[pups] Looking for binary distribution of v7

Hello, I just read the instructions of how to boot a binary version 7 disk image on a ersatz11 pdp11 emulator. The links pointing to the 'unix_v7_rl.dsk' image I found are dead ... :-( Are there any other sites where I can download this binary distribution ?? BTW their are disk dumps of version 7 in the Caldera ancient unix archive .. is it possible to boot them on ersatz11 as well ? I tried it a few times without success ... I simply tried it with the following e11.ini (from a newsgroup discussion), because I heavily lack PDP 11 hardware knowledge. Nevertheless trying this ini-file and many variations I made of it all end up in a blank emulator screen ... Any ideas will be appreciated Mario Premke ; Set up some terminal devices assign tt0: f1 assign tt1: f2 set scroll hard ; Make the CPU like an 11/45 set cpu dspace set cpu dualregset set cpu mmtraps set cpu pirq set cpu spl set cpu supmode set cpu cpuerr set cpu csm set cpu tstset ; Get rid of unneeded device delays set delay dl11 0=0 1=0 set delay rl11 0=0 1=0 2=0 3=0 4=0 5=0 6=0 7=0 ; Mount the RL02 disk image mount dl0: v7_rl.dsk ; and boot boot dl0:
