Install System 7 on PowerBook 145b

Hello everyone,


I have a PowerBook 145b with System 7 in German, and I would like to reinstall it in French. Unfortunately, I don't have the official installation floppy disks.


However, I have an external USB floppy drive and 3.5" floppy disks with a capacity of 1.4 Mb. Could someone tell me how to create new installation diskettes and how to install System 7 in French?


Thank you for your help.


Best regards,

Tolga

Hello Tolga,


As mentioned in my previous message, System 7.1 was the original for the PowerBook 145B and would be the first supported version.


However, an old Version Matrix, System 6.0.x to 7.0.1 from Apple appears to indicate that even the earlier System 7.0.1 may work (but not a plain System 7 = 7.0), but that should be looked upon as an experiment.

http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/French/Macintosh/System/Full_Installs/System_7.0.1/ (the link is not directly accessible any more).


The supported versions in the technical specifications for the PowerBook 145B above are:

7.1

7.5

7.1.1 (Pro)

7.5.1

7.5.3

7.5.5

7.6

7.6.1


I do not know anything about the files that you mentioned.


Normally, a system software download from Apple would have been encoded in a MacBinary format (.bin) for protection.


Generally speaking, one would use an appropriate version of StuffIt Expander (such as 4.0.1) for the decoding, but only when the .bin file has been transferred to the old Macintosh computer (which must already have a working operating system). Do not decode or decompress on a modern computer (Mac or PC). Any downloaded .bin file must be transferred unaltered to the old Macintosh.


The transfer of the .bin file from a modern computer could take place on a PC-formatted 1.44 MB floppy, provided that the receiving old Mac (such as a PowerBook 145B) has a File Exchange utility or PC Exchange. Otherwise, the transfer would have to be done on a Mac-formatted 1.44 MB floppy (plain HFS, not HFS+).


Once decoded (and possibly decompressed) via StuffIt Expander on the old Mac, the resulting files may be in an image format. In order to create bootable floppies from .image files on the old Macintosh computer, a Disk Copy 4.2 utility can be used (the Make A Copy button).

Later .img files require Disk Copy 6.3.3 (the Make a Floppy command).

There are also self-mounting image files (.smi), sometimes with several parts (.part).
