At the weekend I got a MicroVax 3300 and a VaxStation II. Badly the keyboard and monitor are lost but I believe a DEC Rainbow100 is a good terminal . Or - I use OS/2 with a lot of comports- is there a terminalprogramm for os/2 with a good VT100 emulation ? So I'll try to give the a new live but with VMS I believe I have no understood. There is no diskdrive connected to the 2 vaxes but I have a lot of tapes, all (It looks so because there are so much) manuals and some cd's. I must look what I got and make a survey . First I make a hardware summary looking what modules , drives and ports are there. If someone can give me a shoot where to start I will be glad .

RCS/RI fleamarket

by aw288＠osfn.org

The Retro Computing Society of Rhode Island will be holding a big flea market to help us make room in our crowded millspace in Providence, Rhode Island. It will be held during our September Open House on the 16th of the month (third Saturday), from roughly 11am to 4pm. If you are going to be around, stop by for a selection of very nicely priced computers - many classic micros (sorry, no Altairs or Imsais!), terminals, printers, maybe a workstation or two, cables, books, all sorts of things you never knew you needed to have. Conditions vary from working and good to dead and (half) buried. Proceeds will of course go to various RCS/RI projects (electrical upgrade, shelves, rent). For directions, see our sight at www.osfn.org/rcs. And of course, there will be the usual amount of RCS/RI fun and geekiness. Show up early, Merle. William Donzelli aw288(a)osfn.org

M8207 anyone?

From: Eric Smith <eric(a)brouhaha.com> >> Suffice to say IDE is not a protocal like SCSI it is a DEVICE >> interface and is somewhat uncooked at that. > >That's a fairly disingenuous claim. Both SCSI and IDE have a "device >interface" (physical layer) and a "protocol" (interpretation of bytes >in various registers and phases). In one sense your right and in another your making it look complex where it's not. For scsi I have to deal with the SCSI interface chip (really nasty if it's 5380!). For IDE I write/read to registers at addresses, al having specific function. there is some sense of sequence and if you want it to work you need to talk to the right one in the right order or garbage ensues. I liken it more to talking to an Z80 SIO raw than making the SIO do HDLC and at the end of that link getting something to happen. IDE is much simpler. I've done SCSI it's not! >IDE in fact has two different protocols, ATA and ATAPI; ATAPI protocol >is by design very similar to SCSI protocol. Already known. >As of SCSI 3, there are *many* different SCSI physical layers and >several different protocols. The difference between IDE and SCSI(any) is that from the CPU side if I want to write the cylinder address to IDE I address the correct register and write (assuming not LBA). For SCSI I first have to talk to the scsi chip and tell it what to say to the disk. The later already is a full layer of protocal from what you want to do. The point originally being that IDE is the simplest disk interface there is of the available sets and from doing a driver for z80 I can say its easier than floppy as the interface if buffered, not time critical reads or writes as the data flys by.

Y2K Patches for V5.03 of RT-11

by jhfine＠idirect.com

Please note: I sent the following post to "alt.sys.pdp11" and "vmsnet.pdp-11". While I presume that almost all of the RT-11 people also follow those two news groups, I thought that there may be a few who don't. It is certainly on topic, since V5.03 of RT-11 was released in 1985. After working with RT-11 for over 20 years starting with V2.0, I was asked about Y2K patches for V5.04G by a customer who finally could wait no longer. I had already produced these Y2K patches for myself, but there seemed to be little if any interest among commercial users in general. So when I set out to provide this customer with the fixes needed to run that version when it was to be used after 31-Dec-1999, it was not necessary to fix everything in V5.04G. Only 7 of the utility programs were needed to be made Y2K compatible, i.e. DIR, PIP, LINK, LIBR, IND, BUP and MACRO. While I am sure that further work could be considered if required (and there was interest), these 7 are probably the most important and frequently used - along with the source code patches needed for the monitor files. Note that these patches have been in continual commercial use for many years without any problems except that when they did their initial checkout, the dates of: 29-Feb-1999, 30-Feb-1999 and 31-Feb-1999 were found to be acceptable to the DATE command. After working with RT-11 for so many years, I had finally accepted that bug as a feature and forgotten to correct it in the KMOVLY.MAC file. At this point, all of my Y2K work bubble is finished and complete, and I would like to make these Y2K patches available to hobby users. However, as far as I understand, only V5.03 of RT-11 qualifies to be used under the Supnik emulator for hobby use free of charge. Since Megan Gentry has already provided some source code patches for RMONSJ, RMONFB and KMOVLY for V5.03 of RT-11, I thought that I could retro-fit the Y2K patches made for V5.04G back into V5.03 so that hobby users could enjoy a mostly Y2K version of RT-11 at this time. I would therefore ask for four things: 1. If anyone, including Megan Gentry, would be willing to host the Y2K patches, preferably the actual final SAV file which should not pose a problem since the distribution SAV file for each of the 7 utilities mentioned is already freely available for download under the restriction that it be used by hobby users under the Supnik emulator. 2. How much interest there actually is in having V5.03 made as Y2K compatible as possible at this time. 3. If there is anyone who would be interested in helping with a beta test. 4. If there is anyone who is interested in helping with any questions as the exactly what should be done, including how to insure that the legal aspects are covered and that the code can not be taken over by any commercial users, not that this latter aspect is likely at this time. At this point, I intend to at the very least, to produce the Y2K patches for one of the above utilities so that it can be seen that there is some definite interest to begin the job. Please note that while I have no work related projects that need to be done at this point, I have a large number of household jobs that have already been delayed for far too long and that it may take a few months before I get into high gear on the Y2K patches for V5.03 project. But, as wives have indicated on many occasions, there is often many a slip between the cup and the lip and she may have other plans that I am not aware of right now. However, I presently consider myself totally in the hobby category at this point in time, especially and in particular as far as RT-11 is concerned. This would allow Mentec to finalize any plans for hobby releases of PDP-11 software, as has been indicated on their web site for over two months, but still nothing has been made public. But in lieu of that happening - which would free up useful time for other enhancements to RT-11, it is hopeful that at least the above 7 utilities in V5.03 of RT-11 could be completed for hobby users sometime next year and perhaps before the end of 2000 if there is sufficient interest - and I don't have too much snow to shovel starting in December:-) NOTE: The following paragraph is really only for "vmsnet.pdp-11"!!!!!! ---------------------------------------------------------------------------------- Finally, and completely contrary to what Stuart Brook implied some months ago when he again complained that I was "whining" about the lack of hobby use licenses for RT-11 by Mentec/Compaq/DEC, I would be only too happy to see Mentec allow V5.07 to be made available to hobby users at this time, as Compaq/DEC have already done with current versions of VMS - and I understand at zero cost. I have included this paragraph ONLY because in the past, there has been this type of response from Stuart. If no adverse comments are received from Stuart or anyone else, then I will assume that there are no objections from Mentec as to the above course of action. I guess that this paragraph can also be construed as a legal notice as to an intended course of action. Any and all feedback would be appreciated. Is there still anyone who even cares? Also, in case anyone is interested, you can download V5.03 at: ftp://gatekeeper.dec.com/pub/digital/sim/software/rtv53swre.tar.Z Sincerely yours, Jerome Fine

CGA graphics

by lionelp＠worldonline.co.za

Hi, Does somebody here know the formulas for calculating the offsets and bits in the CGA memory? Or maybe a quick routine for plotting a pixel? The BIOS routine sure seems SLOW to me. I'm experimenting with these older machines, so I'm working a little with these cool graphics cards! (The CGA is great! Well, I LOVE IT! :-) ) Ciao, Lionel

Any could that become a device driver? Some but it's too involved to talk about without drawing pictures. Suffice to say IDE is not a protocal like SCSI it is a DEVICE interface and is somewhat uncooked at that. It happens the devices on the other side are fairly intelligent and thats an aid to the driver.

Actually a simple driver can work if it's reentrant. However, while RT-11 is fairly simple to write drivers for the other OSs it definately more work as the driver has error recovery and other diagnostice code burried in it. Unix hwoever is a different case as a driver for something like RL02 might be easily bent to work with IDE. Allison

Omnibus boards

by lemay＠cs.umn.edu

Well, now that my PDP-8/E is apparently working, but has no peripherals installed yet, my curiousity over what these 'mystery omnibus boards' do is increasing. If anyone can shed some light, i'm all ears: ---- Computer Operations Inc, C-10450-01. This board intrigues me the most, as someone has written this on the board with a marker: [LINK DEC TAPE 2] It has connectors for 3 ribbon cables to attach, 26 wires per cable. Connectors are labeled: CDJ2, CCJ1, CDJ1. ---- The remaining boards are from VG Data Systems. Someone here once mentioned they had information about some of these boards, and i'd like to know if any of these boards might be useful, or easily modified to be useful: PB-8E-101 PB-8E-102 PB-8E-202 on a standard DEC wirewrap board, should be able to make something out of it. PB-8E-504 2 of this board PB-8E-505 PB-8A-603 PB-8E-644 input connector has written: works as MS30, PDP8 [C:] -Lawrence LeMay

Alphastation help

by Philip.Belben＠powertech.co.uk

Not strictly on topic, since these are fairly new - but they were old enough to be thrown out at work, and I got them for L10 each. Both machines say Alphastation 200 4/100 on the front, and I think Model PB40H-CA on the back. One of them boots openVMS, for which I have no passwords (same old story...). This machine claims her name is Tracey. The other gets to the console prompt (>>>), and I haven't tried booting further. (This machine is in a graphics mode my monitor doesn't like. Time to get a better monitor...) Anyway, if I press ctrl-C when booting Tracey, I can get to the console prompt. SHOW CONFIG then tells me a bit about what's installed in her: SRM Console X3.9-1387 ARC Console 4.1-22 PALcode VMS X5.48-87 OSF X1.35-57 Serial ROM V4.6 Diag ROM V1.6 CPU DECchip 21064-2 at 100MHz pka0.7.0.6.0 SCSI 7 dka0.0.0.6.0 RZ26L (this is whence it boots, BTW) dka100.1.0.6.0 RZ28 mka400.4.0.6.0 TLZ07 (This is a tape drive on the SCSI bus. Presumably at address 4 - forgot to look when I had it in bits) With some random flag adjustments to the BOOT command, I got it into SYSBOOT, which has another load of useless things to SHOW and SET. This seems to be part of VMS, though. Can anyone tell me, off list if necessary: How do I break into OpenVMS from here? If I put in the floppy and CDROM drives from the other machine, will it recognise them automatically on boot, and if not, how do I tell it they're there? What OS are available, and whence do I obtain them? I found a FAQ somewhere at compaq.com about installing Linux on some models of Alphaserver - not mine, but could be helpful. Also, what are the various OS useful for? What are the HDDs? (How big, how easy to replace? They are both SCSI afaik) If I decide to stay with VMS, are there any good books on the subject? I have almost no VMS experience (enough to know that I have to PURGE my files from time to time to stop my disk filling up, but that's about it!)

Tim's own version of the Catweasel/Compaticard/whatever

by allisonp＠world.std.com

From: Richard Erlacher <richard(a)idcomm.com> To: classiccmp(a)classiccmp.org <classiccmp(a)classiccmp.org> Date: Wednesday, July 05, 2000 7:30 PM Subject: Re: Tim's own version of the Catweasel/Compaticard/whatever >You may be onto something, Tim, but I'd make one observation here. The >signal on pin2 of the 8" drive cable, though often driven with the >1793's TG43 signal, does not turn write precomp on and off, but, rather, >reduces the write current to the heads. This reduces the amplitude of the >signal In many cases it's also used to alter write precomp. Most all have some precomp (Esp DD controllers) and for the TG43 case they alter the precomp to further compensate for bit shift due to the close magnetic domains. >driving the heads, hence reduces the overall amplitude of the recovered >signal as well. That same signal is used to enable write precompensation on Bogus. the levels are dealt with in the read amps with margin as well. What's changing of the write current really impacts is the read bit shift (aka peak shift) as the bit density goes up (inner tracks are shorter than outer). >some controllers, many of which use a less-than-ideal timebase to define >the precompensation offsets imposed on the data stream. This is true, or worse used oneshots. generally the time base for the bit encoding was always a crystal with not worse than 200ppm error and less than 50ppm drift. The typical system was usually within 50ppm of exact and drifted less than 25ppm over temperature extremes. Often the actual data rate was far lower than that reference(usually 1/4 or 1/8th). >Do you think you could take a stab at swapping the timebase on your >Catweasel board with a 32 MHz crystal? I think that would be VERY >illuminating, particularly where these precomp/write-current-related >effects >are concerned, because phase noise introduced by the deviation of the >Catweasel timebase from a harmonic of the data rate adds confusion. There lies a connundrum, study the media and the magnetic domains therein or get the data? A lower clock would be adaquate for getting the data. Further, while I was studying digital PLL state machines I found a point where increasing the clock (greater resolution) produced sharply reduced improvement. Signal processing theory (analog) suggests the same. From: Tim Mann <mann(a)pa.dec.com>: >> So, what's the heuristic? It's quite crude and oversimplified too, >> seems to work pretty well. The general idea is that if an interval is >> a bit off from what you were expecting it to be, multiply the error by >> some factor around 0.5 to 0.8 (you sometimes have to tune it for each >> disk if they are particularly bad), and add that to the next interval I'd suggest some factor less than .5, flux shift errors on floppies rarely move a great amount unless the spindle bearings are rattling loose. Actually based on media and expected recording rate it's possible to plug in a set of expected timing windows and add/subtract a "precompenstation" window amount based on adjacent bits. For example adjacent ones or zeros (especially more than two bits) tend to spread or compress over patterns like alternating ones and zeros. Further with all the "timing image" in a memory it should be possible to look at longer strings of transistions and do simple predictive forcasting (software PLL). Add to that the encoding form (FM, MFM, M2FM, RLL or GCR), and previous bits history it should be straightforward enough to predict the likely next transistion(s) be they one or zero. It is serediptious that the code you have effectively accomplishes a tracking filter (type of PLL). Why, many of the parameters on the media like peakshift and other behavours tend to average themselves and cancle. Most of this stuff is not rocket science, it does however require seeing into the set of abstractions to make them obvious. Allison

New finds: DEC/DSD/MDB

by schoedel＠kw.igs.net

Got an 11/23 in a third-party enclosure ("Transduction 11/BLUE15") along with a DSD dual floppy drive. Haven't powered it on yet; the drive enclosure's fan has seized, and the main enclosure has a key switch.... As I found it, the arrangement of cards has gaps, unless the backplane is *really* weird. The backplane itself is MDB model MLSI 40328 -- anyone know the layout? Any reason I couldn't just move this into a BA23? The only non-obvious card in the system is an MDB DR11B... is this a parallel interface? -- Kevin Schoedel schoedel(a)kw.igs.net

Why I love my IBM 3090 ... (fwd)

by spectre＠stockholm.ptloma.edu

Okay, is this all true? I've never had the joy of VM. -- forwarded message -- Newsgroups: rec.humor.funny.reruns From: 22414843(a)wsuvm1.bitnet (Chet) Subject: More IBM 3090/VM Humor, smirk Why I like the IBM 3090: First, there's the wonderful operating system, VM/SP which has SO many advantages! Here are some of my favorites! 1. All of your files are in the same directory, you don't have to worry about subdirectories and other nonsense, 2. For file names, not only do you get a file name, but you also get a file type AND a file mode, with the name and type each being an astounding 8 characters, plus a 2 character file mode, way more than I ever had on my Apple II, 3. If you create a small file, it automatically makes sure it takes up one 4K block on your disk, so you can add up to 4K of data to the same file and not take any more disk space!!! WOW!!!!! 4. When you get an account you get an ENTIRE cylinder to yourself, an amazing 465K, which is more than my 5 1/4 inch, single sided, low density PC disk, 5. If a FORTRAN file is too long (250 lines) to compile on your disk because the temp files fill up your cylinder, all you have to do is unlink your A disk, create a big temporary disk, attach that as your A disk, attach your old A disk as another disk, copy the source file to the new A disk, then compile it, 6. You never have to worry about background processes, redirection, or piping because the 3090 doesn't have any! Or command histories! 7. Or here (WSU) we are privileged to have RESLIM, which makes sure that you don't use any more CPU time than you want to or have to, 8. We also have system administrators who also make sure we don't use more CPU than we have to, not to mention they tell us what we can and can not do, and what they think they legally can and can not do, such as maintenance on our accounts to make sure there is nothing wrong with any of our personal files, 9. If any files have sat in your reader/mailbox too long, they will automatically be discarded for you, 10. And finally, all of the USEFUL on-line help! All you have to know is the name of the command and whether it is in CP or CMS or SOFTWARE or one of the other help menus, and you can get a GREAT description of that command AND some examples how to use it like you would want to every day! Not only is the operating system fantastic, they have an AWESOME full screen editor, XEDIT. Boy, it's quite a step up from EDLIN on my PC! Just look how powerful it is: 1. If you want to move your cursor to the middle of the screen, all you do is hold down the arrow keys until you get there. 2. If you wanna delete a whole bunch of characters in the middle of the line all you have to do is hold down the DELETE key until they all magically disappear. 3. If you wanna insert something, all you do is hit the INSERT key and type in what you want, unless it's too long for that line, then all you gotta do is split the line where you want by using the PF11 key, which if you are on a VT100 is just an ESC minus sign. 4. After you do any commands in that neat prefix area, your cursor almost always goes back to the command line at the bottom of the screen. 5. You never have to worry about anything nasty like tab keys, there are no tab stops by default (unless you wanna set them). 6. And, unless you tell it otherwise, XEDIT always creates fixed length lines of 80 characters, so if you ever want to put more stuff on the same line sometime later, there is room for it!! Add to all of this such things as COBOL, disk linking, EBCDIC character set (I mean who says J should follow I?), and even some AWESOME graphics capabilities, and you'll have to agree that the IBM 3090 is the system for me!!!! (Thanx to those people who sent me some of the ideas used herein) -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- FORTUNE: Today is an excellent day to have a totally rotten day. -----------

Most parallel ports ahve enough bidirectional lines and the 8bit data is bidirectional (only the old XT ports aren't). Look into a m7941 (DRV11) parallel line unit sa that give you lots of bits for parallel IO. Another would be the M7950 DRV-11B general purpose DMA interface (also a parallel IO). The latest one was the DRV-11J (M8049) and that has enough lines to interface anything (32 in and 32 out). The later boards could possibly even be enough to fake the IDE interface directly.

Visit the VCF website for complete details! VCF AND CAEX2000 TOGETHER IN ONE VENUE! The VCF is proud to announce it is being held in conjunction with California Extreme 2000, the world's premier classic arcade game extravaganza! Hundreds of classic arcade and pinball games beeping, buzzing and booming. The VCF and CAEX2000 share the same venue, making it easy to attend both events. Even better, admission is reduced for those who do come to both events (details at the door)! For complete details on California Extreme 2000 see: http://www.caextreme.org SPEAKERS AND WORKSHOPS Every year, the VCF assembles an amazing line-up of talks and workshops. This gives attendees an opportunity to interact with the people who laid the foundation for computing today, as well as those who are helping to document and preserve it. Our speaker roster so far includes: Bill Godbout Bill was the King of S-100 for well over a decade, providing kits, boards and complete systems for the hobbyist and businesses worldwide. Godbout and CompuPro products were a basic staple for computer hobbyist's throughout the late-70s and 80s. Jim Warren Jim was responsible for bringing about the West Coast Computer Faire, the seminal computing event of the 70s and 80s. Jim will be waxing poetic about the political activism that transmogrified into the microcomputer revolution of the 70s. Jim will be engaging in a roundtable discussion with fellow revolutionary Larry Tesler. Larry Tesler Larry has left his mark at two of the Silicon Valley's most hallowed institutions: Xerox PARC and Apple. But Larry's vision began well before he went on to help create the foundations of modern day computing. Larry will join Jim Warren in a roundtable discsussion. Paul Freiberger Sixteen years ago, Paul and Mike surveyed the Silicon Mike Swaine Valley and then wrote about it. Their tome, _Fire in the Valley_, has become a legend in its own right. Paul and Mike will be sharing what they learned in writing this biography of the center of the high tech world. Bring your own copy to have it signed! Christine Finn Christine is an archaeologist. So how did her research lead her to vintage computing? Christine is studying the Silicon Valley and the effects it has had in bringing about a global transformation in the way we live. Christine will tell us why it happened in the Santa Clara valley of California. Curt Vendel Curt is the founder of the Atari Historical Society. On his website (http://www.atari-history.com/) he documents the amazing ups and downs of one of computing's most celebrated and innovative companies. Curt will also be bringing along a great interactive Atari exhibit. Jim Willing Jim, our Official VCF Celebrity, is back to wow you with more amazing words of wisdom, incantations of innuendo and sentences of sarcasm. This year in two separate talks he takes on the topics of computer collecting and computer preservation: one is not exclusive of the other! Dwight Elvey Dwight has achieved the ultimate in computer restoration. He acquired a relatively unknown mini- computer from the early 70s, the Nicolet 1080, resurrected it, wrote a cross-compiler for it, and brought it back to life. This talk is perfect for those wishing to take on their own restoration projects but don't know where to start. More speakers to be announced soon! Check the VCF website for the latest updates: http://www.vintage.org/2000/speakers.html EXHIBIT YOUR VINTAGE COMPUTER Vintage Computer Collectors: we want you!

Palasm?

There's a plug-in adapter called a LogicPak, and that can take a PALASM Design Adapter, an H&L Design Adapter, or one of several programming/test adapters. I've got some of these (PALASM and a couple of p/t adapters) as well as manuals but haven't used them. With the PALASM Design Adapter you can apparently send the programmer your logic equations and have it generate the fuse map and test vectors. Then I guess you plug in one of the p/t adapters to program the actual device because the PALASM Design Adapter doesn't have a socket on top. Like I said, I haven't actually used this, and barely cracked the manuals -- it was gradually tossed by a previous employer and at a price of $0 I figured it would make a useful [[E]P]ROM reader and programmer. Which is sort of what I've been doing with it lately -- writing a Tcl/Expect script to control the 29A w/UniPak 2 and read data from ROMs. It's not what I'd call baked yet (all it does is read a 27512), but I'll post a note when it's a bit more complete. -Frank McConnell

If I need SCSI I have a CDM200 I can borrow from the VAX for CDrom use or whatever. I happen to like RT11FB or XM so a rx33 plus three RD52(Quantum D540s) on a RQDX3 is a roomy setup with RL02 and RX02. Come to think of it one of the RD53s boots as RSTS. If there were any PDP-11 config I'd love to do it's a micro Qbus box with say 11/23 IDE and RX23/24 3.5" drives in a PC minitower or smaller format. Envision this (all dual width cards): 11/23 m8186 KDF-11A (11/23 Q22, I have one overclocked). boot M8021 MRV11 (Eprom card with boot) ram M8059(x4) MSV11LK (4x =1mb) serial M8043 DLV11j 4port serial One possible Disk system, all DEC disk M7555 RQDX3 M9058 disk distribution flop TEACFD55GFV RX33 HD RD52 RD52 OR hybrid DEC: CMD200, RZ23, Cdrom all in a H9281-AC(12 dual slots) which has a footprint nearly as large as MINI AT sized card though much thicker. ;-) I also have a few M7142s, VK170 base Vt52 video on a dial card so the system would use a mono CRT and a keyboard like a real PC. I should do it as I have all the bits and it would be fair system perfomance wise. Not bad for 1984-87 technology! Allison

AS400 console cable pinout?

by geoffrob＠stmarks.pp.catholic.edu.au

Anyone have a pinout for the "magic cable" listed below. It's the console cable for an IBM AS/400. It's just a DB25M-DB25F, but has some magic wiring to make it work as a console. I have a 3477 Terminal that should suit, and there is a 2612 in the AS. Have a VTxxx if it can speak ascii, but I STILL need the pinout. (I refuse to buy one from IBM on general principles - even assuming it didn't cost 2 arms and 2 legs, I might need a sys pwd and have wasted my time and money, don't mind the time, but the money is another thing entirely.) Have several Twinax terms and cables as well, however the AS doesn't have anything in it that speaks twinax. Part Number 46G0450 or 46G0479 Feature Code 9026 or 9027 I'd really like to get this AS/400 to work, it seems to boot, so I'm assuming it ain't gonna ask for the system password crap. Can't tell until/if I get a console working on it. Can some kind soul (Eric?) talk me through the process? Off list if you prefer.....

LPV11 for Qbus is M8027 (lp05/la180) but with the right cable kit also work with LP25/26/27, LN01 and a few others with data products I/F It wouldn't be hard to use that with Centronics. other choices are M7941 (DRV11 parallel line unit) or LAV11 printer interface(M7949). for most small vaxen the serial interfaced DEC printers was the common choice.

AS/400?

by geoffrob＠stmarks.pp.catholic.edu.au

Anyone out there know anything about IBM AS/400's? Looking for some info on the following system. This is the first AS/400 I've ever seen, so bear with me a little. I'm not familiar with IBM stuff at all (pc's excepted) Digital Vaxen, yes. I picked up a Type 9402-2xx with 4 x Type 0662 1.05Gb SCSI Hard drives and a 2Gb Tape drive for $30 at an auction in Adelaide last Friday. Cool looking ~Microvax II sized box, solid metal, with a black plastic 5 piece shroud. (The back bulkhead cover is missing). A badge with the IBM logo is on the front shroud, with AS/400 Advanced also in the badge. Thing appears to boot, rattles away at drives, status display is live etc, but have no idea what/where/how to connect anything to it. Have numerous cables etc, and an IBM 3477 terminal I found in my back room. Looking for advice on how/what to connect to it. Not sure if this fits in the 10 year rule, though the AS/400 itself goes way back, this machine appears more recent. Early/Mid 90's? It appears to have at least 16mb of ram on a board inside. (2 x IBM 72 pin SIMMS). There is a DB25F on the back that appears to go to what I take to be the main board, (which has part no 74G9701) that I assume is a console port (do these have a console port?) the ram is on a board with a part number of 74G9722 which I assume is a memory expansion board of some description. I suspect it's running some version of OS/400 rather than SSP (I think that's the original O/S for these). This appears to be a RISC machine based on the pic in the docs on the IBM site, which show that it is a Version 3 AS/400. (Whatever that means.) The following modules are fitted in the rear bulkhead. Searching for module no's on the web found virtually nothing to my surprise. 2612 x 1 (A chance encounter in a newsgroup reveals this is an EIA 232/V.24 One-Line Adapter) I translate that as a serial port. There is a blanking panel below it that would probably allow another to be fitted there. 2609 x 2 I have some cables that mate to these, IBM P/N 21F9345 (9843),they terminate in a 'black box' with 2 x DB25M's minus pins 9, 14 and 16, marked P1 and P2 which I suspect are terminal ports. I have 4 x P/N 22F0152 (9835) DB25F to DB25M, with pins 9-14, 16 and 19 missing, these were hanging off the DB25M's on the 'black boxes'. I assume these are to connect to a terminal, they certainly fit one of the ports on the 3477. One 22F0152 cable has an oddball DB25F in a plastic shell that seems to be "wrapped around" the cable, it turns freely, it has 8 wires that each jump one pin to another pin, and no connection to the cable itself. Some kind of loopback connector? Spare part? Inductive pickup? Who knows? 264A (Blank/space filler) 2641 (Blank/space filler) 2623 (some kind of interface, the 2 x 2609's fit into it) None of these appear to be an ethernet connector, so I will have to hunt up one of those too I guess. Some 3180 "R2D2" Twinax based terms and cables came with it, however there does not appear to be any kind of Twinax connector on the machine. There were also some 'clone' type terms with it, but someone else got them. I suspect these ran off the IBM's web site has some docs etc available, but the physics of what and how to connect terms etc are buried deep if they even exist there. >From sticker on metal side of unit (Under the black plastic cover) Type 9402 S/N 10-1428A Release Level V3ROM5 PTF Level C4179305 TSP (Y/N) : NO Software License Type: NONE On a small sticker on the back panel Type 9402-2xx S/N 10-1428A MS9402101428A Any help appreciated, replies off list if this is off topic most welcome..

Considering that CDroms, IDE ZIPs, Superdisks and even big hard drives all can be found real cheap this has appeal. What makes it mildly hard to do is PDP-11 (Q, U or any) All do a read before write and IDE control registers don't like that. So you have to do like the DL cards were the TX and RX registers are different addresses. I might add that IDE is much faster than ZIP drives, I have a Parallel port IDE disk and a Syquest 270 and both scream compared to ZIP. Allison

M8207 anyone?

by dburrows＠netpath.net

Just hang it on a SCSI controller. If it is an internal SCSI zip you can set the SCSI id to whatever you want. If it is an external you will have to use the CMD/Emulex or whatever firmware to map ID 5or 6 to something lower. The other aleternative is to leave it at 5 and SYSGEN 7 DU devices to your SCSI controller. (My archive system is that way) RSX11M+ V4.6 warns you but allows it. In fact that system is doing another sysgen as I type this. Had to add a few other devices. I have routinely used various ZIP and JAZ drives on both CMD CQD220T/M and Emulex UC08's. However with the batch of RZ25's I got 6 + months ago I have gone to using them as ZIP drives. They were cheaper than ZIP media. They also don't eject themselves when you dismount them. I had to come back up to the office a while back when I dismounted one my mistake from the house via telnet.

PDP 11-23 questions

by xds_sigma7＠hotmail.com

Heh, PDP-11's are *light*... the last computer I had shipped to me, which was only the CPU, disk controller, and hard drive, along with a terminal, a graphics interface box, 2 terminal controllers and a rack of manuals weighed in at 5700 pounds... The trick with shipping big stuff is to get it from big companies, and then instead of choosing the shipper yourself, you ask them who they use most, and have them coordinate it in-house... It's truly disgusting how much of a break the big shippers get versus a single-time shipment from somewhere... As an example, the 5700lbs of stuff cost me $801.80 to ship, whereas my Burroughs B80, which they said weighs 800lbs (yeah right!), they rated it as if it weighed 1000lbs, and for that single machine it cost $817.07 or so... The rate on the 5700lbs was like 31 bucks a mile and the other one was 81 a mile, but since the 5700lbs was shipped by a major user of the carrier, I got like a $1500 "Incentive" i.e. discount... Talk about highway robbery! Will J ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

WTT: M8207 anyone?

by cmcmanis＠mcmanis.com

Hi, I've got several Unibus LP11 interfaces and I was wondering if anyone was interested in trading a couple for M8207's (Q-bus version) of same? I'd like to put a centronics printer port on my VAX and test out some code in NetBSD for said port. --Chuck

Web page for ClassicCmp info

by retro＠retrobits.com

Hi everybody, I'm (finally) getting around to write Part III of the "Collecting" article on retrobits.com. I'd like to include a web page reference for parties interested in getting more info (and subscribing) to the ClassicCmp list. I found multiple info sites out there, but it's not clear to me which is the most up-to-date and authoritative. Can someone provide me the "official" web page for ClassicCmp? (Or at least, where should I send folks who want to find out more...) Thanks! - Earl Earl Evans retro(a)retrobits.com Enjoy retrocomputing today!

PDP 11-23 questions

by ajp166＠bellatlantic.net

From: healyzh(a)aracnet.com <healyzh(a)aracnet.com> >Yes, $40-50 isn't bad, but as mentioned you've got to consider shipping, plus >it will probably go for quiet a bit more. Never ship a PDP-11... way to heavy. >Ah, OK. I should have known there was a /23 equivalent of the dual and quad >hieght /73's. Yep! M8189 come in two flavors, the difference is the roms. The +(B) will boot MSCP while the older ones don't know the RQDXn Controller. The 11/23+ (11/23B) was used in the BA23 box aka micro pdp11/53. >> With RL01/2, RX01/2 and BA11S or N box that could be stuffed into a 36" >> small office rack, likely it's a 40, 48" or larger one. > >Hmmm, a 36" rack could be fun!!! I've set up two RL02 and a RX02 in a 48" rack with BA11S and a few filler pannels. A 36" rack is very doable too. The RX02 is ~11in, the RL01/2 is ~12in and BA11S/N boxes are ~6" you might get that in a 30" rack. An 11/23 with 256kb and RL02s will run V7 if it's not the I&D version. Allison

Sony CPD 1302

In a message dated 08/08/2000 10:48:47 AM Eastern Daylight Time, ghldbrd(a)ccp.com writes: > According to the back > panel it is an analog RGB with a DB9 female input.

We obtained a whole pallet of these two or three years ago, and still use one (too scarred-up to sell) for one of our test-bench monitors. When I asked the seller about the nine-pin connector he said they required a "multisync cable" and included them with the monitors. These are VGA monitors and I've run them up to 1024x768 with good results. Have fun! Glen 0/0

PDP 11-23 questions

by ajp166＠bellatlantic.net

>Smile, and keep your eyes open for a better system. As has been pointed out For 40$ thats not bad but it's incomplete unless the disks are there then it's much more. If you were seriously into PDP11 and shipping it didn't cost a bomb $40-50 isn't much for spares. >it doesn't have any serial port boards and it took Allison's note to get me >to wondering if there are even any on the CPU board... There are on my >/23+'s, but not on my /23. There is a good chance that isn't a usable >system. Serial cards are gotten cheap. The M8189 (11/23 and 11/23+ <or B>) has two serial ports and the equvilent of the M8012 on it, the M8186 does not have anything but basic CPU so you need the M8012 and a serial line card or two. Either CPU can be used in the same box. Besides if that is a complete system it's probably in a 4' 19" rack! With RL01/2, RX01/2 and BA11S or N box that could be stuffed into a 36" small office rack, likely it's a 40, 48" or larger one. Allison

Apple IIc (not IIC+) details

by mranalog＠home.com

Eric Smith <eric(a)brouhaha.com> said: > The //c disk controller is for all reasonable intents and purposes the same > as the Disk ][ controller used in the Apple ][ and ][+, simply with a > different connector pinout (D-subminature 19 pin instead of a 2x10 header). > It's reduced from seven chips to one, but functions the same. In fact I remember about 1988, buying a small connector from Jameco. It had pins on both sides almost like a wire wrap header. (I seem to me that the pins were straight through). One side plugged into the //c floppy port and the other side plugged into the ribbon cable from the Apple ][ drive. And it cost two or three dollars. I couldn't find it on their web site just now, but I was surprised to see that they still sell power supplies for the Apple ][,][+,][e. --Doug ==================================================== Doug Coward Curator Analog Computer Museum and History Center http://www.best.com/~dcoward/analog ====================================================

> Well, since you're into Linux, you might want to take a look at: > http://minnie.cs.adfa.oz.au/PUPS/ > I'm not sure though if you'd be able to get any form of UNIX up on this > system. There's a binary V6 system in the PUPS Unix archives that will run on a 11/23 with 64K and attached RL02 drives. I rescued it from a pile at a UBC SERF sale about 4 years ago. Note that the "Standard" V6 system doesn't support RL02's; the exact lineage of this find hasn't been completely researched yet - and it may never be, as the sources haven't been found. Tim.
