Preferred Formats for Software Preservation

Preparing files or discs are critical to the preservation of software here on the Macintosh Repository's archive and elsewhere for that matter. This article, although not exhaustive, should provide members with the knowledge necessary to gain a foothold of the terminology, a brief background and some possible steps to prepare loose files and physical discs for upload. EXTREMELY IMPORTANT: DO NOT ZIP AND/OR DO NOT MOVE AN...

Cannot lock, unlock or delete a file under Mac OS 9?

There was a bug under Mac OS 9 (and maybe Mac OS 8 too?) that, under a special circumstance, prevented some files to be locked, unlocked or even deleted.  They would sit there in your trash forever and prevent you to empty it even when the OPTION KEY is held down.  Rebuilding the desktop does NOT resolve the issue. Trying to get file info with ResEdit results in the following error: The reason this is happening is generally...

Corrupted/blank files when expanding a ZIP under Mac OS 9 and seeing a __MACOSX folder?

If you used a Mac back in the 90's, then you remember that among Mac users, nobody ever used ZIP format for compressing files.  Everybody used SIT files instead and some used HQX, BIN or CPT files, but not a single Mac user zipped their files.  The reason is simple: ZIP files are not compatible with Mac resource forks (old Mac files before Mac OS X) and zipping an old Mac file (such as a Mac OS 9 application program) would destroy...

Getting Started (WIP)

(the [messy] WIP guide) Hi enthousiasts or nostalgics from the not too far future! Ready to undust some of the 80's, 90's or early 2000's Macintosh Software treasures and feel what it was like in those earlier computer days but you're afraid it will be too difficult or obscure to do that by yourself? Fear no more, here's a small guide that will get you started!   Step 1: Real hardware... or emulation? First...

How to "burn" (or write or clone) a bootable PowerPC disk image onto an USB stick in Mac OS X using "dd" in Terminal

This article lays out the steps in order to "burn" (or clone, or copy) a disk image (such as an ISO boot/install CD) onto an USB stick using only a vanilla Mac OS X environment that any Mac user already has available.  You do not need any additional or third party software since Mac OS X is Linux based and comes with "dd" which is all it takes to accomplish this. Read that other article if you're looking for doing...

How to "burn" (or write or clone) a bootable PowerPC disk image onto an USB stick in Windows

PowerPC Macs such as G3's and G4's can boot off of USB sticks, even if this functionality has been buried so deep in technical details that almost nobody knew about it until nobody used G3's anymore.  If you're a collector or hobbyist and got a G3 or G4 and would like to install Mac OS 8, 9 or Mac OS X on it but that the CD/DVD drive is broken, here's a complete guide that will prove to be useful to you.  It will...

How to convert .MDF/.MDS disc archives to ISO

This article focuses on what to install on your mac to allow for disc image conversion from MDF/MDS to ISO. The article covers Mac OS X 10.4 through Mac OS X 10.13.x which is the current version as of this writing. There are two candidates for solving the disc image conversion, a GUI program titled AnyToISO Converter Lite and a command line interface called mdf2iso. These two programs are not by the same author but...

How to convert a DMG file to an ISO disk image?

DMG files are disk images that are compressed using Apple's proprietary format and Mac OS X default disk image format.  The fact that the DMG disk images are compressed poses a compatibility problem to most Windows users and earlier Mac OS versions, e.g. Mac OS 9.  The ISO (a.k.a. CDR under Mac OS X) disk image format is universally supported, therefore it's a much better choice for storing files or making a disk image...

How to create a HFS+ disk image in Mac OS X to encapsulate/transfer Mac OS 9 and earlier files

Old Mac files (Mac OS 9 and earlier) need to be encapsulated properly before being moved/copied to a non-HFS partition/disk such as on a Windows PC or a web server or they will get corrupted, effectively losing their resource fork, which will render them useless on your Mac OS 9 or earlier environment. The best way to protect old Mac files before moving/copying them out of your OSX environment is to first copy them onto a HFS+ disk image,...

How to disable the airport card in the mid 2005 iBook to prevent crashing

Many iBook G4 laptops (and possibly other models) have a problem with the inbuilt AirPort card failing, and then causing regular kernel panics. This can be avoided in Leopard, and possibly Tiger, by replacing the kexts responsible for the AirPort 1. As soon as you turn the computer on quickly turn off AirPort in the menu bar. 2. Open TextEdit and save two blank files to the desktop. Name the First one  IO80211Family.kext.rtf and...

How to factory reset an old PowerPC Mac if I lost the restore CD's?

Follow this universal method that fits any PowerPC Mac model.   1) Identify what PowerPC Mac model you got. 1a) If it still can boot into classic Mac OS (8 or 9) then navigate to the Mac's hard drive, then "Applications" folder, then launch...

How to mount a disk image under Mac OS 7, 8 or 9

One of the problems retro Mac enthousiasts face nowadays is figuring out how to mount old/random disk images in order to access the game or app in it. First of all, you have to know that there were at least a dozen disk image formats back then (altough only a handful of them were widely used) and fortunately for you, there is a very nice disk image mounting tool for classic Mac called Virtual DVD-ROM/CD Utility that mounts just about all of them...

How to open most common old Mac archives on older Mac OS

This tutorial is meant for people who did not use older Macs back in the 90's who are struggling to open (or "load") old Mac files into their emulator (or even a real Mac, doesn't matter) and it's split in paragraphs that depict a specific file type/extension, so please skip to the paragraph that talks about the kind of file you're trying to open to discover how to do it.   .sit Stuffit archives Stuffit...

How to recombine (join) split ZIP files (.001, .002...) into a single ZIP archive under Windows or OSX

When you come across split ZIP files that look like sequential part numbers, before extracting files out of the archive, you first need to join the split files together into a single, complete, ZIP file.  A split ZIP file could look like this, for instance: 691-5088-A.zip_.001 691-5088-A.zip_.002 691-5088-A.zip_.003 691-5088-A.zip_.004   Under Windows Open a command prompt and navigate to the folder containing all the...

How to work with segmented files

Back in 1996, Stuffit introduced DropSegment which worked much like DropStuff (compression aoo) and StuffIt Expander (decompression app). Dropping a StuffIt archive (a single file compressed as .sit file) on DropSegment enabled the user to make a multi-segment, self-joining, self-extracting archive, which was useful for copying huge archives to floppy disks. Segmenting files has not gone away despite increases to storage,...

I downloaded something that contains .bin/.cue files, how do I mount this under Mac OS 9?

Okay, first off, there aren't a ton of .bin/.cue files, but there are some and when you'll face them, you most likely won't understand how to deal with them because it's an awkward format.  Also, you have to understand that .bin/.cue files MUST work in pairs so whenever you see them, always keep them together in the same folder and do not rename them.  The .cue file is a cue sheet that explains to the disk image...
