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). I see on closer looks, they are refering to the cable used. The only mention of the connector type is in one place, they call it a PH-163 which I think is a NEMA number.

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

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.

Printronix P300 Free for pickup (broken)

by mythtech＠mac.com

I have a Printronix P300 printer here in New Jersey that anyone that wants to come pick it up, can have it free. The printer does NOT work to the best of my knowledge. Many years ago we had the 3 phase power coming into the building short across the building power, and it toasted the power supplies to most of the equipment here. This printer was one of the items that died. We had someone in to look at it, and IIRC, they said the transformer was shot and would need to be replaced. They wanted $400 for the job, we didn't want to pay it, so we swapped the printer for a Citizen's dot matrix. I kept the Printronix with the intent of one day fixing it myself, but years later, we no longer have the system it went with (a Zebra and later PCs running PICK OS), so I no longer care about fixing it. I have the printer, a paper basket, and the "Applications Manual" (looks like a normal user manual). I thought I had some extra ribbons for it, but I don't see them (if I find them, then I will include them). The printer is mounted on a rolling stand (I thought that was the only way they came, but the manual pictures it without the stand). It uses wide carriage tractor feed paper. The printer is rated as a 300 LPM (that's Lines Per Minute, so it is WAY faster than your standard 300 Characters Per Minute dot matrix printer). The connector on the back is a Centronics looking connector, and the manual says it is a Parallel printer, but I could have sworn it was connected to a port on the Digi-Board, which would have made it a serial printer. I'm probably remembering wrong as to how it was connected, and it probably is a parallel interface, but I can't say for 100% sure. (I know its replacement was a parallel printer) This thing is large, and heavy, so shipping is out of the question. If anyone wants it, they can come pick it up. I can hold on to it for a while, so it doesn't have to be an ASAP pickup (heck, I've been storing it now for about 8 years, what's another few months or so). I can post a picture if any one is interested. -chris <http://www.mythtech.net>

Weekly finds

by jbmcb＠hotmail.com

Went to the U of M property office for my bi-weekly Classic Computing collecting endeavour. Picked up a few wierd video and SCSI cables, and an Intel ProShare video conferencing system (Cool camera!) Also an HP 900/something terminal and Centris 650 for parts (Had a cool NI ADC board, too) They had a CDC 9-disc array, looks to be eighties vintage, in a beautiful blue steel-and-aluminum rack. Also had the matching disk pack drive, standard 19" width and REALLY deep. They had some wierd Kodak computer, looked like a Sun pedestal and might have been an OEMed Sun 3 or 4. An HP 16-Track reel-to-reel data recorder for $50, a steal, as it seemed to work fine except for a few burned-out bulbs on the light-up buttons. They still have the big RS/6000 disc arrays and tape backup units, if anyone has a few thou to blow and a semi to pick them up with. Good luck hunting! _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx

I'd argue that it *is* incorrect, or at the very least, bad practice. Relative addresses are meant for situations where the target is a label, indicating something which must move if the code does, like the target of a JSR, or a block of data attached to the code; if you mean to indicate something like a memory-mapped register, which has an absolute and invariant address, you should use absolute addressing. Given that Pat said he was going to enter the code using ODT, I imagine he expected the MACRO output to be the correct numbers to enter. But he used the wrong addressing mode to do that :-) > My personal opinion is that the MACRO-11 program should make the > situation plain, but unfortunately I suspect that MACRO-11 will never > be modified by the present owners. I suspect you're right :-) Besides, the output is meant for the linker, not ODT, and I'm not sure how you could make it really plain that the numerical value in the output is not what the linker will turn it into, without a lot of (usually) unneccessary clutter. -- Pete Peter Turnbull Network Manager University of York

Note that I also output ONLY a byte. Pat is using PC-relative addressing -- probably inadvertantly. The 67 in that opcode 012767 means mode 6, PC-relative, so the address actually used is the address of the instruction word, plus 4 (for the increment of the PC), plus the value given. It's like an indexed address, but using the PC as the index register, and it'll be 1010 bytes off. As Jerome points out, the correct way is to specify an absolute address, address mode 3, by typing @#XBUF instead of just XBUF. -- Pete Peter Turnbull Network Manager University of York

MACRO-11 help

by pat＠purdueriots.com

I'm trying to get some assembly code to run on my 11/23 by entering it in at the ODT, and it seems like I'm having trouble with device I/O addresses. All I've got in the machine right now is the CPU card, an M8044 with 32kW at address 0, and the DLV-11J, set up so that port 3 works with ODT as a console port. I've got a DLV11-J set up so that port 3 is the console, and I can interact with ODT just fine. However, when I try entering something that should read or write to the console, nothing happens. Below is a listing of the assembled code I'm trying - I got the I/O address out of a PDP-11 assembly programming book I got from the library. Most likely the book was written with a UNIBUS -11 in mind, not a QBUS one... is that a problem? 1 000000 LC=. 2 001000 .=LC+1000 3 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 14 001036 105767 177564' L3: TSTB XSR 15 001042 100375 BPL L3 16 001044 012767 000060 177566' MOV #60,XBUF 17 001052 105767 177564' L4: TSTB XSR 18 001056 100375 BPL L4 19 001060 012767 000122 177566' MOV #122,XBUF 20 001066 105767 177564' L5: TSTB XSR 21 001072 100375 BPL L5 22 001074 000005 RESET 23 001076 000000 HALT -- Pat

Years ago, I made two (different) "distribution boards" so I could use my RQDX1 and RQDX3 on machines that didn't have the proper DEC board. One was no more than a small (2" x 4") perfboard with a 50-way connector for the cable to the RQDX1, a 34-way header for the RX50, and another 34-way, with adjacent 20-way headers, for one or two RDxx drives (actually I used either a Rodime or a Seagate). It also had a terminator pack (7-resistor SIL pack) and a set of jumper pins to take the place of the panel pushbuttons. The interconnections were just hand-soldered, using wire-wrap wire. However, I also made a PCB which does the job more neatly, and which I mounted inside an old TK50Z box (is that a "leprechaun box"?), along with the original PSU, an RX50 (where the TK50 used to be) and a Rodime 10MB drive. It's still in use today (literally today, as I'm using it to copy some RT-11 stuff for someone). I've put the document I wrote (in PostScript format) listing the RQDX distribution board connections and signals, along with some notes about using random floppy drives, on my web site. It's not just a list of signals and pin numbers; it also describes what they actually do. I've also put the layout for the distribution board PCB up there. http://www.dunnington.u-net.com/public/RQDX/ I once traced out the connections and drew the circuit diagram of a real M9058 distribution board (which is what my PCB emulates) but I can't find the document. Sorry! However, I do remember that it's very simple. > 1b) What DIP switch settings should I use on the RQDX1? Well, that's easy, because it has no switches :-) If you mean the jumpers, they're set as follows: There's a group of jumpers to set the starting LUN (Logical Unit Number) of the RQDX1, at the back edge on the right (top left if you're looking at a board from above, with the contact fingers downwards and the LEDs and connector at the top). The jumper positions are labelled 0 to 7, and represent powers of two, so no jumpers at all sets "0", a jumper on the first position ('0') sets "1", a jumper on the second and third positions sets "6", etc. If this is the first or only MSCP disk controller in the system, set LUN 0 (which means it controls drive units 0-3, ie four LUNs starting at 0) ie remove all the jumpers. Another set of jumpers, near the "Row B" contact fingers, sets the addresses of the IP and SA registers, by setting A2...A12. The A2 jumper position is nearest the "Row A" fingers and the A12 position is near the "Row C" fingers. Jumper IN is a '1', no jumper is a '0'. A0 and A1 are always zero, and the higher bits are controlled by BBS7 so there are no jumpers for those bits. The standard address is 17772150, set by jumpering A3, A5, A6, A10, A12. The interrupt vector is set by software as part of the bootstrap; it's usually 154 for the first MSCP device. Finally, there are four wire links, W1/W2 near the "Row C" fingers and W3/W4 near the centre of the board. Actually, they're usually zero-ohm resistors. W1 and W2 are for grant continuity, they are IN for use in Q/Q or Q22/Q22 (serpentine) backplanes and OUT (removed) for use in Q/CD or Q22/C (straight) backplanes. I don't know what W3 and W4 do, but they're IN on mine. > 1c) Does someone have a bootstrap I can enter using ODT to boot RT-11 off > of an RX50 or the hard drive on the RQDX1? That's harder. The way MSCP works, by setting up message blocks and passing them to the controller, makes it a bit complicated, and I've never seen a stand-alone bootstrap. The easiest way might be to get the boot code off an Emulex controller to disassemble, as at least that wouldn't have all the overhead of dialogs and options for other devices which the DEC boot ROMs have. -- Pete Peter Turnbull Network Manager University of York

It may be easy but one can never tell. I'm not much of a C expert. I wish they'd just done it in assembly. Proper used of macros would have made the job easy enough. My main complaint is that it requires either a PDP-11 with their compiler or a working CP/M-8000. Of course, that is what I'm trying to create. Writing an assembler is relatively trivial while writing a C compiler is a bit more. There are several M*** assemblers that one could easily adapt to the 8000 out there as well ( I do tend to write my own though ). The stuff from the web site looks like one may be able to build a booting disk. I'll be working on that, over the next few days. Dwight

CP/M-8000

by dwightk.elvey＠amd.com

Hi Chris I spent quite a bit of time looking at the stuff from the web site on the CPM-8000. It looks like the CPM.SYS in the cpm8k11 stuff is built specifically for the M20. It was made with the symbol table so I was able to find the various tables. I don't think the fellow that did this implementation really had a solid grasp of a boot process but what they have done should work. There is no reason why what they call CPMLDR.SYS couldn't have been a slightly modified CPM.SYS with a simple loader added ( like more traditional CPM's ). If you look, you'll see that in one place ( I forget where ), they have a compiler flag called TRANSFER. It would seem that they had, in fact, connected a 8 inch drive to a system as the next drive after the hard drive. They used this as a transfer system. The disk, that the .img files were from, was built as though it were for this setup. It was not a bootable disk. There is quite a bit of information on building a boot disk in the various files that contain the tables T0S0, T1S0 and T1S1. These are the main information involved in creating a boot disk. My understanding of T0S0 leads me to think that the one they have is not correct but may have still worked. I believe we can continue to just use the unaltered T0S0 that is on the disk, formatted by the M20. We can just build the bootable image on one of these disk. We don't need to get too carried away. Once we've built a disk that boots, we can add one file at a time to a different disk and transfer them using the second drive. This way, we only have to deal with the directory on the CPM for one file at a time. This simplifies transfers but may take a little extra time. Still, we wouldn't have to deal all that much with disk space allocation. I'm going to fiddle with trying to build up an image but I'll only be able to do this in the evenings this week. Next weekend I'll be off visiting relatives. I converted another RAM board to 128K. It now boots to 384K :) It was one of the two B/W memory boards that I have. It wasn't as simple as I thought. Changing pin 8 >from +12V to +5V was just a simple jumper change but Pin 9 had connections inside to an internal power plane. This time, rather than lifting a pin on the chips, I lifted one of the socket pins. I used a little quick setting epoxy to insulate the board pin 9 from the socket pin that I bent out to the side. On these boards, there was at least, a nice jumper hole to connect this additional wire to ( it even looks like they had intended it to be jumper configured but the internal plane connections kept one from doing that ). It took me about 4 hours to do one board. I could have done it faster if I didn't want to save the IC's. Just clipping the IC out and pulling the pins is a lot faster than removing the entire IC, intact. It is a lot safer for the board but I just can destroy working chips. Anyway, do you know of any issues that I should look out for in creating a boot disk from these files? I haven't seen anything that looks like a show stopper. Dwight

This weekend I wnet to the Melbourne Hamfest and stumbled across an old programmer that is supposed to burn Harris 7611's. Now If I can just get Bob to send some of those chips back to me, maybe I can make dups.

Need power plug

by MTPro＠aol.com

Would anyone have an extra power plug they could sell me for my generic S-100 computer? Somehow mine must have gotten given away with other misc. cords. It's the kind with two sort of oval female prong inputs on the computer end. Anyway, I'd be happy to furnish a picture to anyone who needs to verify. I haven't had it up and running for a couple of years now, and I would like to. I'm really hoping to make it for the first time to the VCF West this year!

Thanks for the offer, but I didn't mean a standard HPIB-HPIB cable. The 12821A disc interface has a 50 conductor edge connector instead of a standard HPIB champ connector. I think the HP part number for the edge connector to HPIB champ connector cable is 59310-60008. If that was really the cable you were talking about then maybe I will take you up on your offer. -Glen >From: Joe <rigdonj(a)cfl.rr.com> >Reply-To: cctalk(a)classiccmp.org >To: cctalk(a)classiccmp.org >Subject: Re: HP CS/80 Instruction Set Programmers Manual (5955-3442) >Date: Fri, 13 Sep 2002 23:10:10 > >Glen, > > Don't bother to build a HP-IB cable.

Hp-85B is really an HP-85?

by fastluck＠email.com

I purchased 4 HP-85Bs at auction yesterday. I was browsing information on HPs at http://www.finseth.com/~fin/hpdata/serial.html, and discovered that one of my "new" machines was manufactured in February, 1982. That's 16 months before the 85B was released, as I understand it. Here's the serial number: 2210A60158. If the first two digits are the number of years since 1960, it was manufactured in 1982. If the next two are the number of weeks since a certain week in November, it was manufactured sometime in February. Is that right? If the HP-85Bs were released on June 1, 1983, this one was either a prototype that rolled off the 85A assembly line, or it's an 85-A in disguise. Do the 85B covers fit the 85A? If so, there's a hapless soul with an 85B that thinks it's an 85. And I own both models. Something else that's interesting: This particular model had an older-style riveted-on serial number plate, while the other three had newer stickers. It s also the only one with a 82936A ROM DRAWER. This drawer has the 00085-15002 PLOTTER/PRINTER ROM. I don't think that's significant, but maybe?? One other thing: The FCC-ID on three models ends with 85B. The model in question either hasn't got one, or I can't find it. If you can shed any light, please do so. I plan to keep one and sell off the other three. If I'm selling an 85-A, I want to make sure that's what I'm advertising. In fact, I may just want to keep two of them. Also, how much is an 85-A worth? I can't find them for sale anywhere. Cheers, John

>I have a couple of CS/80 HPIB disk drives and I am curious how they are >controlled and would like to read the CS/80 programming manual if I can >find one. > >The drives I have are a 9133H which is a combo 20MB hard drive and floppy >drive unit which I have used with my HP IPC, and a 2203A which is a >whopping 670MB dual disk unit which I haven't hooked up to anything yet. >Was that the biggest CS/80 HPIB drive HP ever made?

Glen, Earlier this year I wrote a primitive driver so that my HP1000's could talk to CS/80 drives. Even with the CS80 docs it took weeks of tinkering to make the damned thing work. The CS80 protocol really isn't that difficult. All you need is a HPIB protocol analyzer (Joe has one) and some patience. I can help you get started with the command sequences. Getting the HP1000 to to send all the correct sequences is a much larger problem. I never finished the project but, I can do some basic disk functions. I can boot from the 1000, I can read an write absolute sectors, and I can run progrmas from the disk. This in itself is a major accomlishment. If you need any help getting started, just let me know.

Arbitrary test like this are not real world test and only impress those that don't understand what it takes to interfer with a particular signaling method. There are books written about how to test for interference. Looking at impressive sparks will sell P.T. Barnum's "one every minute" but not me. The environment I used the RS-485 in had RS-232 running at 4800 baud and was seeing error burst on the order of 1 in every 1000 or so bytes. The lines were not any longer than 20 feet. It was more the type of noise source that was important. One needs to know the right spectrum and how the energy was coupled. I wouldn't have expected the Jacob's ladder connected as you described to have introduced hardly any energy in the right form. Dwight

And here I am contributing to the way way off topic..... I understand one of Tom Clancy's novels deals with the subject, flying large airliners into a building. Written in the mid 1990's. I am trying to find out which novel it is, he is very prolific. Paxton Who is looking for a novel to take traveling to Fiji and wondering where he will find the internet there? Hmm.. When I was last there (1990) the telecom system was run on intel multibus and the airport on a microvax. Does that make this on topic.

DECstation 5000/240

by coredump＠gifford.co.uk

I've recently acquired a DECstation 5000/240, a MIPS-based workstation made in 1992. I've got it to respond to the serial console (by removing the frame buffer card) and now I want to try to net-boot it. However, the console PROM is version KN03-AA V5.1b, which is too old to boot via tftp. Version KN03-AA V5.2b would be OK. Now, does anyone know if I can upgrade the console PROM somehow? If so, how? I do have an EPROM programmer, of course! -- John Honniball coredump(a)gifford.co.uk

What TI ultimately put out instead of the much-touted TI-88. (Actually saw one of those a while back on Ebay. Went for about $600 IIRC. The seller was an ex-TI engineer who expressed surprise when I brought up the subject of the TI-99/8, many more of which escaped Engineering and found their way out into the world than said calc.) The 74 has a BASIC interpreter, while the 95 is more an advanced scientific calculator. Both are programmable at the assembly level. The PC-324 printer works with both. Nice machines.

I've got a PDP-11/23 cpu, M8044 32kW memory card, DLV11-J serial card, and an RQDX1 set up, and starting up into ODT.

Four questions: 1a) Does anyone have a pinout for a cable that'll let me hook up the RX50 and MFM drive to the RQDX1 1b) What DIP switch settings should I use on the RQDX1? 1c) Does someone have a bootstrap I can enter using ODT to boot RT-11 off of an RX50 or the hard drive on the RQDX1? 2) I can potentially get a PC set up with a TU58 emulator, does anyone have a bootstrap to load from a TU58?

The computer works great but I have no additional stuff for it like manuals, software or anything. Please email an offer to joacim at melin dot org.

Who was looking for old VMS for an 11/750??

by xds_sigma7＠hotmail.com

Umm looks like a twist-lock connector... *sniff* tastes like a twist-lock connector... *lick* mmm tastes like a twist-lock connector... "Hey mom, um a VAX is FAR more usefull than a dryer! OK? OK!" Nope no three-phase here : ).. Also, the main difference between the "normal" VMS and 11/750 VMS is that generally speaking, it would be difficult to put the CDs in the TU-58... 11/750 VMS distros generally were at at least some portion TU58-based.

brand new AT&T 458 daisy wheel printer

by redodd＠comcast.net

Hello, Today I acquired a BRAND NEW AT&T model 458 serial daisy wheel printer. It's in the original wrapping. It has a printout saying Printer AT&T 458 Number 7829177, then it has a vertical alignment test. If someone wants this before I open the original packing, let me know. Ralph
