It is a Slinky. Cool card. Can be used by Appleworks in a IIe; increases your desktop space, or as a RAMdisk in a IIgs. I have a ROM 03 with slot 4 set to YOUR CARD and it in there. Works great! One cool use as a RAM disk; you can format it as either a 1024k disk and use it to store stuff when in use, or, as a 800k disk and use it as a place to unshrink *.sdk files. -Bart
