Index It's all still preliminary and there are some bugs but both it and (possibly) ts10 (another simulator) have finally reached the stage where they can boot TOPS-20. They've been able to boot TOPS-10 for some time but TOPS-20 required more floating point support. I actually had tears in my eyes when I saw "System restarting, wait..." The last time I saw that was in 1990 with the "SYSTEM OVERRIDE" switch toggled to override failing fans just to boot one last time before it was wheeled out the door. Most of the old DECUS tapes are online and available for download so we can start programming in Simula again :) Some of the info needed is all over the place but a good start point is http://www.aracnet.com/~healyzh/pdp10emu.html and the alt.sys.pdp10 newsgroup. Just in the last week or so pre-built binaies have been made availble for WIndows and the emulator claims to be able to compile and run under VMS but I haven't tried that yet. -- Alan
