this are two versions of an unknown lisp-interpreter I found on two of my DEC-tapes, labeld Kopenhagen'78. I believe, that at that time there was eventually an DECUS-symposion? Both lisp-versions are very similar, eventually the startingaddress in the CCB is wrong. Perhaps they start at address 13000? The files were transmitted with KERMIT-8 in binary mode. I tested retransmitting LISP16.SV to my PDP8/E. It loaded succesfully. The .EN-files in this directory were encoded with Charles Lasners ENCODE-utility, they can be decoded with the corresponding DECODE-utility, if transmitting of binary files is problematic. Please give me feedback if you succeed in running one of the two programs. 8-OCT-15 Klemens Krause cm@informatik.uni-stuttgart.de
