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

Need power plug

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.

John, Nope. I'm running mine on a standard 3-conductor cable, 12AWG. It draws between 700 and 900 watts, depending on if I insert a full complement of memory (8MB) and the FPU. - Matt At 01:04 PM 9/15/2002 -0600, you wrote: >Do these things require (as I have heard rumored) 240-volt 3-phase >power? > >Thanks >John Matthew Sell Programmer On Time Support, Inc. www.ontimesupport.com (281) 296-6066 Join the Metrology Software discussion group METLIST! http://www.ontimesupport.com/subscribe_t&c.html.

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

HP CS/80 Instruction Set Programmers Manual (5955-3442)

by steven_j_robertson＠hotmail.com

>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? Some day I'll try >interfacing one of the drives to the HP 2117F box I have if I can ever >figure out how to get it to power up. 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. See ya, SteveRob _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

It's basically a pocket version of the CC40. It's possible to adapt a CC40 Hexbus cable and peripherals to it, even, according to the article. http://www.hightechsolutions.com/Accesories.htm for TI-74 and 95 stuff. They appear to be out of the computers, but the PC-324, modules, and other accessories are available. jbdigriz

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

IN BAD TASTE: Putting the blame where it belongs?

by Innfogra＠aol.com

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

Zane September 12, 2002 Warren Zevon has inoperable cancer Sep. 12, 2002 "Werewolves of London" rocker Warren Zevon, the singer-songwriter whose satire, cynicism and wit went on display in the 1978 album "Excitable Boy," has been diagnosed with inoperable lung cancer, his publicist said Thursday. Zevon, 55, was told of the terminal diagnosis last month by doctors and he is spending time with his grown children, spokeswoman Diana Baron said. The entertainer lives in Los Angeles. "He has been diagnosed with lung cancer which has advanced to an untreatable stage," she said, adding he's writing and recording as many songs as possible and will be in the recording studio next week.

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. You can still by them new/refurbed from an outfit in the Pac. Northwest. Name of which escapes me at the moment.) jbdigriz

It's almost there

by pat＠purdueriots.com

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. I've got an ST225 'MFM' interface drive and an RX50 I'd like to hook up, but no cab kit for the RQDX1. 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?
