Q: installing system 7.1 onto SE30 with 7.5

Hi I have an SE30 with System 7.5 - however I wish to install System 7.1 as it'd be faster and less memory intensive on my SE30.

Inserting the Install disk and running the install script reminds me that I cannot install System 7.1 and need to remove the (already installed) System folder - I presume this is because the System already installed is a newer version.

 

I have tried inserting the 7.1 install disk 1 and pressing C to start up from the disk - to no avail.

 

How can I install and downgrade the 7.5 to 7.1 ?

 

I just want to use the SE30 for documents and email and years and years of OS X and CD Roms and The Internet has confused me and I have forgotten much that I used to know.

 

Cheers

Macintosh SE30, Mac OS 8.6 or Earlier, SE30 with System 7.5.3

If you do not wish to erase the hard disk (reformat via HD SC Setup, or Erase from the Special menu, when starting from a System 7.1 Tools floppy), you could just manually inactivate  the existing System 7.5.x system folder. To do this, rename the System Folder to something like Old System Folder, and then drag the System suitcase out of this Old System Folder (place the System suitcase in any other folder on the hard disk). It is later possible to reverse this operation, and thus reactivate System 7.5.x (then with System 7.1 inactivated).

    If you can get access to the hard drive using the 7.1 boot diskette, or any other diskette for that matter, you could format the hard drive or delete the system folder and try installation again.  But downgrading to 7.1 will present you with more challenges if your goal is to network with the SE30... IP networking was much more of an afterthought at that time, and requires more add-on packages to get to a recognizeable state.  7.5 is hard enough at that, but 7.1 would be worse.

    Pressing the C key does work have any effect on an SE/30. The key combination that one in certain cases could use to bypass the internal hard disk would be Command(Apple) + Option(Alt) + Shift + Delete(Backspace).

     

    However, with a proper startup floppy (such as an original System 7.1 Install 1) in the floppy drive, the computer should automatically start from that disk. The floppy drive has priority over the internal hard disk at startup.

     

    I agree with JustSomeGuy that making the machine ready for IP networking is going to more complicated with an earlier system than with 7.5.x, but it can be done. Remember, MacTCP is not part of System 7.1 (it has to be installed separately).

     

    System 7.5.x installs the PC Exchange control panel, which makes floppy transfers from a PC easy (if necessary). System 7.1 has an Apple File Exchange program on the Tidbits system floppy (this program has to be installed manually) for the same purpose.

     

    Yes, System 7.1 is faster than 7.5.x on any 68030 machine.

     

    If there is a problem with your set of System 7.1 floppies (which are not provided for download by Apple), you could download System 7.0.1 instead:

     

    http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English -North_American/Macintosh/System/Older_System/System_7.0.x/

     

    The British version of System 7.0.1 is available in the form of separate floppy-sized downloads:

     

    http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English -British/Macintosh/System/System_7.0.1/

     

    Use Disk Copy 4.2 (the Make A Copy button) or 6.3.3 (the Make a Floppy command under the Utilities menu) in order to create correctly sector-copied floppies from the disk images.

    Pressing the C key at startup does not have any effect on an SE/30.

    Sorted, thanks ever so much - it's all so easy and straight forward and coming back to me thanks to you guys.

     

    What I did was rename the System Folder, remove the suitcase, start up from the installation disk and installed 7.1 then deleted 7.5 as I decided against keeping it (takes up too much space)

     

    I have invested in a USB Floppy for my current iMac Macintosh and file sharing problem solved too!

     

    Cheers!
