From mboxrd@z Thu Jan 1 00:00:00 1970 From: newsham@lava.net (Tim Newsham) Date: Tue, 6 May 2008 21:04:26 -1000 (HST) Subject: [Unix-jun72] DC-11 quick hack Message-ID: Ok, I had some initial success with a quick and dirty hack. - apply the attached patch to your simh tree and rebuild pdp11 and copy it into your tools directory. - maps the TTIX device into the DC11 space - forces the CSR to return the carry-detect bit as always on - edit build/init.s and uncomment some or all of the ttys build it and place it on your drive: $ vi build/init.s $ tools/as build/init.s $ cp b.out build/root/etc/init $ tools/mkfs -p fs/Readme build/root rf0.dsk rf - copy your simh.cfg to simh2.cfg and add these lines before the "go" line: set ttix en set ttix lines=8 att ttix 5555 - run "./simh2.cfg" at this point you can telnet to port 5555 and enjoy a multi user unix system. This lacks a lot of polish and needs a bit of work yet, but its quick and dirty. You'll have to revert to the old init if you want to use the normal simh.cfg since the kernel will panic when opening the other ttys if the DC11 hardware isnt attached.
