vax/vms file archival ideas and suggestions

by trash3＠splab.cas.neu.edu

Hi all, I must be missing something, but I have not found a good way to preserve a bunch of vax/vms files. I've looked at VMSZip, Gzip, VMSTar, etc, and I must be missing something. Here is what I am trying to do: Before my vax finally dies, I want to take the hundred or so TK50s I have and restore them to the hard drive and then move them to PC-land for long term storage. This is halfway done with the tapes that are easily readable. I now have a bunch of directories, one for each tape, with files in them on the VAX. So the tree is only two levels deep on the vax. The files are pretty mixed: backup files, savesets, distributions, text files, etc. Right now the files amount to about 2Gb. Now, the environment is: VAX 3100-30 with SCSI external. THis is where I hooked up the TK70 (TZ30?) to read the tapes. I have network access and can get to it via FTP and TELNET from elsewhere, namely my PC. I also have a bunch of different SCSI tape drives, 8mm, 4mm, 9 track, etc. So, I could transfer all the files if I could containerize (zip) them. Do I try to Zip them somehow (what program) and FTP them, or do I just write them to duplicate disks/tapes and throw them on a shelf, hoping I have a machine to read them in the future? I'm usually pretty good with this stuff, having been around the VMS world for a few decades, but I just have this memory block, or the blinders are on. Any suggestions? Thanks Joe Heck

Stan Veit's History of the Personal Computer Audio Book Podcast

by david＠classiccomputing.com

Hi everyone, I would like to announce my newest project, a weekly podcast of an excellent book on computer history, in audio format. I have received permission from the author, Stan Veit, and his publisher to pursue this. The first installment is now ready. My podcasts are in m4a format, but there is a zipped mp3 version of this one that can be downloaded from my web site. Though I am not a professional broadcaster, announcer or reader, I have worked hard to make this production as professional as possible. Please give it a listen if you have a chance. The publisher hopes to put out a new edition of the book soon. This original edition was published in 1993. I have personally sold 250+ copies of it over the years, as I am a big fan and I have met Stan personally. Stan opened the first personal computer store on the east coast in New York City, which was only the second one in the world. He was also the founding Editor-In-Chief of Computer Shopper magazine. Thanks very much, David David Greelish classiccomputing.com The Classic Computing Podcast Home of Computer History Nostalgia Stan Veit's History of the Personal Computer Audio Book Podcast

Wow; $192 for a 5.25" floppy disk drive

by Watzman＠neo.rr.com

Re: " Hmmm, I've still got a few 3.5' BP drives in original shrinkwrap..." No go. There is no demand for either the 3.5" drives or the CD drives. Only the 5.25" drives ($192 was high, but these usually go for about $100). Reason: There ARE USB 3.5" floppy drives, and USB external CD drives. But, at present, if you need to read a 5.25" floppy on a PC, there is no easy way to do it. Modern motherboards no longer even support two floppy drives [at all, of any kind]. And laptops? Forget it. We NEED a USB 5.25" (and I'd argue even 8") drive interface device. It should support both 360k and 1.2MB 5.15" drives, and perhaps 8" drives as well. At present, the old parallel port 5.25" drives are the only option for many people. So they will fetch absurd prices. I have a 3.5" backpack also. And a backpack tape drive, which used a floppy interface. I'd love to convert either/both to a 5.25" drive if you know how.

Somewhat OT: Wireless MIDI

by cclist＠sydex.com

The talk about RS-232C reminded me of another simple interface that's been around for awhile--MIDI. I hate MIDI cables--I mean I REALLY hate them. I trip over them, they get tangled up in my chair and I'm afraid the dog will eat them. I've seen a couple of wireless MIDI adaptors, but since they're low-volume items, they're freakishly expensive. Does anyone have any ideas or experience with a low-budget wireless MIDI setup? Cheers, Chuck

IIci cache cards?

by spectre＠floodgap.com

Anyone got any IIci cache cards they'd be willing to consider parting with? My indefatigable IIci (which has powered DNS, printer services and network power services to my apartment network for going on six years now) has burned through another one, evidenced by 1) a kernel panic in NetBSD 2) the Chimes of Death 3) the Chimes of Death going away replaced by normal booting when I replaced the cache card. It seems I go through one around every two years, so it was due to eat another one, I guess. The 32K variant will do nicely. Please respond offlist, and thanks. -- --------------------------------- personal: http://www.armory.com/~spectre/ --- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- When people get acupuncture, do voodoo dolls die? --------------------------

PDT-11/150 down

by ssj152＠charter.net

Well, this is my first post to the list in quite a while; most of you may not even remember me... but I have been lurking. Now I have a problem I need help with. I have a PDT-11/150HC, the dual drive model with 32KW and the 3 extra serial ports. It had been working fine, up through last year, when I stored it. I was working on another project, building a PDP-11/53 from a DECServer 550 (like Jonathan Engdahl's) when I needed to copy some floppies. I brought out the trusty old PDT, and of course, it wouldn't work. I am using a VT420 with DECConnect wire and shells to talk to the PDT. The VT and wires are all known good, tested with other equipment. What happens is that when I turn the PDT on and type the 2 "@" characters to set the baud rate (4800), the #2 led properly goes out, the RUN led comes on, but NOTHING comes back to the terminal. Thinking that I needed a NULL MODEM in the cable, I put a MMJ crossover connector block between the terminal and the PDT. Strangely, I had exactly the same results - nothing out on the monitor - with TX and RX swapped how the heck does this happen? As I recall, the usual response is something like "Press B to Boot". In any event, pressing "B" does nothing either. I have performed the self test with the lid off and modules elevated and the result was that the first 4 LED's on the Intelligence Module came on. This is result #17, indicating that either the DISK Controller Module or Cable G1 has failed and need to be replaced - impossible, at least in the case of the Disk Module. Besides, what does this have to do with no response on the terminal? My next step is to test the power supply and trace power to the various modules, as per the Mini-Maintenance manual. I'm hoping that someone on the list is more familiar with the PDT and can offer useful suggestions that might shorten an exhaustive troubleshooting effort - I'm not really up to it. I have as resources 3 books, 1) The PDT 11/150 User Guide (EK-PT150UG-001), 2) The PDT 11/150 Installation Guide (EK-PT150-IN-002), and 3) The PDT 11/150 Mini-Maintenance Hardware Guide (EK-PT150-J1-002). I would very much like to get a copy of EK-PT150-TM, the Technical manual, in print or PDF format. I also have the usual DVM, a Tektronix 2215 dual channel scope, and the memories of being an electronics technician (with a radiotelephone license) during my late 20's, a lifetime ago. I spent the last 20 years of my so-called career as a systems programmer and am now retired. Can someone that knows about the PDT assist me? All useful input appreciated!

Experience with cartridge archival?

by trixter＠oldskool.org

A mutual acquaintance of mine is trying to write a thesis and needs a little help. He writes: "The project that I am working on is for my Masters in Library Information Science degree with a focus on Archiving. For my paper I have to write a 10 to 12 page paper on a subject that involves the preservation of something that has archival significance. So I decided to do it on video games and what steps are being taken to preserve them on the media that they were originally written on such as Atari and Nintendo cartridges some of which are degrading significantly and no longer work on the game systems they were designed for." If anyone has any help or leads for him, or any experience archiving ROMs/cartridges that may degrade over time and how to properly preserve them, please drop him a line at "andrew.pacilli at simmons.edu".

Info needed on some 1980s-era Intel parts

by ethan.dicks＠gmail.com

I've been trying to puzzle out a board in front of me, loaded with Intel chips. The CPU on it is a 16MHz 80186 - it appears to be an interface peripheral board for some Astro-Med product. Externally, it has a serial port and a GPIB port. What's strange to me is that I can't identify the parts that appear to be the GPIB buffers - a pair of 28-pin Intel D8293s. There's also a P82C08, which I can't find any hard info on. So... does anyone recognize the Intel part numbers P82C08 or D8293 (yes, I know the P is plastic and the D is ceramic; it's the parts themselves I'm curious about). Thanks, -ethan

Honeywell 7-track tape drive - who has EVER seen this?

by hachti＠hachti.de

Hi folks, please take a look at this picture: http://h316.hachti.de?gallery/tape_drive2/dscn1704_1024.jpg More can be found here: http://h316.hachti.de?gallery/tape_drive/ http://h316.hachti.de?gallery/tape_drive2/ Who has ever seen/used/heard about/repaired this kind (similar is ok, too!) of tape drive? Doesn't matter if in a museum, private collection, basement, scrapyard, heaven or hell. Doesn't matter if long time ago or today - let me know! Please contact me if you have seen this kind of machine before. I am looking for EVERY trace of these machines! Every hint is appreciated. Also things like "I have seen such a unit 25 years ago in a factory for women's underwear which is closed since 15 years" are important. I hope to find still some traces. These machines were very heavy so there's a real chance that there are still some of them standing around forgotten. That's a Honeywell 4210 7-track tape drive. Once I've ruined three friends' backs with helping me to get it into my first floor collection room. And now I've got the problem that most of the electronics are missing. I don't have a solution yet. I don't know where to start. And I have no spares. But some documentation. I know only one thing: I want to and will bring it back to work! But it would be better and easier to find spare cards or a second unit. It would also be great to get some pieces (easily exchangeable parts) for some limited time - just to check the rest. So please try to remember and contact me. And yes, I have asked this before. Will do that again and again from time to time. Any luck with that could save me weeks of work (which I actually cannot afford at the moment). Thanks a lot! Best wishes, Philipp :-) -- You have to reboot your computer after powerfail?

Pertec / 9 track cable question

by fireflyst＠earthlink.net

Hi all, I've had a malfuntioning magtape setup on my 11/23+ for some time and I'm wondering, is it the card, cabling, or drive? here's what I've got: Overland OD3201 magtape drive (works fine when the parallel port connection is used when connected to a PC) Dilog DQ132 pertec tape controller Two straight-through ribbon cables, 50 pin IDC on one end, 50 pin cardedge on the other. J1 on card is cabled to P1 on drive. J2 on card is cabled to P2 on drive. When I try to perform an operation on the tape drive, it times out The drive does spin a bit first. Rewind operations work correctly. It seems to do this no matter how I have the card configured. Are these cables really supposed to be straight through, or what am I missing? Any help would be appreciated. Thanks! Julian

new part-faulty RAM chips?

by julesrichardsonuk＠yahoo.co.uk

Does anyone know if the Sinclair Spectrum ever made use of RAM chips that were known to be part-faulty as-new? This was just asked over on another mailing list... I recall discussions about such chips in the past on here, where manufacturers would sell 'faulty' RAM to vendors at lower cost where only half of the address map could store data reliably. However, I'm sure that was late 70s or so, not the early 80s when the Spectrum existed; by then I would have thought that the manufacturers would have had the reliability issues sorted out and would simply dump faulty stock? Anyone able to confirm? cheers Jules -- If you've ever wondered how you get triangles from a cow You need buttermilk and cheese, and an equilateral chainsaw

Classic ports missing on modern machines (was Re: PDT-11/150 down)

That's true at my place, too, but I have plenty of uses for a parallel port on a machine that has nothing to do with printing and I'm not happy to see that port go on modern machines. (examples - parallel-wired LCDs on LCDproc, analog meters, etc). Likewise, I lament the loss of the serial port on modern laptops (still on desktops so far). I probably have some serial device plugged into my primary desktop 90% of the time. -ethan

ID an 8" disk format

by kelly＠catcorner.org

I've started to read some of the disks. Does anyone recognize the following strings? I'm trying to ID the source OS for the following (it is the ROM source for a Panasonic KX-D4911 terminal). Here are some of the strings: IN-III MACRO ASMB. (Z80.ZILOG) VER. 1-01 830131 DATE 60. 1.10 PAGE 1 SYSTEM ANALYZER IN-III VER. 2-2 ISIS IN-IIIDIN6301 DINZ80B This was a pretty standard DS/DD 8" disk that read right in using a catweasel and also with imagedisk. I think it might have been an Intellec-III, but that is based on the repeated appearance of ISIS, and the fact that it is ROM source. Any clues? Thanks, Kelly

DEC-20, VAX-8600, PDP-11/70 and Update computer club...

by bqt＠softjar.se

Since we've been mentioned, I might as well fill in the blanks and correct the errors. Yes, Update, located in Uppsala, Sweden, have two DEC-2060 machines. Both were operational when we stopped running them. The last we stopped in 1993 or 1994 (don't remember for sure now). I believe we could atleast get one of them back into running shape if we just had space. But at the moment we don't. And this all is in the hands of Uppsala University. The machines are Aida.Update.UU.SE and Carmen.Update.UU.SE. (Not sure if the DNS is being maintaned for these right now.) While we're at it, we also have one VAX-8650, which is operational. We only need to turn the key, and it will boot. Normally we boot NetBSD on it, but we can also boot it into VMS or Ultrix. (Krille.Update.UU.SE) And someone also mentioned DECsystem-570, which is a PDP-11/70 in a corporate cabinet. We have one 11/70 (in the old style) which also is just a turn of a key away from running. (Magica.Update.UU.SE). However, we do not have any KS-10 machines. I believe Stacken (the computer club at the Royal Institute of Technology in Stockholm, Sweden) have both KS-10 and KL-10 machine still around. In the past they also had a KA-10 machine, which might still be around. And I know of another private individual who have a working KI-10 machine in Stockholm. That is actually a tri-CPU KI-10. As for periperials, we have: RP07 (2) RP06 (4) TU77 (2) TU78 (1) And of course we have MSCP disks and HSCs for the VAXen and PDP-11s. (Oh, and we have another 11/70 and 8650 in storage) Some images and pictures (rather incomplete) can be found at: http://www.update.uu.se/~bqt/computers.html There should be some somewhere on Updates official pages as well, but I can't find any right now...

Semi-OT: "Inkjet Printable" CD/DVD blanks

by healyzh＠aracnet.com

Strange question, but it directly relates to preservation of classic computer data. My perfered brand of CD/DVD blanks are the Verbatim DataLifePlus disks. There is no doubt in my mind that these disks have a good long lifespan (though I do need to see about doing a data refresh on some). However, due to their cost, they are no longer that easy to obtain. One source I've been considering using seems to only sell the ones that are "InkJet Printer" ready. I have no desire to use an inkjet printer to do this, does anyone know how safe is it to use a standard "CD Marker" on these blanks? It seems to me that these might actually be easier to write on, and be able to read what you've written than most I've been using. Zane

At least it does have a header for a serial port on the Motherboard, I'll just have to find a port to connect to it (as that didn't come with the board). Oh, and the board does have a Parallel port." Let me guess: Asus P5B? I chose a Gigabyte GA-965P-DS3 instead of the P5B primarily for just that reason (the boards themselves are nearly identical). The P5B uses one of the two "standard" cables. Look on alt.comp.periphs.mainboard.asus about 60 days ago and you will find a discussion of this, along with the specs for the cable (there are two "standards" for this cable, different and incompatible, so you need to get the right one). I can't believe Asus' stupidity in not putting the DB-9 on the I/O shield OR at least in not including the cable to the header.

SDS/XDS-940 (900 series)

by kahrs＠caip.rutgers.edu

I admit, I cut my teeth on that machine and so I continue to ask around for remaining tidbits. My friends at Tymshare don't have bits apparently and I wasn't around when the 940s went out the back door. Al K. has my copy of the monitor (kernel) listing; that could be OCR'ed but what about the executive and all the other stuff? But the real question is: What does MUL =12525253B do?

8" disk archive

by aek＠bitsavers.org

> If anyone has any comments, please speak up. If the contents can be identified, consider some form of checksum per file. Eventually, as multiple copies of the same discs are found from different sources you can verify file integrity. If they are original distrib discs, checksums of the entire volume can be used for disc integrity (and for simple checks for viruses on newer media)

Serial devices, analyzers, etc (was Re: PDT-11/150 down)

If I understand their business model, they charged a premium, but what the customer gained was a single place to go (one catalog, one vendor to send POs to, etc), and some "big name" reassurance. In my experience, large companies deal with small companies poorly or not at all. If a small company comes up with a nice comms-related widget, they can try to sell it themselves with potentially mixed success, or sell quantities in black enclosures through Black Box and get instant exposure when the next catalog comes out. > I actually picked up an older but practically new serial analyzer on eBay > this last month for about $10.

We had several analyzers (HP) and BERT boxes (bit error-rate tester?) when I worked at Software Results making sync comms hardware - fortunately I got to take my pick when the doors closed. I still have a bunch of that kit, and it's still useful since most of the gear does async as well as sync. If your analyzer only goes to 38Kbps, it's probably async only. Sync stuff I've worked with, tended to go up to 64Kbps or even 128Kbps (if it wasn't designed for T1-like connections). -ethan

Do you have any ideas what you will call the site with the archive? Perhaps you should announce a beta version (when it's up and running) for us to test?

the last MIT ITS dec-20 (AI.MIT.EDU) is up for sale

by akb+lists.cctalk＠mirror.to

Chris Zach needs the space, so he's selling off his KS-10 (2020) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=011&item=320038687685 This machine was the last host to be named AI.MIT.EDU that ran ITS, and probably the last running DEC 10 or 20 at MIT (though that might have been MC). It comes with an ITS disk pack (and a drive). Might also have TOPS-20. Bidding is at $2k so far. --akb ps: AI, MC, and the hulk of a third 2020 which I think was BLT (Brave Little Toaster) were part of extensive hacker rescue efforts in the early 90s. They were schlepped out of MIT, sat at digex.net for a while until the VC-installed managers almost junked them, then CZ rescued them and has cared for them since. (I'm not sure what he's done with MC, BLT was mostly just the chassis and prolly got scrapped). In the auction photos, those small red tags next to the bar codes are the MIT "deactivated property" tags.

Pinball machine available

by mouse＠Rodents.Montreal.QC.CA

Okay, it's not quite typical fodder for here, but it seems to me to be close enough to count as on-topic. Two friends of mine (okay, a friend and an acquaintance) have a pinball machine. But it's sitting in a barn and they'd like to get it in the hands of someone who'll use/appreciate it before winter hits (it's been there for a few months, but this would be its first winter). I've never seen it myself. Here's what I've been told: It's a "Data East Robocop" machine. No date apparent to the person who looked (whom I'd primed to look for a date). One piece of glass is shattered; from the description, it sounds to me like the backglass - the vertical glass with artwork in front of the scoring and status displays at the back of the machine. I'm told it's also functionally broken in some minor way, but the person who characterized the malfunction as "minor" is no pinball expert, so I have no idea how accurate the characterization is. I also have no better description of the malfunction. The machine is near Ottawa (Ontario, Canada). So, my questions: (1) is it worth anything in its current shape, or does the damage (and/or maltreatment) cut its value to the point where it's comparable to the cost of hauling it away? (2) anyone have more specific relevant questions that can be answered by someone not versed in pinball machines or electromech devices in general? Oh, and (3) anyone want it? :-) (I'd be tempted myself except I have no place to put it.) /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

In fact before BSD, there was project Genie which made an SDS 930 into an SDS 940 (added paging hardware) and made up a timesharing system. It was the basis of the Tymshare corporation which was formed in the 60's. The machine had (IIRC) 64k of 24 bit words, paged in chunks of 4k words. The technique used what they called "relabeling registers" on the upper 8 bits of the memory address. The software had all sorts of things, including 'forks'. All before Unix (1969). Quite a system for its day. It was the competition to the GE 235 (Later 635) machines that started at Dartmouth. In the early 70's they had a whole bunch of machines in Cupertino under one roof. As for strings: They packed 3 to a word (usually). Trivia: 'BRS 131B' was the system call to crash the system.

machine emulation

and was I tempted. O was I tempted. I could have been o so creative with the spelling of the first word in the subject line... I guess the question on many peep's mind is whether a utilization of virtual-8086 mode could be used to creative an emulation of something peecee-like (Tandy 2000 maybe?). I need to do some reading.

Hi Jim, What a coincidence -- we just got a lengthy email from Wayne Farmer in the ibm1130.org guestbook, who also talked about working with the that same Meta IV (production serial #1 in fact), at UC San Diego, and he described working with these very microcode ROMs. Hey, are you planning on coming to the Vintage Computer Festival in Mountain View, CA in November? If you are it would be great if you could bring this microcode board with you to show off at the IBM 1130 party which will be held Saturday evening during the VCF. Brian

Software Archaeology (was Oregon Software Pascal/2 (24 bit words))

by aek＠bitsavers.org

> As you're more aware than (probably) anyone at > this point, software archaeology is exceedingly difficult. The thing to do is just keep asking anyone who was connected to the industry if they know folks like field serivce techs that were pack rats. The companies themselves either deliberately threw it out so that they wouldn't have to support it, or the physical assets were tossed out when companies were sold. The fact that the SDS 900 series library survived mostly in tact after being given away by Honeywell in 1982 gives me hope that people may have similar stashes somewhere. -- Somewhat related, a CHM press release just went out with this info in it: In support of its international collection and exhibit plans, the Museum also announced that it has acquired an extensive collection totaling seven shipping containers of computing objects salvaged from a crumbling warehouse in Dortmund, Germany this month. The rescued items, along with related documents and software, will augment the Museum?s existing 80,000-object collection that will be used to populate the 2009 exhibit. The historic collection from Germany was rescued from an open-air warehouse that encompassed a physical area of about 12,000 square feet. There are 112 unique manufacturers represented, including Telefunken, Siemens, Zuse, Olivetti and Groupe Bull. European-based manufacturers account for 50% of the acquired artifacts and another 20% in documentation and software. In addition to many rare computer systems, the rescued items will deepen the Museum?s holdings of electromechanical-era objects, as well as mainframe documentation and software. -- The container with documentation and software should be getting here in about a month. From the pictures, there are some very interesting things coming. This was partly from the computer museum which closed in Achen.

Digital Systems Corporation

by jwstephens＠msm.umr.edu

I am moving stuff out of my warehouse to storage, and am finding all sorts of nifty toys. One is a rom from a pretty old mini or mainframe, which is badged Digital Systems Corporation. It is "alterable" much like I understand the 360/20's were with boards that were used to program sense arrays, and could be altered in the field to change the firmware. As I mention in the web page, I have little information on it, and retrieved it as a close friend was downsizeing his collection of stuff many years ago. I don't know that he obtained it from a working machine, but we both agreed that a packrat like me would be better suited for it than he was, as he wanted to just have less stuff. I was very fortunate to know a few that were downsizeing to me rather than the land fill (and am working with one now). Anyway, maybe someone will have some comment on the company name or logo. I apologize for the current photos, I will try to scan or get better resolution photos of the label and post it, or follow up this on the list. I get nothing on any site that is of any use, as the three words that the company chose for itself may as well be "smith" "jones" or any word with millions or billions of hits, and nothing recent other than companies in Japan and Costa Rica (both unlikely to be useful) Jim http://jwstephens.com/rom/page_01.htm

PSU Capacitors

by ohh＠drizzle.com

I've got a couple of old DEC machines which look like they could use new filter capacitors in the power supplies: I tried reforming the originals, and in some cases it worked, but there are also a few which look like they'll never see full capacity again. These are electrolytics, with 160,000mf/20v/24v surge and 57,000mf/50v/65v surge being the original values. Soooo here's my two questions: -Where would you recommend buying new ones? Anyone have a capacitor vendor they're particularly fond of (or particularly loathe)? -Does it make better sense to replace these with electrolytics, and have the same characteristics (and the same problems over time) as the originals, or is there some more modern cap-technology which would give the original's performance but with a better lifespan? I'm not up on my capacitor technology. :) Any help or suggestions would be welcome. Thanks! -O.-

Lightning Damage (was: Re: DOS answering machine ??? )

by mtapley＠swri.edu

At 12:00 -0500 10/16/06, Roy Tellason wrote: >That was my way to do dialup for a while here until it got weird after a >storm. This seems to be a recurring theme in posts here. At least here in the central US, thunderstorms are pretty predictable. I have made it SOP for over a decade now to just disconnect classic gear from the wall when one is known to be approaching. (I even have the family trained to do it if I'm not around; it helps that we and our relatives have lost several TV's, stereos, modems, etc. to lightning strikes, so it's not just a theoretical possibility.) I recommend: 1) Plug all of the classic gear into power strips or surge suppressors. Plug the surge suppressors into the wall for normal use, and shut down/unplug the surge suppressor from the wall for storms. 2) Leave commodity stuff connected, if it's convenient. DSL hubs can be disconnected from the wall (and cable or phone line!) or can be left connected, with the ethernet coming out of them disconnected for duration of the storm. Cheapo modern ink-jet printers can be left connected to the wall, but disconnected from the classic computer or classic network. Nice Laserjet 4MP printers, etc. should be disconnected from the wall. 3) Wireless, where practical, makes disconnecting the network easy. A single wireless/ethernet hub, using radio to get to the wall-connected DSL/cablemodem hub, might be a *great* way to air-gap the whole classic network. That would reduce the storm-proofing operation down to a single wall plug (for the power strip). 4) Exercise the same precautions for winter storms - power line outages/restoration of power can do unpredictable things to line voltage and frequency. 5) Do not trust surge suppressors to do the job, either on power lines or on modem/cable lines. They help, but they have limitations. Some a lot more than others. 6) For stuff that is really hard to re-boot, UPS's can help if they are big enough. Disconnect the UPS from the wall and live with the alarm until the thunder dies down (but this assumes a big battery on the UPS, which might not be realistic). I know server stuff that wants to be up 24/7 is hard to do this with, but for really classic equipment, or for anything that's used on-demand (like Roy's modem), it really seems a shame to expose it to ESD death for want of a minute's work walking around the house and pulling plugs. My worst loss so far (knock on wood) has been a Powerbook 3400 internal modem board (visible damage on the board, pictures available on request). But I've been lucky a few times.

Oregon Software Pascal/2 (24 bit words)

by aek＠bitsavers.org

> Has anyone ever found any GENIE tapes or backups? There are two sets of backups from UCB and Shell Development that have been found. The problem is there are no surviving copies of what was on the swapping drum, so building a runnable system has proven to be very difficult. The contents of the tapes need to have the personal directories expunged before they can be released. Unfortunately, the SDS software library that CHM was just given doesn't contain the system software for the 940. There is one diagnostic tape and a user utility tape. >From going through the documentation that came with the library, it looks like there was very little for the 940 inside SDS as far back as 1971.

DOS answering machine ???

by rickb＠bensene.com

> >I am looking for a DOS program to turn my computer into an answering > >machine. There was a dedicated ISA-bus card for the PC called "Watson" that did exactly that under DOS. It had a character-based user-interface. It allowed remote access to the voicemail boxes. It could also serve as a "demon dialer", intercepting touch tone signals to do speed dialing and other functions. The device had two RJ-11 jacks, one for the phone line coming into the house, and the other which fed all of the rest of the phones in the house. It could also, with optional software, be set up as a basic AVR system. It could also serve as a 1200-baud (IIRC) modem. I don't recall any FAX capabilities. I have one of these around somewhere, and even the "voicemail" software (on 5 1/4" DOS floppies), along with the documentation. I used it for quite some time on a clone "XT"-class machine utilizing a NEC-made 8088-compatible micrprocessor. It worked pretty well, though the biggest problem was that there was no indication at the phone that voicemail was waiting. You either had to check it, or go to the PC to see if there were messages.

DEC RA90/RA92 error codes

by cheri-post＠web.de

Hi everybody, does anybody have documentation for the RA9x drives, which goes beyond the user's guide ? A friend of mine has several drives which are faulty and display the type of error with an error code in the display. Unfortunately, the user's guide, which can be found online, doesn't reveal all these codes. Maybe there is a sort of maintenance guide somewhere ? I don't even know, if DEC ever published schematics of these drives, as they appeared on the market in the very early '90s... can anybody confirm that or do schematics exist somewhere? I'm personaly interested, too, as I'm running a SA800 and some additional stand-alone RA92 drives. So far, they have been fine, but this can change any time...

hp110+ info

by jwest＠classiccmp.org

Still can't find manuals. But here's what I know and maybe people can fill in the blanks. First info - Base model is 45711E, supposedly that designates 110+, 512k ram, & modem. The memory drawer has a model 82981A, which googling suggests is 128k ram addon. There's a metal shield over the chips and I don't have the right torq bit to remove. Upon boot all the ROM ID shows BBBBBB. First question - going into system config lets me set the memory split between main memory and edisk. All choices add up to 896k. How does that square with 128k + 512k? Second info - The PAM menu shows the following application choices - DOS CMDS, HP reflection, VT reflection, Memo Maker, Time Management, and BASIC. However, opening up the software drawer shows the following chips in the following locations 82863K-Reflection1 (0L), 45504K-MemoMaker/TimeMgt (1L), 82862K-BASIC (4L), 45555K-1/2-ExecutiveCardMgr (5H), 45555K-2/2-ExecutiveCardMgr (5L), 45548K-1/2-Lotus123 (6H), 45548K-2/2-Lotus123 (6L). Second question - I assume the PAM menu selections for HP reflection and VT reflection are handled by the single 82863K rom. I am curious why the Executive Card Manager and Lotus123 don't show up in the PAM menu? Misc. questions - The built in battery is obviously dead and won't hold a charge, as the unit won't run at all without the AC adapter. Every time I boot up though, it asks to reformat the A drive due to memory loss. More importantly, it has lost the date/time and system config settings (memory/edisk split for example). I'm curious if the date/time and config settings are kept by a different battery I may need to replace, or if all of the above is maintained by the single battery. I will have to hunt up a new battery. This 110+ is a really nice box! I'm quite fascinated by the built-into-rom HP terminal emulator (dumb terminal emulation won't do) as well as VT terminal emulator and serial port, all in a small package! Sweet! Thanks for any pointers! Jay West

Rich: I have a running 2000 here, that I can transfer files from. The 2000 does not have a BIOS like a PC. I believe the internal ROMs are just a POST and a boot strap, and the rest of the PC like BIOS is on the MS-DOS boot disk. I have been relayed this information by someone that used to develop and debug the 2000 for Tandy/Radio Shack. Do you know a way to dump them? I guess if I knew their starting address and length I could use debug. I also have Microsoft's Assembler for the 2000. Kelly PS I still owe you a phone call about the 2000s. I have one that I don't need, but it doesn't work. My suspicion is the power supply, but I've taken no time to verify this. This unit includes keyboard, HD controller, 10 meg drive and one or two 720k floppies, depending on the unit.

Tandy 2000 boot roms needed

by rcini＠optonline.net

All: I was able to get copies of the Tandy 2000 manuals for what is going to be a pretty challenging emulation project that I've undertaken. Since I don't have a 2000 system I was wondering if someone on the list who has one would be able to make copies of the BIOS ROMs from their machine. The BIOS/boot software is contained in two ROMs at locations U47 and U48. U47 is the "odd" rom and U48 is the "even" rom. Thanks again.

Transition panels and racking

by fireflyst＠earthlink.net

I'm trying to organize my PDP11 setup in a neat and tidy fashion, and I'm wondering, aside from the DEC transition panels which would be ideal, what sort of multi medium transition panels are there that I can attach things like multiple RS232 ports and SCSI connectors, etc to? The idea I'm after is something akin to the keystone patch panels, but with things like full RS232-DB25 that just attach with a plate or something, much like the DEC panels. Anyone seen anything like this?

vtserver, zrqch0

by drb＠msu.edu

I've assembled a basic PDP-11/53ish machine from parts. The CPU is >from a DECserver 550, converted back into an 11/53 by EPROM swaps. It has an RQDX3 and cable management board, and a Seagate ST-251 (40 MB MFM) drive. This is all installed in a BA213. So far, I haven't managed to get a load device working. I have an RX50, but it seems unwilling to work. I'm trying to format the disk. Jonathan Engdahl describes a trick to bootstrap XXDP utilities using vtserver: http://home.alltel.net/engdahl/xxdp.htm Vtserver does its magic, ODT-ing in the loader, and transferring the modified ZRQCH0 binary (from XXDP 2.5).

12/24-bit CPUs, was Re: Oregon Software Pascal/2

by rickb＠bensene.com

On Oct 13, 2006, at 2:32 PM, woodelf wrote: > So how many people have a working 24 bit computer on *this* list > at home or in storage? I may end up building a 24/12 bit design > ( the PCB layout and hardware design is my problem ) but designing > a schematic is not. I unfortunately don't have it (I had a chance, but didn't have a place to put it), but in high school, the school had a 24-bit computer. Quite an interesting machine. It used 8K-word magnetic drum memory. There were two complete redundant CPUs, each with their own 8K drum. There was a "shared register" between the two machines that could be used for inter-CPU communication. The machines also shared a very interesting I/O system that was housed in a large cabinet. The I/O system consisted of a Current Loop interface for an ASR-33 teletype (as well as paper tape reader control), an interface for a wide-carriage IBM output typewriter (individual typebars, not a Selectric-style device), and a large number of digital input and output ports, a number of programmable counters (to be used as interval timers), along with a bunch of A/D and D/A channels. There was also a BCD real-time clock which kept track of the time of day in hours/minutes/seconds, and also toggled a bank of flip flops at various rates which could be polled (no interrupts existed on the machine) to track time in various increments (1/2, 1/4, 1/8 and 1/16-th second intervals, if I remember correctly). There was also a set of thumbwheel numeric input switches which could be read, which, if I recall correctly, was 6 digits long, BCD encoded. The machine was all transistorized. No ICs anywhere. The machine was made by 3M Corp. (Minnesota Mining & Manufacturing). It was a process control machine. Its original use was as a natural gas pipeline pressure monitoring and control system by Northwest Natural Gas Co. in Portland, Oregon. After it was retired, it was donated to our high school. When I started at the high school, one of the drums had failed, so one CPU was inoperative. But, the other worked well. It was a two address machine, with operand address, and next instruction address. Addresses were of the form block/track/sector as the drum was organized. The instruction set was pretty simple, there were five bits in the opcode. There was an accumulator (24 bits), and a "B" register which could be used for temporary storage. The accumulator and B register were discrete registers, not located on the drum. Master timing for the machine was generated by a pre-written clock track on the drum, so all operations of the machine were synchronized with the drum rotation. Some kind of phase locked loop or the like was used to keep the drum rotating at a consistent speed (I think it was 3,600 RPM). The instruction set documentation had a "for optimum programming" section for each instruction, which provided formulas for the operand address and next instruction address to minimize the access time for the instruction. Typically, the operand address was the current address + 3, and the next instruction address was the current address + 6. Using these formulas would mean that the operand would be under the head after the instruction was fetched and decoded, and the next instruction would be under the head when the operation was completed. There were no index registers or base registers or anything like that. Addressing tables and such had to be performed by instruction modification, e.g., load an instruction into the accumulator, increment (or add 3 for optimum programming) to the operand address, store the accumulator back over the top of the instruction, then execute the modified instruction. Made list processing, stacks, and the like rather tedious. Each CPU was in a "drawer" about 8 to 10 rack units high. The drum was located in the center of the chassis, with circuit boards (which, IIRC, were about 7" long, and 5" wide) plugged into a backplane in the shape of a "U" around the drum. The two CPUs mounted in a small rack one atop the other. Controls for the CPU were simple. STOP, START, CLEAR, and LOAD. Clear cleared all of the working registers, and set the program counter to Block 0/Track 0/Sector 0, and halted the machine. Stop halted the computer after the execution of the current instruction was completed. START began program execution. LOAD put the machine into a hardwired loader that would allow address/data pairs to be loaded into the drum >from the paper tape reader on the ASR-33. The address and data were expected in octal, with a space separating the address and the data. These controls were momentary pushbuttons, with the START, STOP, and LOAD buttons lit to indicate when the machine was running, halted, or in LOAD mode. Five indicators would show the opcode of the current instruction. I seem to recall that it was possible to single-instruction step the machine by putting the machine into STOP mode, then holding the STOP button down when pressing the RUN button at the same time, but this memory could be incorrect. There was a two-pass assembler called SOAP that could be loaded from tape, then the source run through the paper tape reader twice, with the resulting object code stored on the drum. SOAP was pretty big, though, about 4K resident, which meant that you couldn't write anything much larger than about 4K in size with the assembler. I had spent time at the Oregon Museum of Science and Industry (OMSI) on their "Straight 8" PDP-8 System, and had learned FOCAL. I decided to try to write FOCAL on the 3M machine. I actually got to it to the point where small programs could be entered, edited, and executed. It did integer math only (24 bit), as floating point simply wouldn't have fit. When a line of code was entered, and the RETURN key hit, it would take about 1.5 seconds for the line to be parsed, error checked, and stored. This machine was not very fast. I wrote quite a few programs for this machine, including a blackjack game, tic tac toe, an alarm clock (you'd enter the time on the thumbwheel switches, and when the time came along, the teletype would ring the bell). Never got the IBM output typewriter working. It had mechanical problems (probably needed a thorough cleaning and lubrication). After I graduated from high school, the machine didn't get much attention. Someone tried powering it up at one point, and the drum in the still operating CPU failed..bearings went bad, and (fixed) heads crashed. The school eventually moved to a new building two years after I graduated, and that's when I had the opportunity to take the machine, but I had no place to put it, nor any way to move it. It was rather large (and heavy). The cabinetry was all painted a dark blue color. A white formica table top sat on top of the two CPUs in their small rack, and on top was a console with the real-time clock (using incandescent displays that had a GE-47-style lamp that shined through a piece of film that had the digit on it, which projected the digit on the a satin-finish plastic display screen). The clock was not made by 3M, but by someone else, was about 6 rack units high, and had pushbuttons to manually advance the hours, minutes, and seconds. It was implemented with transistor logic, connected as ring counters for each digit. Also on this panel was the six-digit thumbwheel numeric entry device. The IBM typewriter sat to the right of this panel. The controls for the CPUs were mounted on the front plate of each CPU drawer. To the left of the CPU drawers was the large cabinet that housed all of the I/O circuitry. It was crammed full of transistorized modules that plugged into a massive backplane. Each CPU had its own power supply, as well as the I/O cabinet, and the realtime clock. Each CPU needed a 20A 110V circuit. The I/O cabinet needed a 30A 110V circuit. The clock, IBM typewriter, and Teletype had their own 20A 110V circuit. I've been unable to remember the model number of this machine. I recall that it was 4 digits long. At one time, I had a big binder which contained a bunch of documentation for the machine, including the instruction set information, some information about the I/O subsystem programming, and also complete schematics for the CPU. I've searched and searched for it, and can't find it -- so I think that it must have been lost or accidentally tossed in one of many moves. I've searched high and low on the web looking for any references of any computers made by 3M, and have found nothing. My guess is that they didn't made computers for a very long period of time. My recollection is that the date on the documentation was 1965, but not sure of this. Anyway, probably a whole lot more here than anyone cares about, but it is my hope that perhaps someone out there may recall a machine like this made by 3M. Sure had a lot of fun playing with that machine. Learned a great deal >from it. The mainstay computing at our highschool was an HP timeshare system (initially, HP 2000C, advancing over the years to a 2000C', 2000F, then 2000/Access) which were accessed by dial-up ASR-33 teletypes. A "closed" BASIC environment, which was great, but no machine-level programming. I learned a great deal about "how computers work" from the old 3M machine. Thanks for letting me spew out all these memories. Rick Bensene The Old Calculator Web Museum http://oldcalculatormuseum.com

I'm not sure if it's a part of the system, or if I just stuck it there to save space. i'll pull it out tomorrow and take a look. Rack 3: Memory (possibly some other stuff mixed in there too, but the black units are primarily memory) Power Supply Fan Also included: Cabinet of RL02 cartridges. I recall at least one of the tapes was labeled "System" and something else. I can write down what they're all labeled, if it makesa difference to anybody.) Very large drawing tablet The fellow I bought this from told me it was used to do computer- generated graphics in the '70s and that it cost his company a quarter million dollars. I think it's depreciated since then. I bought it several years ago, but never did anything with it. It sat in his basement, then it sat in my garage. He told me it was working when decommissioned, but that was some time ago and it's utterly as-is. He also said it uses the same memory (behind the black panels) as in the Apple II. I bought a milling machine last week and need the room, so I'd like to see it go relatively soon. I'm in York, PA. I also picked up some HP-85B's at an auction last week. I only wanted two, so the rest are for sale. They came out of storage at a very nice lab and look like they're in great shape. Also available from the same auction is a system configured as follows: HP 9144 (tape drive) HP 7957B (hard drive) HP A-Series Controller 3065ST (board tester?) Make offer.

cctalk Digest, Vol 38, Issue 22

by alhartman＠yahoo.com

Sounds like you have the Floppy Cable backwards. Try plugging it in the other way around. You have Pin 1 and pin 40 flipped. A constant light and spinning motor is the usual symptom of that. Another way to get data off that machine is to use LapLink V and a Serial LapLink Cable. There were several work-alikes to LapLink like FastMove and others. You should be able to buy LapLink cables rather cheaply these days.

Tandy 2000 Floppy Drive Replacement

by marvin＠rain.org

I am playing around right now with a Tandy 2000, but it has no floppy drive. THE HD works fine, but I'd love to get the information off the HD, and that is difficult right now :). I tried a couple of standard 360K/1.2MB drives before Googling around. Does anyone have any information about what can be used as a replacement drive? Interestingly, the information I've seen indicates that the Tandy 2000 runs a modified version of MS-DOS 2.11 but the version on this machine is 2.0.

/34 & ba11-k regulator allocation?

by jwest＠classiccmp.org

I'm picking different pieces of various leftover /34 systems to make mine. I have a question about the regulators in the back of the /34's ba11k. Exactly what regulators are required as a minimum for a /34 that is just a dd11-pk with no expansion? Assume just a processor, one memory board, RL11 controller, one DL11W... nothing heavy. I have one ba11 with regulators in 4 positions and one with regulators in positions 1-3. However, one had a RK11D which I'm removing, one had a DD11-DK addition which I won't be using... and I would prefer to remove regulators that won't be used so they can sit on a shelf as spares and not be powered up all the time. I've looked in the 11/34 user manual as well as the ba11k technical manual and I can't seem to put together this info. Can someone point me in the right direction? Jay West

Unibus Termination KnowledgeQuest

by jwest＠classiccmp.org

Don wrote.... > The issue is there are two different aspects of the UNIBUS that are being > terminated: Aha. Now that makes sense! Thank you :) What that means to me then is that in the /34 the 9302 should only be plugged in to a the AB unibus out slot and NOT in a MUD slot, otherwise, you get a funny smell I bet :) So what about the 9312 in the /34 then. I assume it can only (no matter HOW it's jumpered) be put in a MUD (AB) slot, never in an AB unibus slot (Unibus in or Unibus Out). ?? Then, this of course brings me back to my dearly beloved (sarcasm) /45. In that machine, the cpu doesn't terminate anything from what I understand, hence the 930 at the front in slot 1AB. I assume in the /45 then, you CAN put the (appropriately jumpered) 9312 in the last slot (unibus out), and that you don't put another 930 in that slot and put the 9312 in a prior AB slot. Is that all correct? Thanks so much! Jay

Sun SCSI cables

by THX1138＠dakotacom.net

Hi, I posted this to the rescue list but have had no response :< So, I'll try again, here... ------ I've been trying to move my various peripherals into 611-type cases. Hopefully, get things a bit better organized. These stack nicely with ~12" (WIDE SCSI) cables to daisy chain from the OUT of one to the IN of the next. But, some *other* cases aren't quite as well-behaved. For example, stacking anything atop a 711 case requires a slightly longer cable to tether the 711 to the 611. Likewise, a 622 (?) needs a "cable stretcher" to span the gap to an adjacent 711/611/etc. Did Sun make *slightly* longer wide cables? Like 18"? Obviously, I want to use short cables to keep the chain as short as possible... And, can anyone suggest a good source for the ~12" and similar cables? Is there anything else I should be wary of? Thanks! --don

Unibus Termination KnowledgeQuest

by jwest＠classiccmp.org

TSIA :) I was skimming through the 11/34 manuals, and some confusion about the termination of that system made me re-read through the M9312 manual. Something doesn't seem right and points to me not understanding something. I seek enlightenment from the list. As I've understood things, you have to terminate both ends of the unibus. Let's say you're dealing with an 11/34 with no expansion backplanes (ie. just a DD11-PK). According to the 11/34 manual you put the M9302 terminator in slot 9AB. That makes sense, it's the unibus out. All the other AB slots are MUD (except slot 1AB, and we'll get to THAT in a moment). So about that other end of the bus now! The manual states you need a M9301 bootstrap/terminator just after the processor (typically, it may be further down if you have the FP and/or Cache options). That also makes sense to me, gotta terminate that "near" bus end. I had a M9302, but I didn't have a M9301. I wondered if I could use a M9312 in place of the M9301. So... I skimmed the M9312 bootstrap/terminator manual, and sure enough, it definitely talks about being able to use the M9312 instead of a M9301 in a processor that "has bus termination built into the cpu such as the 11/04 & 11/34". It even says that you must set the jumpers on the M9312 to remove it's termination capability, because in these specific processors the cpu provides bus termination. Ok, great. I can use my M9312 in place of the M9301 long as I jumper it as described. But... now wait a second! This gives rise to my first question. If the cpu is providing termination, and if you are going to use a M9312 on the near side you have to "jumper off" the M9312's termination ability... then WHY is a M9301 called a "bootstrap TERMINATOR". It must NOT be a terminator, just a bootstrap rom card. Right? It seems to me that if the cpu is providing the termination on the near end, that it is always doing so. Not JUST when you pull out the 9301 and put in the 9312. What gives there? That gives rise to my second question. IF the cpu is providing unibus termination on the one side... why can't you jumper the M9312 to provide bus termination and just put it in slot 9AB? You would get the other end (unibus out) terminated AND get your boot roms as well. This way the M9312 would replace both the 9301 AND the 9302. A few people I mentioned this to said you can't do that. But given the above... it seems logical. What's the scoop here? Clarification is much appreciated! Jay West

I did, in fact, use snipeswipe on that auction. But he had a higher bid in place than my snipe. Like I wrote, it wasn't losing the item, that didn't surprise me as my bid was low. It was being emailed by this guy who clearly didn't want the item, he was just outbidding others so he could turn around and charge them more money that it would have cost them if his sorry chemical composition was disassociated.

I bid on a Fujitsu magneto-optical drive. Ah, here's the URL still on my Snipeswipe page <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8786740987> . I was willing to go to about $16 (with shipping it would have been closer to $30). After the auction, the high bidder had the gall to email me to tell me that he sells items of the type I'm interested in and that I should visit his store. Of course, he sells MO drives for well over $100. So this creature outbids me and then tries to turn around and sell me the same item at a higher price. If I had been willing to pay more, I would have bid higher. I can't point out some way in which this behaviour is morally wrong, but it is certainly irritating. Jeff Walther

Timeline of Silent 700 models?

by sdc695＠yahoo.com

I don't know about the timeline of Silent 700s, but I seem to have a few of the bulkier ones in my garage (near San Jose, CA) complete with cassette tape drives if anyone wants to "take them off my hands". I even have a manual somewhere. I've also got some of the smaller ones (with built in acoustic coupler) but I'll probably keep that one (unless offered some $$$). If interested, contact me off list. They were introduced in the 70's (75/76?) as I remember. If you had your Bell 103 modem (I have one of those, another story), they were pretty neat things for "offline" editing of text files. Not exactly a vi editor, but better than paper tape (that's not saying much). Pretty reliable as a "hard copy" (thermal printing) terminal. Now days, you can use thermal FAX paper in them and it works OK. Great to hook up to your DP-8 or something of similar vintage.

OT: Soldering

by javickers＠solutionengineers.com

Is it just me, or is it now impossible to solder properly with "lead free" solder and "lead free" flux? Is there a decent make of flux available (like you used to get in those little round metal tins, and is nicotine brown in colour), rather than that utterly useless white water-based stuff? Also, while I'm ranting, the white rubbish flux I bought (to try to get a recalcitrant wire soldered up) has more warnings than I've ever seen on any product except peanuts before. Is it my imagination, or is it actually more dangerous than the stuff it's replaced? Grrr Adrian Vickers. (PS: This has nothing to do with terminals - I was fabricating a new battery pack for an Epson PX-8, due to the terminal expiration of the original) -- No virus found in this outgoing message.

Help with PDP11 modules, DEC and Plessey

by hachti＠hachti.de

Hi folks, today I digged out some PDP11 modules. I wonder what I can do with them. A Plessey-labeled Unibus Box with 11/34 front panel (the simple one) is still waiting to be picked up by me or put to scrap... Ok, what I found: * DEC M8265+M8266 (11/34A CPU), M9301 bootstrap/terminator Question: Is that enough to get the machine going? Do I need anything else (except memory and a kind of tty interface)? What about the "parity controller" which I don't have? * Plessey PM-DC/11 "status control", P/N 700485-100C Plessey PM-K11 "disc control", P/N 700490-101E Plessey PM-K11 "data control", P/N 700475-100B Plessey PMDC/11 "bus control", P/N 700470-100B These are four quad wide boards. I have no clue what they are/where good for. No connectors. Some DIP switches. If anyone could help me out with some information and/or docs - would be great. * Plessey PM-DC1100, P/N 703380-100H This hex wide board looks like an Unibus SMD disk controller. If it's that I am VERY VERY VERY interested in information about that. At the place I found the parts there is still an SMD drive.... It has three 26 pin ribbon connectors and one 60 pin connector. * Plessey memory board (?!), P/N 701830-100G Some information about that would be great. If anyone has something to share.... Ok, if anyone can help me..... All the stuff is available to anybody urgently needing it. Good night, Philipp :-)

Logos and websites

by cheri-post＠web.de

Hello guys, thanks alot for your answers. Unfortunately, I hadn't time yet to read the articles but I'll sure do that as soon as it's the case. To answer the question where I'm situated; I live in Germany. Lawers around here try to find possibilities to gain money by pointing out websites in wwhich law stuff my be broken in any way. It's absolutely rediculous and I don't want to have to pay a thousand euro jsut because a picture had been used without getting a permission for example. But from what you've been pointing out, it seems that it's not a problem to use some logos in the given context. And the context after all is purely educational / historical. So I guess that it shouldn't be a problem. I dont think that there will be issues the my ISP. Nethertheless, is it necessary to ad something like "Alll logos are trademarks of their owners bla bla..." ? Anyway, my site will be up soonish, I'll post a comment as soon as it's the case, as I'd like to get your opinions about it.

Timeline of Silent 700 models?

by Watzman＠neo.rr.com

Not exactly, but I can get close (I worked for TI ... in fact in the printer division). They were introduced in the early-1970's ... I was using second generation models in 1977. By 1989 (when I joined TI), I'm pretty sure that they had been discontinued, but they were still in widespread use, and were still being supported.

Still Looking for Help

by jrkeys＠concentric.net

Hello All I'm still looking for help with the second rescue attempt in Georgia and need either 182 donors of $10 each or 1820 at $1 each. I would like to get to these items before winter really gets here, so please if you can spare a $1 (one buck) send it to the Houston Computer Museum, 15827 Thistledew Drive, Houston, TX 77082-1432. Cash or a check will do. Again the first trip was a great success and many thanks to all donors for that rescue. www.housoncomputermuseum.org Thanks in advance to all, John Keys

Logos and websites

by cheri-post＠web.de

Hey all, just a question: I'm working on a website which presents my collection of classic computers. On the left side, there will be a navigatio bar with the company names and the respective modes. I'd like to directly use the logos (images) of the brands in order to represent their names. Could I run into to difficulties doing that? E.g. a company asking me to remove it or otherwise being confrontated with law issues ? For those who run a website? What are your experiences? Thanks for any hints.

Need 3 dectapes read

by staylor＠mrynet.com

I've tried manually searching the archives, but I can't find any references... Was there someone who would be able to read 3 DECtapes for me? Two of them are >from PDP-11 RSTS systems. The third has sources from ancient UNIX (circa 1974) possibly 4th or 5th edition. Thanks in advance! -scott staylor at smedley dot mrynet dot com
