a Mac HDD with "small" logical drives). Nothing changed.
    I'm following your tip about System Picker. I've downloaded the sit file and read about it. It seems to be able to overlay the problem. I'm gonna try it and report back here.
    But I feel still uncomfortable not to be able to do things the regular way. As far as I know, the boot partition is an attribute of a drive partition in partition map, just like the "Active Partition" found in FAT systems. I should be able to write there as I can do with Lido in internal HDD.
    Thank you, Jan.
    Best regards,
    Ciro Bruno.

  • 10.4.7 Update and Classic System Folder

    I installed 10.4.7 with no problems.
    However, I needed to start Classic to run an old application, and when it started up, I got a message stating that changes were required. I allowed the changes to be made and the old application started up with no problems.
    Today I tried to boot up my QuickSilver using the Classic partition. (I've done this routinely for the last two years to do repair work on my 9.2.2 partition.) The machine would not boot. Instead it booted using my regular 9.2.2 System folder.
    When I checked the start-up folders using the OS 9.2 Startup panel, it showed the Classic system as version 9.2.5. (Using the 10.4.7 Startup pane, there is no version given at all, it just states "Mac OS.") The system file was updated during the changes to Classic. The QuickSilver will no longer boot from this partition.
    I would still like to boot from the Classic partition. Is there a workaround for this?
    QuickSilver   Mac OS X (10.4.6)  
    QuickSilver   Mac OS X (10.4.6)  

    Apparently during the "update" of the Classic System folder, there was a glitch. I replaced the Classic System File using the one from my OS 9.2.2 System folder, and I can now boot from the Classic partition AND Classic runs fine from OS 10.4.7.

  • Trying to install the classic system folder

    Hi All, I have 10.4.11 installed on my G4 Cube and would like to use OS9 applications. I understand that I have to use the Classic environment and I have followed the apple instructions to restart the MAC with the OS9 disk and install.

  • IMac .docs to Mac Classic

    I own a powerhouse 27" iMac, but I love the old Apple/Macintosh Computer systems. I collect them and even do a minor bit of written work on some of them... just for the nostalgic feel of it.
    My question is this: How do I get an RTF file written in Word, Text Edit or [preferably] Pages to transfer over [and be readable/workable] on the Mac Classic?
    It works via 1.44mb floppy the other way around, but I can't get anything written on the iMac to be legible on the Mac Classic.

    iconRED,
    Part of what you are seeing is meta data. The best illustration of meta data comes by opening a Word '97 document with Word 5.1. The older software will show a lot of gibberish, including information like who created the file and where it is saved to on the hard drive. But, on page ten or twelve, you will see the clean text from the newer software.
    Newer software has added so much more information that the older software does not know how to deal with it. The trick is to get the newer software to save the files in the simplest of file formats. Easier said than done.
    For example, Office 2004 will crash OS X if you copy more than just text from a website and paste it into a Word document. Copy a file from a website and paste it into TextEdit, paste it into Pages and paste it into Word. You will get three different results. If you copy just small blocks of text from a website, you should get more predictable results.
    For example, look at this page:
    http://apps.leg.wa.gov/RCW/default.aspx?cite=1.04
    That page gives you three options for looking at the data.
    First, one cite at a time,
    Second, the whole chapter at a time,
    and
    Third, "print friendly version."
    If you copy and paste the whole page into a word processing application, you will end up with some gibberish. If you view the 'printer friendly page and copy the whole block of text, but not the whole page - do not use 'select all' under the edit menu, you will get nice useable text to paste. That information will paste nicely into Word 3.0 or 5.1. The fact that Microsoft successfully developed a way to crash OS X each and every time you try to paste anything but text into a Word 2004 document just shows how much extra junk is included in newer word processing documents.
    So, if you want text documents to open cleanly in older software, you need to strip out all the junk. In other words, create a true RTF document on a new computer using new software and you will have backwards compatibility. Add any new features like photos, tables, hypertext, HTML, etc. and you will get gibberish on your older computers.
    Hope that made sense.

  • FONTS on OSX 10.4 And Under Classic (System 9 )

    Okay - Ya' all be gentle. Remember - there are no STUPID questions. I'm running a new G5 but have lots of earlier stuff and a very large file of FONTS on my old - very old - G3 - system 9.2. Classic seems to be running fine but the fonts available in the classic environment are very limited. I thought I would just copy my fonts into the system 9 - System - Fonts folder. I'm wrong!
    When I try to open System 9 - System Folder it refuses telling me System is being used by System 10. I've tried shutting down Classic and get the same results.
    Anyway - this old dog would be most grateful if someone knows how I get my old familiar system 9.2 fonts installed in the system 9 (Classic) operating system on my shiny new G5. It seems to me that I have to have TWO system font folders - one for 10.4.3 which is fine and one for system 9.2 or Classic. Since I have YEARS of Pagemaker files archived and since Pagemaker is still system 9 based I really need a bit of help here. Thanks.
    G5   Mac OS X (10.4.3)  

    Okay - Ya' all be gentle. Remember - there are no
    STUPID questions. I'm running a new G5 but have lots
    of earlier stuff and a very large file of FONTS on my
    old - very old - G3 - system 9.2. Classic seems to
    be running fine but the fonts available in the
    classic environment are very limited. I thought I
    would just copy my fonts into the system 9 - System -
    Fonts folder. I'm wrong!
    You're right. That's precisely where you should put any fonts which you want to use with Classic.
    OS X sees fonts in seven places:
    1 System/Library/Fonts. System fonts live here. You cannot add or remove fonts from this folder.
    2 Library/Fonts. Fonts which can be accessed by all OS X users live here. Put a font there, all users (except Classic users) can use it. Apple includes several fonts in that folder. Fonts placed there can be removed at will. Fonts can be added to that folder at will. Fonts in folders will show properly.
    3 System Folder/Fonts. This is the OS 9/Classic fonts folder. Fonts can be added or deleted at will, so long as you don't delete the System fonts (Chicago, Geneva, etc.) and so long as you don't drop fonts in folders in there. Fonts in that folder are visible to Classic users, and to all OS X users. Fonts elsewhere may not be visible to Classic users, depending on which font manager you use.
    4 <user>/Library/Fonts. This is the personal fonts folder for a particular OS X user. Fonts in that folder are visible to him, only. They are not usually visible to Classic users.
    5 Network/Library/Fonts. If you have a file server, fonts placed in the network fonts folder will be visible to all users who can log onto that network.
    6 <application support folder>. Some applications, notably from Adobe and Microsoft, drop fonts in private fonts folders. They can see them, but no other applications can. Microsoft now drops 77 fonts into your <user>/Library/Fonts folder the first time you launch Office 2004 without asking permission. (Yes, this annoys me.)
    7 your font management application, if any, may use a font folder of its own. Linotype's Font Explorer X, for instance, generates a folder in your <user> folder named Font Explorer X and drops the fonts it knows about and which aren't system fonts in there. (It asks first. I like this.)
    When I try to open System 9 - System Folder it
    refuses telling me System is being used by System 10.
    Sounds like a permissions problem.
    I've tried shutting down Classic and get the same
    results.
    Classic's not the problem. You don't have permission to access that folder for some reason. Run Disk Utility, fix permissions. And make sure that when you want to change fonts, you're logged in as an admin user, not a normal user. (In the Accounts pane of System Preferences, does your user have Admin privs? If not, you're not going to be allowed to change certain settings. Period.)
    Anyway - this old dog would be most grateful if
    someone knows how I get my old familiar system 9.2
    fonts installed in the system 9 (Classic) operating
    system on my shiny new G5. It seems to me that I
    have to have TWO system font folders - one for 10.4.3
    which is fine and one for system 9.2 or Classic.
    As I said above, you have a lot more than just two font folders.
    Since I have YEARS of Pagemaker files archived and
    since Pagemaker is still system 9 based I really
    need a bit of help here.
    Pagemaker will never be updated to OS X. InDesign may be able to open some Pagemaker files. In the meantime, you need those fonts in Classic.
    Thanks.

  • Can't find classic system folder

    I recently bought a used Mac that has OS 10.4 installed on it. Everything works fine except for classic, which doesn't seem to be installed. I was told that I can simply copy the system folder of classic from another mac which already has it installed and I should be good to go. Now, I need to explain to a friend via email how he can locate this folder so he can make me a copy. Can someone tell me just where this classic system folder is located? Is it under the hard drive with the main system folder? I would love to get my classic apps going. Thanks fellas (and chicas).
    Regards,
    Billy M.

    This may work. Keep in mind that if you just drag and drop a copy of a System Folder, you also drag and copy things that may have been installed later on the host machine, such as third party extensions, etc.. that my not work on your machine. If you do this, and have issues, you can drag the System Folder to your trash and be done with it. For the best results, try to find an old OS 9 install disk. There are used ones about, eBay sometimes. The one you want is the retail version of OS 9.1. There were two free updates available to this, still posted in places you can download, to bring it up to 9.2.2, which was the last and latest Classic release version. These may still actually be available on the Apple site, if you know where to look to find them. They are necessary to make your Classic folder more compatible to run in Classic mode within OS X.

  • Mac Classic II Software Update?

    I just picked up a Macintosh Classic II that had OS 7.0.1 on it. I want to upgrade it to 7.6.1 but cannot. I can't load 7.6.1 because I need 7.6 and I can't load 7.6 because I need 7.5 and I can't load 7.5 because I need 7.1 and I can't load 7.1 because it's not available. A;so 7.1 is not for the Classic II.
    How do I get from A to Z (or 7.0.1 to 7.6.1)?
    I have downloaded a ton of older OS 7 stuff from Apple Older Software page and nothing works.

    Bud,
    Just a couple of comments.
    To get any .sea or .bin diskette to open ........ must be loaded on the MAC Classic II first.
    StuffIt Expander (for a way of obtaining the 4.0.1 version for Mac, see above) will decode MacBinary (.bin) files, as well as BinHex (.hqx). A self-extracting archive (.sea), where the resource fork has not become damaged during transit, will expand automatically when double-clicked upon. If there is a problem, one can try to drag a StuffIt .sea file (there are other .sea files that may behave differently) onto the StuffIt Expander icon. Disk Copy 4.2 is only needed in order to open Disk Copy 4.2 type disk images, and is not required for the System 7.5.3 download.
    I cannot unpack .smi yet. 7.5.3 first disk image has this and is needed to install the other 18 disk images.
    When the nineteen .bin files have been decoded by StuffIt Expander (apparently, this is what you did already on the modern Mac), they (one. smi and eighteen .part) are to be placed in one common folder on the Classic II hard disk. As indicated earlier, then merely double-click on the .smi file. This should mount the total image (the 7.5.3 installer will be found inside).
    Both the 7.5.3 (& 7.5.5) and 7.6.6 need their initial upgrade, i.e., 7.5 and 7.6 primary OS installed first.
    I think you mean 7.6.1 (not 7.6.6). In that case it is true that 7.6 is needed (nothing earlier). The downloadable System 7.5.3 however will install and work as it is, provided that the Classic II hard disk has an appropriate bootable operating system. If necessary, a 7.5 startup floppy can be made from the aforementioned Network Access Disk 7.5 download.
    A CD image can be transferred to the MAC Classic II (or whatever) by hooking up the MAC II 25 pin HD connection to another computer that that is connected to your Ethernet.
    Apple supports SCSI Disk Mode (HD Target Mode) for certain PowerBook computers (equipped with an HDI-30 SCSI port). The PowerBook would then act as an external hard drive when connected to a desktop Mac (which has a DB-25 SCSI port). Special adapter cables have to be used for this.
    Otherwise, a direct connection between two SCSI ports is not supported, and may be risky.
    It is possible to remove a SCSI hard drive from one Macintosh computer, and then (via a different kind of cabling) connect it (externally or internally ) to another SCSI Mac.

  • Mac Classic secret boot disk?

    Hello,
    Is there a secret boot disk in the ROM of Mac Classic?
    I've pressed Command-Option-X-O and got a message "Welcome to macintosh", but in English!(I have a Russian system 7).Then my mac booted up the System 6.0.1(It looks very cool!) very fast.
    I've rebooted my Mac Classic and repeated this, but it's booted System 7.1 and just shown me an icon of the diskette with a label "Boot Disk".
    I've set this diskette in the Boot Disk control panel and booted System 6.0.1 normally.
    Note:Can I Add the Russian Language or the Russian fonts to this System 6.0.1?

    Is there a secret boot disk in the ROM of Mac Classic?
    Yes.
    Can I Add the Russian Language or the Russian fonts to this System 6.0.1?
    No. It is hardcoded and cannot be changed.

  • Removing Developer Tools and Classic system from OS X

    Hello
    I'm trying to free up space on my hard drive and I was wondering how I go about uninstalling the classic (OS 9) system and Developer Tools from my hard disk? Do I just drop to trash or should I do it another way?
    Also, I was wondering if my mac mini install disks for V10.3.9 will only work on this Mac or if they could be theoretically used as install disks on another machine?

    Hi arbela:
    Developer Tools can be dragged to the trash and
    deleted. The OS 9 system generally has three folders
    associated with it: Applications (Mac OS 9),
    Documents, and System Folder. Applications (Mac OS 9)
    can be dragged to the trash and deleted, and if
    there's nothing in Documents, so can that.
    The System Folder is trickier, because of its use for
    Classic. Open the folder, then drag everything in the
    folder to the trash. Delete. Then drag the System
    Folder to the trash. You'll probably have to restart
    before you can empty the trash.
    As for your Mac Mini install disks, if they are the
    grey discs that came with the Mac Mini, then they are
    designed specifically for the Mac Mini. In other
    words, they'll only have hardware drivers for the
    components shipped with your Mac Mini. If you were to
    use the discs on an iMac, it probably wouldn't boot;
    if it did boot, and the installer ran, the iMac
    probably wouldn't boot afterwards because none of the
    drivers for the specific hardware on the iMac would
    be installed.
    Hope that's clear.

  • Mac Classic Question

    My Mac Classic won't instalise 3.5" Floppies!! And they are mint MAC Formatted disks!!

    Hi,
    This happens from time to time. The pre-formatted disks can not be read properly from the beginning. Then the verification of the new formatting is not successful. One possible cause is  that the diskettes in fact are bad.
    If you have access to another older Mac with a floppy drive, you could check whether it is possible to reformat a floppy there, and after that try again with the Macintosh Classic.
    You could even test reformatting one floppy in a PC, and then try again with the Classic. This test can also be done with a (pre-formatted) new PC floppy. The Classic should report that it is not a Macintosh disk and offer to initialise it.
    Another possibility is that the read/write heads in the floppy drive need to be cleaned (a special cleaning disk can be used for this). Can  other Mac floppies be read properly?
    It can be wise to run the computer with Extensions off (hold down the Shift key while starting up) during tests.
    The usual things like resetting the PRAM and rebuilding the Desktop should not change anything in a case like this.

    I Don't think the Apple Forum is a good place for asking question about emulate Macintoshbut i will answer this question because i like emulate my old died mac. You can use Basilisk II because it a Great Emulator and it emulate the Macintosh II (System 6 to 8.1) but i'm not sure if it will work with a Mac Classic II Rom Image. I Know it have a Mac Quadra 650 Rom image freely downloadable from the internet but i will not giving any link. You still can use anything you using with your Classic II on Basilisk II. Basilisk II Is a great emulator and it support Color (up to 32 Bit)

    I am busy archiving my collection of floppy disks using an old Mac Classic II with an attached ZIP drive. It was working fine until yesterday. Yesterday when I turned the computer on, I got the flashing question mark instead of the normal startup sequence.
    I booted off of a Disk Tools floppy and ran Drive Setup. It told me there was no hard drive to be found.
    So I'm looking for a replacement hard drive. But I seem to recall Apple doing some sort of firmware thing on the drives that could be used in their computers. Do I recall correctly or will most any SCSI disk work as a replacement?
    I'm running System 7.0.1 on this machine.

    Gary,
    Copy/Install a System folder and boot from the Zip Drive.  We used to have multiple zip disks with multiple systems.  Even OS 8.1 will fit on a zip disk if you leave out the file translation software.  For now, find a second Zip Drive and set one for ID 5 and the second for ID 6.  Hopefully you were able to back up files before the hard drive died.
    Also, a program from Mount Anything should work for you.  The point of the Apple enabled drives was that the computer would recognize them at startup and did not require special software to mount the drive.  Iomega provided Iomega Guest as a small file that could be installed on a friend's computer.  Once you used Guest to mount the drive, you could select the drive as the boot device and the Mac would boot from the Zip Drive.  Having Guest on your Disk Tools floppy would let you get up and going.
