Description

APPLE II ProDOS ROM Drive

This is a peripheral card for the Apple ][ series computers that acts as a read-only solid state disk drive (SSD) all in EPROM. Although it won't run DOS, it is fully ProDOS compatible and will appear as a read-only hard drive even when booting from another drive. It holds 1022 KB of disk data and 2 KB of controlling code making a full megabyte. The drive boots ProDOS and into BASIC in under 1.5 seconds.
