Who would have thought that in 2013 we'd be able to recover source code for APL from the late-1960s/early-1970s! I have uploaded the source code to CHM's Software Preservation web-site. In addition, I've uploaded the original Tech. Report from Gary Kildall (pre-CPM era) describing the system, user manual from Georgia Tech and Nigel's announcement email. It joins the source code for APL implementations for the SDS Sigma Series and Paul McJones micro-coded APL from Berkeley. </blockquote> It also joins the source code of IBM's 1969-1972 version of APL that we released last October: <a href="http://www.computerhistory.org/atchm/the-apl-programming-language-source-code/"> http://www.computerhistory.org/atchm/the-apl-programming-language-source-code/</a> By the way, in May we received permission from Apple to release the source code of Apple II DOS from 1978. And last Friday I signed an agreement with Microsoft for the release of the source code of Microsoft Word version 1.1A. Stay tuned for both of those. -- Len </body> </html>
