Paul; What disk controller do you have? => 73 KB7LX@K4IWW
Chris; Indeed, and that is the problem. => 73 KB7LX@K4IWW
Bill; I have not seen anything on the new machines but must admit, that the knowledge of their introduction seemed inconsistant with with what has been going on for the last couple of years. => 73 KB7LX@K4IWW
Joe, make that PIP [*,*]*.*/LI.
What version of RSX are running also some things cannot be done in DCL you need to use MCR. The new the RSX the closer the DCL is to a VAX. A good book is VAX DCL. The RSX Files-11 structure is different but basic commands are the same. Unless…

Bill: If you use DSC, then the backup is bootable. The problem is you have to a take down the system to do a backup with DSC. Chris Zach
#PDP 11/23 For Sale
Message #57188
For Sale – PDP 11/23 With 4 RL02 Disk Drives. All in working condition. $300 – You pay freight. Call Paul At 318-989-8525 for details. Thanks Paul
Yes, I understand about DEC pushing people towards VAX, and certain applications where it isn't suited. (Actually I believe the VAX *hardware* is suited perfectly fine… it's just the available operating systems — VMS and ELN alike — which leave something to be desired, but not enough to be desired…
Bill; The software is a proprietary data acquisition system with some site specific design features. The problem with upgrades is that the system is tested extensively prior to installation (at great costs) and generally no one is willing to pay the expense of retesting just to install a new O.S.…
New to TSX
Message #57185
Our company has been running SCO Xenix 2.3.3 for about a year and a half, and we are very tired of it. The recommendation has come to us to change over to TSX-32, which we are planning to do around September, based on what info I can get. I have…
Bill, No, what I'm describing is unlikely to work on RSX 3.2. Lord, that's a decade old now! I'm not sure what you mean when you say that your "experience is that the RSX upgrades are not sufficiently compatible with the older versions to work"… we have never had any…
Chris; Thanks for the additional lessons. I did have a look at there command file and DSC is indeed what they are using. If it is possible to do a backup of DL0: to DL1: that could be restored then the purpose is accomplished. Sitting here musing again though, I…
Bill; Do I understand you correctly to say that what you are proposing will create a backup of DL0: on DL1:? While this is not exactly what they want to do, I suspect that it will serve their purposes even better than what I was hoping could be accomplished. Again,…
Looking to sell scrap.
Message #57180
Hi! This is a sad day indeed. Does anyone know of anybody who buys the gold fingers from DEC M series cards? I am looking to get some cash, and have 2 full pdp-8/I's full of little cards (as well as a RK8 controller, a pc11 paper-tape control, etc). How…
rsx docs
Message #57179
I need RSX docs… v3.2 or above, full set or piecemeal. I will pay any fair price. Please EMAIL response.
P.S.: In addition to information on the display, it would be necessary to know the operating system you're using, since software to make use of the light pen will be operating system specific and the PDP-11 supports a dozen or more different operating systems.
Larry, A light pen is used with a graphic display of some kind. A PDP-11/53 is a general-purpose computer, to which a variety of types of displays can be attached. Most displays attached to PDP-11s in the real world are text-only, and there are no light pens to accompany these.…
#light pen???
Message #57175
Hi Im a new user and would like some help. Does anyone know how I can get a light pen for a pdp11-53? Any info will be appreciated!!!
John, The Rainbow is covered in the DEC PC Forum (GO DECPC). The PDP-11 cannot have a DOS partition; it doesn't run DOS (well… it actually *does* run DOS, but it's a different DOS than the one you're thinking of. One of the original PDP-11 operating systems was called DOS-11,…
#Help
Message #57173
Hi, I am new to this forum and DEC computers. I have just picked up a new client that has a problem. Please help!! The machine is a Digital Rainbow 100. It is on a PDP-11 Network. 1. When we intialized a hard drive on the Rainbow, the maintenance program…
Chris, I forgot to mention: On a same-owner, new-CPU transfer of a layered-product license, a cost-free transfer can only be done if the new CPU is at the same, or a lower, price tier when compared with the previous CPU. This is most significant in the VAX world where there…
Chris, Operating system licenses are transferable to a new owner, with the CPU only; you can't transfer them to a new CPU that you own. Layered product licenses (e.g. BASIC or whatever) are transferable to a new CPU, within your organization only; you can't transfer them to a different owner……
Bill: Speaking of licences, I have a question: If one sells a computer to a company like Midwest (which reformatts all of it's disks), or dumps the CPU , can one have the licence transferred to another CPU of like power? (AKA I dump my 11/45 for a 23+. Can…
Don: Hm. I have a RK07 sitting in my basement. Where do you live? As far as the cables, regular RL01/02 cables should work also. What OS are you running, and what kind of 11 do you have? Chris Zach
Please note that it is NOT legal for one customer to transfer Digital software to another customer, except for operating systems which can be sold along with the CPU on which they are licensed (and some other products like DECnet which are effectively licensed to the machine, not just to…
#RK07 & Basic plus
Message #57166
HELP…I need some cables to hook up two RK07s, I'm too cheap to buy them from DEC!!! I thought that somebody might have some extras in there "junk" box (grin). Also I need a copy of b [A [Asorry about that… I also need a copy of basic plus, I…
David: Ah times do change. For a long while, I was working off RL01's. (Then my life changed with a pair of RM02's…) Chris
Bill: It would probably be easier to use DSC. Unfortunately, you would have to take the system down for the copy operation (both disks have to be unmounted). The problem with copying, is that RSX maintains a boot file and STB entry for all of the files that start the…
#RL02 drive for sale
Message #57161
I have an RL02 drive and about 30 packs for sale for B.O. I realize these are sort of in the boat anchor category, but if you could use them, contact me. I'm sure we can work something out!
I have the micro rsx system. Thanks for the tip i will try it out. I have a lot to learn about the system and a very short time to do it. After all i cannot drop the system off line after its in its new home. J
The command to look at files on the disk is, simply, DIR. Directories are referenced in brackets, e.g. DIR [MUMBLE] gives you a list of the files in the directory called [MUMBLE]. RSX supports only a single-level directory structure. There are several variants of RSX around; the three most common…
LSI 11 Battery Backup
Message #57156
Terry… I saw messages about hooking up a battery to the LSI/11, and I happen to have a DEC microcomputer processor handbook, circa 1978, that has some info which may be of use to you. Backplane pin AS1 is +12v Battery Power Backplane pin AV1 is +5v Battery Power Only…
XINU on LSI/11's
Message #57155
I just completed an Operating Systems design course, where we used the XINU O/S on a microvax-LSI/11 setup. (Textbook by Douglas Comer.) I would like to hear from others who have had experience with this environment. I'm a programmer with experience in DEC, PRIME, IBM (MVS,VM,DOS/VSE,PC-DOS,etc), and now…….XINU.
#RSX 11 help
Message #57154
Hello and Help! In my regular job i work as a 2 way radio tech. However due to my computer hobby and such as the world of computers has now integrated with 2 way radio systems i get to be system admin of ever more computer systems. My lateest is…
I just have had a pdp-11/73 dropped into my lap and now i am the system admin. This is a brand new 11. j
There *is* a way to backup disk-to-disk that is known to work, but it does not produce an image, bootable, target disk. You can use the /IMAGE:SAVE and /SAVE:savesetname switches on the BACKUP command, and it will produce a saveset on the target disk, rather akin to what VMS does.…
Bill; I am virtually certain that you are right about the checkpoint file. The system this is about is a distributed processing system (the 11/34 is the host). There is extensive use made of the checkpoint file but the system restarts following powerfail almost always without a hitch. I suspect…
Chris; Thanks for the reply. I am afraid that I am probably just displaying my ignorance of the RSX disk structure, but I would think that PIP would not accomplish the task as the resulting disk must be bootable. However, the DSC idea looks promising or maybe BRU. Unfortunately, I…
I think there's a /IM(age) switch to PIP, or something like that, which should do the job. Of course your concerns about open files on DL0 are perfectly valid. There is no guarantee that the target disk will be logically consistent if you do it this way. I don't think…
Bill: The only thing I can think of is either DSC/BRU, or writing a little command file to look at the directories on the source drive, make the dirs on the target drive, and then do a copy src:[*,*]*.*;* dst:[*,*]*.*;*. This would not copy the checkpoint file, since that is…

#PDP HANDBOOK & THANKS
Message #57137
HELLO Thanks for the info, we appreciate it. We were wondering if there is a way to trace a bus hang on a pdp. We tried the "remove a card and try it " method and also tried to use a "minimal system" as described in the minimal documention we…
#Copy Device?
Message #57136
Does anyone out there in PDP11 land know right off hand if there is an RSX-11M command that is equivalent to the RT11 "copy device" command? In particular, I want to copy DL0: to DL1: while the system is running an application…… of course as I think about the problem,…
I think the "modem" designation actually refers to the "line driver" portion of the DMP-11… the part that talks to the cable between the machines. -Bill
As Bill replied, the boards constitute a DMP-11 communications interface. The DMP-11 implements DECs DDCMP point to point method of allowing 2 or more computers to talk amongst themselves. It is capable of 56kb to 500kb in full duplex mode or 1mb in half duplex. One DMP11 can control as…
The M8203/8207 is a DMP11, which is a high-speed inter-processor communications link (synchronous). It was a relatively obscure device and I can't put my finger on any specs right at the moment, but I'd bet it runs much faster than 9600bps, probably 56Kbps, perhaps even 1-1.5Mbps. Note that V.35 has…
#PDP INTERNAL MODEMS

HELLO We are in the process of building a BBS using one of several PDP's (an 11/23 (MINC) , an 11/34a, and a 11/44) and we found a board in the 34 marked MODEM V.35. Of course, we have no documentation on it and wondered if anyone new if it…
Smart Multiplexers
