The ProDOS RAM disk driver is in the December 1985 issue. The title is "ProDOS and the RAM Disk," by Alfred Steele, page 84. But the driver is designed for the Synetix Flashcard with 288K of RAM. The Flashcard has six banks of memory. Four banks have 64K and the other two have only 16K each. Also in this same December 1985 issue is an article called "Adding a Copy Command to ProDOS" by Shawn Day. -- ]DF$ The New Apple II User's Guide: https://macgui.com/newa2guide/
