Although some here may recognize me from the PDP-11 newsgroups, I am a new member of the mailing list. And I come with a problem right off the bat!! Is there anyone here who can give me hand figuring out how to get more than 1M of memory working on an 11/23+ and an 11/73?? This has me pulling my hair out!! I have a couple of M7551 4M modules but can't seem to make them work beyond setting them for 1M. I have Ultrix-11 3.1 running (even with TCPIP!) and really would like to get more memory so I can make them functional rather than just running. Is there anyone here who can offer any help. And as long as I have everyones attention, anyone here who knows anything about the H777 power supply in the 11/24?? I've got a dead one and I really miss my only UNIBUS machine. Come to think of it, it would run ULTRIX-11 pretty good as well if I could revive it. Any help greatly appreciated. bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n.

[pups] BSD2.11 Floating Point Simulator

by Robin Birch

Dear All, I am currently looking at making the 2.11 FP simulator work. Unfortunately I don't have a non floating point PDP to check things on. Can some one who has please try running some FP code on the Generic Kernel for 2.11 and let me know what happens. I am slowly going through the code but some symptoms would be useful. regards Robin ____________________________________________________________________ Robin Birch robin(a)ruffnready.co.uk M1ASU/2E0ARJ/M5ABD Old computers and radios always welcome

[pups] 9 track reelers on MVII.... will an IBM differential drive work?

by rdkeys＠unity.ncsu.edu

On a lark, my ol' propeller headed beanie was whirring, again, today. Problem: how to use old IBM differential scsi reel tape deck to make reel tapes for antique unix.... Discussion: I picked up a perfectly fine looking IBM 9348-001 differential scsi interface tape deck from an AS400 box. I had thought of using a differential to single-ended scsi converter, but, they are a tad dear for this olde man's beer bellie peanut computer budget. Thinking there had to be some other way of making use of this deck to write some fine old reels, I saw, buried deep in the pdp-11 cards list a differential tape card by Dilogic, and though... hmmm, can the old MVII crank out to the 9 track via such a card? Solutions: anyone have any insights on trying something like this or know if such a shennanigan will work? Are there any other such differential scsi cards available that might work? Anyone got such a critter gathering dust? Is this really a scsi card or is it some other interface? Thanks Bob

I have been thinking of trying to find a PDP-11 of some sort (like hunting for needles in a hay stack in this part of the woods, but maybe something will surface). Anyway... for the sake of discussion, and general dumpster diving knowledge.... 1. What mfm hard drives from the non-DEC world could be adapted to work on a PDP-11? 2. Can any scsi drives be used (RZ-23's or that kind of thing?). I often run across lots of smaller DEC scsi drives in MooU surplus, as well as assorted MFM drives from retired AT crates. IF I can find out what is worth saving to use, that would be great info to have handy, whilst dumpster diving. At a buck or two a chassis, it is worth saving a few drives, provided I know what to save. I will assume the target OS is 2.11BSD or 2.9BSD, since those seem to handle the greatest assortment of hardware types. Can any of these non-DEC drives be adapted to MVII use? Can any of the early MFM or ESDI Sun drives be used? I vaguely remember some notes on some of this somewhere. Any urls or pointers thereto would be appreciated.

VAXen are the usual fare, since PDP's were not that common around here. The RTP NC area did not really get big into computering until the VAX era. > > 1.

Used CMD, Emulex or Dilog > controllers will run around $500-900. I fell into a MVII yesterday that has a Dilog controller. Is that the one you are talking about? If so, that could be a lucky find. Here's a crazy, but possible thought.... can I write 211BSD drives from a MicroVAX II and move the card/drives over to the PDP-11 and have a reasonable expectation that they will work, or at least boot to a root or a miniroot or such? It is a long shot, but if I am just dd'ing images, it might work, I would think. One of my goals with the MVII is to use it to write 9 track tapes, IFF I can lay hands on one of several 9 trackkers in surplus in the next few weeks. They were originally used on a local VAXsystem 5400 crate and are single ended scsi Ciphers. Could they be used on a PDP-11, too? > Once you have gotten over the sticker/exchequer shock the upside > is that you can use about many SCSI disk or tape drives that other > folks are tossing otu because they're too small.

All the PeeCee types avoid them like the plague, and I truck them out by the handfull. MooU was big on those and DS5000/200 crates.

RD53 is a Micropolis 1375 (eh, no the MFM variant of it.. 75 is SCSI. Maybe 1325??). RD54 is a Maxtor or Newbury data drive. I can look up the details if needed. As far as MFM drives go I would not consider anything smaller than a 53. -- Wilko Bulte wilko(a)freebsd.org Arnhem, the Netherlands Received: (from major@localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id JAA06732 for pups-liszt; Fri, 13 Oct 2000 09:51:34 +1100 (EST) (envelope-from owner-pups(a)minnie.cs.adfa.edu.au)

There is a Macro-assembler, and reportedly a PASCAL compiler. However, my Micro/RSX skills (let alone -programming skills) should be considered rudimentary - the only resource I have is the on-line helpfile (which isn't very clear every now and then). > If you've a PC with a 5.25" drive and the ability to do image copies > to it ('dd' on a *BSD* or Linux system) that might be one way to > get 2.11 over to the MicroPDP.

The "RX33" is working (that's how I was able to low-level format two MFM disks, and how I got Kermit running). And yes, I have a Minix-VMD box with a 5.25" HD drive.

Something like that), a second 21MB MFM disk standing by (A microscribe of some sort), a 5.25" PC floppy drive shoe-horned into a RX33, and a DELQA card. (Well, that's what I have installed right now.

It is going to take some creative symlink and mount point work to fit 2.11 into 20MB disks - the system really expects to have ~80MB at least for /usr. An RD54 at 159MB is more than enough but a RD53 paired with a couple RD32/3 would be adequate. Steven Schultz sms(a)to.gd-es.com

[pups] How to arrange bootable media for 2.11BSD?

by Martijn van Buul

Ahoy! I've about given up hope to create a 2.11 boottape myself[1], so I'm wondering what to do next. I have this MicroPDP, with a DELQA network card, a PC 5.25" diskdrive shoe-horned into working as RX33 and a TK50 tape drive. If it helps: I've managed to get Kermit running on the PDP, but I haven't figured out if it is possible to "kermit" to the tapedrive directly. Probably not. Any hints? Kind regards, Martijn. [1] My hopes have vaporized into thin air by two "not so overly bright" persons. One of them decided that the TKZ-50 drive we (the local user group) had should be split into controllerboard and actual drive (and stored seperately), the other one didn't recognize the TKZ50 controller, couldn't figure out what it was used for, and threw it away...

I have this MicroPDP, with a DELQA network card, a PC It is an 11/53 or better (73, 83, 93)?

Probably > not. What OS did you manage to get Kermit running under? I do not believe Kermit itself can handle the multiple block sizes used when writing the files that make up the "boot tape". Do you have any development facilities on the currently running system? If so then it might be possible to write a program to create a tape from the files brought over via kermit. > Any hints? First shoot the individuals mentioned in [1]? ;) If you've a PC with a 5.25" drive and the ability to do image copies to it ('dd' on a *BSD* or Linux system) that might be one way to get 2.11 over to the MicroPDP. A single RX33 can easily hold the standalone programs (boot, disklabel, restore, mkfs, icheck) and it only takes 3 or 4 RX33 disks to hold a root filesystem dump. The bad part is that the GENERIC kernel lacks networking due to space contraints. Someone would have to create a custom kernel+ networking root filesystem and create 3 or 4 RX33 images to be dd'd out to floppies. Then, once a networking based root filesystem was loaded it should be possible to get pull the remaining data over the network with a "rsh ... | tar ..." command. Much depends on the ability to create floppy disks from images on a PC that can be read on the RX33 which the PDP-11 has. If that works then the rest will be timeconsuming (and the install instructions will of course be heavily modified ;)) but at least possible. Steven Schultz sms(a)moe.2bsd.com

The default clock rate on P11 is 50 Hz. While this corresponds to AC line frequency in many parts of the world, it is not correct for the U.S., where 60 Hz is the norm. Since PDP-11 Unix was developed in the U.S., the bootable distributions probably assume a 60 Hz clock also. When the software and "hardware" disagree on clock rates, problems happen. My emulated 11 had difficulties keeping accurate time until I discovered the 50 Hz clock rate. After I changed it to 60, the emulator's time was remarkably accurate! If you want to change the default clock rate, you can do so in the source (look for the symbol "clock_rate" in "main.c"), or you can just add set clock_rate 60 into your p11conf file. This will override the default in the emulator program.

That is easily changed though for folks that live in 50Hz areas. Edit the kernel config file and change LINEHZ to 50. The rest of the system has been changed to ask the kernel for the clockrate so there shouldn't be any compiled in assumptions outside the kernel (if I overlooked any let me know and I'll fix it). > My emulated 11 had difficulties keeping accurate time until I discovered > the 50 Hz clock rate.

Earlier versions of P11 would lose time very rapidly if the PDP-11 was "busy" - but the latest version of P11 is fantastic at keeping time. If you run 'ntpd' on the 11 the time stays even closer to "real".

I used it without trouble for years. Recently something broke, and I suspect it trashed my root file system, and I haven't had time to go back and fix it. Since others have the rest running, it's obviously nothing fundamental. Greg -- Finger grog(a)lemis.com for PGP public key See complete headers for address and phone numbers

[pups] Networking With 2.11 BSD and Begemot Emulator

by Frank Wortner

I've been trying to set up an emulated PDP-11 running 2.11 BSD. Just for the fun, I'm trying to get the 11 to talk on a LAN. Unfortunately, it's not working. My configuration is Begemot P11 Version 2.7 running under FreeBSD 4.1.1. I've booted 2.11, configured a custom networking kernel, installed the unix and netnix images, changed the IP addresses in /etc/hosts to match my LAN, run mkhosts to rebuild /etc/hosts.dir and /etc/hosts.pag and rebooted. On the P11 front, I've built a fake qma.rom file populated with zeros -- just like the P11 README file said, made sure that I had a tun driver configured in my FreeBSD system, and started P11. Then I did an ifconfig tun0 host-IP-address emulator-IP-address up Running ifconfig on the host confirmed that things *seemed* to be OK: # ifconfig tun0 tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1518 inet6 fe80::260:8ff:febd:5882%tun0 --> :: prefixlen 64 scopeid 0xb inet host-IP-address --> emulator-IP-address netmask 0xffff0000 Opened by PID 32199 The IP addresses are identical in the first three octets, and differ only in the last octet. Unfortunately, once I boot 2.11 BSD, I can't contact the "outside world" from the emulator, nor contact the emulator from the outside. No telnet, no ftp, pings just hang. Everything looks OK from inside: # ifconfig qe0 qe0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING> inet emulator-IP-address netmask ffff0000 broadcast Bcast-IP What am I missing?

I know the README says this will work, but I haven't been able to get it to work that way. Somewhere I have a real image; I'll see if I can find it.

I have (using BSD/OS 4.1's if_tun which is probably the same as FreeBSD's) an emulated 11 going quite nicely. What you need to do ON THE 11's SIDE, is populate his arp table with the information about any host on the local LAN that the 11 will want to talk to In /etc/netstart on the 11 side just after the 'ifconfig' lines: ifconfig qe0 inet netmask $netmask $hostname broadcast $broadcast up -trailers >/dev/console 2>&1 # ifconfig sl0 inet 192.254.254.2 192.254.254.1 -arp -trailers >/dev/console 2>&1 # slattach /dev/ttyS6 9600 # Next line needed when running under the Begemot emulator arp -s 206.139.202.1 "0:0:c:3d:e9:f7" pub arp -s 206.139.202.51 "0:a0:24:78:9c:21" pub arp -s 206.139.202.200 "0:90:27:88:64:74" pub arp -s 206.139.202.201 "08:0:2b:f:5b:a6" pub arp -s 206.139.202.209 "0:40:5:a4:72:27" pub ifconfig lo0 inet localhost up -trailers >/dev/console 2>&1 Typically you only need the ARP info for the hosting system and the default gateway. Oh, there's a bug in P11 that after 25 days of calendar up time the clock on the 11 basically stops ticking. I've a fix I came up with (and submitted to the author) but it'll be a couple weeks until I know for sure if it's the right fix (32bit overflow in a calculation).

If my memory hasn't failed me that would explain why it worked since 'tap' passes ARP traffic. The missing piece I forgot earlier was on the hosting machine's side to publish an ARP entry for the simulated 11. Just after ifconfig'ing tun0 up use the hosting system's mac address: ifconfig tun0 206.139.202.200 206.139.202.203 up arp -s shemp 0:90:27:88:64:74 pub I'm not sure how ARP can be made to work thru the 'tun' device. Without ARP on an ethernet I am not aware of any 'routing' that can fill in the mac addresses in the ethernet packets. Try pub'ing the arp entries and see if that works. Might try 'tap' instead of 'tun' if you're looking for something else to try. Steven Schultz

[pups] mystery LSI-11 heath H11 board

by Aaron J. Grier

an electrician came in to my place of employment last week and installed some new lighting in the "engineering junkyard" which was previously a very dark place. The new light prompted me to do some exploring, and in doing so, I spotted a heath H11! unfortunately, it looks like the case has been stripped, as only one half-height board remains in the cardcage. The handle is labeled "Heath Serial I/O." I threw it on a flatbed scanner and the pictures are here: http://www.poofygoof.com/~agrier/lsi11f.jpg http://www.poofygoof.com/~agrier/lsi11b.jpg Is this one of heathkit's almost-like-DEC-but-not-quite boards? -- Aaron J.

This can be made to work but it depends on having a program that can transfer the the files "bytes as bytes" (no record format interpretation, etc) _and_ handle multiple blocking factors on the first tape. If you have the PDP-11 volume of the archives you should see in the PDP-11/Distributions/ucb/2.11BSD directory two files called 'maketape.c' and 'maketape.data'. It's a small program and if a counterpart to that could be created for RT-11 you'd be all set to go. The layout of the first tape normally is: mtboot+mtboot+boot (512 byte blocking factor) <tapemark> disklabel (1024 byte blocking factor) <tapemark> mkfs (1024 byte blocking factor) <tapemark> restor (1024 byte blocking factor) <tapemark> icheck (1024 byte blocking factor) <tapemark> root.dump (10240 byte blocking factor) <tapemark> file6.tar (10240 byte blocking factor) <tapemark> file7.tar (10240 byte blocking factor) <tapemark> <tapemark> The 2nd tape contains file8.tar blocked at 10240 bytes. The "boot" tape really only need to have the first few files, up to and including 'root.dump'. Those are enough to boot the tape, run the standalone utilties to label the disk, create the filesystem and restor the root filesystem. The tar archives can be (with suitable interpolation of the installation instructions) be placed on individual tapes. This may be necessary because file7.tar may or may not fit any longer on the first tape. Why three blocking factors? Well, partly historical and partly hardware reasons. The first "file" contains the 'bootblock' and that needs to be 512 bytes since that's all the hardware will read. The standalone i/o system uses 1024 byte blocks so the next few files use 1k records. After the standalone utilities are done and the system is loaded 'tar' can use its default 20 sector (10kb) record size. > 2. A kind soul sends me a set of 9-track 2.11BSD tapes with > boot images. My tape drive may or may not work - it's been ages since it was last powered up and I fear the rubber parts may have disintegrated (or the capacitors dried out, etc). > 3. Other? If you could find a TK70+TQK70 drive+controller that would be awesome. They're pretty cheap (less than $100 I believe - I didn't pay much for mine). Or even a TK50 drive (almost free) attached to a TQK70 would be fine. The TQK70 is a vastly better controller than the TQK50 because the former has a buffer cache that makes a huge difference is how often the tape stops moving. If the Emulex controller you have is SCSI based (UC07 or 08) then someone could stage and make available a 2.11BSD Zip disk image with all the stuff needed to boot and run the installation proceedure (I've a Zip disk attached to my UC08 - works great). Alternatively a 2.11 formatted CDROM could be created and a CDrom drive (that knew about 512 byte blocks instead of 2048 byte blocks) could be used. Good Luck!

Is it in one an Appendix to the "Setup&Installation" document? In the case above it is OV6 (overlays are numbered from 1) that is too big.

Look at the Makefile - you should see a line that starts "OV6=". Do a "size" on the .o files listed for OV6. Pick one that will fix elsewhere - I'd suggest OV5 since it is only 4864 bytes and has lots of room. You could also move a .o file to the BASE since it has adequate room also.

Yep - I have a lead (not too surprising since I wrote the program :)) I think the program's present in the PUPS archive in the top of the 2.11 tree area but it may have been relocated or whatever over time. Here's the program - it should compile on just about anything that has the 'mtio' ioctl functions. It is very similar to 'maketape' (intentional since makesimtape.c started out as a copy of maketape.c).

[pups] Overlays?

by Jorgen Pehrson

Hi, I've just installed 2.11BSD on one of my PDPs, from a TK50 tape I just re-discovered in the trunk of my car. And now I'm in the process of applying patches. When I installed patch 412 and started to rebuild the kernel, ld complains with a "ld: too big for type 431". Does this means that I have to rearrange stuff between the BASE and the various OV entries? How can I find out which overlay is too big? I've tried to do a: 138% root--> size unix.o text data bss dec hex 52352 6928 37622 96902 17a86 total text: 115520 overlays: 7680,7232,7808,7744,4864,8576,4736,6848,7680 How big is too big? And also if none of the overlays above are too big, I guess it must be the BASE that is too big? Is there some sort of documentation anywhere that describe this voodoo stuff and black magic a bit? Btw, I've put my makefile is at http://spektr.eu.org/~jp/Makefile.LOKE. Any suggestions on what .o file I should move to what overlay?

[pups] V7 vs RX50 (was Getting a MicroPDP-11 Running)

by norman＠nose.cs.utoronto.ca

400KB floppies, or even 1.4MB ones, may seem tiny now; but they should hardly be undersized for a bare-bones V7 root file system. Remember that disks weren't all that big in the late 1970s, and that one of the important fixes in V7 was that it became possible to make a file system bigger than 32MB. The V7 version of the `Setting Up UNIX' paper doesn't say just how big the root file system dump is, but the instructions say the file system itself should have 5000 blocks: about 2.4MB. If the dump was that big, it would have taken just over 6 RX50 diskettes. (But it probably wasn't that big, because there must have been a good bit of free space in the standard root--/tmp was there too!) I once ran a stripped-down V7 off a single RK05 (2.5MB including swap) for several days, during an air-conditioning crisis. The system wasn't fully-functional, but there was enough there to let the secretarial staff keep up with their typing, and even run troff. The real trouble with the RX50 is not so much the size as the speed: the damn things are painfully slow. I sometimes boot my V10 MicroVAXes from RX50, as part of an experimental Jumpstart-like installation scheme. The bare-bones installation environment requires only two floppies; the real nuisance is that it takes several minutes to read them. And, of course, V7 doesn't have an MSCP driver, since MSCP didn't hit the streets until 1982 or so. Norman Wilson

It worked fine except that password files were corrupted (and contained unknown passwords) So I replaced /etc/passwd*; /etc/master.passwd; /bin/passwd and /etc/mkpasswd (which was no present) with the files of the RL distribution Now it works very good, on p11 emulator under linux 2.2 with networking support.

Recommending to someone that all they have to do is write a driver when they don't even have a running machine yet is, IMHO, a bit optimistic :-). Of course, under the Mentec PDP-11 hobbyist program he could install RT-11 or RSX-11 or MicroRSTS on such a machine quite nicely from a bunch of RX50 or RX33 floppies he made from the Mentec CD-ROM's. >> 3.)

Hmmm, I don't think they're corrupt. Wasn't there a similar posting a month or two ago about someone (I forget who it was) having "massive corruption". It turned out that the simulator was only told to use 256kb of memory (18bit mode). Once the "set cpu 2048k" command was added to the conf file the problems cleared right up. A good case can be made that it's a bug the system doesn't outright crash if it's unhappy with the amount of memory but given it's so easy to 'add memory' to the system I can't work up any enthusiasm to track down and fix the problem ;) > I wonder if we could prevail upon Steven Schultz (or someone) > to build some 2.11BSD disk images which would be suitable for the > Supnik and Ersatz emulators. Well, one could take the tape images that are in the archive and run the suitable tape preparation program ('makesimtape' for Supnik's simulator and I think makesimtape.c is around in the archive as well). Might need a "toggle in" boot for that (it's in the 2.11 setup and installation guide) though since I do not recall the Supnik simulator knowing how to boot from tape. Try putting "set cpu 2048k" (I don't _think_ you need both "set cpu 22b" and "set cpu 2048k" but having both doesn't hurt and may help).

My questions are: > 1.) What UNIXes have been successfully loaded onto these types of machines? I think we need just one more little piece of information before we can match up a version of Unix with your new machine. We need to know if it's an 11/23 (23+), or an 11/53 (73). The label "MicroPDP-11" was used on a number of systems. If it's a 53 or better then you can run any of the PDP-11 Unix systems that are out there. If it's a 23 class machine then you're limited to V7 or earlier (2.9BSD would probably fit but it would be a struggle and you definitely wouldn't be able to use the networking). Looking at the system maint register with the console ODT would probably be the easiest way to determine the cpu type - examine location 177750 (or 17777750 depending if the system needs the explicit 22 bit address). Bits 4 thru 7 tell the module type: 5 = KDJ-11E (93, 94), 4 = KDJ-11D (53), 3 = KXJ11-C, 2 = KDJ11B (quad high 73), 1 = KDJ-11A (dual high board 73). If it's a 23 the sys maint register probably doesn't exist. Another way would be to look at the module number on the spine of the card ;) > 2.) Can it be done without a tape? If so, has anybody pulled it off? A ~32mb disk is going to be very tight for any 2BSD system. V7 will fit I think. > 3.) Are there any utilities, either DOS or UNIX/Linux/FreeBSD based, to write > and/or format RX50 floppies? Hmmm, I thought John Wilson has some utilities that could do that. Normally you need to buy preformatted RX50 disks or have a DEC Rainbow (DOS) system around.

[pups] AT&T Unix Operating System for Writers Workbench Software?

by Tim Shoppa

In a big batch of 9-tracks and RL01 packs rescued this morning, I have two tapes, one labeled AT&T ** 66938 ** UNIX OPERATING SYSTEM FOR WRITERS WORKBENCH SOFTWARE TPname: LOAD PGM FOR PDP 11/70 the other labeled AT&T ** 66611 ** UNIX OPERATING SYSTEM WRITERS WORKBENCH SOFTWARE TPname: LOAD PGM FOR VAX 11/780 11/750 Both have copyright dates of 1984. You can see scans of the original labels (high-res scans, they're big files!) at http://www.trailing-edge.com/www/wwtapes/ I won't be able to make binary copies of these until this evening, but does anyone know where these tapes fit into the scheme of AT&T stuff? i.e. are these custom-built SYS III and SYS V systems?

It did contain -- as the makefile says -- 'diction' (basically a search for 'bad' phrases), 'style' (which generated readabilty and other statistics for text), 'punct' (a basic punctuation checker), and a handful of other similar programs. Importantly for the PUPS archive, I'm pretty certain that AT&T retained ownership of WWB when it sold UNIX, so it wouldn't be covered by the SCO license. I have no idea who owns it now.

[pups] Pre-startup questions

by W . Suika Roberts

I just (yesterday) aquired a microPDP 11/73 -- it had been used by my school to operate some sort of geological test equipment that is no longer present, and was working when it went out of service, who knows how long ago. She has a pair of RX02s, an RD52a inside her case, and that's all I've determined so far, since I haven't opened her up, really, yet. I'm interested in documentation on monitor commands, what the boot sequence should look like, and other such software stuff right now. I'm also wondering about useful things like: `Is the part number in a standard location on each card', `What is the form factor difference between Q-bus and Unibus', `Will starting her up trip the breaker', and `How much space is there in that little rackmount' In the near future, I'd like to find ethernet and SCSI adaptors for her, and so am wondering where parts might be aquired. Thanks, Suika (very happy) -- ssfr(a)unm.edu The computer is not mightier than a cup of coffee, or other liquid, or a young school age child with a tool box... --L. E.

[pups] 11/23 and other qbus machines

by Tim Bradshaw

I'm maybe going to acquire an 11/23. It looks like this is kind of small for running v7 and/or 2.11 as it has no split I/D (it does have an MMU in it but only an 18-bit one I think). How similar is the physical hardware (card cage I mean really) of this to things like 11/73,11/83? I'm wondering if I might one day be able to acquire a card-set from something bigger and install it in the same rack, my logic being that cards are a lot easier to get from far away than racks, and this machine is only a few miles away.

Yeah, perhaps the best choice here would be the set of RL02's I found with a V6 system on RL02 packs. Hook up a RLV11 or a RLV12, a couple of RL02 drives, and you're in business. >How similar is the physical hardware (card cage I mean really) of this >to things like 11/73,11/83?

It's very similar, but it's also rather likely that the card cage that your 11/23 comes in will only support 18-bit bus addresses. If you want to run 2.11BSD that's not really enough memory. For some details about what Q-bus hardware supports 18-bit stuff and what Q-bus hardware supports 22-bit stuff, please look at your Micronotes, specifically #5, _Q22 Compatible Options_. If you aren't lucky enough to own a set, you can browse them at http://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/microno… In large part, it's impossible to specify a PDP-11 as a "PDP-11/23" and know with any certainty what any single part of it is. There's much more to a system than the CPU (and note there are several very different CPU boards sold as 11/23's), you also have to consider backplane, memory, and disk/tape storage.
