Re: I worked with Danny for about a year, around 1974, sometime after UCSD put its B6700 onto the ARPAnet (we were something like the 35th computer). The AI community needed a BBNLISP with more addressing space than a DEC-10 could provide, so they came to the king of virtual addressing: the Burroughs. We got the contract to implement BBNLISP, and Danny came to oversee. I remember him typing on a terminal, linking UCSD to about 10 other computers on the ARPANET, finally linked back to us ... sending a message to himself. He was demonstrating the lag time each computer added :) IIRC, sometime during the project, BBNLISP was renamed INTERLISP. I still have the wonderful manual, with the great artwork on the cover. Warren Teitelman (the author) doesn't have his name on the cover. But, the bottom portion has a guy is operating a meat grinder, with the input being the letters of "reference manual" in random order, and the output being "reference manual". Danny explained that Warren Teitelman hadn't gotten the joke :) Danny was funny, quick witted, friendly ... RIP. Oh, UCSD LISP? About a week before we released it, DEC (or BBN?) had a breakthrough and increased the addressability of their virtual memory, obviating the need for our version :( Stan Sieler > >
