RamDisk is an Internal RAMdisk utility.

> RamDisk+ is a system INIT (Control Panel) that allows you to set
> aside some portion of the memory inside of your Macintosh computer
> and use it as though it were a file storage device such as a floppy
> disk or a SCSI hard disk.
>
> The reason for using such a mechanism is to gain the very high speed
> file access that a RAMdisk affords you, or simply to have more on
> line storage. For those users without a hard disk, the speed gained
> over a floppy disk is dramatic, and for those who have only on
> floppy disk drive, the use of a RAMdisk is almost essential.
>
> RamDisk+ has been written to automate as much as possible the start
> up of the Macintosh when an internal RAM disk is desired. All
> controls of the program are remembered, so that once set, the INIT
> will run quickly each time you start your Macintosh with no user
> interaction required.
