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...

Building Mini vMac for Windows 10 using the Windows Subsystem for Linux

Mini vMac's site includes extensive documentation on how to build the emulator (https://www.gryphel.com/c/minivmac/build.html).  However, I found that these instructions didn't cover my use case, which was a Windows 10 machine running Ubuntu in the Windows Subsystem for Linux. My build unfortunately ended up being a bit of a hack, because the Makefile generation did not quite get the command lines for the C compiler and tools...

Can I somehow interface communicate between my iMac G3 and my Windows ME PC?

Alright so I'm sure that's a bit of a weird question but here is the situation- my PC is a Windows ME running Gateway from like 1998 or so. It's mainly an office machine and it's the place where I like to compile all of my stuff into one organized place. I do alot of stuff on my iMac "Green Morpho" and I find it soooo annoying having to transfer the files floppy by floppy. I'd use flash drives but the mac is in...

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 .zip archive? Unexpected end of file?

Getting an "Unexpected end of file" or "There was a problem while reading the contents" error when trying to expand a .zip archive under Windows, Linux or even with an utility like The Unarchiver under Mac OS X? I was stumped to discover recently that, sometimes, Apple's Archive Utility app that is bundled with OSX is the only ZIP utility that can successfully expand those .zip files by ignoring invalid ZIP...

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...

Dealing with old apple hardware. Logic Board Serial Number issues.

Getting Started (WIP)

(the [messy] WIP guide) Hi enthusiasts 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 of...

HFS max partition sizes

In 1985, only a year after the first Macintosh came out, HFS (later referred to as "Mac OS Standard") was introduced and replaced MFS.  HFS required Macintosh System Software 2.1 and was welcome to support the HD20, Apple's first 20 megabytes hard drive that had just came out for the Mac 512K.  Can you imagine storing 50 floppy disks (400KB each back then) into a single device? Back in the day, this was huge! Now, we...

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

Here's how to make a bootable (or not) USB stick from a disk image in OSX using Disk Utility found under: Applications/Utilities/ You can use this cloning method to make a bootable Mac OS X install USB stick or an ASD one.

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 boot a Mac OS X installer without a DVD drive or an USB stick?

So you got a Mac OS X installer disk image (.iso, .toast, .cdr, .dmg) and would like to boot your PowerPC (G3, G4, G5) from it in order to install OSX, but unfortunately, the DVD drive on your old Mac is broken, missing or you're simply out of DVD discs? You instead went ahead and proceeded to boot your PowerPC Mac from an USB stick but it didn't work because the old Mac's USB ports are broken or the Open Firmware command fails for...

How to boot PPC PowerMacs (G3, G4, G5) from a USB stick or drive?

To boot a PowerMac (or an iMac, iBook, eMac, etc...) from an USB stick or drive, if you have a G5 or late G4 model, first refer to the boot from CD guide and if it does not work, then follow these instructions: 1.

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 convert any video to play it back on old an old 68K Mac w/ QuickTime 2.5?

Back in the early 90's, there was no such thing as 1080p let alone 4K! But playing back small color video on a 25mhz Mac was possible thanks to QuickTime.  It supported only a handful of formats, but here I'll explain how to get any video from today playing back on a 1990's Mac. First, I need some video conversion utility such as XMedia Recode. Then, I configure a conversion queue in XMedia Recode with very specific...

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,...
