At the June 1996 Gravenstein User Group meeting, Joe Kohn gave a demonstration of the Mark Twain — the Apple IIGS “ROM4” prototype that Apple Computer chose not to bring to market.

The presentation has been in limbo for all these years, until now. As part of preserving Joe Kohn’s legacy of distinguished service to the Apple II Community, the video has been made available by his friends.
