PR1ME 2550 Additional

by jpl15＠netcom.com

I forgot one of the Prime peripherals.. comes from trying to type when falling asleep.. check out all those transposition typos.. This rig had at one time a Printronix P300, and has the cable set up for the Dataproducts interface. I have a P300, tho it is not the one originally with the computer. I had intended the P300 to be used as a line printer with the PDP stuff, but a suitable bribe and/or trade could possibly sway my thinking. Cheers John

Need a RS232 interface transputer tram

by edick＠idcomm.com

I wonder what happened to the "app-note" type designs that were floating around about 15 years ago. It was hard to get them to stop sending them to me when I was working at the "Rocket Ranch." They were purported to be small and simple, intended for ganging up on a task, and not my cup of tea, so I never bothered to save them. They must have had a serial (RS-232) version, because I considered them for a hugely parallel test fixture for proving that yet another Honeywell-Bull system proposed to the Pentagon didn't work as advertised. We built a single board system which filled a 6' rack, with 68701's on both sides to perform the test. It proved the system didn't work, but the Pentagon bought it anyway. <sigh> It's nice to know that your work matters.

Prime 2550 possibly available

by jpl15＠netcom.com

I have been thinkin' lately that perhaps I oughta stick strictly to DEC Stuff... and I am trying to reduce the tonnage around here. So I gets to lookin' at the bee-yoo-tee-full PR1ME mainframe that I actually paid to rescue. And it ain't got no DEC logos on it nowhere. Is anyone withing the purview of The List and within trucking distance of LA CA interested in this machine? It is in working condition, has a lot of software loaded on it (exactly how mnay app I don't know) and has extensive and complete software doc. It laso has several 1/2" tapes, tow with the OS and one 7"-er marked 'games'. Peripherals are 1.2G SCSI Seagate Sabre w/front panel, 350M CDC SMD (spare SMD avail) 32 user ports and Kennedy 9100 1/2" drive. Power runs on 110 single phase... not in original cabinet, so some cooling fans will need to be added. Unit is in 6' rack with casters, Kennedy is seperate and loose, tho I have the rack slides for it. 35 serial cables are included, and one spare CPU and two spare 1M memory cards. The original control panel is also present and functioning. IDEALLY... I'd like to sell it, but the price is variable according to the situation of the prospective adopter. I *did* pay good money to keep this old girl out of the scrapper's. Any van or small pickup truck can handle the whole thing in one go. I want it to be loved and *run* and played with. Now's your chance to do a little Pick hacking... from what I read in the Doco, that's included in there somewhere. OS rev is 20.2.8 for the PR1ME literate among you. Any takers in or near SoCal?

OT: patenting an old year/date concept, to make millions

by CLASSICCMP＠trailing-edge.com

>OK, that just how the date was entered, not how it was stored internally, >but it's not that different. I would claim this is certainly 'prior art'. >And I doubt if this is the first time it was done either. Just because it was done before doesn't mean that a patent won't be granted, especially when it comes to patenting algorithms. Witness the discussions in comp.arch earlier this year about IBM patenting a well-known (has been in textbooks since the 1960's) algorithm for converting multi-digit decimal numbers to binary. Tim.

Convergent Technologies

by mmcfadden＠cmh.edu

I just acquired 3 convergent technologies computers. They are a series of modules that plug together, each module is the size of a very thick book. They have external power supplies with a 2 foot long cable with snap connectors to connect power supply to module. The modules plus together along the side and a latch locks the connection. No tools needed to add/remove memory. The computers power up and LED's come on. The information I got from the web doesn't say what kind of CPU chip was used, what the computers were designed for and if they are still supported. From several web searches I think these machines ran CTOS which was dropped by Unisys. The date on the inside of the cases is 1983 and 1984. Module 1 CPU with 3 extra memory modules, one labeled datapoint, one convergent tech, one burroughs Module 2 Hard disk 10MB ST225 Module 3 5 1/4 floppy drive Module 1 CPU Module 2 hard disk 90MB Module 3 5 1/4 floppy Module 4 40-60 MB tape drive I picked up 8 power supplies, and 10-20 cables, no manuals. One cable has two right angle db9 connectors that seem to be made to connect "cluster controller" connector in the side of the CPU. Other looks like terminal cable. Does anyone know what kind of terminal would work? Any other information would be appreciated. Thanks Mike McFadden

by yakowenk＠cs.unc.edu

Hey all, it turns out that "soon" isn't quite as soon as the usual definition. This time we may have several weeks, maybe even months(!), to respond. About a dozen people have expressed an interest (and all are getting this message BCC'd directly). Until I hear otherwise, I'm assuming this guy wants a single contact point, and not a barrage of individual requests. But I will ask him about that; if it is okay by him, then I'll just pass on his contact info and get the #@(& out of the way. Still no more info on what machines are there, and no precise time limit. Will keep you posted. Cheers, Bill.

apple II DOS diskettes - can they be made on a PC?

by jlwest＠tseinc.com

I just got an apple ][+ and two disk ][ units. I have no diskettes for it though. Specifically, I'd like to get a copy of the disks that come with a disk ][ unit. This would be the DOS disks (16 sector version I seem to recall???) and any example disks and/or utilities that normally came with it. So - two questions - 1) Can the disks be made on a PC clone system 5.25 drive with something like rawrite or teledisk? and 2) Can someone point me to where these images can be obtained on the net or would a kind sole email me the images? I don't remember much about the apple ][+, it's been almost 20 years since I played with one so I hope the above questions are somewhat clear :) Thanks in advance for any tips and/or advice!

Looking for old equipment -- please help!

by truthanl＠oclc.org

Hello list. I have a mixed bag of classic gear. I have a Plessy 6600/6700 ( LSI 11/24) Circa Jan 84. 80 Meg Fujitsu HD, Cipher F800 ? Tape. I have a D116 mini computer with which is what I think is a Nova 3 Clone- similar Front Panel - paper tape. and a slew of Serial ports. I have a DG3 (Kennedy? tape transport) TI 990/10 CPU w/ Front Panel , CPU Expansion Chassis Unit, Two 10 Meg removable hard drives and scores of serial ports - This was part of a Paradyne modem analysis system Each modem had a primary data channel and an analysis port where the TI 990 tracked modem maladies like lost carrier, receive level in db etc. - Parameters One TI 990 watched 256 2400 Baud modems, Second Hd Came from a second system I could not get. In Its heyday we had over 300 dedicated lines. Other systems I have: MicroVax with VMS 4.2? Another Cipher F880 tape drive. TRS-80 Coco with 32 MB ram ET3400 Microprocessor trainer I havent been able to figure out which system I should start on, Although I have always interested in fnding Linux for the MicroVax. I think the MicroVax also has an 80 Meg HD, 4 Serial ports, I MB RAM I have never been able to get the MicroVax floppy drive (800KB?) to respond. I just discovered this list last week, And now I have HOPE that I can get user help in assessing what I have, imagine the possibilities!!! Sincerely, Full Garage too..

Never were truer words spoken by a wiser man ;-) My first mess of DEC equipment came from someone who called me. The next thing I know I am wondering where to store it all while I sort it out. The latest call was to see if I was interested in a mess of Intel boxes. Hard to say no, when who knows what goodies might be lurking inside the next machine you pull the cover off of. One thing early on is to convince your significant other that there is nothing abnormal about having multiple computers in multiple rooms of the house. Mike

OT: IBM Scanner model 9066

by max82＠surfree.com

Hi, I bought an IBM 9066 scanner at the MIT flea, and can't find any mention of it on the IBM website. As you might imagine, I need drivers. The scanner is by and large labelled in Japanese. Web searches turn up nothing but other people asking the same question in bulletin boards (with no answer). Does anyone here have drivers? Thanks

Freebie alert: CDC 9766 SMD drive

by jallain＠databaseamerica.com

Dumpster-Dive alert from a Newbie. Two Control Data Corp 9766 Storage Module Drive units to go ** FREE ** to a good home in the tri state (New York, New Jersey, Conecticut this time) area. These are the Classic drives from the late 70's that everybody at the time is probably familliar with ( Open the top like a clotheswasher, lock in a removable 300MB platter array, push the start button & go ) I don't remember the DEC designator for this but I'm positive that Many companies re-marketed this as their own component to their MiniComputer offerings, they were everywhere, I used one in in 1982, but I don't need three now. These two were taken from a system deactivated just recently. One of the diskpacks was marked something like "Backup Nov-1997" so it's a pretty good guess that everything was working. They are sitting safe in an office right now, but Pls. act fast if you're interested. FYI JEA (John Allain)

1.44M floppy on Color Computer (was Re: Ebay reaches new low)

by allisonp＠world.std.com

<> Is this a problem? Firstly, who says you'd use an MS-DOS format -- the <> CoCo uses 256 byte sectors for virtually everything, and I'd suggest <> keeping to that on the HD disks, just having more of them. As to being <> more wasteful, well, MS-DOS 360K (and 720K) disks fit 9 512byte sectors <> on a track, the CoCo fits 18 256byte sectors. Looks the same to me. My ampro and Kaypro run a 10x512 and 5x1024 format that yeilds 781k. If those sector sizes are awkward then bufer them for host deblocking. Doing that will also get you a mini-cache with a small perfomance increase.. Allison

Computers and other hardware containing the 8008 microprocessor

What you've said here is probably the case. THIS environment is the only one in which I've ever encountered the claim that the 4004 was in any way related to the 8008, eexcept for the label.

Just picked up a HUGE PDP-8I and PDP-15 and .....

by dylanb＠sympatico.ca

Well Chris... not too hard of a find. I bought everything from one member here! (I usually buy most of my systems from factories. Kevin Stumpf of (www.unusual.on.ca) sold me: PDP-8/S PDP-15 PDP-8I (and this baby is mint...... I plugged it in and every bulb worked and it's real happy!) About a 1000 flip chips All the manuals and docs, software.. even 5 trays of PDP 5,5/8 decus programs... Nova-2 Nova-3 A skid full of PDP 8, PDP 11, and Nova spares and parts and docs... None of them were running or had been plugged in. All of them came from McMaster University LAST YEAR! I have to hand it to Kevin. He did not miss a SINGLE piece of documentation or software. I don't think he ever really expected to sell all of it. I bought the 8/S first. (How we got in contact is really funny. I just finished scrapping an 8/E and emailed him about his Keronix mini.. for some reason I liked the way the 8/S looked in the picture on his website). I then picked up a Nova 2, then the Nova 3, then finally he agreed to sell me EVERYTHING he had left in Dec/Data General (PDP-15, PDP-8I).. (A good 14' UHAUL truck full.) The 8/S is fully restored. I am adding the DF32 and AX08 next week to it (finally, oscilloscope video games!). The 8I was well cared for by a DEC employee. It came from McMaster Hospital (section of the university). I was amazed when I got home how many goodies were inside. DF32, Sykes 8", 24K core, and many processor peripherals, flip chip extenders, racks of spare cards plugged into new backplanes - original flip chip single sided stuff). It was modified to run TSS/8, though it did run OS/8, disk monitor, and a bunch of other stuff. I powered up the 8I and it worked perfectly..BUT HAHAHAH... Common DEC guys!! a PC0 is NOT aligned the same way as a PC04.. This PC01 was set up wrong and did not work... ... It does now :-) I hope to have the 8I running OS/8 by next week. PDP-15, serial #49 - looks like it is plug and play... filled with toys... Kevin Stumpf did an amazing job of moving this equipment safely and ensuring it was not subjected to any bad weather. Me: I am still hurt from the move (Off work).. My Internet was down for 5 days as my new toys damaged some of my Internet stuff. I got most of the equipment and docs out of our living room. I took a bunch of pictures I will have online tonight.... I still have to go in and clean out a couple of plants filled with PDP-8s/IBM before the New Year.... ugh,.... I met William Donzelli at Kevin's the last time I was there. He bought the IBM System 3... he was moving the HDs in his mini van (yikes!). It looks like McMaster bought minis and peripherals from DEC as soon as they came out (judging by the serial numbers). -----Original Message----- From: Chris Kennedy <chris(a)mainecoon.com> To: dylanb(a)sympatico.ca <dylanb(a)sympatico.ca> Date: Sunday, November 07, 1999 2:50 PM Subject: Re: Just picked up a HUGE PDP-8I and PDP-15 and ..... >Hi John, > >John B wrote: > >[details of an incredible haul, deleted] > >> Bought a large box of Nova core memory/FPU >> >> I picked up around 10 core memory planes and tons of Nova 2/3 spares. > >On behalf of the other DG collectors on the list, I can only >offer congratulations tinted with the slightest trace of envy :-) >A Nova FPU is a rare beast indeed. > >An incredible find, and a job well done. > >Best regards, >Chris > >-- >Chris Kennedy >chris(a)mainecoon.com >http://www.mainecoon.com >

FS or Trade in Socal: Vector Graphic / COMPAL System

I have a Vector Graphic "COMPAL" system (I guess they merged?) built into a Soroc-looking terminal. It has a Z80, Flashwriter, disk controller, PIO/SIO, and 64K Ram cards, but no floppy. Boots to ROM monitor. Keyboard and is in excellent condition, case cosmetics good. I acquired in my quest for a Soroc or LSI terminal, not knowing it was S-100. Now that I have my new (beige, ugh) ADM-3a, there is no more room at the counter for Compal. $100 OBO, or trade, will deliver in greater LA county area. Eliot

Computers and other hardware containing the 8008 microprocessor

Well . . . one version of the story, according to Adam Osborne, in his book (3-volume set) on microcomputers, was that Datapoint paid for the development of the 8008 for use in this jewel, then concluded that it wasn't fast enough, so now Intel had a paid-for 8-bit version of their 4004, which Osborned didn't say was what this was, but one might see a connection, nonetheless.

RT11 V5.7 + RA92 = ?

by truthanl＠oclc.org

-----Original Message----- From: Megan [mailto:mbg@world.std.com] Sent: Tuesday, November 09, 1999 10:24 PM To: Discussion re-collecting of classic computers Subject: Re: RT11 V5.7 + RA92 = ? >for a nice writeup of how the rules work). Unfortunately the RT-11 >developers chose to ignore these rules in picking their "default" second >CSR for RT-11, but of course you could choose to follow these rules >by ignoring the SYSGEN-suggested secondary (and tertiary and whatever >comes after) DU CSR's. Okay, as one of the developers involved with RT-11 at the time the DU handler was first developed after we actually got some prototype MSCP controllers, I have to respond... At the time we got the controllers, the primary address had already been defined, but the secondary and subsequent addresses were assumed to be allocated out of the floating CSR and floating vector areas. It wasn't until some later time that it was decided that the secondary and subsequent addresses were to be fixed and had a certain algorithm for determining. By that time, SYSGEN had already been modified. It was decided that 1) for backwards compatibility and 2) since the addresses can be changed with SET CSRn and VECn, SYSGEN wouldn't be changed. We didn't ignore the defaults, there were none at the time to ignore. Finally, there is the problem of the SBC-11/21[+], where the 'standard' MSCP address is actually in a pre-allocated area, so it has to be located elsewhere (176150)...

Convergent Technologies

by xds_sigma7＠hotmail.com

Mike, The Convergent machines did indeed run an OS called CTOS, though usually they weren't seen as Convergent machines. After Sperry-Univac and Burroughs merged into Unisys in 1986, they bought Convergent and continued selling the machines. The ones labeled Convergent ran CTOS, while others were labeled Burroughs and ran BTOS, which was really the same darn thing. However, these machines were OEMed very frequently, which is why I say it's unusual to see them labeled as Convergent. Those early machines were termed "Miniframes" , i.e. small mainframes. Later on, Convergent became one of the billions of clone PC makers, which didn't last long, and then Unisys discontinued use of the brand name. I have no clue what kind of CPU the things have, but if you want to get rid of them... ;p Anyways, I hope my little rant was at least somewhat informative.

RA81 questions.

by DSEAGRAV＠toad.xkl.com

Well, since the RA92 is OOC until I figure out how to kludge a fix, I guess i get to either go back to the RA81 or give up. (I have no other disks.) Anyway, when I last left it, the RA81 was complaining of seek errors, the panel lights had all burned out, and it was making scary noises. If I reformat the drive (Will RT11 do this?) will it rewrite the positioner information, or is that permanently written from the factory? The RA81 is really really heavy, and sucks a lot of amps, and I really don't know if it'll fit in the cabinet, so I really don't want to try playing with it unless it's saveable. So, questions are, is there any way to fix the disk short of a new HDA, can I replace the panel lights with LEDs, and can RT-11 format it? -------

Looking for old equipment -- please help!

by ndiablo＠diablonet.net

Hi! I've been collecting older equipment for a few years now, but i've only recently found out about this list. It looks like a great resource, and I was thinking it'd probably be a good place to ask the question: "Does anybody know of anywhere in southwest Michigan where one can find older surplus minicomputer and workstation equipment?" I've been able to aquire a fair amount of interesting stuff from the local university, but it's been slow going and parts are hard to get. I've seen postings to lists numerous times about people giving machines away in places like Texas and the East Coast, but never anything in this general area.. i'm guessing there isnt quite as much of a glut of equipment in the area, but maybe i'm just not looking in the right places! I'd really appreciate any bones anybody could throw me :) Thanks, -Netdiablo (root(a)diablonet.net)

Ebay reaches new low

by helicopterman＠webtv.net

gentlemen, the featureless panels are definitely from a Univac file 0 computer and even though they were commercially available in large numbers i doubt you have a piece of one. if you do not have a piece i will be glad to have your bid on my ebay offerings. how can you blame ebay for my ads? do you think the "pieces" would keep selling if the bidders were not satisfied? i am not the person who was selling the system 360 pieces, but sounds like he had a good deal too:)) a side note to mrbill. i took a look at your pages and they are complex and beautiful BUT you have a large number of links on the sun page all highlighted together. i know you will want to fix that. i do not intend to start a war with this letter, just to let you know my position and that you have hurt my feelings:(( "pathetic" ed =====Ed

more junk

by lemay＠cs.umn.edu

Well, my local campus computer repair shop called, asking if i wanted some junk they had. I picked up a trs80 model 1 (looks like I need to find a cassette player), a apple ][ plus with various mods installed and a analog/digital board, and a compaq portable III. Not bad for walking 2.5 blocks from my office. The NCR i mentioned earlier was too heavy, 80 pounds or so, so i left it. The apple ][ plus has, among other mods, a modification near the keyboard and speaker. A raised board with 2 IC's and a socket, its connected to one of the IC sockets on the main board, plus it has a 4 wire cable with connector. For some reason this is not plugged in. Am I correct it guessing this might be a lowercase modification, and that its unplugged to restore normal operation? any idea what the correct way to plug the connector in is? It looks like i could plug it in backwards as well as the normal way, so I have a 50/50 chance of making a major mistake... -Lawrence LeMay

Ed's response [WAS: Ebay reaches new low]

by mgregory＠vantageresearch.com

Ed, since I started this thread, maybe I can respond to some of your points. I don't blame e-bay or you for running the ads (it's a free continent), but I think you've crossed a line of common sense or fair business practice. In short, my objections to your ads are as follows: 1) You're selling such tiny pieces that they'd be easy to fake 2) Even as collectibles, they're not very interesting, and 3) I'd prefer to preserve old computers, not cut them up for scrap. Sorry for hurting your feelings, but consider: There are a lot of scammers out there - in the art and antiques world, fakes and reproductions abound. Old and historic computers are starting to attract serious money, so the incentive to create computer fakes is growing. To be blunt, you carve your scrap into such small pieces that I could saw up an old file cabinet or raid my spares box and I could make pieces indistinguishable from what you're selling. You don't even have any pictures of the parts in place before you carved up the machine to act as a "provenance" - the bills of sale just prove that you had a Univac at one time. Please note, I'm not accusing you of lying or faking anything - I'm just saying that it would be easy to produce such fakes, so "buyer beware". And, even as collectibles, I don't feel that what you're selling is not very interesting. Old vacuum tubes, circuit boards, and hard drive platters/innards at least have some visual interest. If you can sell 6" x 10" pieces of painted metal as historic computer collectibles, you're a heck of a salesman. Most importantly, the members of this list are generally people who want to preserve/restore old computers in working condition. We are always on the prowl for rare or unusual computers and spare parts. Increasingly, some older computers are being carved up to produce collectibles like the ones you sell. A concrete example is core memory planes from PDP-8 computers; some people rip these out of old 8s and hang them on the wall as art - most of us would prefer to preserve the working machine. Just my thoughts.

new additions (OT) Autoclaves

by mmcfadden＠cmh.edu

A pressure cooker is basically an autoclave. When canning vegetables the heat and pressure destroy any pathogens. Autoclaving is used to sterilize instruments and medical devices. The instruments are usually enclosed in a porous package that allows the moisture into the package and keeps any contaminants out. The high pressure with moisture is designed to activate and destroy any bacterial spores that may be in the package. There is usually a heat activated strip in the tape on the package that changes from invisible to brown and says "sterile". Any device that could be damaged by heat such as a plastic catheter can be "cold sterilized" by ethylene oxide gas. This is not as effective as the heat/moisture method. Also used on medical waste to reduce the chances of spread of disease. Many medical devices are now sterilized by ionizing radiation, gamma particles, a radiation source is exposed next to cases of the products and hopefully "zaps" the DNA in any contaminants. Another use of autoclaves is to laminate layers of carbon fiber cloth to create composite aircraft and machine parts. The heat and pressure cause the bonding agents, such as epoxy, to bind the layers together. I think the B2 and F117 skins are created by this process. More than anyone wants to know about autoclaves.

Unidentified terminal with built in modem

by mmcfadden＠cmh.edu

As I was digging through a box of computer surplus I came across the following: Dun/brown colored terminal device with what looks like a 3" high display with a pair of foam cups, acoustic modem, on the back. Full size keyboard. It looks like a calculator except for the qwerty keyboard and the modem. Labeled as follows Computer Devices series 2000 I've searched both altavista, google, and yahoo and I haven't found anything close. Maybe I need to examine it more closely. Does anybody have any ideas? Thanks Mike

Needed....

by black＠gco.apana.org.au

Hopefully someone here can help...... I'm after a keyboard for a PET 2001 - the original chiclet style, screen printed job. I've got a working 2001, but the keyboard has been more or less destroyed to the point where it is beyond repair. So if someone has a broken PET with a functional keyboard, I'd be really, really, really appreciative if they would part with it..... Thanks, Lance PS: I'm in OZ, but on such a small component, I'm willing to take it from anywhere.

Apple ii-c questions

by edick＠idcomm.com

I've had this more or less useless Apple-iic sitting about, always suspecting it could be used for something, and I've had a couple of ideas, but I'm curious whether it uses the same DOS as and has other characteristics similar to the Apple][+. The joystick port seemingly has a few bits of input and the printer port has a few bits of output. It would be amusing to do something useful with this thing. What are the port locations for its internally packaged I/O? Are there ways of expanding the I/O without slowing down for serial I/O? If I open the box, what will I find? Anything capable of handling, say, a PIA? Dick

Sure, this is done fairly easily. You have to modify not only the SET overlay usage inside the DU handler, but also the parts of RESORC.SAV responsible for SHOW DEV:DU. (Working from memory, the relevant parts are in RESDEV.MAC on the source kit - I was fooling around with this earlier this year to add multi-CSR display capability.) The real question is, will I ever have so much RT-11 software/data that I need access to more than 8 Gbytes? I've got a wall of 8" floppies here, over 7000 floppies in total, but all 7000 floppies together (even assuming double density) are only 3.5 Gbytes! (And less than half of those 8" floppies are RT-11 stuff in the first place - the rest being WPS/8 and CP/M stuff.) >Tim, do you have the search algorithm for alternate CSR addresses >when the standard CSR DU MSCP address of 172150 is either >not available at all or is a removable floppy with no media present? The "DEC standard" way of determining alternate CSR's is to follow the autoconfigure rules (see http://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/hardwar… for a nice writeup of how the rules work). Unfortunately the RT-11 developers chose to ignore these rules in picking their "default" second CSR for RT-11, but of course you could choose to follow these rules by ignoring the SYSGEN-suggested secondary (and tertiary and whatever comes after) DU CSR's. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Anyone got a spare RA92 frontpanel? (Every fscking time...)

by DSEAGRAV＠toad.xkl.com

I swear, (Boy do I swear!) every time I put my hands on something, every time I think I got something figured out... My RA92's front panel appears to have been roached. I don't know how or why. Upon dragging (Not literally) the thing up to the 5th floor from the basement, and applying power (Not connected to the controller), the display (Which normally says WAIT for a few seconds) is blank. Funny. So I screwed with it for awhile. If I jiggle it around, I can get garbage (usually) but after about a half hour of screwing around, I pulled the drive's front plate off, and looked around the insides. The logic inside and the cables are all in immaculate shape. They look brand new. So I reassembled the drive and pulled the front panel apart. It looks OK too. So I put the drive back together. Argued with it another 45 minutes. Finally, I got lucky and got a spot where, for about 5 minutes, I could work the panel. The FAULT light was lit, the error code was "E B4". I tried spinning the drive up, and then the panel glitched and reset. The drive spun up and checked (and it sounded OK), but then it spun down and faulted E B4 again (it must have realized the panel is screwed.) The drive shows no inclination of working without it. Moving the panel around makes the panel flash random lights and display garbage, so I think the panel's bad. Can anyone prove/disprove this? I have no docs so I dunno what the error code means. I did get the E B4 several times, so I think that's good data. It might not be. -------

Okay, as one of the developers involved with RT-11 at the time the DU handler was first developed after we actually got some prototype MSCP controllers, I have to respond... At the time we got the controllers, the primary address had already been defined, but the secondary and subsequent addresses were assumed to be allocated out of the floating CSR and floating vector areas. It wasn't until some later time that it was decided that the secondary and subsequent addresses were to be fixed and had a certain algorithm for determining. By that time, SYSGEN had already been modified. It was decided that 1) for backwards compatibility and 2) since the addresses can be changed with SET CSRn and VECn, SYSGEN wouldn't be changed. We didn't ignore the defaults, there were none at the time to ignore. Finally, there is the problem of the SBC-11/21[+], where the 'standard' MSCP address is actually in a pre-allocated area, so it has to be located elsewhere (176150)...

How you keep track of what's >> in all 256 partitions is your business :-). >And How you keep track of what's in all 256 partitions ? Admittedly, keeping track of all those partitions can be dizzying sometimes. There are some handy "tricks" (I put that in quotes since many of us RT-11 oldtimers have been doing these for years, and these are all documented tools, but sometimes used for other purposes than to aid my failing memory) for keeping volumes straight: 1. Use the /VOL qualifier when INITting the volume to put something descriptive there. For example: RT-11FB V05.07 .create junk.dsk[100] .mou ld4 junk.dsk .init ld4:/vol LD4:/Initialize; Are you sure? Y Volume ID? Descriptive Owner? Information 2. If you've done (1) above, then you can use the /VOL qualifier on DIR to remind yourself what's on that partition: .dir/vol ld4: 09-Nov-1999 Volume ID: Descriptive Owner : Information 0 Files, 0 Blocks 92 Free blocks 3. Use logical names to identify the volumes, and a command procedure to define them all. (There is no real equivalent to a logical name in many modern OS's, including Unix, unfortunately. A logical is kinda/sorta like a Unix mount point, but a logical is far better because you can redefine as you find handy.) With RT-11 you only get 3-character logical names, but that's a start: .ASS INF LD4 .ASS SRC DU3 .ASS BIN DU1 etc. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Digital PC350

by awcl＠awcoldstream.com

Hi All, Ok as Tony said this is Digital Professional workstation. The sceen lights with small square and I can see horizontal traces, I guess fly back. Sorry It is not the vertical scan. When I got it started fine with some os (I have not seen PDP before) with five or six menus on it. It was so dusty, I clean the dust and now it starts with blank dispay (with horizontal fly back lines) But if I hit keys, I could hear beeps so I guess system works fine. I just broke the display part or cable. This is what I see. Monitor - VR201 - with 15pin male connector and RJ-11 connector for the key board. Red lights on the back 1 & 2 ON. Geen light "DC" on. on the card slots right to left 1--empty 2--empty 3--000034 4--001002 5--002004-may be floppy disk controller 6--000401-cpu and hard drive controller Thank you in advance for your thoughts Anil

Needed, Memory chip info for a Compaq

by mdalene＠home.ctol.net

I am aware that this list covers Older systems than Compaq. From what I can see from reading this list.. someone might have an answer. I have a Compaq Despro 386n. Currently it has 4mb of ram. I am painfully running Slackware 3.1 on it. Does anyone know what kind of Memory this machine is using? From what I can see, it has two Simm modules that appear to be 72 pin. There is memory chips on both sides of these. Does standard Simms of the 72pin variety have memory chips on both sides of the simm? If these ARE standard, does anyone have two 8mb ones? I want to put 16mb of ram on the Deskpro as 4mb stinks! The Compaq only can hold two of them unless you have the special Compaq memory expander board. If these are specialized. again who has them inexpensivly? Please respond either via the list or priate email to my address above.

Is this a modem?

We used to use it for our DEC Qbus and VAXBI bisync/SNA protocol emulator boards... very fancy stuff for classic equipment. A few gotchas like you can't access the registers in back-to-back I/O instructions... there's some internal delays especially on the 4Mhz parts when used with an 8Mhz MC68K CPU.

MOP bootable XXDP?

Is there a diagnostic image that is bootable via MOP on a VAX that does diagnostics? I'm interested in testing some Q-bus boards of unknown integrity and this would seem to be one way to do it. I have the capability to write a bootable MOP image but before I write my own diagnostics I thought I'd see what else had been done. --Chuck

Differences Between CompacTape I, II, III

by jhfine＠idirect.com

Does anyone know what are the magnetic strength of the different media inside DLT type tapes? I am trying to understand what are the differences between a CompacTape CompacTape II CompacTape III also know as a DLT tape I can see any physical difference except for the color of the name. I assume that the tape media have different magnetic strengths. There was a recent discussion about the magnetic strength of 5 1/4" floppies - I remember that the DSDD were 300 o and the HD were 600 o. Do the different CompacTape media have the same sort of differences. I did look up the quantum.com web site and it seems to state that the CompacTape III are metal tapes.

Well... unless the keyboard has been vacuum sealed for the last 20 years, I can pretty much say with certainty that the contact pads in the mechanism have deterioriated. They can be repaired however. (I've done a lot of them) I have replacement contact kits available as well as keyboard rebuild services. Details are available on my web site on the 'Parts/Objects/Services' page... with the contacts gone, the keyboard will appear to be totally dead in most cases, although I have not seen too many serious logic failures on them.

I had it misterminated for a bit (the middle drive (of two) was terminated rather than the end drive). But I fixed that without any increase in performance. The format/block analysis took about 10 hours for a 600MB disk. The interleave was set to 1 but that seems pretty standard these days, should I up it to 2 or 3? or perhaps reduce it to 0? The drives are Micropolis 1568's so they're nice fast drives. How about Q-bus priority? I moved the Dilog to the slot just after the DELQA so it its CPU->DELQA->DILOG->TQK70 but that hasn't helped either. Any other suggestions or are these things just slow? --Chuck

Dear Sir, 08.11.1999 I have a notebook of a model named 486 DX. I have a great difficulty with it. In its bios, there is a code number. I can't decode it. The bios number of the notebook is Amibios (c) 1992 American Megatrends PM BIOS 050042. (7500 E P10 092894) I Will be appreciated if you can send me the method that you decode your notebooks. Looking forward to hearing from you. Ihsan ?arikci E-Mail Adress: icarikci(a)atauni.edu.tr
