Hi folks. Having had absolutely no luck getting the Begemot emulator to work under FreeBSD 4.0-CURRENT, I've been modifying the Supnik 2.3d emulator for the pdp-11. So far, I've replaced the KL11 code with a DL11 driver that handles four lines. Additionally, I stole the networked tty_net driver from the begemot which now provides telnet access to all four ports. Additionally, I'm working on a DZ-11 driver as-we-speak, and will do the DEQNA next. These four ports work great on the RSTS/E and 2.11 images I have. As well, I've tweaked the clock timing to significantly improve timekeeping for my machine. Also, I have been modifying an ANSI magtape util package (ansir/ansiw/survey) to deal with the mt images that the supnik package produces. Makes for easy exchange into RSTS, etc. Is anyone else out the hacking it up and interested in sharing any work? And if anyone has managed to get the Begemot emulator working on recent FreeBSD-4.0-CURRENT versions, I'd be grateful if you could share the information and changes with me.

Hmmm, the Begemot emulator is difficult to set up due to an inscrutable configfile format but it runs here under BSD/OS 4.0.1 after making a couple 'tweeks'. I wonder if the problems you're having are due to FreeBSD switching to ELF. At one time BSD/OS used a.out also and "P11" built/ran just fine - the the OS switched to ELF and P11 would no longer build. I had thought simply editing the instab.s would be enough but after doing that P11 wouldn't run right at all. What I did was add a "-u" option to 'geni' and then regenerate the instab.s file ("geni -u ...") _without_ the underscore characters present. The compiler no longer generates leading '_' characters so having them in the instab.s file causes problems. Regenerating and assembling instab.s cleared up all the problems I was having. Below are the changes I've made to P11 - some are specific to getting the various IOprogs to run under BSD/OS but the changes to geni.c are OS independent. THe other change I had to make was to 'devices.c' to speed up the clock - it's still not right for a PPro-200 but is better than it was (the clock was running far too slow, now it's just ~10% too slow). Not FreeBSD but if you're getting bit by the same thing I did earlier under another BSD that switched from a.out to ELF the changes below may be useful to you.

You might try using the 2.11 images from the PUPS CD instead. Create a "tape file" (the instructions are in the 2.11 distribution directory) and then use a "toggle in" bootstrap for the "mt" device. The config file I use for this is: set cpu 22B set cpu 2048K set rp0 rp06 set rl0 rl02 set rl1 rl02 set rl2 rl02 set rl3 rl02 set tm0 locked at rp0 rp0 at rl0 root.rl02 at rl1 usr1.rl02 at rl2 usr2.rl02 at rl3 usr3.rl02 at rk0 junk0.rk05 at rk1 junk1.rk05 at rk2 junk2.rk05 at rk3 junk3.rk05 at rk4 junk4.rk05 at rk5 junk5.rk05 at rk6 junk6.rk05 at rk7 junk7.rk05 at tm0 mt0 at tm1 mt1 # at tm1 /zip/mt0 Place your "2.11 boot tape file" (the 'makesimtape' program which is also available in the archive and on the CD is used to create Supnik emulator tape files) in to the file "mt0" and then follow the instructions in the setup/install documentation on how to boot a tape if you don't have tape bootroms (it's less than a dozen instructions you need to toggle in the octal for). Oh - and since the "RP06" disk is just an image to the host computer (to the PDP-11 it is a RP06 ;)) the image IS interchangeable between emulators - I've used the same RP06 image under both (obviously not at the same time) the Supnik and Begemot emulators. Works fine. The biggest problem with the Supnik emulator is that the clock runs far far too fast (at least with a PPro-200 running the emulator) and after running for an extended period of time the PDP-11 system ends up several hours in the future.
