I used this in the 1980s and would like to get a replacement copy for the one I lost - thanks. Last year on eBay someone purchased a large collection of Macintosh diskettes, one of which was an ExperLisp diskette, so if that person is a cctalk-er I would appreciate a reply. It was released for the Mac 512K and later Macintosh.
