I can speak to the v6 stuff, and I think the same applies to the v7 stuff: the bootable image rkunix is intended to allow you to get a system booted from an RK05 (on which you've presumably installed this image), so that you can rebuild the system to suit your hardware. There is some special stuff in v6 for the PDP-40, so presumably the rkunix.40 image addresses that. The 'unix' image is the image one customarily boots to use the system; it's probably the image from the system on which the image was originally built all those years ago, and is intended to be replaced by your new image. Presumably, the drivers in that image might be identified if the c.c and l.c files are still present in /usr/sys. I don't know whether Bob Supnik actually built these images, or (as I suspect) included them from e.g. the PUPS site. Regarding the v7 stuff, I think you'll find considerable information in the v7 setup docs on the PUPS website, as to which corresponds to what drives (although it's somewhat self-explanatory).

Can anyone tell me (or give me the adb commands to figure it out myself) what disk device drivers are present in the bootable disk images that come with the Supnik simulator? The versions I'm interested are: V6 image: - rkunix (rk) - rkunix.40 (rk, PDP-11/40 cpu?) - unix V7 image: - hphtunix (hp) - hptmunix (hp) - rkunix (rk) - rl2unix (obviously hacked to include rl driver) - rphtunix (rp) - rptmunix (rp) Matthew (mrw(a)apple.com) _______________________________________________ TUHS mailing list TUHS(a)minnie.tuhs.org http://minnie.tuhs.org/mailman/listinfo/tuhs
