The root pack (linked to from my page): http://www.tuhs.org/Archive/PDP-11/Distributions/other/Tim_Shoppa_v6/unix_v… It contains lots of V6 goodies - but not, alas, source for most of them. (E.g. I had to disassemble the RL bootstrap(s) from it.) The others are junk (see below). To boot up the root pack (I don't think I did this at any point; I've always mounted it as a subsidiary drive) you'd need to say: mount dl0: unix_v6.rl02 /RL02 and then: boot dl0: The disk has a working RL bootstrap in block 0, it should boot OK. Then you get to take your pick of which unix to boot! There are 7 to chose from: 77 -rwxrwxr-x 1 root 38598 Aug 22 1984 oldunix 77 -rwxrwxr-x 1 root 38504 Jul 19 1984 oldunix.25.7 77 -rwxrwxr-x 1 root 38568 Feb 20 1985 unix 74 -rwxrwxr-x 1 4 36956 Mar 9 1983 unix.jones 69 -rwxrwxr-x 1 root 34408 Aug 16 1983 unix.mlab 76 -rwxrwxr-x 1 4 38316 Sep 3 1982 unix.rxrl 68 -rwxrwxr-x 1 root 33958 Jun 6 1983 unix.tmp and I have no idea how they all differ - or what each one expects to use for a root device and swap device. Looking at 'unix', it gives both rootdev and swapdev as '01000' (which is probably the RL, I'm too lazy to grovel around in bdevsw and make sure). The super block reports 19000 as the size of the file system, and sure enough, swplo is reported as 045070 (19000), and nswap as 02710 (1480). So it's probably set up to run and swap on RL/0. All of the other disks in the V6 folder with his name on it: http://www.tuhs.org/Archive/PDP-11/Distributions/other/Tim_Shoppa_v6 are junk; here's a brief rundown on each one: copy_num1_user.rl02: user0_backup.rl02: user_backup2.rl02: All very similar to the 'unlabeled' disk (below) - lots of random user files for biology stuff, little if anything of any use/interest. There is a file which isn't listed in the README: unlabeled.rl02: It looks like another /user disk, full of random biology stuff; nothing interesting except a copy of a nice-looking Kermit written in C (by someone at Columbia, IIRC). junk: An RL01 pack (the others are all RL02's); it has a boot block with PDP-11 code in it; I mounted it on a simulator and booted it, and it says it's an RSX-11M V3.2 disk. user01.rl02: This is also an RSX pack (I think), but when I tried to boot it, it said "THIS VOLUME DOES NOT CONTAIN A HARDWARE BOOTABLE SYSTEM", and since I don't know how to mount disks under RSX-11 I left it at that. scratch_disk_1123.rl02: This does indeed seem to be something that was used for disk diagnostics: the boot block contains gubble, including (in the first RL11 block) lots of words with all ones, and a lot of 52525's.
