This is a read only ProDOS compatible bootable drive that can hold 1024 KB of data that start in just a couple of seconds! The ProDOS ROM card is preprogrammed with ProDOS, and 25 popular Apple II games. It's read-only: to change the content you need an Eprom programmer and the freeware utility CiderPress to create your own ROM.

This expansion card may be used in any of the Apple II expansion slots. Please make sure the Apple is powered off when adding or removing the ProDOS ROM card. Take note of the correct orientation of the card (EPROM towards keyboard).

Every unit is tested, before shipping, on an Apple ][e. New, with gold ENIG finish.
