Image Files for booting you Macintosh

Most of these are drive image files that must be raw-written (bit by bit) on to the target media, you cannot simply copy the files on to the target media (FloppyEmu is the exception).

These image files contain the minimal system files required to boot, once you’ve downloaded one of my images, you can upgrade to the full version of the system files by downloading what you need from the internet archive.

  • The System 6.0.8 images are for older 68k systems that may only have 1MB of memory installed.  The SE/30, Classic, Classic II, Portable, II, IIx, IIcx, IIci, IIsi, LC typically shipped with only 1 MB of memory.  I’ve managed to track down a scan of the Apple Memory Guide from November 2000 (pdf) that shows how to upgrade the memory for these and other 68k systems.
  • The System 7.5.0/OS 7.5.5 images are for the remaining 68k systems that have 2MB or more memory installed.

Additionally all images files, except the floppy files, contain numerous utilities to help you get started (see included files below).

  1. Size: Because manufacturing issues, the number of MB/GB your device says it can hold might not be the actual amount.   It could be a bit more, or a bit less.  I have two SD 4GB cards, one that has a capacity of 4,024,434,688 bytes, and another that has a capacity of 3,965,186,048 bytes. These images were purposely created to be smaller than the maximum stated capacity of the storage media to compensate for bad sectors and variations in storage capacity.
  2. Sector Count: Used in section 3 when configuring the size of your SCSI2SD drive(s).  The default sector size in SCSI SD is 512 bytes, the sector count is the size of the image file in bytes divided by the sector size.   If the sector size is NOT 512 bytes you’ll need to calculate this value for yourself.
  3. Block Count: Used with DD: BS=1M count=## for extracting the first portion of your SD card to an image file to edit/update.
  4. SCSI2SD: I haven’t created any image files larger than 2GB, I’m assuming if you have a drive larger than 2GB, you are using SCSI2SD, and you plan to setup your SD card as multiple virtual drives.

Included files

  • The minimal system files for both System 6.0.8 and System 7.5.5.  You can select which version you want to use using System Picker. You can upgrade to the full version using files from the internet archive.
  • Utilities for for getting setup:
    • System Picker by Kevin Aitken that allows you to select which System Folder is active (blessed) on restart (so you can boot with 7.5.5 then switch to 6.0.8 to reduce the memory overhead)
    • SCSIProbe 4.3 by Robert Polic will tell you the device type, vendor, product and version for any device connected to your SCSI bus.
    • TattleTech 2.59 and 2.17 by Decision Maker’s Software, Inc that provides detailed information on your system’s configuration.
    • A patched version of HD SC Setup 7.3.5 for formatting your SCSI drive, device or equivalent once you’ve booted your Macintosh (patched to support non-Apple SCSI Drives)
    • Lido 7.56 by Surfcity Software, an alternative utility for initializing and formatting drives.
    • Disk First Aid 7.2.2 by Apple a tool to verify and repair issues with your hard drive
    • ResEdit 2.1.3 lets you change creator/type codes
  • Utilities for installing Applications:
    • Disinfectant 3.7.1 by John Norstad a virus scan software for checking files you’ve been downloading off the web.  All files on this drive image have been scanned.
    • Disk Copy 4.2 by Steve Christensen (for Apple) for creating image files from floppy disks, or writing images back to floppy disks
    • DropDisk by Mike Wiese and Chris Cotton that allows you to quickly mount and use disk images created with Disk Copy or ShrinkWrap (drag image on to Drop Disk’s icon)
    • StuffIt 1.5.1 by Raymond Lau (the last shareware release before becoming an Aladdin product)
    • StuffIt Expander 5.5 (freeware, installed and installer) by Aladdin Systems, for opening StuffIt and other archive files (.arc, .bzip, .bin, .cpt, .dd, .gz, .hqx, .lha, .img, .lhz, .pkg, .sea, .sit, .smi, .tar,  taz, .uu, .Z, .zip)
    • MacBinary II+ 1.0.2 (freeware) by Peter Lewis, for encoding/decoding files as MacBinary (.bin)
    • ShrinkWrap Version 2.1 (last release before becoming an Aladdin product) by Chad Magendanz, for creating files that you can mount that emulate a floppy disk or hard disk.  I use this program to create 32MB ProDos image files that I can use to transport and backup the contents of my ProDos partitions I use with my Apple IIe card.
    • Adobe Acrobat Reader 3.02 for viewing PDF files (manuals)
  • Drivers and extensions (included, but not installed):
  • Utilities for creating your own disk images / guides:
  • Network and the Internet (included but not installed):

    • OpenTransport 1.3  by Apple, replaces MacTCP, faster, but requires more memory.
    • AppleShare Client 3.7.4.   Note: The installation of AppleShare Client 3.7.4 inhibits the use of Classic Networking in 7.5.3-7.5.5, because while ASC 3.7.4 is installed, OT 1.1.2 or later must be installed for it to be active. If you wish to use MacTCP in 7.5.3+, then do not install AS 3.7.4..
    • Internet Config 2.0.2 used by some applications to centrally manage your internet configuration so you don’t need to re-enter information multiple times
    • LaserWriter 8.5.1 updater, adds support for IP printing and installs the CFM-68k Runtime Enabler 4.0 required by Netscape Navigator 4.0 and some other software.
    • Fetch 2.1.2 by Dartmouth College a very simple FTP client.  I use this and my Asanté EN/SC to move files to and from my Windows PC. Note you can buy Fetch 4.0.3 for use on System 7.
