Problems Booting RSX-11M V4.4 on a PDP-11/24 from an RA80 Disk Drive

by NOcmcnabbSPAM＠4mcnabb.net

I've finally got what I think is a good sysgen for my PDP-11, but I'm having a hard time getting it to boot from an RA80. Here is the machine config: PDP-11/24 Unibus Map Memory Map Floating Point Unit Extended Instruction Set DZ11 Async board 512 KW (1024 KB) Ram Two RL02 Disk Drives One RA80 Disk Drive with MSCP controller Here is the sequence of commands I am using to transfer the system from the RL02 (where it was sysgened) to the RA80: >MOU DU0:/FOR >ACS DL0:/BLKS=0 >INS $BRU >INS $VMR >INS $PIP >DMO DL0:/DEV >MOU DL0:/FOR >BRU DL0: DU0: (BRU Initializes DU0) >DMO DU0: >DMO DL0:/DEV >MOU DL0:RSXM46 >MOU DU0:RSXM46 >SET /UIC=[1,54] >PIP DU0:RSX11M.SYS/NV/CO/BL:2050=RSX11M.TSK >ASN DU0: SY: >ASN DU0: LB: >VMR @SYSVMR >BOO DU0:RSX11M.SYS XDT> G RSX11M V4.4 BL 46 > TIM XX:XX XX-XXX-XX Note: A 'DEV' command at this point shows all the proper devices and redirects. > SAV /WB /MOU="DU0:RSXM46" The RA80 Ready light flickers for a few seconds, then the channel select light will go off and back on twice. Then the system hangs. If I boot from the RL02 at this point, and then try to boot from the RA80, the system will hang again. Booting from the ODT prompt (173204g) yields the same result. The system hangs wether or not I specify the /MOU option to the 'SAV' command. If I try the boot right after the BRU command, I get the expected "Device does not contain a hardware boot block' message, so I know the MSCP controller is working. I don't know why I can boot the first time with the 'BOO' command, but not subsequently. Anyone out there have any clues?

I'm not sure what LINK does, and what input it needs. It's a long time since I used MACRO-11, but I'd have expected it to generate the "correct" values, for a start. What Pat's output showed was: 7 001000 012767 000110 177566' MOV #110,XBUF but if you were entering that in ODT, what you'd want would be 7 001000 012767 000110 176552' MOV #110,XBUF In other words, you'd want MACRO to do the calculation for you, and have LINK adjust that if the eventual loading address was other than 001000. If I were redesigning MACRO from scratch, I'd have it mark the PC-relative addresses more obviously, perhaps something like this: 7 001000 012767 000110 [176552] MOV #110,XBUF but then it would be more reasonable to put the target address, 177566, in the listing, rather than the offset, 176552. Maybe it could do both, but it gets a bit clumsy: 7 001000 012767 000110 [177566] (+176552) MOV #110,XBUF This is just for the listing, obviously; what it puts in the .OBJ file would not change. However, I imagine any such changes would bring howls of protest from generations of MACRO programmers :-) > I tried the real MACRO (under RSX-11M) and it adds an apostrophe to the > initial setting of . (which is what I'd expect, since . was never given > a numeric value, only incremented from its default) but still no apostrophes > after the addresses later in the listing. I don't have any listing readily to hand. Were the addresses shown as the target addresses, or the offsets required to reach those tagets? -- Pete Peter Turnbull Network Manager University of York

Free HP 5332A Preset Controller/Counter

Not sure quite what it does -- I just pulled it out of a dumpster in the Loop that has a ton (literally) of old video production equipment in it. Don't know if it works, even. Has a nice 5 digit nixie display. Sticker on the back says it was last calibrated in April of 1976. Anyway, free for postage (about 10 pounds shipping weight, from Chicago). If more than one person wants it, I'll draw slips from a hat, tomorrow at noon (CST). Reply directly to me at robert_feldman(a)jdedwards.com. Bob

Bring up CPM-8000, I need a little CPM type help

by dwightk.elvey＠amd.com

Hi I've been working on bringing up a CPM-8000 on my Olivetti M20. I've made quite a bit of progress but I seem to have hit a stumbling block. The code that was available on the net was found on 8 inch disk. The files themselves seem to be the correct code to run on 5-1/4 inch disk. I've been building a image disk on my PC and trying them out on the M20. I've got to the point now ( after some other failed attempts ) that it is running the bootstrap code. This is the last part before it reads CPM.SYS and transfers execution to it. The bootstrap code expects there to be a file called CPM.SYS in the normal CPM file space and looks in the CPM directory for it. Right now, I get an error message that says it has an error opening or reading CPM.SYS ( this is how I know the bootstrap is running ). Looking at the source code for this part, it doesn't make the distinction between an error in reading the directory or an error in reading/finding the file. I suspect that I am either building the directory wrong or I got something wrong with the file. I'm not sure which it is. I feel I am really close to getting it to work but there is some little thing I missed. I what hoping is that someone could look at my image file and see something obviously wrong or could send me an image of a normal 5-1/4 CPM disk ( hopefully with the same parameters ). You don't have to know any Z8000. You do have to know the inners of CPM. Thanks Dwight

Bring up CPM-8000

by dwightk.elvey＠amd.com

Hi Since there was a bunch of CPM-8000 stuff showing up lately, I've been trying to get it to work on my Olivetti M20 ( what the release code is to run on ). The code I got was originally from 8 inch disk. I have both the 8 inch disk images and the files recovered >from the disk. The 8 inch disk were not boot disk but contained enough information to build a boot disk. As near as I can tell, the code was to run on a 5-1/4 inch disk and not the 8 inch. That is what I have been working on but I've reached a stumbling block. It seems to be CPM related so people that know CPM should be the most help ( I mean, know what directory structures should look like and how the disk blocks are referenced, not just, I can use PIP or ED ). I've been building a boot image from the files and what I understand of how CPM should look. I've got it to the point that it runs the low level bootstrap code but fails to do the final load of CPM.SYS. I know it is running the bootstrap because it prints the error message that it has an error in opening or reading CPM.SYS. This is only in the bootstrap code. I have the files on my PC and I've written some code to build the image. I then copy the image to a disk for my M20 and try to boot it. So far it doesn't seem to get the CPM.SYS file correctly. I can't tell if it is an issue with the directory I built, the file location or something about the file itself. I hope one of you can help me by looking at my image file and confirming that I am building the directory and file correctly, for a CPM type file. Thanks Dwight

Well, addressing mode 6 and 7 aren't meant merely to generate relocatable code -- given suitable information, any linker can relocate code. Mode 6 and Mode 7 generate position-independant code (PIC), code that can be moved at any time without alteration. The PDP-11 was designed to make that easy. On Sep 17, 4:26, Derek Peschel wrote: > Pete, I replied to your other post in this thread. I'm just trying to > understand what "the right thing to do" is here. Well, I'd say the "right thing to do" is to use absolute addressing modes. What modes 6/7 do is generate references which are relative to the instruction address. They're meant for things that will move if the code is moved (eg the target of a JSR). However, the address of a device register doesn't move, so although it's possible to refer to using modes 6/7, it breaks the position-independance of the code. If you move the code, you need to recalculate the address offset. Once assembled, the first part of Pat's code, despite using mode 6, is not PIC: 4 177564 XSR=177564 5 177566 XBUF=177566 6 7 001000 012767 000110 177566' MOV #110,XBUF 8 001006 105767 177564' L1: TSTB XSR 9 001012 100375 BPL L1 10 001014 012767 000064 177566' MOV #64,XBUF 11 001022 105767 177564' L2: TSTB XSR 12 001026 100375 BPL L2 13 001030 012767 000130 177566' MOV #130,XBUF The actual values in the finally-assembled code would be (if I've done my arithmetic correctly): 7 001000 012767 000110 176552 MOV #110,XBUF 8 001006 105767 176550 L1: TSTB XSR 9 001012 100375 BPL L1 10 001014 012767 000064 176536 MOV #64,XBUF 11 001022 105767 176534 L2: TSTB XSR 12 001026 100375 BPL L2 13 001030 012767 000130 17652 2 MOV #130,XBUF Note that the pointers to XSR and XBUF change according to their position in the code, because they're PC-relative (even if my PC-relative arithmetic is wrong, the differences are correct). Now if he'd written it using absolute addresses: 7 001000 012737 000110 177566 MOV #110,@#XBUF 8 001006 105737 177564 L1: TSTB @#XSR 9 001012 100375 BPL L1 10 001014 012737 000064 177566 MOV #64,@#XBUF 11 001022 105737 177564 L2: TSTB @#XSR 12 001026 100335 BPL L2 13 001030 012737 000130 177566 MOV #130,@#XBUF ... they don't change. Moreover, since there are no JMPs or JSRs, only (relative) BRanches, this is PIC. Now if he wanted to write it using a subroutine, and he used the simple method: 7 001000 012701 000110 MOV #'H', R1 8 001006 004537 JSR R5, @#PUT 9 001012 012701 000064 MOV #'4', R1 10 001014 004537 JSR R5, @#PUT 11 001022 012701 000130 MOV #'X', R1 12 001026 004537 JSR R5, @#PUT : : 35 001100 105767 177564 PUT: TSTB @#XSR 36 001104 100375 BPL PUT 37 001106 010137 177566 MOV R1, @#XBUF 38 001112 000205 RTS R5 That's hand-assembled, in a hurry, so don't rely on the opcodes being correct! but the point is that the subroutine is referred to by its absolute address, so the first part of the code can be moved but not the subroutine (because its address is fixed). However, if it were written using relative addressing, ie 8 001006 004567 JSR R5, PUT : 35 001100 105767 177564 PUT: TSTB @#XSR then the whole thing can be placed anywhere in memory without alteration (so long as the subroutine stays in the same position relative to the rest). Of course, the subroutine still uses absoute addresses for the registers. Does that make it clear what the point of the two types of addressing is? My example is a bit contrived; that's not really how I'd do it. Instead, I'd write a subroutine that wrote out a whole string, the string being stored immediately after the JSR, and returning to the word after the string. But that's another story. -- Pete Peter Turnbull Network Manager University of York

Fwd: 68 Micro Journal

by tlindner＠ix.netcom.com

Here is a message that came over the Flex Users Group mailing list recently. Though you all might be interested. Cross posted with permission. ------- Begin Forwarded Message ------- Subject: 68 Micro Journal From: Mickey Ferguson <mickey_wa4kdc(a)yahoo.com> To: Multiple recipients of fufulist <fufulist(a)X.net> Date: Sat, 31 Aug 2002 10:38:25 -0700 (PDT) For a couple of old retired guys, Ron Anderson & I have been busy! :) Back in the spring I made a trip up to Chattanooga & spent the better part of a day with Larry Williams. We discussed everything under the sun, but mostly 68 Micro. I told him that Ron & I were planning on scanning 68 Micro and putting it on CD-R for our own use & maybe sell a few sets to recover our costs [tho not our time. You can't imagine the hundreds of hours we have invested!] Larry & Tom are all for the idea but technically cannot give permission for several reasons, mostly because Don left 68MJ equally to all 5 of his children. And like any family of that size, they can't agree on what day of the week it is! :) Larry has discussed this with his attorney and is of the opinion it is covered by the "fair use" clause of the copyright law. His only stipulation was that he get a copy of the original scans, plus a copy of the distribution disks for himself and each of his siblings. [Believe it or not, but that is 105 CD's!] At any rate, we've finished! Each page of the magazine is a 1024 pixel width JPG file that is easier to read than the pages we started with! I did the scanning and Ron did the adjusting. He did a masterful job! He thinks I had the hard job, but I think he did! You wouldn't believe the differance in the before & after images! Ron has written a viewer program especially for viewing 68MJ files. It runs under Win9x or ME [I'm not sure about XP.] If you are running Linux [or Windoze for that matter] Compupic available from photodex.com also does an excellent job. Ron's viewer program is included on the CD's. This is a 5 CD set and is the complete 68 Micro. Every page from the first issue thru the last all 8105 pages. If you want a copy, you can order it from either Ron or me. But I would suggest ordering from me unless you want to wait til October to order because Ron is about to depart on an extended vacation. We are asking $25 for the set including postage. If you are outside the U.S.A., better make that $30 if you want air mail instead of slow boat! If you want a set send a check, money order, or even cash [as Yogi Berra said "that's almost like money"] to: Mickey Ferguson P.O. Box 520 Wausau FL 32463-0520 or Ron Anderson 1107 Citation Circle Hendersonville NC 28739 NOTE: U.S. Funds only, please.

I'd like to modify that. I found a specific page that defines it as 18 guage stranded (S) vacuum cleaner (V) cord with plastic outsides (T).

DG AViiON NVRAM backup procedure available

by red＠bears.org

Howdy. For those of you I've been speaking with about Data General AViiON NVRAM backups, I've written a procedure and published it on the web. For those of you with AViiONs whom I have NOT yet spoken to, please check the page out and consider sending me backups. I'm in the middle of dissasembling the NVRAM contents so those with failed NVRAMs can restore their systems, and I'm in need of additional data points to complete my research. http://www.bears.org/~red/museum/aviion-nvram.html Thanks for your support. ok r.

I didn't mean to denigrate your code :-) I guessed you might just be learing about MACRO-11 and the PDP-11 instruction set. I learned by writing short toggle-in programs, mostly hand-assembled, mostly to test hardware, and some of them are much more embarrassing than your effort :-) Yes, it is fun, and I offered the examples purely in the spirit of contrasting two types of addressing modes, whose syntax isn't always immediately obvious to a beginner. Now you can write subroutines, have you tried a little fun with co-routines? -- Pete Peter Turnbull Network Manager University of York

New acquisition

by pat＠purdueriots.com

I've just picked up a nearly-free NCR model 2119 (class 3400-MSTD). It appears to be almost exactly the same (probably somewhat newer version) as the Unisys U5000 I once had. Of course, there's no information available on the web, and it didn't come with any documentation. However, I do still have the old Unisys manuals for the moment so I can figure out what is what (Will: email me if you still want those, I've not heard back from you in a while). I've got to get the thing cleaned off outside, and then moved upstairs... that will be not-so-fun. It's about 30"x30"x8" deep (guestimate dimensions) and weighs in excess of 100LBS. It has a pair of MFM hard drives (full height 5.25") a streaming tape drive, and a 5.25" floppy drive mounted in it. Also has 8 RS-232 DA-15 serial ports, a parallel (?) printer port, and some sort of other, possibly serial, DB-25 port. I'm hoping that it still has an OS on it, I might be able to figure out how to get around and root password it has... Anyone have more info on the system? I'm gonna get some picture up as soon as I can drag it up here. -- Pat

Emulex QD32

by P.Gebhardt＠gmx.de

Hi all, I'm ready to attach the controller to the backplane of my PDP 11/23 but before, it would be interesting to set the jumpers correctly. On the net, I just found jumper descriptions of the QD33, but the jumpers are different. Is there anybody who can tell me how to set the jumpers ? Moreover, the descriptions on the net are a bit confusing. Several sites say that the QD32 is an E-SMD controller, while other sites talk of a SMD-Controller ? So which interface does this controller support ? And the last thing: 3 big FSD-500 (CDC) drives (9") are waiting to be connected. I hope that the QD32 supports E-SMD as I read that these drives are E-SMD drives... Same case as to the controller... I can't find any descriptions or manuals on the net in order to set the jumpers correctly. Seagate bought CDC at the beginning of the '90 but they didn't answer me. Thanks alot for any help !

Available: IBM 3833 Modem

by wh.sudbrink＠verizon.net

I recently acquired this through my network of friends who know I collect "old computer stuff". It's a 2400bps 4-wire leased line modem. Seems to have been manufactured in 1984. It has a nice case and power supply, that I'll use for other projects if no one wants it or can make a case for its preservation. I also have the "Maintenance Information and Parts Catalog" (First Edition) and a customer troubleshooting guide. I seem to recall that there are a couple of modem collectors on the list.

International Modems?

by seeker2k02＠yahoo.com

Does anyone know when the first international-capable modems were sold? I know that there were Hayes commands pretty early on that allowed modems to be configured for either US or Europe, but I suspect this may have been more related to signal standards than to phone line requirements (such as impedance). I'm looking for a modem that could be switched between US, Europe, and/or Japan phone lines. Can anyone help? Thanks. Laurie --------------------------------- Do you Yahoo!? Yahoo!

>Did Kodak own Firey? I always thought they were their own company. Good question. I have only seen 3 Firey boxes ever (and personally used none). All 3 had big Kodak labels on them, so I just kind of assumed it was a Kodak product. That could of course be a bad assumption. Based on the big labels concept, most of my WinTel PCs must be made by apple, because they all have big apple stickers on them (as well as my old car) All 3 of the ones I looked at were fat square mini-tower size boxes, two were beige, one was black, and I have NO idea what was in them (my "looking" at them was pretty much just that, they were on the floor near a color printer, I pointed my eyes at it, and looked) -chris <http://www.mythtech.net>

>They had some >wierd Kodak computer, looked like a Sun pedestal and might have been an >OEMed Sun 3 or 4. It might be a Kodak Firey (sp?). It was their print RIP for their high end printing system. I'm not sure what a Sun pedestal looks like, but the Firey that my Uncle's store had looked like a fat boxy PC mini tower. It connected via Ethernet IIRC to their Mac, and then connected to a Kodak printer/color copier unit (might have been an Agfa or Canon printer/copier, not sure). I could see one of these coming out of a school's graphic arts department. I'm not sure how much these are used any more now that many of the workgroup color laser printers give as good or better quality than the early color copier/firey sytems, and at a much lower cost. Or, it might be a newer Kodak photo processor that you find in those one hour photo places, although I don't know why a school would have one of those and be ditching it (I was under the impression they weren't owned by stores, but rather leased as part of the kiosk and had to be returned to Kodak when they were no longer wanted) -chris <http://www.mythtech.net>

New Toy! SWTPC 6800

by rigdonj＠cfl.rr.com

I found a new toy at the hamfest this past weekend. A SWTPC 6800 computer and an AC-30 Cassette Interface. Can anyone asnswer some questions about these? This one has MP-A CPU card, a BOAZ D64kb memory card, a Percom LFD-400B Mini-Disk Controller, a MP-S (serial interface?) card and a MP-L (parallel interface?) card. The MP-L card has a small board hanging off of it with a Datel D/A converter IC on it. Does anyone have any suggestions about whewre to start with this? (After I check the power supply, etc) Does anyone have the terminal connections for this thing? Also the pin out for the Percom Disk controller and info about what drives it supports? and what disks format and wheather they're hard or soft sectored? Joe

SE/30 odd behavior

Ouch, I really hope that this is not the case; SE30's are rare here in Colombia. I know that I haven't plugged an external floppy to this machine in eons. So if it is fried, that came out of the blue. I did another experiment: I unplugged the floppy ribbon cable and turned the computer on. No more "...initialize or eject" dialogs. I've been looking at the SE30 schematics (http://www.archaic-apples.com/index.php?category=Macintosh&subcategory=Sche matics), especially page 2 of the SCSI-SWIM diagrams, where the floppy disk controller is depicted. I see that the RDDATA line in the header is tied to the RDDATA _and_ SENSE pins in the controller chip. I don't see any signal name other than "SENSE" that might indicate if there is media in the drive. I also see that all of the lines go through an "RCNET" pack before heading out to the external floppy disk connector. I wonder if the problem might be in this device... I'd like to wait for input from you guys before I turn on the soldering iron. >I suppose it goes without saying that the floppy controller is not a >standard part. Not socketed, either :-( . carlos. -------------------------------------------------------------- Carlos E. Murillo-Sanchez carlos_murillo(a)nospammers.ieee.org
