I have ported simh 3.8-1 to plan9. It currently has the following issues 1. Since I am on christmas break, i dont have access to my cpu server. all testing was done on 9vx 2. 9vx seems to do wierd stuff if you keep the cpu load at 100% for too long, so i had to implement a simple idling routine. set throttle also works but i preferred having a dynamic load change.( i'm using rons 9vx bitbucket stuff by the way.) 3. simh had it's own idling, but it looked like I needed to get into the code deeper than I thought is necessary. 4. compiling the pdp10 seems to kill 9vx. compiling vax still had a few gnu-ish preprocessor directives that prevents it from being compiled. 5. I dont know much about socket programming so i am not sure if it's working. When I try to run it with telnet it cannot open up a port. I will proabably send a separate email asking about ape sockets later.
to build gunzip simh-p9.tgz tar x simh-p9.tar cd simh-p9 plan9/build this only compiles the ones i care about excluding pdp10 and vax plan9/build_all tries to build everything. http://plan9.bell-labs.com/sources/contrib/fernan/simh-p9.tgz
