DEC odds and ends

by mxs46＠k2.scl.cwru.edu

Dear PUPS/TUHS members, I have just created a new directory in the 4BSD area of the PUPS archive, Distributions/4bsd/odds-ends. This directory contains various DEC odds and ends: microcodes, ROM images, diags, VMS/Ultrix booters and bits, etc. The following items are currently available: rabads.core Ultrix rabads program, pure core version for putting onto console media and loading via console commands. rabads.a.out Ultrix rabads program, a.out version for putting onto a UNIX filesystem and loading via UNIX boot. scsimfm.bin EPROM image from the SCSI/MFM daughterboard for KA42. This list is certain to grow very soon. Sincerely, Michael Sokolov Phone: 440-449-0299 ARPA Internet SMTP mail: mxs46(a)k2.scl.cwru.edu

I type: "tmrk", it just freezes. The 6th Ed installation instructions say: The tape contains 12100 512-byte records followed by a single file mark. Have you made the tape image for Bob Supnik's emulator to match this, and what configuration file are you giving to the emulator?

I type: "tmrk", it just freezes. You're following the wrong instructions. :-) Or, at least, you're taking them too literally. You're trying to use the tape the way it would be done on a real machine, but it's much easier to just split it into disk images under the host UNIX. Looking in my V6 directory, I've got a text file containing something that I believe Warren wrote, in a text file accompanying the tape image: "This is a copy of the Sixth Edition distribution tape which was sent to me by Ken Wellsch. The file v6.tape.gz is the tape image, with the first 100 512-byte tape blocks containing tape bootstrap stuff. Blocks 100 - 4099 are the RK05 root image, blocks 4100 - 8099 are the /usr RK05 image, and the blocks 8100 - 12099 are the /doc RK05 image." So what I did with that tape, for Bob Supnik's PDP-11 simulator, was to run these commands under the host UNIX: % gunzip v6.tape.gz % dd if=v6.tape of=v6.root.rk05 count=4000 skip=100 % dd if=v6.tape of=v6.usr.rk05 count=4000 skip=4100 % dd if=v6.tape of=v6.doc.rk05 count=4000 skip=8100 Then, I made a script file for the simulator: % cat > v6.script attach rk0 V6.root.rk05 attach rk1 V6.usr.rk05 attach rk2 V6.doc.rk05 boot rk0 ^d % ...and finally, I run the resulting system, thus: % pdp11 v6.script PDP-11 simulator V2.3 @unix login: I may have had to modify something in the actual UNIX V6 system to mount rk1 and rk2 properly -- I don't recall. You'll figure it out. Anyway, the system runs like a charm, and I've successfully rebuilt the kernel from sources on it. Fun!

One of the new pieces is a hard drive, which allows me to write assembly code with the RSTS/E Macro Assembler, write them to the hard drive, and boot the system up in non-RSTSish ways... I'm new to PDP-11 assembly language, however, and I don't have a really complete manual... The general purpose registers are all 16 bits. Addresses stored in these registers can only point to the first 32K words of memory. My PDP has a 512K words of memory. The only reference I've seen to this problem was one sentence in one of my manuals that says the rest of the memory can be addressed through "memory management". When it says this, does it mean that there is a separate memory management unit that I have to control to flip between pages or banks of memory, or are there extended registers in the CPU itself that allow me to do this? I crashed the machine the other day and I noticed that the monitor listed some registers that started with M... Could that be what these are for? (The computer claims to have 22-bit addressing, BTW.) -- Erin Corliss

Intruiging bits in the nsys kernel

by norman＠nose.cita.utoronto.ca

Some answers to Warren's queries: mknod(II) first shows up in the Fourth Edition; the manual entry is dated 8/5/73. (That having been typed in the US, presumably it means 5 Aug 1973.) getgid(II) shows in the same manual, but with an older date: 3/15/72. This is also the edition in which the documentation for stat(II) first admits a group ID as well as a user ID. Both my hazy memory (made worse by lack of sleep right now) and the clues in the manual suggest that 3e/4e was the period when the system was rewritten in C; e.g. 4e is the first to show C interfaces in section II, complete with structs as well as pure byte-offset descriptions for objects like that filled in by stat, though the structs are nameless, presumably because there were no standard header files yet. Evidently the file system upheaval occurred in the same period. Reading the description of the 3e file system, I see it has been too long since I've read it. A summary: Blocks 0 and 1 are the super-block, consisting of size of free-storage bitmap the map itself size of free-i-node map the map itself Block 2 begins the i-list; data blocks follow. I-nodes 1-40 are reserved for special (device) files, and don't appear in the map. I-node 41 is the root. I-nodes have flags, a link count, a userid, a 16-bit size, creation and modification times, and eight block pointers. Flag bits inclode `allocated', `large file' (the pointers are to indirect blocks), read and write permissions for user and other, set-userid, a single `executable' flag, a `directory' flag (if clear, regular file). BUGS Two blocks are not enough to handle the i- and free- storage maps for an RP02 disk pack, which contains around 10 million words. The 4e file system is more or less that in the more-familiar V6 system: Block 0 reserved for boot block Block 1 is the super-block: file-system and i-list sizes, caches of free block and i-node numbers. The free-block list is now the familiar chain of blocks list free block numbers; the free-inode list is abolished because the i-nodes all have `allocated' flags anyway. Block 2 begins the i-list. I-node 1 is the root. I-nodes differ from 3e in having a group ID,a 24-bit size, access time instead of creation time; the `directory' flag becomes a two-bit `file type' flag; group permissions appear, there are three separate `executable' flags, and set-group-ID appears. No BUGS yet, perhaps because the code was new. Notice how history repeats: 4e replaced the free-block bitmap with a list, which made it simpler to cope with huge file systems but harder to allocate blocks in a simpler order; sundry replacement file systems in the early 1980s (Berkeley FFS, Weinberger's cheap hacks in V8) restored the bitmap, because it's easier to pick a good block when you can see all the blocks available, and because by then computers had enough memory and disks were big enough that a large bitmap wasn't a burden. An anecdote may be (barely) relevant here. I remember once in the late 1980s having a chat with Lee McMahon about group IDs, and how they didn't seem to have done quite what people wanted (hence the multiple-groups-per-process stuff in most current systems, and the special semantics for the set-group-id flag on directories, and various other features that have seemed to me never to quite hit the mark). Lee told me that when Ken first put group IDs into the system, he asked Ken what they were for. Ken allegedly shrugged and said `I dunno.'

Intruiging bits in the nsys kernel

Eric is quite correct, and I realised this after reading some comments on the V2 kernel. The nsys kernel also has a sig() system call which allows a process to trap an arbitrary signal. This is why the syscalls above were removed: there was a more general system call available. > > > Syscalls in V5 but not in `nsys': > > --------------------------------- > > 0, &getpid, /* 20 = getpid */ > > 1, &smdate, /* 30 = smdate */ > > 0, &nice, /* 34 = nice */ > > 0, &pipe, /* 42 = pipe */ !!! > > 4, &profil, /* 44 = prof */ > > This part seems really weird.

This just gets stranger and stranger... > eric I've had some chat with Dennis about this kernel, and how it fitted into development. The summary is: Ken tried to rewrite the assembly version of the kernel in B (or NB) in 1972, but gave up because structures didn't exist. Once B -> NB -> C and got structures, they tried again. Apparently, the `new' kernel (aka nsys) was developed in parallel with the `old' assembly kernel during early to mid-1973. Then, Dennis says: I'm pretty sure that we didn't adopt [the C version of the kernel] as the standard "production" system until about September 1973. It is very likely that the real "sys" was still in assembler. Pipes were probably added first to [the sys] version, given the evidence in "nsys." Dennis also says: During 1972, Ken finally puts pipes into Unix at McIlroy's urging. which would explain why there is a reserved syscall in `nsys', but no code as yet. I can't explain the existence of the mknod(), getgid(), and setgid() system calls. Norman and Bob Keys, I think one/both of you have got the old manuals, can you look through them and find out when these syscalls appeared?

They said yes, so I was wondering if anybody might want to be co-author. This is what I suggested: > I'd like to write an article which describes the efforts to find and > preserve historical material which is related to UNIX. This includes > finding tapes, reading them, decoding their formats etc. > > The article would also discuss the mechanisms available for running > these old UNIX systems: by using old hardware (and the difficulties > of maintaining such equipment), by using software emulators (and > possibly a discussion of what they provide). > > In other words, the actual history of UNIX and its influence would not > be covered, but the `archaeology' and preservation of artifacts from > the early days of UNIX would be. Given that there are people on the list who deal with old hardware, reading ancient tapes, etc., I thought they might like to add some input to the paper. I think the paper size is limited to around 25-30 pages, and has be formal in tone. If anybody has any suggestions as to what should go in (or even wants to write a section), then I would welcome some email! Cheers all, Warren P.S I'm giving a similar, but much more informal, paper at a local conference next month.
