IDE to SD Quickstart (Draft)
The following guide is designed to get up and running quickly with a IDE to SD adapter when you don’t have any installed OS on your antique IDE (aka ATA) Macintosh such as the Quadra 630.
The following are required :
- An IDE to SD adapter board
- A copy of the program Etcher
- An SD card of at least 2GB
- An elderly Macintosh with an IDE interface (laptop or desktop)
- A modern computer (MacOS X, Linux or Windows)
I have two different types of IDE to SD adapter, although I’ve only used the smaller type as I use one in my Powerbook. The first example has a smaller laptop style connector. The second has a full size IDE connector. If you get the laptop variant, you can get adapters for your adapter.
Download the following disk image onto your modern computer. This contains both a “Restore” partition with a bootable copy of Mac OS 7.5.3, installation disk images for Mac OS 7.5.3 and some utilities etc. to make life easier, as well as a second 1.8GB partition with a System 7.6.1 installation and not much else.
ATA Version of 7.5.3 Restore, plus Macintosh SD 7.6.1 partition (~59MB download)
Unzip the disk image in the download and save it somewhere handy, such as the desktop.
Install Etcher, insert your SD card into the modern computer, launch Etcher and follow instructions to select the downloaded disk image and your target SD card. Take care – you don’t want to flash it to your computer’s hard disk!
Once the card is written, eject it from your modern computer. Place it in the IDE to SD card adapter and insert it into your retro Macintosh.
That should be it – you should be able to boot from the disk. You’ll need to add additional partitions if you want to use the rest of your SD card if it is bigger than these partitions (~1.9GB), but I’m not sure what the best software is for this with an IDE disk – probably HDT or similar.
