How to make/clone/burn install/boot floppy disks for old beige 1990's Mac?

(Added on 2021-03-28 08:59:40)

This tutorial only applies to old Macs that have a regular 1.4MB floppy disk drive, NOT a 800KB or 400KB floppy drive.  800KB/400KB floppy drives were uniquely manufactured by Apple and cannot be emulated using a generic PC floppy drive at all, because they have special firmware in their boards that can pack more DATA per track than regular PC drives could, at the time.  So to make 800KB/400KB floppies, you absolutely need a beige Mac...

How to install Classic Environment (Mac OS 9.2.2) on top of Mac OS X

(Added on 2021-01-19 17:15:13)

How to manually install Classic Environment using a Mac OS 9.2.2 System Folder I suggest that you grab the first download "Generic Classic Environment for Mac OS X 10.4 Tiger" here because it fits most needs, but feel free to try another Mac OS 9.2.2 System Folder if you want.  Download it on your Mac OS X 10.4 (or earlier) computer and expand the .sit archive.  Then drag the resulting System Folder to the Mac's hard...

How to recover DATA from a failing hard drive?

(Added on 2020-12-28 16:17:03)

[WIP, coming soon] Hi.  Altough this guide has nothing to do with retro Mac technology per se, it could still prove to be useful to you, even if you are not using a Mac.  DATA recovery applies to everyone and it has nothing to do with what brand of computer you use, what type of storage media you use or even how old the storage media is.  DATA recovery is just DATA recovery, regardless of the computer. Basic technical...

How to display a custom StartupScreen picture on boot under Mac OS 9 and earlier?

(Added on 2020-03-06 14:50:04)

Under Mac OS 9 and earlier, all the way back to the first Mac OS versions in the 1980's, you could display a custom boot picture in the background while Mac OS was loading. To do this, you do NOT need to alter/edit any system files at all.  All you need to do is to save a copy of your desired startup picture into a specific format and place it in your System Folder. Note: System 6 and earlier only supports black & white...

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

(Added on 2020-01-16 08:46:25)

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 wrap loose old Mac files into a disk image (for use with FloppyEmu, etc...)

(Added on 2019-09-16 09:24:02)

OK, so you got yourself FloppyEmu or a similar disk emulator for your old Mac and it works great, except not with all the files.  Why? Because FloppyEmu and such disk emulators are... disk emulators.  They expect you to feed them a disk image, not just random loose files. So just how can you wrap loose Mac files inside a disk image for use with FloppyEmu? Here's a full tutorial: 1) Grab a copy of this Disk image wrap tutorial...

What is a .dsk file (DiskDup image) and how to use it?

(Added on 2019-06-07 17:05:35)

What is a .dsk file? A .dsk file is a DiskDup image, an exact copy (sector by sector) of a floppy disk. DSK images were a popular format for cloning or duplicating 1980's and 1990's Macintosh floppy disks.   How to use or extract DSK images contents?

Getting Started (WIP)

(Modified on 2019-03-19 12:21:04)

(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 of...

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

(Added on 2019-03-17 16:52:31)

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...

(Added on 2019-02-27 12:56:36)

What is a .rar file? A .rar file is a RAR archive, much like a ZIP file, except it's a proprietary format mostly used under the Windows environment.   How to use or extract .rar archives contents?

What is a .dmg file (disk image) and how to use it?

(Added on 2019-02-20 10:49:17)

What is a .dmg file? A .dmg file is a disk image, meaning it's an exact copy (raw block DATA) of a disk (CD, DVD, USB stick, etc...) or even just a folder wrapped in a disk image. DMG images have been the default file format for distributing software on the internet for Mac OS X users since the year 2000.  DMG images are safe to store on any partition type, such as Windows (NTFS) and are safe to distribute over FTP, send by email,...

What is a .iso file (disk image) and how to use it?

(Added on 2019-02-20 08:48:21)

What is a .sit (Stuffit) file and how to use it?

(Added on 2019-02-19 08:43:49)

What is a .sit file? A .sit file is a Stuffit archive, much like ZIP files today, except that .sit is a proprietary archive format from the 90's which allowed Mac users to confidently "stuff" their files, applications and documents into a flat file that could then be copied to a non-Mac hard drive partition, namely a DOS (FAT32) or Windows (NTFS) partition, without any risk of DATA corruption.  You see, throughout the...

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

(Added on 2019-02-11 12:54:25)

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...

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

(Added on 2019-01-28 08:47:51)

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.  

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

(Added on 2018-12-12 11:26:16)

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 be useful to you.  It will let...

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

(Added on 2018-10-30 10:28:24)

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,...
