Just to add a little more info, When I returned to work today I got the exact model of my printer, its a 5218 A02. And it does not have any connection on the back for the feeder or tractor unit as described in the service manuals. It would appear that you would have to add some sort of wire harness assm.??? Any help is appreciated. I am having no luck tracking down a cut sheet feeder. Thanks! Blu

Decserver 200/MC as console switch?

by bdwheele＠indiana.edu

I've got a decserver 200/mc and I've managed to get the terminal server software to load. What I'd like to do is set it up so I can hang my various unix boxes off of it and use the console port on the terminal server to switch between them. [think: serial kvm] I know I'm going to need a pile of null-modems, but I have no idea how to configure the server to do what I want. The documentation I've come across seems to indicate that this is possible. Anyone have any documentation on how I'd set this up? I don't need LAT, so that's not really an issue. [of course, if anyone has a newer terminal server that'll do this that they're willing to part with for postage, I'd not turn it down :) ] Brian Wheeler bdwheele(a)indiana.edu

finds from TRW Swapmeet (AKA Northrup Grumman swap meet) today

by jwstephens＠msm.umr.edu

I found a device called a Micro Lab I. It camed with a TI 9900 card and a 6802 card. It is dated 1979 from looking at the date codes on the parts. It fired up and ran perfectly. Anyone have any experience on this unit? I found a 2 high VME board with a TRW RH32 processor on it. A quick search ofGoogle showed that this has a redhat port and is a Raiation hardened 32 bit RISC processor made by TRW and Honeywell. The chipset has a CPU-1 CPU-2 MPU-1 MPU-2 and SCU-2 plus two ORCA asics. I don't know if it is dual cpu, fault tolarant (dual cpus for redundant function), or a single cpu set with two large cpu LSI chips making up a single processor. Jim

Why one should never give an interview

by vcf＠siconic.com

Ok, more fuel to add to the discussion about reporters being complete idiots. I did an interview recently for a local paper. The writer seemed very bright and asked good questions. The article came out today. I was impressed with the technical accuracy. However, there was one MAJOR problem: the article said that I sold recycled computers to the Alameda County Computer Resource Center. Now, this may at first seem like a minor error, but it's huge. First of all, under agreement with the ACCRC, I act as a drop-off center for computer and electronic recycling. All items dropped off at my facility are in fact donations to the ACCRC, and donation receipts are given for income tax deductions. Second, the computers and electronics collected are then delivered to the ACCRC where they then refurbish and distribute the computers they receive as an officially registered 501(c)(3) non-profit organization. To say that I sell computers to the ACCRC makes it seem like I am engaged in fraud. So now people who read this article and have or were considering donating items through my service to the ACCRC will think I am in fact fraudulently collecting computers to resell to a non-profit. Nice. In short, I have been libeled is a seriously egregious fashion. So much for the free publicity I was hoping for. I'll have to wait until tomorrow (Monday) to see what the paper intends to do to rectify the situation. If they don't play by my rules then I'm getting an attorney. This incident may well be the final straw. From now on I'm now considering telling any reporter that comes within 10 feet of me to fuck off. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

One That Got Away (was: Woohoo! Another DEC score!)

by mross666＠hotmail.com

Date: Wed, 26 Nov 2003 18:28:30 -0500 Subject: Re: One That Got Away (was: Woohoo! Another DEC score!) >>...There. That's my True Confession(tm). I've got a couple of those... a Connection Machine CM-200, and a pdp-12 :-( The CM-200: In the early 1990s, I was in Edinburgh, trying to track down some pdps. I ended up at the Edinburgh Parallel Computing Centre (EPCC), where I found a pdp-11/45, just decommisioned, which had been running as a communications front end. I also found the most impressive computer I had (and have) ever seen: a Connection Machine CM-200, flashing all its lights at me in a very beguiling fashion! I determined there and then that I would try, in a few years when such machines were being retired, to secure one for the Corestore. I let around five years go by, not realising just how long a period that is in high-performance computing, before I spoke to the people in Edinburgh again: 'oh I'm sorry, we finished with that machine six months ago - it was carted off for scrap. We kept a few of the boards as souvenirs...'!!! The pdp-12: In 1993 I collected a pdp-12 from a medical research place. At the time I removed it, there were still two other pdp-12s on site there, one complete and in use, the other dismantled for spares. One machine remained in intermittant use until at least 2001! I had been promised the remaining equipment when it was finally surplus to requirements, and telephoned the place every few months, always getting the reply ' it will be a few more months at least'... then came the fatefull day in early 2002 when I called and heard 'oh sorry we forgot about you - we got rid of it all a couple of months ago, it all went to an old computer enthusiast who asked us for it!' Grrrrrrrrrrrrrr. At least the -12 *did* get saved... Mike http://www.corestore.org _________________________________________________________________ Share holiday photos without swamping your Inbox.

Documentation for AppleSoft & command hook?

by vcf＠siconic.com

I'm looking for documentation that explains how to actually use the & (ampersand) command hook in AppleSoft BASIC.

Interesting Find

by marvin＠rain.org

Today at TRW turned out to be rather interesting. A friend of mine was selling some stuff that included a funny module that didn't sell and I ended up with it. Turns out that it is an Amplifier Module (red/green front) for the Electronic Associates TR-10 Desktop Analog computer. Doug Coward has a picture of the computer on his site at http://dcoward.best.vwh.net/analog/eai.htm.

On Topic? Looking for opinions...

by john＠boff-net.dhs.org

Let's see if this goes through, last two didn't... Now I know this falls under the 10 year category except for the video card and SCSI card: I'm slapping together (finally) a P200 (not even MMX) Linux box with a classic AMD 10Mbit PCI NIC (Sridhar got me hooked on 'em and they certainly are tanks), an old AT motherboard with most likely a serial mouse to keep it as classic as possible and a 250 watt p/s. Running the beast will be an old 2GB IDE Maxtor I dug up, an old 4x IDE CD-ROM (Toshiba?) and then 2 Seagate 4/4.5GB half-height drives I have laying around, attached to a Diamond Fireport 20/40 (non-ultra). For video, it'll have a PCI Jaton TNT2m64 32MB so I can at least get decent color when I'm messing with some of the graphical stuff. I'll be using a 14 year old (still works fine) clickity Ultra 2000 AT keyboard with the beast. Oh, sound will be one of the original full length Creative Sound Blaster 16's with Daughter Card (dated 1990?). The big question is: should I go with Slackware or GenToo Linux as my OS? This unit will be doing a little web serving and will become my email server since friend's server is unreliable lately (Win2k on a college dorm network - obviously off when it goes home with the guy at breaks). I know some are suggesting NetBSD, but I'm looking to make this thing easy enough so my gf can tinker with it and get converted from her eeewh, XP OS, while making it not so much of a chore to do a basic config and get serving up and running. Any thoughts would be appreciated. Oh, also, I may be tossing in dual PCI 16/4 Madge/IBM Token Ring NICs to a Bay Networks 504 unit with Fiber ports and NMM just for ha-ha's and something to hobby with in the future. I also have a 3COM 12 port RJ45 Token unit, a DCA Microchannel/ISA Token card? (unable to find details on) and the old IBM 8228 MAU with a lot of 6ft Vampire to DB9's if anyone's looking for one, shipping and it's yours (I remember someone on the list was looking a few months back, but I forget who) -John Boffemmyer IV PS: "A Linux box isn't a Linux box until you get it serving to the Internet >from something that is barely big enough to have the Ethernet line plugged into it." - I rather like that quote, you'll never see Windoze doing that.

Formatting and verifying MFM hard disks

by ian_primus＠yahoo.com

As I have been sorting and cleaning over Thanksgiving, I decided that I would build up an extra PC clone for the sole purpose of formatting and verifying various types of media, such as SCSI, IDE, and MFM hard drives and 3 1/2 and 5 1/4 floppies. I originally planned on just tossing an MFM card and SCSI card into an older AMD K6-2 233, and installing two floppy drives. But, as I got started, I remembered how the old MFM drive controllers worked, and how they kinda take over the boot process. Also, since MFM drives need to be low level formatted for a specific controller before they can be high level formatted, I can't really just format them from Linux. I found a Seagate card that has a nice boot screen with a drive formatting utility, but it only handles eight different Seagate drives. I've got a couple of other old controllers, none of which have such a nice utility, and all of which prevent me from booting from CDROM (they intervene before the BIOS boots from a disk, and when the MFM card can't boot a hard drive, it tries floppy drives, but it doesn't see the CDROM, and won't return control of the boot process back to the PC's built in controllers) Also, in this process, I realized that I can't find my DOS disks! It's been a long time since I booted DOS, and an even longer time since I've messed with DOS on XT's, so I don't know where the disks are. What I think I need is a disk with DOS 3.x and debug. I remember having to use debug to invoke the built in formatting program on most hard drive controllers. Anyway, what I really want to do, is have a computer that would have an MFM card in it, and be able to work with any MFM drive. I'd also like to still be able to boot off an IDE hard drive or a CDROM, since I want to install Linux on an IDE drive on the motherboard's controller, and use that for high level formatting. I can probably work around that by having a Lilo bootdisk, and booting that first, then the system could continue booting from an IDE drive. But, if I did this, what is the best way to do low level formatting on MFM drives? Is there a way to invoke the card's internal formatter from Linux? It's been a while since I worked with this stuff, can anyone refresh my memory? Thanks! Ian Primus ian_primus(a)yahoo.com

VMS .iso image for SimH?

by gtoal＠gtoal.com

After a long wait I have finally got membership of Encompass and have requested and received an OpenVMS licence for SimH (I entered serial no #1, hope that'll work! - leaving the field blank was rejected) I thought that once I had the licence, and simh built and installed on a dedicated machine, that it would be easy to download a .iso image and get started. No such luck! From what I can tell the only way to get the VMS code is to buy the $30 CD? Is it permissible to get a copy of the .iso from someone who has it, since I'm now licensed, or is an original CD a requirement (legally I mean, not technically). If it's OK to download a .iso from someone, could anyone here who has one online and a suitably high bandwidth connection please point me at a copy? I'm desperate to get started! :-) By the way, to the person who asked about where to get online to a real VMS - the Deathrow Cluster has both an Alpha and a Vax and they're real nice & helpful guys: http://deathrow.vistech.net/ About a month ago I installed Edinburgh's Imp77 compiler on their Vax, which is the first time that compiler has been run in many years! - it wasn't possible to 'vest' the binary on the University's Alpha which was the only VMS I had access to initially...

Woohoo! Another DEC score!

by jwest＠classiccmp.org

I'm the proud new owner of a PDP-11/45! Woohoo! It's even purported to be working. Comes in a DEC rack with power supplies, and a whole bunch of what looks to be DEC A/D stuff (which I have no interest in and is already spoken for by another listmember). God I love the look of those triangular front panel switches! Just have to arrange going and picking the thing up. It is in central eastern TN. In the event I can't make it down there before the pickup deadline (roughly 30 days), is there a listmember in that area that might pick it up for me and hold it a bit longer if that becomes necessary? There's no drives, the rack is mostly empty cept for the cpu. The A/D stuff is very light, mostly just a couple panels and wires. I really never thought I'd find one of these "in the wild" these days :) Jay West --- [This E-mail scanned for viruses by Declude Virus]

And the whole time I've been mostly surrounded by old farts. Rather depressing sometimes. There's a big problem getting younger people into ham radio, too... Hell, getting ANYONE.

My Displaywriter

by Sharp51482＠aol.com

Hi, First off, I'd like to say that I am very happy to have found this group. It has been interesting to ready past posts on topics that I enjoy. I am most interested with IBM System/3x's and the Displaywriter System. I direct the Audio / Visual Department of a High School, and the first thing I did when I got there 3 years ago was to put my old IBM Displaywriter back to work. It is used daily, and some people think I am nuts for using it to deal with crucial data; However I sit back and laugh when there PCs are crashing, hanging, and causing them all kinds of problems! Anyway I am in desperate need of 2 things for my Displaywriter. First I really need ReportPack software. If anyone knows where I could get a copy that would be great. Secondly, I need the groups advice on my printer. I currently have the daisywheel printer with no sheet feeders or tractor feed. I use standard greenbar paper for most things, and it is a real pain to have to keep hitting the start button after each sheet is done printing, plus I have to realign the paper correctly. This will especially be a problem if I even find the ReportPack software. I would like to find the cut-sheet feeder or the tractor feed attachment. According to the books I have it seems that these connect to a small connector on the back of the printer. My printer has a blank plug in that space, yet the books reference the same printer I have. Was there some kit of parts that one would install in the printer?? Thanks so much for taking the time to read this, any assistance would be great! Blu

Source for disk & head cleaning?

It is important to keep the heads clean. It doesn't take long to damage a disk with a little something stuck to the heads. Later Dwight

Is MECC still around?

by Sharp51482＠aol.com

I don't believe so but could be wrong, we used to have 1000s of MECC programs at the school where I work, all for the Apple II series. At one time we even had them all on a DigiCard server. The system would track student progress and run the various programs automatically based on a students progress. Our last DigiCard controller dies about 3 years ago. We still have some of the 5.25" disks but 1000s of the software binders went into the dumpster about 2 years ago. I would have given them a good home but I didn't have the space, and sometimes I just have to say "NO".

I've been putting together a web page about BASIC games I've found interesting -- I ran out of time so there's not much there yet, but I extracted TRADER and TRADES (thanks to Eric Smith, whose tsbextract and tsbdecode programs I adapted). If anyone else is looking for something particular, I could easily be persuaded to add it when I have time, assuming it's something I can find. I've got images of David Ahl's DECtapes, as well as the HP tape, and a few other sources. http://www.dunnington.u-net.com/public/basicgames/index.html -- Pete Peter Turnbull Network Manager University of York

Server question

by jpl15＠panix.com

This is more-or-less on-topic, I theenk... I wanna set up a small, dedicated server at home... to do several things, not the least of which is allow a private gateway so L33T folks can play with my 11/44 on-line. I also have a weather station whose data I wish to collect and make available (for the Ham radio SkyWarn group here in NV). As well.. there are some files to make available for FTP.... I'm thinking of a Webcam on top of my antenna tower... etc etc. I intend to buy older computers to do the WX stuff, another for a dedicated Webcam, and maybe a radio VHF packet and RTTY gateway. All this would be stitched together via ethernet / cat 5 / etc. I have pretty decent cable-modem service right now - if they ever get around to pulling DSL in I'll switch to that... so that would be the 'outside world' connection. So the question is: cheap used PC with X-GB drives for the server - what software would be also simple to get up and running w/out needing to go to a year's worth of school... preferrably something in the Linux world... what is the minimum platform specs that would run this server software: proc speed, RAM size - HD space?

for trade: PDP-8 Programming Handbooks

by jack.rubin＠ameritech.net

These are left over from my grad school days (doing image analysis on an 11/45)- a two volume set of paperbacks printed in 1972. Partial contents: Volume 1: Computer Programming Fundamentals - computer, programming, techniques Online Operations - system description and ops (pdp8e), loading, editing, debugging Advanced Programming Techniques - i/o, DECtape, FPP Programming Systems - OS/8, educational systems Volume 2: Interactive Languages - FOCAL-8, 8K BASIC Compiler Language - FORTRAN Machine Language - 4K and 8K assemblers Covers are scuffed and creased but bindings are tight and contents are clean and intact. Pages are yellowing - DEC did not spend a lot of money printing these - but not (yet) brittle. These things should be really be .pdf'd but it would require destroying the bindings and I'm not ready to do that with this set. Will trade for original Compupro/Godbout CPU-Z, Disk1A, Disk3, or Morrow or ? docs. Jack Rubin

On Topic? Looking for opinions...

by john_boffemmyer_iv＠boff-net.dhs.org

Now I know this falls under the 10 year category except for the video card and SCSI card: I'm slapping together (finally) a P200 (not even MMX) Linux box with a classic AMD 10Mbit PCI NIC (Sridhar got me hooked on 'em and they certainly are tanks), an old AT motherboard with most likely a serial mouse to keep it as classic as possible and a 250 watt p/s. Running the beast will be an old 2GB IDE Maxtor I dug up, an old 4x IDE CD-ROM (Toshiba?) and then 2 Seagate 4/4.5GB half-height drives I have laying around, attached to a Diamond Fireport 20/40 (non-ultra). For video, it'll have a PCI Jaton TNT2m64 32MB so I can at least get decent color when I'm messing with some of the graphical stuff. I'll be using a 14 year old (still works fine) clickity Ultra 2000 AT keyboard with the beast. Oh, sound will be one of the original full length Creative Sound Blaster 16's with Daughter Card (dated 1990?). The big question is: should I go with Slackware or GenToo Linux as my OS? This unit will be doing a little web serving and will become my email server since friend's server is unreliable lately (Win2k on a college dorm network - obviously off when it goes home with the guy at breaks). I know some are suggesting NetBSD, but I'm looking to make this thing easy enough so my gf can tinker with it and get converted from her eeewh, XP OS, while making it not so much of a chore to do a basic config and get serving up and running. Any thoughts would be appreciated. Oh, also, I may be tossing in dual PCI 16/4 Madge/IBM Token Ring NICs to a Bay Networks 504 unit with Fiber ports and NMM just for ha-ha's and something to hobby with in the future. I also have a 3COM 12 port RJ45 Token unit, a DCA Microchannel/ISA Token card? (unable to find details on) and the old IBM 8228 MAU with a lot of 6ft Vampire to DB9's if anyone's looking for one, shipping and it's yours (I remember someone on the list was looking a few months back, but I forget who) -John Boffemmyer IV PS: "A Linux box isn't a Linux box until you get it serving to the Internet >from something that is barely big enough to have the Ethernet line plugged into it." - I rather like that quote, you'll never see Windoze doing that.

This died out, Do we want to do our own Wiki? The last suggestion was that we make entries at WikiPedia [ http://en.wikipedia.org/ ] I think we would be better served with our own Wiki, we would be able to arrange the data in a way that would mean something to us. Otherwise would have to have our machines peppered about in between other subjects. I suggest this arrangement: Introduction Year : Manufacturer : Model : User : Individual machine Some Wiki's also allow for a user's home page. There I sugest each user tell us about their collection / machine (with a link to the machine page)

PDP-11/73 boots!

by ian_primus＠yahoo.com

A few minutes ago, I got my PDP-11/73 to boot. I installed the disk controller and connected the hard drive. I typed in the boot program, and booted from the BRU standalone tape. It worked! This time it didn't crash, since it could find the drive controller. It booted up and displayed this: http://24.194.65.231/images/screen1.jpg I haven't figured out how to get past this though. Typing /dev gives me this : http://24.194.65.231/images/screen2.jpg I tried typing in a device name, but it just gives me a syntax error. Hardware wise, I think that everything is working together properly. I don't know how to use the software though... To start off with, I'd like to run a flavor of UNIX on this, since I know UNIX very well. Any reccomendations as to what I should use? BSD 2.11 should work on this, but I don't know how well. In the future though, I'll probably install a PDP specific operating system, like RSX or RT11, and learn that, but at least as I get things going with the hardware, I think I should at least stick to software I know :). Also, once I do get something installed on the hard drive, how do I boot it? Currently, toggling the boot switch doesn't boot the machine. Should it? Will I have to type in a bootstrap code every time, or can I make a ROM do it for me? Here are some more pictures I took of my current setup. This is what the computer looks like at the moment. The side panels are off the rack, and the cables are just hanging around the front for the time being as I am just testing at this point. I'll neatly route them out the back later. I'm currently using a Lear Siegler ADM3A, since it was convenient when I was first hooking it up. Not only that, but I really like the ADM3. Mine's missing two keys, but it works. http://24.194.65.231/images/pdpworking.jpg This is one of the brackets I had to make to mount the Fujitsu Eagle into the rack. It's made out of a Home Depot bracket that originally was wider, and had two little wings coming off the top of it. I think it was intended to join two 2x4's together somehow. I cut it down with a Dremel tool, and drilled new holes in it. It worked out very well. http://24.194.65.231/images/homemadebracket.jpg Ian Primus ian_primus(a)yahoo.com

Free IBM System/36 (5362) and Kienzle 2000 in England

Here's another one. Why does this seem familiar? Didn't I already post this to the list? Or did someone else? At any rate, it just plunked into the hopper so I'm passing it along. An IBM 5362 in England. The address makes no sense to me: I think this is an estate sale company in four locations(?) North Leaze Farm, North Cadbury, Yeovil, Somerset. Take your pick. Sorry, my geography of the UK does not enable me to figure out where this is exactly. Or maybe it IS the address (quite odd by US standards at least). Or maybe it doesn't make sense anyway. Whatever.

Flat Earth?!

by tothwolf＠concentric.net

For those of you who may have wondered where I'd gone, I really didn't fall off the face of the Earth (and contrary to what some folks might believe, the Earth still isn't flat). I'm currently recovering from a multi-drive failure in my RAID-5 array. I was very, very lucky in that only one of the drives died a horrible death, with the 2nd having a semi-recoverable error. The second drive failed before the array could reconstruct itself, and my spare drive was already in use. Had I been running an OS where I didn't have the source, I probably would have lost all of my data (roughly 25-30GB currently), but since I had the source to the RAID software, I think I've managed to recover most everything. Let this be a warning to anyone else with a nice RAID setup who also doesn't keep current backups... My DAT drive died about 6 months ago, and Sony can't seem to cough up a service manual. [If anyone has any surplus DLTtape IIIXT tapes sitting around collecting dust, feel free to contact me off-list. I managed to collect a DLT2000 drive right before my DAT drive died that still hasn't attracted the proper tapes. I'd also like to find an inexpensive source for new or low mileage 4/9/18GB UW SCSI drives, as I think it may be best for me to replace the entire lot of old 9GB drives that made up my RAID-5 array.] I also have a number of things that still need to get sent out to folks. If anyone is expecting anything from me and doesn't hear from me soon, contact me off-list and remind me. -Toth

OK, mine concerns a PDP-11/40. When I got it, it wasn't in a rack, just lying on the floor, minus the power supply, a few wires cut, a bit of rust here and there, and no docs. At the time I didn't have a Unibus machine with a full lights-and-switches front panel, so I took it anyway. After 2 or 3 years of lying on *my* floor, I gave up trying to get a power supply sorted out, and gave it away to someone whom I suspect broke it up. The sad thing is that it had a full complement of boards in the CPU (my present 11/40 has no FPU, no MMU, etc) and a few extra goodies. Moreover, it turns out to have been been one used for the developmenmt of MUMPS, so it was actually a more historic machine than many. -- Pete Peter Turnbull Network Manager University of York

Source for disk & head cleaning?

by jwest＠classiccmp.org

I think I posted a query about this before, but don't recall any answers.... HP recommends cleaning the heads on the 14" drives with a flat wand, and a cleaning sleeve that fits over it. They also recommend the same device for cleaning the fixed platter, through an access port next to the heads. I seem to recall that old Microdata Reflex drives I used to work on wanted the same thing. You put the sleeve on the flat wand (the wand is much like a tongue depressor in shape, but a bit longer, and plastic), dampen with ISO 91, rest it on the platter through the access port, and slowly turn the hub by hand. I have searched the net, and can't seem to find a source for these wands and cleaning sleeves anywhere. I would have thought they'd still be around. Does anyone have a source for these? Thanks!

Mounted on the top cover is a Motorola RTL-5820A PROM socket and there is a spare one store in the cover RTL-5821, There are also several cables in this storage area. I got no manuals with it and would like more information if someone has worked with one of these before?

Computer terminology and political correctness

by rdd＠rddavis.org

Did anyone hear that some bureaucrat, in charge of purchasing for the city of Los Angles, has sent a letter to all of the city's suppliers of equipment, asking them not to use the "insenstive" words "master" and "slave" in relation to equipment sold to the city? Maybe this means that there will be a glut of politically incorrect surplus computer equipment and documentation available there. Of course, they'd probably recycle it into scrap so as to not risk offending purchasers... too bad they don't just recycle the political correctness into something else. -- Copyright (C) 2003 R. D.

by TRASH3＠splab.cas.neu.edu

Pat, I had sales brochures from MDB systems that I sent along to Al to scan in and place on the website. From there they were going to another person on this list that requested them. Check Al's website to see if he got a chance to post the MDB stuff, and if that fails, we can see if the stuff is still with Al, or got forwarded to the next person (whom we can then ask about) Joe Heck

MDB MLSI-DB11 (DB11-H?)

by pat＠computer-refuge.org

I've just acquired a MLSI-DB11 (produced by MDB), which is a QBUS adaptor that sort-of looks like an SMD disk controller. I'm not quite sure if it's that, or something else. The closest thing I've found to what it is the DEC DB11-H adaptor, which I can't find any description of anywhere. The MDB card is a dual-height QBUS card with a 60-ish pin connector, 20 pin connector, and 2 smaller 10 pin headers on it (might be off by a couple pins on those counts). Does anyone know 1) what this is and 2) anything about it? Thanks, Pat -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/

DC 30 tapes?

by rigdonj＠cfl.rr.com

I went scrounging a couple of days ago and found a big box of DC 30 tapes. Is anyone familar with these? Or know of any systems that use them? I THINK these came from a computerized component tester made by Seimens. They look like audio cassette tapes but are slightly larger. These tapes are made entirely of plastic and don't have the metal plate on one side like the DC 300 tapes, HP-85 tapes or DEC Compactapes. I think the Seimens component tester may be a rebadged tester make by Analog Devices. At the same place I found a big pile of Analog Devices plug-ins to mount and connect various types of ICs and other solid state devices but I didn't take the time to see if they fit the Siemens marked testers.

Paper tape is still available from several suppliers, though only a few companies still actually make it. However, not all modern "oiled" tape uses resin -- some manufacturers do still use oil, according to the company in the UK who are getting me some (from Germany). Resin is an effective barrier, but worse than useless as a lubricant. -- Pete Peter Turnbull Network Manager University of York

Sadly, Frank da Cruz no longer keeps older versions of Kermit online (something I regret, as periodically I need to find yet another version for some newly-acquired machine, and also because I dislike the bloat that happened between C-Kermit 5 and 6). Luckily there are other places to find it. Thanks to Tim Shoppa, several DECUS tapes are available which have versions of Kermit-11. It's usually in account (directory) [356,040] on the tapes which included it. Look for the file k11ins.rno (or k11ins.doc, which is a flat ASCII file but most servers wrongly assign a MIME type of application/msword to it, just because of the suffix) for release notes. .rno is a RUNOFF file, the source for a document processing system akin to (but much older than) troff. 3.51 (Spring 1986) runs under 7.2 but doesn't handle binary files properly, and only builds under 8.0 or later. It's at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx /decus/rsx86a/356040/ 2.30 (June 1985) says: "This is release 2.30 of Kermit-11. It requires RSTS version 7.2 or later, RSX11M v4.0 or later, or RSX11M Plus version 2.0 or later, or RT11 version 4.0 or later, or P/OS version 2.0 or PRO/RT11 version 5.1 Minimum system requirements to run Kermit: RSTS v7.2 or later, with multiple private delimiters" It's at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx /decus/rsx85a/356040/ 2.17 (August 1984) says "This is release 2.17 of Kermit-11 for RSTS and RSX11M/M+. It requires RSTS version 7.2 or later, RSX11M v4.0 or later, or RSX11M Plus version 2.0 or later, or RT11 version 4.0 or later. Minimum system requirements to assemble and link Kermit RSTS v8.0 or later, with multiple private delimiters and RMS V2 Kermit-11 will run on RSX11M version 4.0 and RSTS/E version 7.2 as long as the task was built without using RMSRES. To be able to build KERMIT on RSTS version 7.2 or RSX version 4.0 you will have to get RMSLIB.OLB and MAC.TSK from RSX v4.1 or RSTS v8.0." It's at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx /decus/rsx84a/356040/ Most of these have pre-built binaries in the form of .hex files; these are flat-ASCII hex representations of the binary, intended to be stuffed over a serial line by a simple terminal emulator or whatever, in case you don't already have Kermit or something similar to transfer a binary. There are also de-hexifier programs in various forms (BASIC, FORTRAN, C, etc). Most of those directories also include other verisons of Kermit (ie, not for DEC OSs). I discovered that last URL I gave has C-Kermit 4C :-) -- Pete Peter Turnbull Network Manager University of York

Want to borrow TTY for a few minutes...

by v.slyngstad＠verizon.net

I mentioned this before, but the subject line may not have caught the right people's attention. I need access to an ASR TTY with the reader-run mod to do some final testing on some cards I am developing for myself and the group. If you have a pdp-8i or pdp-8L that's great, otherwise I can bring my 8L. I am in the Portland (PDX) metro area (Beaverton, actually). The cards have already been tested with a TTY which does not have the reader-run feature, so it is that specific feature I still need to test. Anyone out there who can help? Thanks! Vince

Paper tape

by davidmercier＠newengleng.com

Newer paper tape is not oil impregated at all but has a barrier / lubricant made from resins. Tape is still available from The Trybus Company in Pittsburgh. (412 367-1880) They also carry Mylar tape which I prefer. Quite often a customer will come to me with an old worn out executive tape and ask me to "do Something". I will generally read in the tape using a DSI reader that I have slowed down to 30 CPS and have narrowed the strobe width to 1/6 the charactor width. I will then use a FACIT 4070 to generate a new tape onto Green/Gold mylar. On executive tape using all 8 bits and no parity I use norton disk edit to make any manual repairs. This eliminates the need to splice fragile originals. David A. Mercier New England Engineering Services 25 West Street Stafford Springs, Ct. 06076 (860) 684-5980 Fax: 684-5982

PDP 11/73 is ALIVE!

by ian_primus＠yahoo.com

Last week I got the system unit and the tape drive mounted in the rack, and yesterday, I managed to mount the Fujitsu Eagle. Now I'm trying to figure out how to hook it all up... I have been tinkering with it this morning, and finally, about a half hour ago, I was able to see some activity. I found the information on the serial board in a handbook, set the terminal for the proper baud rate, etc, and connected it to channel 3 of the card. Powering it up gives me the @ prompt. So far, the only things in the machine are the CPU, the serial card, a 1mb memory board, and an Emulex tape controller. Now that I have gotten it to do something, I'm totally lost. I've never worked on a machine like this before. I don't even know how to type in the boot program. I have a tape boot program here, on a piece of paper, but I don't know how to type in the values. I've tried all sorts of commands, all of which yield a ?. Typing P seems to step the processor through something, as it prints 000002, and then typing P again increments that value. G prints 177777, and the LED on the tape controller lights briefly. Same thing if I toggle the boot switch. I tried loading a tape into the drive and putting it online, but I get no drive activity when I toggle the boot switch. So, can anyone offer hints or suggestions as to what I should do next? I'm lost... Thanks! Ian Primus ian_primus(a)yahoo.com

PAIA PVI-1, VT-103

by swtpc6800＠comcast.net

Here is a page scan and the text from a 1978 PAiA catalog. The PVI appears to be Don Lancaster's TVT-6. http://www.swtpc.com/mholley/PAiA/TVT6_640.jpg Michael Holley www.swtpc.com/mholley Don Lancaster's ingenious design provides software controllable options including: Scrolling Over 2K on-screen characters with only 3MHz bandwidth Full performance cursor Variety of line/character formats including 16/32, 16/64 even 32/64 User selectable line lengths You'll want to see the operational details on this first. The PVI-1K is not the universal answer to every video display requirement. In applications where its minor limitations present in?surmountable obstacles to a design, more expensive techniques should be used. If you are in doubt, the PVI is completely described in the July and August, 1977 issues of Popular Electronics. Reprints of these articles are the instruction set for this kit and are available separately for $2.00 postpaid refundable upon purchase of the PVI kit. Complete kit includes circuit board, all parts and instructions and is available in either of two forms. PVI-KM Ready to go with KIM's $34.95 wt. 1 lb.

Grandfather system RTE6/VM?

by aek＠spies.com

Thanks, Al, for the microcode rom dumps (however the 12823-80020.bin, F-SIS is missing - lost somehow during copying?). -- It should be there now I've seen that the base ROMs slightly differ from the microcode listing in the 2109-90004_1000EF_uPrgRef_Apr80.pdf from your site. What is the relation between both sets? -- The set that is up there was the last released set, and uses x8 proms instead of x4. Release histories of the firmware can be found starting on page 33-1 of the CE manual. I've hacked together a simple microcode disassembler for these ROMs, with the exception of the 1816-* ROMs that I do not know how to handle (any further info?). -- That is the MX IOP firmware. They are x4 parts (256x4, 82S129's to be exact) I suspect Bob Supnik or Mike Gemeny may already have disassemblies of that.

RT-11 on a PDP-11/20

Can someone point me at the requirements for running a version of RT-11 (like v4 or v5.3, v5.4) on a PDP-11/20. I'm pretty sure I can get enough memory (in a BA11-K expansion chassis) but I want to know if there are other "gotchas" (like having an EAE). Also does anyone know where there is a reasonable copy of DOS/BATCH? I tried an RK05 image that's around on the 'net on one of the simulators and had little success. Did any version support RX01's?

In the haul I picked up last week, one of the advertised VT-100s turned out to be a VT-103 and I am beginning to suspect ... with John's help :) ... that the dual 8" RX02 drives go to this unit. No software but it looks like an interesting find!

DECmate-III questions

by pat＠computer-refuge.org

I just recieved a few DECmate III "motherboards" which are supposedly functional (the guy is selling more of them on eBay right now, for their Intersil 6120 chips). Before I attempt to desolder the chip, does anyone have information on these things? I'm looking for information on what each of the connectors is, and the pinout of the power connector (J2) and kb/video connector (J5?). Also, any manuals or images of software disks for this thing would be nice : ). Here's what the connectors are labelled on my board: J1 and J? (can't see a label for that one) are 34pin headers, and I'm guessing go to RX50s, J3 is probably the 'expansion connector', J6 and J4 are serial(?) and J5 is the video/kb (?). I'm fairly certain that J2 is power, but don't know what its pinout is without playing with my DMM... but I'd rather get it right the first time and *not* smoke the board... Btw, J? hangs off of the side of the board, and is a right-angle header, unlike all the rest of the connectors. +------------------------------------------+ | ______J6______ ____J5____ ___J4__ | | \___DB25P____/ /___DA15P__\ \_DE9P/ | | _____________ +-+ | | |__34pin hdr__| |'| | | J1 |:| | | |:|J| | |:|2| | |:| | | +------------+ +-+ | | | | +--+ | | E30 | | | | | DC382 | | |J? | | | | | | +------------+ | | | +--+ | +------------+ __ | | | | | | | | | E25 | | | | | | DC381 | ___ | |J| | | | | 6 | | |3| | +------------+ | 1 | | | | | | 2 | | | | | | 0 | |_| | | |___| | | | +------------------------------------------+ -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/

Dec Rainbow prehistory

I was just realizing that I gave away probably my only installed copy of the RX50.DRV shim the other month... This was an MS-DOS device driver that remapped the standard HD 5.25" drive to be Rainbow RX50 compatible. Does anyone have this or something like this that works with current MS-DOS? (or even old DOS versions, I could boot an old version to just copy files) I have a bunch of RX50s lying around I should look at before disposing of... Dave (former Mr. DECnet-DOS).

OT: hissing from a hub

by vcf＠siconic.com

I've got this 3Com OfficeConnect Dual Speed Hub 8 that is putting out this obnoxious hissing noise. It's loud enough to be annoying and add significantly to the white noise in my office. It sounds like the air is slowly being let out of a tire...forever. I've opened it up and found a capacitor with some brownish crusty stuff caked on the top of it. It also was bulged ever so slight at the top, as was another one right by it. Both are within proximity of the power connector. I didn't see any blackened spots on the enclosure indiciating that either had let out any magic smoke. So the question is, what is the most likely cause for this hissing? I've had a device before where the capacitor was causing the hiss (or at least I was pretty sure). There doesn't seem to be anything else in there that would cause the hissing (a bunch of ICs, a couple couls, a couple power transistors, etc.) Any help appreciated. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

How many of you like HP41C calculators?

Certainly not an oxymoron. I have a real soft spot for analog computers. The theorist in me wants to hear the term analog computer as a whole as describing a computing device in a different class from the sort we've been discussing. A part of me kind of wishes a different term had been adopted for these machines, but differential equation engine just doesn't have the same ring. Now if I had just had a way to rescue the EIA hybrid machine I used in college. Of course, I'd have no place to put it, but we can ignore minor details like that... Brian L. Stuart
