This directory contains applications written specifically for particular versions of UNIX on PDP-11 systems. You will find sources to many contributed applications in the various 2BSD distributions in the archive. Note that many of these will be difficult to back-port to earlier versions of UNIX (e.g 6th & 7th Edition). Other places to look for PDP-11 UNIX software are the on-line archives of the comp.sources.unix USENET newsgroup. One such archive is at http://ftp.digital.com/pub/usenet/comp.sources.unix/ This includes volume 1 through 29; the stuff in volume 1 is dated 1986.
