power cord for 11/34?

by brad＠heeltoe.com

The end of the power cord is snipped off this 11/34a I have in front of me... It has a blue wire, a brown wire and a green striped wire. I'm assuming the green striped is ground. Brown hot and blue neutral? (I think this is a standard, but I shy away from voltages above 48vdc :-) -brad

OK, who needs a DEC SF200

by tponsford＠theriver.com

It's a beast, but unfortunatly no Vax to go with it :-( Still if you want lots o' DSSI storage? It will probably go "really cheap", unless one of the usual bidders already has a buyer for it. I'll see it first-hand on Monday and will know what is really in it. It goes to auction on Tuesday. pictures: http://w3.arizona.edu/~pacs/surplus/public/sale/P0127047.jpg http://w3.arizona.edu/~pacs/surplus/public/sale/P0127042.jpg Tom

VAXstation sysgen question

by jpl15＠panix.com

I have ploughed a bit thru the voluminous online doc, and invoked SYSGEN and read thru it's help files.... but I still have no understanding of just how to make a Device known to VMS. Specifically, I want to make a 9trk tape machine (M4 Data = TE16 ?) available. Another listmember was kind enough to provide me with SCSI cables, since the M4 machine is SCSI. I tried: SYSGEN> AUTOCONFIGURE ALL/SELECT=(_list of tape dev names_) which did 'something' and returned to the SYSGEN> prompt - but attempts to ALLOC or MOUNT the dev return 'device unknown' errors, nor are the new devices list in SHOW DEV. So of course I'm (as usual) one or two GOTOs short of a Subroutine... ;} Cheers John

Mouse for a DEC ??

by r.lasbury＠ntlworld.com

I have two DEC workstations a 3000 and a 5000 and a good working keyboard but no mouse. Has anyone any experience of making a PC mouse work on a DEC? Is this feasable or should I spend my time hunting down a genuine DEC mouse instead? All suggestions, help and advice gratefully received.

Complete and assembled SBC6120 (PDP-8 clone) and front panel for sale on eBay

by bob＠jfcl.com

I'm selling off one of the SBC6120 prototypes from VCF 6.0 on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2782363270> &item=2782363270 (I decided that four prototypes was more than anybody could need :-) This is the one on the far right (sitting on the easel) in the picture http://www.vintage-computer.com/images/vcf6/sbc6120.jpg This unit includes the lights and switches front panel, black aluminum bezel for wall hanging, a 16Mb Compact Flash card for mass storage (that's the equivalent of eight RK05Js!) and a wall wart style power supply. It's all ready to plug in; all you need to add is a terminal. If you haven't heard of it, the SBC6120 is a fully functional PDP-8 clone built with contemporary (more or less!) electronics. The SBC6120 executes the PDP-8/E instruction set, includes a full 32K words of main memory and KM8E compatible memory management, has a KL8E compatible interface for an RS232 console terminal, can connect to any IDE/ATA disk drive, and best of all (as you can see from the pictures!) has a fully functional lights and switches front panel. The SBC6120 can run all standard DEC paper tape software, such as FOCAL-69, with no changes. OS/278, OS/78 and, yes - OS/8 V3D or V3S - can all be booted on the SBC6120 using an IDE disk drive as mass storage devices. Bob Armstrong

shipping via truck? any advise/war-storie?

by brad＠heeltoe.com

In a fit of madness I bid on that 11/730 government auction. And, now it appears I've won. So, how to get a 72"x60"x48" 1000lbs pallet from PA to MA? I assume the sanest thing is to high a "logistics" firm to truck it to me. I have access to a loading dock and pallet jacks so I can receive it in a sane manner. I am curious if others have done this and if they have and "advice" (like, "next time take your medication before reading email!" :-) -brad

Correct. MM is for core, MS is for chips. I was too lazy to check what I was writing. I even have MM11-LP (96 kWords) in my 11/35. I passed the morse code exam last December, and since I had to choose a new call, the postfix PDP seemed a nice one. "PDP" in morse code is not the best choice, but I just could not resist.

Old device (eg vacuum tube) documentation

by mouse＠Rodents.Montreal.QC.CA

While digging out the keyboard to scan (see my recent message about that), I noticed that I had a rather old book that perhaps some here might be interested in information from. It's an RCA reference book from 1963, and it contains a lot of data on various types of vacuum tubes and semiconductor devices of the day, >from vacuum tubes still in use today like the 6L6 I think I saw mentioned recently to picture tubes (even a few colour types) to tube types I've never heard of like "nuvistor" and "novar". There are a number of cross-reference tables of various things, indexed by various useful things. There is a pile of somewhat similar information about semiconductor devices (though a good deal less in terms of pages in the book) and a number of pages on batteries. There are then several pages of ads for devices like multimeters and oscilloscopes and signal generators, ending with a calendar for 1963 and a few pages of address-book. There are a few mildly interesting one-page things, like one giving a number of RCA sales offices, complete with phone numbers like "WHitehall 4-2900". I would take a good deal of persuading to part with the book itself. But if anyone is interested in data from it, including scans of various portions, drop me a line. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Quicky SGI Question (skin removal)

by dholland＠woh.rr.com

Hi, A quick question (should even be on topic... theoretically... ) I've a SGI Crimson, in a older PowerSeries 4D frame that I need to move >from upstairs to downstairs. Looks alot like so: http://www.schrotthal.de/sgi/4d/440_powerseries.jpg Anyways, cause its little ol' me, I need to get it as light as possible, so I don't kill myself (or drop it) trying to get it down the stairs. I did _completely_ disassemble the thing to dust it, and get it upstairs in the first place. I've already pulled the boards/drives which relieves a lot of the weight, however, I also want to pull the PSU to relieve its weight, then hopefully I can carry the "carcass" downstairs by myself. However, for the life of me, I can't remember how the devil I got the skins off to get access to the PSU. (And I'm still "googling") Anyone know? Thanks, David PS: If this isn't quite on topic, my apologies, I'll quietly go back to poking and prodding... PPS: If it is on topic, and anyone has a set of proper red Crimson skins they'd like to unload, please let me know. :-)

brew-your-own-unibus boards?

by msokolov＠ivan.Harhan.ORG

Here's my take on the issue of not being able to use standard drivers and receivers for UNIBUS and Q-bus. Aren't both of these buses old enough that DEC made devices for both of them using only discrete logic, no ASICs? If they did make UNIBUS and Q-bus devices w/o ASICs using only standard discrete logic, as I'm sure they did, what did they use for drivers and receivers? MS

The essential data is in the back of most QBus handbooks, along with data for 8640 and 8641. 8881 is a quad 2-input NAND bus driver. 8640 is a quad 2-input NOR bus receiver, 8641 is a quad bus transceiver. The driver outputs are open-collector. Bus Driver 8881, 8641: Input high voltage Vih 2.0V min Input low voltage Vil 0.8V max Input high current Iih 60uA max [note 6] Input low current Iih -2.0mA max [note 6] Output low voltage, 70mA sink Vol 0.8V max [note 1] Output high leakage current at 3.5V Ioh 25uA max [notes 1,3] Propagation delay to low state Tpdl 25ns max [notes 1,5] Propagation delay to high state Tpdh 35ns max [notes 1,5] 1. This is a critical parameter for use on the I/O bus. All other parameters ar shown for reference only. 2. This is equivalent to being capable of driving 16 unit loads of standard 7400 series TTL integrated circuits. 3. Current flow is defined as positive if into the terminal. 4. Conditions of load are 390 ohms to +5V and and 1.6 k ohms in paralel with 15pF to ground for 10ns min and 50pF for 35ns max. 5. Times are measured from 1.5V level on input to 1.5V level on output. 6. This is equivalent to 1.25 standard TTL unit loading of input. 8881 Pinout: ___ ___ | U | Y1 |1 14| Vcc A1 |2 13| Y4 B1 |3 12| A4 Y2 |4 11| B4 A2 |5 10| Y3 B2 |6 9| A3 GND |7 8| B3 |_______| While I was looking up my NatSemi Interface databook, I notice it lists the DS8640 as an exact replacement for an SP380 (quad 2-input NOR bus receiver), and an 8T380 is the same thing. An 8881 is very similar to a 7401. The main difference is that bus drivers can typically sink 50mA Iol or so at Vol, whereas a 7401 is only rated for 16mA -- about half what you would expect to need. The speeds are about the same: 7401 has faster Tpdl (15ns max versus 25ns max), but slightly slower Tphl (typically 35ns, max 45ns, albeit for a slightly lower threshold of 1.3V, versus 35ns max for 1.5V thresholds). -- Pete Peter Turnbull Network Manager University of York

4 PDP-11's found (plus RK05's) and VAX 7000 !

by waltje＠pdp11.nl

All, Looks like we will be able to save these from the Evil Melter, enough people have expressed their interest. Some points of interest: - they are in Santa Clara, CA, not The Netherlands ;-) (sorry, my German and Spanish friends) - they are in a "take em all or go away" deal; this scrapper is not one of the friendliest in the trade... still, he *does* let me go through things, which he never allowed before... - i currently dont have time to work on the systems, as I am about to go to boston, so will just get them and store them in a safe place until march, when i am back here. So.. to all who wanted some of the gear: I am going to arrange for pickup of the stuff (all of the 7 racks, including the ones with all the lab peripheral shtuff) and take out the cruft. Someone local wants to pick up the programmable power supplies saturday, so that is good ("one rack down, 6 to go!") and the digital voltmeter is also "taken". I will try to compress the stuff into 2 or three of the racks (the H960 clones from Tek) to save space. I *assume* nobody wants the Tek displays/terminals. Nobody wanted the VAX 7000, so I'll try to take some pictures of it, before it visits the Evil Melter. Cheers, Fred

scsi cables & peecee stuff wanted

by jwest＠classiccmp.org

I'm in need of two scsi cables, the ones with the 50 pin centronics connectors on both ends. One cable needs to be about 5 foot, the other cable needs to be about 1.5 feet. A 50 pin centronics terminator is needed too. Also looking for an AGP card that has a fairly mainstream chipset (so X11 will support it) that does 1024x768 in 32K colors. Nothing fancy. This stuff is only vaguely classic computer related in that I'm trying to finish off building a PC (AMD K6-2/450!) used to support my classic machines (for burning tapes, disks, etc.). Thanks!

Corvus Omninet and Apple IIe - need docs

by maya2blue＠juno.com

I have ten Apple IIe's, a Corvus full of MECC and other software. I have a 4 drawer file cabinet full of Apple eucational software, and *lots* of extra Omninet Apple transporter cards, cables, and trunk adapters. Everythings works just fine. But..... I have no documentation for the Corvus hardware or software. The hardware specs are: Corvus model 74MB7 Rev C SN 398-GN9230-P The Apple cards "Corvus Systems Transporter 8010-10969 rev E" The adapters "Corvus Systems trunk adapters A 8010-12393 01" The cables are marked "OCS II TU 6010-078681-01 low voltage computer cable" The software is "Corvus Systems Constellation III V3.0" I need *both* the software and the hardware docs. Of course, I would certainly be glad to find either one! Any help locating these manuals, as well as any helpful hints, would be much appreciated. Many tks!!

I've got to figure they got rid of them >a while back, but you never know. Yep, the console had languished at salvage for more than a decade, in a back corner. Much of the electronics has been stripped, but the structure is pretty complete and the CRTs and much of the HV is still there. The 205 carcass is still there, being stripped for gold, no cards left, just backplane blocks and coaxial interconnect. I don't know what happened to the ETA-10, but I'm guessing it was sold. --tom

Advice on electrostatic deflection CRT ?

I have what I believe is a custom CRT. It has a 12" round face, is approximately 20" long -- .. and has a second one mounted next to it, and a keyboard underneath? There may be schematics for such a device in the Computer History Museum archives if so.

TE16 capstan roller is very sticky -- what to do?

by vp＠mcs.drexel.edu

I haven't even seen a TE16 capstan roller, but since TU58s have a similar mechanism to the HP-85 cartridge drives, the following advice may be of use: 1. erd posted the following in the vintage-computer mailing list: > [...] I have used 1/2" tygon tubing from the local hardware store > (think "large aquarium hose") to refurb DEC TU58 drives (same tapes, > same capstan, same melting problem). > > I got a foot of it a few years ago and have yet to run out (even though > between HP line analyers, VAXen, and a VT103, I have nearly a dozen > drives to overhaul). 2. katie posted the following in the MoHPC forum: > In the plumbing department at Home Depot I found some stuff called > Magic Wrap, it's a roll of very thin rubber 1" x 16'.

I > also leave the capstan on the motor during the repair. 4. http://www.voidware.com/calcs/hp85rep.htm I do not recommend heat shrink tubing as it tends to come off. Test the repair by retentioning a sacrificial tape (use the CTAPE command on the HP-85) two or three times in a row. If the tubing does not come off, then it'll probably stay put for a couple of years. If you are wondering what is the thickness of the rubber on the roller, the following picture is of an original HP roller with decayed coating still in place. http://www.series80.org/Pictures/HP85-TapeDriveCapstan.jpg **vp

Compaq Portable III 3.5" disk drive

Any pointers would be helpful. Thanks. I also had a Compaq Portable III - - it had a 5.25" FDD. It left the plant 17th March 1988 - the date of my birth! It got stolen from my grandmother's summerhouse in 1999 - and the insurance company gave me 1500 dollars for it! (Disclaimer: It was my mother who 'did all the talking' to the company - I got a lot of money because of the proprietary accounting software on the machine - The check came as a surprise to both of us)

available: 1/2 tape, 7 inch reels, $6.25 each

by jwest＠classiccmp.org

I was offered 7 inch diameter 600' tape reels (1/2 inch), fully reconditioned (cleaned and actually recertified) for $6.25 per tape. I was thinking of picking up some. I really like the small reels, normal size reels are great for backup, but for OS load tapes and file transport I like the 7 inchers. A) Is this a good price? B) Anyone want me to order some for them? (obviously depends on A) Jay

Modern Tube computing

by technobug＠comcast.net

On 21 Jan 2004 15:55:40 +0000, Gordon JC Pearce <gordonjcp(a)gjcp.net> keyed in: > On Wed, 2004-01-21 at 15:43, William Donzelli wrote: >>> The problem with NOS is that the glass is slightly porous and the >>> valves >>> will have gone a bit soft by now. >> >> This is basically false. > > Well, I call it as I see it. I have literally dozens of new old stock > valves, in their original cardboard sleeves. Some are useable, some > are > absolutely shagged. It's not all just cheap brands, too. Space heaters generally decay due to the escape of gasses into the envelope. This can be caused by two mechanisms: outgassing and leakage. When the tube is manufactured care is generally taken in choosing the metals/glasses to ensure that they have a low gas content. Initially the envelope is evacuated under fairly high vacuum and baked to allow any adsorbed gasses to outgas. The longer the baking, the better the vacuum. Consequently, the cheapies will use cheap metals/glasses and shortcut the bake-out time. Finally, the tube is sealed and the getter is fired (i.e. evaporated). The getter is an active metal that you find plated around the base of the tube. The getter generates a high vacuum in the tube by combining with active gas species and trapping the inert ones. Since getter is expensive, cheap tubes go short on this item with the subsequent outgassing of the guts causing the decrease in conduction. The second mod of failure is by leakage of helium. Although this gas exists at about 5 ppm in air it abhors a vacuum and will over time leak into the tube. Glass is permeable to helium. (HeNe lasers fail due to the leakage of He. You can take a dead HeNe and resurrect it by placing it in pure helium for several weeks...). The inclusion of gas into a tube is evident by the blue glow one sees in a tube that is going over the hill. Moral: don't own tube equipment if you're in the balloon business. As an aside, during the '60s is saw a control computer being developed for the military that consisted of several hundred tubes integrated into a volume of approximately 20x20x20 cm. The "tubes" were fabricated by forming cavities in ceramic layers with beta emitters for cathodes and plates and interconnection evaporated onto the ceramic. These layers were then stacked to form the controller. The average tube was on the order of a 1/2 cm^2 or less. This baby didn't glow, but I would like to have the bucks that went into its manufacture... Claude Ceccon
