System 7.5.3

You must be certain NOT to unpack on a PC, but transport to a Mac and place all .part and the .smi in the same folder.

Click on the first one, and it should self-assemble and install. Did you read the directions in the info.txt file?

In particular, that you must be running 7.1 or later (possibly off a diskette)?

Snow Leopard does not maintain the metadata. You must not unpack those files there, either.

Each of the second through 19th files has a name like:
System 7.5.302of19.part.bin

This should unpack into:
System 7.5.302of19.part

If its name changes to something else, I apologize for any confusion.

Hi,

As Grant mentioned, begin by transferring the downloaded files unaltered to the hard disk on the old Macintosh computer (that is, keep the MacBinary = .bin encoding intact). For this transfer you could use 1.44 MB floppy disks or a CD.

Once on the older machine, use StuffIt Expander 4.0.1 or 5.5 for the decoding of the nineteen .bin files. StuffIt Expander 4.0.1 can be found, for example, here, but one problem is that the download has been encoded, and that StuffIt Expander is needed for the decoding...

If necessary, ask someone to help you with a ready-to-use StuffIt Expander 4.0.1 or 5.5 installer (can often be found on CDs with older Mac magazines, too).

"But I only have snow leopard, where else can I unpack the files?"

Where do you intend to use the files? That is where to unpack them.

Readers are in the dark about where you are and where that message could be coming from. Fill us in on the details of where you are now and how you got there.

According to the apple Spec here:

http://support.apple.com/kb/SP298

The minimum OS is 7.5.3, the maximum is 8.0
While you MAY be able to push that to 8.1 under certain circumstances, OS 9 is out of the question for that Mac.

This page has all the specs for 5260 on Apple's site. I believe you are right -- the ones labeled Power Mac do seem to go as high as 9.

http://support.apple.com/specs/#5260

Everymac.com says the PowerMac 5260 was sold into the Education Market, and the performa version was sold Retail worldwide.

What CD/DVD are you trying to use for this install? That error message sounds like you blundered into Mac OS X permissions issues?

NN117,

It sounds like you do not have the correct install CD.

Probably the best thing you can get for working on older macs is an external SCSI zip drive or hard drive enclosure. You can convert an external SCSI CD-ROM drive into a hard drive enclosure. Booting your computer from a CD is fine if you have the exact install CD for the machine or a universal install CD. External hard drives allow you more flexibility. Or, you can create zip disks with different system backups. It is not uncommon to get a message that says "this system will not operate this computer." If that is the case, you put in a different zip disk.

The whole point of this comment is to remind new commers that working on older computers requires 'tools of the trade.' The most powerful tool is the external SCSI drive port. If you can find a mac user group near you, you can get started with the right tools.
