MiNT OS


Do you fancy installing a version of MiNT on your Atari ST... but of course you do. So it's a good job a fella called Marcello has kindly created a ready-made disk image called "ST Mint" from his own installation of Cripple MiNT (w/ extras). All you need is a 4MB Atari ST, a cool Ultrasatan or similar and a spare SD card. Ideally, you should be using an ST-High display otherwise you will struggle in low or medium resolution...

Installation of Marcello's ST Mint is extremely easy and he has provided helpful instructions to recreate the disk image. Here are five simple steps for fellow Mac users:

1) download ST Mint disk image (scroll to the end for link)
2) insert the SD card into (if an alert appears, choose ignore)
3) open up Terminal.app and enter in three commands:
     3a) diskutil list (this displays the necessary information to identify your SD card - diskX on my iMac was disk1)
     3b) diskutil unmountDisk /dev/diskX (now that you know the device ID you can unmount it - but leave physically inserted!)
     3c) sudo dd if=st_mint-0.7.img of=/dev/diskX (dd is the command that transfers the data onto the SD card and will take several minutes. Enter your password and wait!)
4) now eject and insert the SD card into your ultrasatan
5) switch on the Atari ST and say hello to a baby MiNT OS

Here is a copy of my Terminal activity. As you can see, I entered the command "diskutil list" twice. Once before I inserted the SD card, and then again, so it's easier to see the difference:

iMac:~ ataricrypt$ diskutil list

This is a quick and easy way to install a pre-configured version of Mint. Of course, those that wish to tinker could instead install the base Cripple Mint installation? The choice is yours but whatever you choose, it might make you realize that MiNT was never actually intended for a slower TOS computer with little Ram. #justsaying
