He had been wanting to do something with the Seagate Dockstar and decided it would find a nice home in the Mac. But what fun is … Read the rest

Emulating an Amiga floppy drive

[Retromaster's] Ultimate Floppy Emulator is a wicked display of hardware mastery. It is the culmination of several design stages aimed at replacing an Amiga floppy drive with a modern storage solution.

[Wehrdo] has posted a guide with an extremely low-tech solution to password management. He literally put the passwords on a floppy disk in the form of paper glued to the magnetic film. For those that still have some floppy disks around, this is a zero cost hack. We wouldn’t recommend this for state secrets, but for those prolific forum … Read the rest
