OS 7.5.3 on CD for reinstall?

with a 60LC040 processor the max system you can install on it is Mac OS 8.1

System 7.5.3 and update 7.5.5 are available to download.

You will need a uitility that manages disk images on your PC in order to convert them into floppies.

Do not attempt to process the download files on the Windows machine. You must download them and transfer them to removable media without opening the files. If you put the files on a CD, make sure that you use a recording format that is compatible with Apple machines. The recommended format is ISSO 9660. This may not be the default format for your Windows CD Burner.

Upgrading above OS 7.5.5 to OS 8.1 or 8.0 will require alot more hard disc space than you might have. OS 7 uses about 16MB, OS 8 uses over 100MB.

Xou will need Stuffit on the Performa-and PC Exchange to use PC-Disks. To get Stuffit use this (Jan Hedlund,quoted):
"Go to this web page ( http://rrzs42.uni-regensburg.de/Macintosh/files/macftp.html
). Download the MACDISK.EXE file onto your PC. Prepare an empty 1.44 MB PC-formatted diskette via the FORMAT A: command in DOS or the "Full" formatting option under Windows (this is an important step). Run the MACDISK.EXE program on the PC (you may have to temporarily unload any anti-virus software to do this). Follow the instructions on screen. When ready, immediately eject the floppy (now automatically in a Mac format, ready for use in a Macintosh computer) and move it to the Classic. Drag-copy the StuffIt Expander installer onto the hard disk. Run the installation program."

Yes, the best way would be to reformat the hard disk, and then install a fresh operating system (and other programs). However, you would need either a bootable CD or a suitable startup floppy (typically, a Disk Tools disk).

At this point you could do this instead:

a) Place all decoded System 7.5.3 files (one .smi and eighteen .part) in a common folder (New Folder from the File menu).

b) Download the Disk First Aid 7.2.2 .bin file ( here) on the PC, transfer it to the Mac and decode/decompress it. Launch Disk First Aid. Select the hard disk and click Verify. If everything is OK, carry on with c) below. If DFA reports an error, post back.

c) Double-click on the first 7.5.3 file (the .smi). This will mount the total disk image. You will find the installer in the mounted image. Open the installer.

d) Proceed according to Step 7 in KB article # 60717. BTW, the Command key is the one with an Apple.

e) Proceed to Step 8 (but you do not have to update to 7.5.5 right now).

f) If everything is working OK after a restart, you can throw the Previous System Folder and other not wanted files and folders into the Wastebasket (Trash). Empty the Trash from the Special menu.

You should try to create a tools floppy as soon as possible. Post back for more about this.

Hi,

The technical specifications page for the LC 580 is somewhat confusing, since it is based upon a PPC-upgraded machine. If you have the standard (non-PPC) computer, it should be possible to start from a Network Access Disk 7.5 floppy ( here). Once the .bin file has been decoded/decompressed, use Disk Copy 4.2 (the Make A Copy button) to convert the resulting disk image to a floppy. When the floppy is ready, try to boot from it. If OK, put this disk aside.

You can then make another Network Access floppy. Move all files in the three folders Apple Menu Items, Control Panels and Extensions (all in the System Folder of the floppy) to the Trash (and empty the Trash). Drag-copy the previously downloaded Disk First Aid 7.2.2 application onto the floppy.

You can make yet another Network Access floppy. Download Drive Setup 1.7.3 ( here). Decode and mount the Drive Setup .smi file. Copy the Drive Setup application to the hard disk. Now, move the System suitcase out of the System Folder of the Network Access floppy, to the main floppy level. Drag the remaining System Folder from the floppy to the Trash (and empty the Trash). The floppy should at this time contain merely a System suitcase. Then, drag-copy the Drive Setup application to the floppy. Finally, rename Drive Setup (call it Finder). This floppy will boot directly to Drive Setup (not the normal Desktop).

You would have to buy Mac OS 8.0/8.1 (the 8.1 update is free, but requires 8.0). System 7.5.3 (7.5.5) should be quite adequate in most cases, though.

iCab 2.9.8 works well with System 7.5.3/7.5.5 in a 68040-processor Mac (7.6.1 is needed for PowerPC; at least according to the download page). WannaBe is a very fast, text-based, web browser.

In the Apple Extras folder, installed by System 7.5.3, you will find a Network Software selector. In the Open Transport position, the TCP/IP control panel will be active and visible (MacTCP inactive and hidden).

Please note that more RAM is needed with Mac OS 8.0 or 8.1.
