Pearl: Information about Pearl Lisp

When Apple Computer acquired Coral Software in January 1989, they re-released Coral's Allegro Common Lisp and its optional modules as Macintosh Allegro Common Lisp (now just Macintosh Common Lisp). Coral's other product, Pearl Lisp, was discontinued at that time. Pearl Lisp provides a subset of the functionality of MACL 1.3 and is not even fully CLtL1-compatible (e.g., the implementation of defstruct is different). Despite rumors to the contrary, Pearl Lisp is not and never was public domain. Nevertheless, Pearl Lisp and its documentation were placed in the "Moof:Goodies:Pearl Lisp" folder on the first pressing of "Phil and Dave's Excellent CD", the precursor to the current Apple Developer's CD-ROM series. Apple removed Pearl from later versions of the developer CD-ROM distribution because of complaints from other Lisp vendors. If you own a copy of Pearl Lisp or a copy of this CD-ROM, you can make it runnable under System 7 with some slight modifications using ResEdit. To repeat, Pearl Lisp is NOT public domain, so you must own a copy to use it. To make it runnable, one needs to use ResEdit to make changes to the BNDL and FREF resources so that it will connect to its icons properly. This will make it respond to double-clicks in the normal manner and make it be properly linked to its files. Detailed instructions for modifying Pearl Lisp using ResEdit are included in this directory. After you've made the changes, it will run under System 7 on 68000s and 68030s if you turn off 32-bit addressing. It seems to bomb on a Quadra. If you need a more powerful Lisp or one that is compatible with the standard for Common Lisp, consider purchasing Macintosh Common Lisp.
