Editing my images to add the full version of System 7.5.5

In my previous blog entries I mentioned that I could not include the full version of System 7.5.5 or System 6.0.8 with my drive images due to copyright restrictions, but you could download the full versions from Apple’s FTP site…. that option is gone, and is now replaced with the files being available from the Internet Archive.   So if you are using one of the drive image files I created with minimum versions of System 6.0.8 and System 7.5.5 this guide will tell you how to update to the full version of 7.5.5.

Quick start

  1. Select the language/country for the installation files and find them on the Internet Archive
  2. Download the 7.5.5 and/or 6.0.8 installation files from the Internet Archive
  3. Setting up Basilisk II to edit my image files
  4. Install the full version of 7.5.3 then 7.5.5
  5. Write / copy the updated image files to your target media the same way you would any of my images.

1. Selecting the Language/Country

When you go to the Internet Archive you’ll see a long, long list of links to the various files that used to be available from apple.   You’ll notice there are multiple versions of both System 7 and System 6 on the site for the various languages supported by the OS, you’ll need to select which one you want to work with.   For this guide I’m going to select the English north american versions.

2. Downloading the System 7.5.5 installation files

I’m assuming you’ve already determined which version will or will not work on your Classic Macintosh or you’re just using an emulator.

For System 7.5.5 there are 20 files you’ll need to download from the Internet Archive.   The first 19 are for System 7.5.3 and the last file is to upgrade System 7.5.3 to 7.5.5

3. Setting up Basilisk II to copy the System files on to one of my drive image files

For this blog entry I’m going to use Basilisk II to edit my images, I have a separate entry listing other tools that can be used to edit my images if you don’t want to use Basilisk II. I chose Basilisk II because it can edit both my drive and partition images, and is my general “go to” emulator.

  1. Download and install and configure Basilisk II
  2. Download one of my 2GB System 7.5.5 images to use as my boot disk.
  3. Download the other images that you want to edit (or make a copy of the 2GB System 7.5.5 image if that’s what you want to edit)
  4. Create a directory on your Windows/Mac/Linux system to hold the System files you downloaded in Step 2 and the image files you downloaded from my site
  5. Run BasiliskII GUI
  6. On the volumes tab (Figure 1):
    • add the System 7.5.5 image file as the boot drive, I’m using my Drive Image: OS_755_2GB.dsk for the SCSI2SD
    • add the image(s) you want to edit
      • I’m adding my 6.0.8 Drive Image for the SCSI2SD that I’ve renamed to: OS_608_2GB_full.dsk and will update it to the full version of System 6.0.8
      • I’m adding my 7.5.5 Drive Image for the SCSI2SD that I’ve renamed to: OS_755_2GB_full.dsk and will update it to the full version of System 7.5.5
    • enable “My Computer” icon on your Mac desktop (bottom left of Figure 1), pointing to my drive D where the directory from step 3.4 above is found.
  7. Update any other settings you want to change
  8. Exit BasiliskII GUI
  9. Load Basilisk II (Figure 2)

4. Updating the System files

At this point you should have downloaded the sea.bin files from the archive (section 2 above), have Basilisk II running. For the rest of this guide I’ll be using the following names to refer to the different drives shown in Figure 2:

  • The 1st drive, 2GB 7.5.5, I will refer to as the boot drive
  • The 2nd drive, This PC, lets you access files on the system hosting Basilisk II, I’ll refer to it as the This PC drive
  • The 3rd drive, 2GB 6.0.8, is the drive I plan to update to a full version of System 6.0.8, I’ll refer to it as the 6.0.8 drive, and I’ve renamed this to 2GB 6.0.8 (full) (Figure 3 above)
  • The 4th drive, 2GB 7.5.5, is the drive I plan to update to a full version of System 7.5.5, I’ll refer to it as the 7.5.5 drive, and I’ve renamed this to 2GB 7.5.5 (full) (Figure 3 above)

4.1. Installing System 7.5.3

  1. Open the 7.5.5 drive, 2GB 7.5.5 (full) in Figure 4 above
    • delete the OS 7.5.5 (minimal) folder by dragging and dropping it on the trash, and then empty the trash (menu->special->empty trash)
    • Close the 7.5.5 drive’s window
  2. Open the boot drive (Figure 5 above)
    • create an Installation Files Folder, I called mine System 7.5.5 installation files (menu->file->new folder) (Figure 5 above)
    • Optional: Use “Wish I were” to only install the System 7.5.5 installation files for a specific 68k Macintosh vs. doing a Universal Install
      • Open the OS 7.5.5 (minimum) folder
      • Open the Control Panels folder
      • Run Wish I were
      • Select the name of the 68k system you plan you want the installation files for (Figure 6 above)
      • Restart (Special -> Restart)
  3. Open the This PC drive, and navigate to the folder containing the System 7.5.3 installation files you downloaded in Step 2.1 above (Figure 7 above)
    • Drag and drop the System 7.5.3 installation files in to the Installation Files Folder you created in step 4.1.2 above on your boot drive, this will copy the installation files on to your boot drive. (Figure 8 above)
      • If you only have the 7.5.3 installation files in the source folder, you can do a select all (menu -> edit -> select all)
    • Close the This PC windows.
  4. Select the Boot drive window, and open the Store / Mount folder (Figure 9 above)
    • Open the Stuffit Expander 4.0.2* folder (Figure 9 above)
    • Select all .bin files in your Installation Files Folder and drag and drop them on to the Stuffit Expander icon. (Figure 9 above)
    • The Installation Files Folder now contains both the .bin encoded files and the unencoded files. Scroll down in the window until you see the file System 7.5.3 01of19.smi (Figure 10 below)
    • Run System 7.5.3 01of19.smi, you should see the Apple Computer license agreement, select “Agree” (Figure 11 below)
    • You should now see an icon on your desktop called Sys 7.5 V7.5.3 CD Inst (figure 12 below)
  5. Open the Sys 7.5 V7.5.3 CD Inst drive (figure 13 below), run the installer and select continue on the “Welcome to” windows (figure 14 below)
  6. On the Install System Software Window (figure 15 below)
    • You will see a message: The Installer cannot update the version of Macintosh System Software on the disk named "2GB 7.5.5".  Please remove the System Folder on "2GB 7.5.5" and try again.
    • You are seeing that error because the current selected destination drive is your boot drive
    • You need to press the Switch Disk button until the 7.5.5 drive is selected as the destination drive, called 2GB 7.5.5 (full) for this guide (figure 16)
    • You will now see a message: Click Install to place system software version 7.5.3 on the selected disk. (figure 16)
    • Leave the drop list as Easy Install (you need to do an Easy Install first to prevent an issue with the installer), press the Install button, wait… (figure 17) press the continue button (Figure 18)
    • If you used I wish I were in step 4.1.2 above and do not want the universal install you are done and can press the Quit button…. otherwise
    • Change the drop list from Easy Install to Custom Install, press the Install button, and select the Universal System for any Macintosh, select Install (figure 19)
    • When the install has finished select Quit.
  7. The 7.5.5 drive is now updated with the full version of OS 7.5.3 (figure 20)
  8. Optional: drag the Sys 7.5 V7.5.3 CD Inst icon on to your 7.5.5 drive so you have a copy of all the installer files in case you want to make changes to your installation in the future.
  9. Drag and drop the Sys 7.5 V7.5.3 CD Inst to the trash (to “eject” the virtual disk”)

4.2. Upgrading from 7.5.3 to 7.5.5

These instructions assume you’ve just installed the full version of 7.5.3 following the instructions above.

  1. Open the boot drive (Figure 5 above)
    1. Empty the Installation Files Folder, you created in 4.1 (Figure 5)
  2. Open the This PC drive, and navigate to the folder containing the System 7.5.3 installation files you downloaded in Step 2.1 above
    • Drag and drop the System 7.5.5 installation files in to the Installation Files Folder on your boot drive, this will copy the installation files on to your boot drive.
      • If you only have the 7.5.5 installation files in the source folder, you can do a select all (menu -> edit -> select all)
    • Close the This PC windows.
  3. Open your Installation Files Folder (figure 21)
    • Run Sys_7.5.5_Update-NetInstall.sea
      • If it still ends in .bin use Stuffit Expander to unencode it (see step 4.1.4 above)
    • Open the System 7.5.5 Update Net Install folder (figure 22)
    • Run the installer
  4. On the Install System Software Window (figure 23)
    • Press the Switch Disk button until the 7.5.5 drive is selected as the destination drive, called 2GB 7.5.5 (full) for this guide
    • Press the install button, wait…
    • Press the quit button
  5. System 7.5.5 is now installed. (figure 24)

4 thoughts on “Editing my images to add the full version of System 7.5.5

  1. Hi, i need to backup the working internal SCSI of my Macintosh IIVX to an SD card via using SCSI2SD and use as an bootdisk but i don’t know how. Can some one give me step by step instructions please…?

    • Hi deniz, you should be able to:
      – config your SCSI2SD drive so drive 1 is the same size or greater than your current drive, and so it has a scsi ID of something other than your current boot disk, see step 3.1 http://www.savagetaylor.com/2018/01/05/setting-up-your-vintage-classic-68k-macintosh-using-a-scsi2sd-adapter/#comment-6031
      – connect your SCSI2SD to the external scsi port on your Macintosh IIVX
      – initialize the disk using LIDO or a patched version of HD SC Setup 7.3.5 (if you don’t have these, they are on my images, you can initialize your SCSI2SD with one of my images first, so you can copy the file off on to your old drive, then repeat these steps with the setup you want)
      – once initialized copy everything from your current drive to the SCSI2SD drive(s) (I say drives because you may have setup multiple partitions for yourself)
      – turn off your computer, disconnect your old drive.
      – config your SCSI2SD drive with the SCSI ID your old drive had
      – connect your SCSI2SD drive internally (in place of your old drive)
      – turn on your Mac.

  2. First of all your SCSI2SD articles and accompanying images are invaluable, thank you! I don’t have trouble booting your 7.5.5 images with either V6 or V5.5 SCSI2SDs in either an LC 575 or SE/30. However I’d like to update them to full versions and have been running into trouble with the SCSI2SD CD emulation scheme that’s prevented me from going that route.

    Thus, I thought this article would be just up my alley. Unfortunately, I can’t get Basilisk II on my windows machine to boot from either your 2GB or 100MB 7.5.5 images. I just immediately get a flashing question mark. All the settings are the same as what you describe (model to IIci, 32MB RAM, LCIII ROM file, only your image selected in the disk panel). It boots fine from other images, though.

    I think I’m using a much newer version of Basilisk II than you did when you wrote this article, so I wanted to check and see if these images still boot for you in the newest version and if not what old version I need to find to get this working. Thanks again!

  3. Hi Charlie, I just downloaded the 22-09-2020 release and installed it and was able to boot without any issues on my Windows 10 machine. I’m using the ROM file: ECBBC41C – Mac LCIII.ROM, Mac IIci, CPU type 68030 etc.
    Tested with both my SCSI2SD and my FloppyEMU images.

    Did you follow the instructions on https://www.emaculation.com/forum/viewtopic.php?f=6&t=5282
    1. download the original https://surfdrive.surf.nl/files/index.php/s/g3bHyqOg1326AXF/download
    2. update that copy with the latest files https://surfdrive.surf.nl/files/index.php/s/7aKvCqrAiuB5XAj/download

    Never mind, for the new 22-09-2020 version you don’t need the original version anymore and upgrade. I just read the latest information on https://www.emaculation.com/doku.php/basilisk_ii_setup. I’ll update my BasiliskII entry with the new install information
