Data General boards, HP stuff, rainwater damage?

by shirker＠mooli.org.uk

Hi folks, Rescued the following last night, amongst some other stuff: * 3 large cards from a DG Nova system (?) around 16" square. - one marked "BASIC IO CONTROL DGC NOVA (C) 1968 DATA GENERAL CORP" This has a small board numbered 70-00196 which appears to have been retrofitted, judging by the number of blue wires running to it from the board itself. This seems to be in good shape. - two related ones, one marked "TELETYPE PLOTTER WITH ALPHANUMERICS ISSUE 1" and then in the top corner "LINK SYSTEMS LTD MADE IN ENGLAND" 2 ICs are missing and one is smashed open, and this board has a 3" or so rip in it - the other marked "TELETYPE PLOTTER WITH ALPHANUMERICS OPTIONS/Q.E.D." 2 ICs are missing from this one. 2 presets mounted on one side of this board look the worse for wear. * Motorola VME? board of some kind. 68020 CPU, 2/3 of VME height (has 2 of the VME-style connectors on one side), 50-pin IDC header on the opposite side, along with 2 switches, 2 red LEDs and 2 green LEDs. * "Opus" badged ADC MM-211 mono monitor, slight screenburn at bottom of CRT, has a DE9 connector with only 6 pins fitted. CGA/EGA? The above are free to good home - you pay postage or collect from near Leeds, UK. Not sure whether these are worth anything or not: * 2 BOC Edwards vacuum meters, one marked "PENNING 8" and one marked "PIRANI 11". About 4"x6" faces, panel mount, mains powered. Each one has a switch to select between ranges, and inputs on the back for the metering hardware. * Watkins-Johnson WJ-269-I Low Noise Amplifier, 2.3-4.5GHz in weird cylindrical black case, 110-120VAC. * Marconi "TF 868B Universal Bridge". Seems in nice condition except for what look like two sets of concentric knobs on the top panel of the unit have been smashed, and the top plate is cracked where this has happened. Make me an offer I can't refuse ;) I'd like Real Money(TM) for the following: * Farnell PU164A rack-mounted telco PSU, provides +5V, +/-12V, -50V, all @ big amps by the looks of the output busbars that were attached to it. Has mains lead, which is just as well as it uses a Bulgin 3-pin mains connector rather than an IEC320 socket. 2U I think. Weighs 12.5kg according to a sticker on it. * Half height (waist height) 19" rack, in fetching chocolate brown colour with folding handles on both sides. Has a piece of kitchen work surface on the top in an attractive pine finish ;) Put your servers in your kitchen? (The ultimate in domestically-acceptable 19" racks maybe?) Has big castors for ease of shiftage. Again, please make an offer by email if you're interested, otherwise they hit ePay. And the following I'll most likely keep, but anything anyone can tell me about it would be much appreciated (specifically what's needed in terms of hardware/software to control it): * HP computer-controlled test & measurement system, comprising: - 61001A System Power Unit - 61010A Digital I/O - 61011A Relay Mux - 61012A Dual Voltage DAC - 61013A Digital Multimeter - 61014A Function Generator - 61015A Counter - 61016A Digitizing Oscilloscope - 61017A Relay Actuator I had thought these would be HPIB, but the cable (26-way ribbon) looks nothing like it. Any/all info about these would be most handy. And now to the "rainwater" bit - I found all this in a skip (or "dumpster" for those of you of a North American persuasion) which was outside, so these things have been being rained on (except the telco PSU, which was in the rack and so will have been protected from rain). I haven't opened any of them up yet to check for corrosion, but I've spotted some rust on the edge of the casing of the 61001A already. What's the best way to deal with this stuff to prevent any further damage, and rectify (if necessary) any that the water has caused, if indeed it's caused any at all? Other than obvious corrosion, how would I tell? None of it was lying in standing water, FWIW - I don't think there was any in the skip, and this stuff was all well above it. TIA, Ed.

save the Mac II (original)

by SUPRDAVE＠aol.com

Well, the Mac II is rather big and heavy although I guess you can stack other Mac models on top of it. I prefer the toaster macs since they are what people think of when you say macintosh. Actually the IIfx is a nice machine. 68040 40mhz and decent fx performance. uses special memory though. witchy(a)binarydinosaurs.co.uk writes: It would be for me, but I've already got one.

PDP-11 price guides

by pat＠computer-refuge.org

Has anyone worked on, or thought about working on, a "price guide" specifically for PDP-11 (or PDP-8, or VAX) hardware? I know of Michael Nadeu's book for microcomputers (which I keep meaning to buy), but this is really a different realm of things, as you can configure (for example) a PDP-11/23 in a whole lot more ways than you could with a C-64. I've thought "hmm, this would really be handy" a few times before, but haven't had much time to sit down and work on it. It'd be nice if I could keep it up to date, and use multiple data sources (not just past marketplace.vintage.org sales), including eBay and semi-private sales. Also, a "rarity" quantity of some sort would be useful, and could just be "very rare" for, say, the preverbial 11/74 (the one that's supposedly 2 CPUs), to "common" for an 11/23. Thoughts?

Great HP stuff on Ebay

by jwest＠classiccmp.org

I thought long and hard about posting this on the list, not wanting to draw attention to it as it's in an odd category on Ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3092118791&category=6403… It's an HP 7900A drive, looks to be in great shape, and includes 7 pieces of media. After a long pause I decided I had enough of these. Odd, there was a day when I'd give my left arm for one of these, now I have a couple. So Ashley, here's an example - keep looking and the stuff does show up. Someone please get this drive and don't let it go to the scrapper! Also, make sure to get the 13215A power supply for this drive the seller also has under a separate auction, the drive is worthless without it. And do NOT use the media for this drive in a 7905/06, or vice versa, they look the same but you'll be really sorry :) If no one bids or wants this drive I may bid on it just to save it but I'd rather see someone else get it. The same seller is also selling a pretty nice 1000E cpu, a 12979 I/O expansion unit stuffed with cards, and another auction with keyboard and some cables. I can tell the 1000E cpu does have the right controller in it for this drive (dual 13210 interface). But please don't anyone bid on the DSU he has up in a separate auction, I want that very badly!!! :) Jay West --- [This E-mail scanned for viruses by Declude Virus]

PDP 11/40, VT50 or VT52, LA36

by wacarder＠usit.net

Does anyone on this list have any of the following items that they would be interested in getting rid of: PDP 11/40 with rack and RK05 drive(s) VT50 or VT52 DecScope LA36 Decwriter RK05 pack with RSTS/E I would like to attempt to reconstruct the computer that my friends and I used in college from 1975-80. Our former professor who was also director of the computer center and is now retired has indicated that he might offer some assistance in reconstructing the environment if we can find a PDP 11/40. Our college junked their 11/40 in 1989 or shortly thereafter. The new generation of computer people there "cleaned up" old junk and threw away anything that was left from the 11/40 that we knew and loved. We have created a pretty faithful replica using Bob Supnik's emulator and have it available via TELNET on the internet. Several of us had complete prints >from the late 70s of all the source programs on the system. It was running RSTS/E with Basic Plus. It took a while to find someone with a soft copy of the Basic Plus version of ADVENTure, but I was able to get a copy from someone who was in Project Delta and have loaded that to our RK05 disk image for our simulated 11/40. We would like to get our hands on the real hardware so we can feel the heat and hear the fans whirring once again! Thanks for any and all help that anyone can provide! Ashley

TRS-80 model 12

by yakowenk＠yahoo.com

I've got a bashed up TRS-80 model 12 sans keyboard, so... Can anybody out there give me the specs for the keyboard connector? Looks like a 5 pin DIN, I guess a serial connection of some kind. I need both the wiring (which pin is which) and the comm specs (baud rate, etc.). It is probably the same as the keyboard for the model 2 and model 16, in case that helps. Alternatively, if anybody has an appropriate keyboard to spare, that would be great too! Also, while I'm asking, can anybody recommend a kind of glue for putting the shell back together? The poor thing took some damage in shipping. It looks like some kind of resin. Acetone did not seem to have any effect on the stuff. I've put a few bits together with "super glue" (cyanoacrylate), but have doubts about it holding very well. Thanks! Bill. __________________________________ Do you Yahoo!? Yahoo!

OT: Other collecting activities? - Digital Stereo camera

by Innfogra＠aol.com

In a message dated 4/17/04 2:59:57 PM Pacific Daylight Time, healyzh(a)aracnet.com writes: Some interesting things for the traditional Stereo Card format could probably be done with a properly hacked pair of digital cameras. I'm not sure what might have been done along these lines. Photography in one of my avocations too. Last "buy nothing day" I bought a Pentax Optio 430RS digital camera for an upcoming trip to Mexico. To my surprise it has a stereo mode and came with an interesting stereo viewer. It looks like it will be fun to play with. First you shoot one pic, move the camera slightly and shoot the second pic. They are both recorded on one frame. You then print the pic on a normal color printer which prints the two images on one sheet of paper. Comes with a chart on how much to move the camera for a given focusing distance to get an optimum stereo effect. The viewer is a pop together piece of translucent plastic which you then set on the print and look through the lenses to see the stereo picture. Folds flat. I was surprised to see stereo in the camera and a viewer in the box. Someone high up in Pentax has a stereo bug. I took a couple of stereo pics. Enough to see there is a learning curve. Didn't use stereo on the trip. Turned out to be a good first digital camera for the trip, though.

TI Bubble Memory?

by rigdonj＠cfl.rr.com

Today I found a couple of multibus cards made by TI. One of them is marked TM990/210. In addition to a TI TMS9916NL LSIC, it has six large yellow "blocks" on it that I THINK may be bubble memories. They're about 1 1/4" square and about 7/16" thick and are marked "TIB 0203S, 23May80 -1, MSK=627573, 8B, 958-S-40, 24-164-11". They're in flattened out metal cylinders with a black epoxy looking material in the center. There are seven leads coming out of each end and there is what looks like a small plastic transistor clipped to the side of the package. It looks like a transistor but only has two leads so I'm guessing that it's probably a temperatrure sensor. Does anyone know if these are bubble memories? I've had TI bubble memories before but they didn't look anything like this. Anyone know what these cards are? the second one is marked TM990/310. It has three TI TMS9901s on it along with many SSI ICs. Joe

PC boards and software

by charlesmorris＠direcway.com

>If you can settle for 4 x 6 inches (roughly), you can get everything >needed for $125. That seems not too bad to me, for software I actually like >to use, as opposed to "can get by with". Actually 160x100mm (Eurocard size) which is 6.4 x 4 inches... never seems to be quite big enough! I bought the nonprofit version for $125 or so which has that limit. >Agreed, the $1200 (that I paid) for the unlimited version is a ton of money >for software. (Maybe you are the target audience for PCB123 :-).) $1200? I thought the top of the line was $495 (which IMHO is still a ton of money). Meanwhile, for PCB shops I have been very happy with Olimex (www.olimex.com) in Bulgaria. If you're not in a flaming hurry (airmail takes about 10-12 days but is only $8) they will make a Eurocard-sized two layer, silkscreen, solder masked board for $26, directly from your emailed Eagle .SCH and .BRD files. Turnaround time is 3-5 days not counting the airmail. -Charles

I just acquired a Power Book 170. Hopefully it is old enough to be on topic here. It looks to be in great physical shape but I have a few questions. When I plug it in there is a mouse pointer and a small blinking diskette. 1. What do I do next? What disk is it looking for? 2. Should there be a hard drive in this computer? 3. If there is a hard drive why should it be looking for a diskette? 4. Battery does hold a charge ================================= Gene Ehrich gehrich(a)tampabay.rr.com

Write protect tags

by dwight.elvey＠amd.com

Hi I just saw something interesting on ebay. Now for years, I've been carefully placing the tags on the disk nice and square. I even pre-bend them so that there is little or no force pulling them off the surface. Still, one or another will eventually snag on one of the corners and lift up. Well, I just saw a disk with the tag mounted such that it was diagonally mounted( looks like a little triangle >from each side ). There are no parallel edges to catch on things as one slides the disk in and out. The sharp corners that might catch are on the edge of the disk and unlikely to cause the tag to lift. Has anyone else tried this? What do you think? Dwight

DEC VAX 785 and PDP11/70's in Kansas City

by mmcfadden＠cmh.edu

I just got word from a friend that a company in Kansas City is planning to dispose of the following. DEC VAX 785 in three 6' cabinets DEC PDP 11/70 in ten 6' cabinets, this may be two computers 4 RM03 disk drives 2 TU80 tape drives Other disks for VAX That is what they remembered without actually having a list. I'm trying to set up a time to actually see them. Here is the other information I have received. There is a company from Topeka that will take them away if they are paid to remove them. The 785 was running 3 months ago when they erased all of the media. It has been about a year since the 11/70's were on. They are not currently running. They are checking on the legal requirements that they may have to go through to dispose of these units. They are worried about making sure they aren't legally libel if somebody dumps them improperly. Whoever takes them away may have to be a GE approved vender. I'll keep everybody informed. Thanks Mike

Vector Graphic Model SD-5031, aka Vector MT

by donm＠cts.com

I have the Vector Graphic machine listed in the subject line. It is a tan S-100 box with black panel, and a tan monitor that carries a logo plate that says "VECTOR MT". This Vector is equipped with a hard drive and a single DSDD 100tpi floppy disk drive. The hard drive controller (ST-506 interface) and the floppy drive controller (16 hard sector) are contained in the same S-100 card. The card etch dates it as 1980, and a silk screened note says it is a "FD & HD Controller". Despite considerable time spent with google and other search engines, I have been unable to locate any information of value about this machine. I have been using it quite successfully for some time. However, very recently, access to the floppy has become most erratic and the usual result is the error message "DRIVE NOT READY". However, on occasion it is possible to read the directory and read some of the files on an installed disk. I suspect that the cause of the problems are with the controller card, but without documentation I hardly know where to start any troubleshooting. So, to the point of all of this! If anyone has any documentation on this machine that they would be willing to share with me, please contact me either privately or publically. It will be highly appreciated!!! - don

ra90 - actuator pin sticking?

by brad＠heeltoe.com

I should probably search the archive, but has anyone experience with RA90's? I got one recently and when I powered it up (after a thorough cleaning) it faulted with E9. I have (thankfully) several manuals for this device and it seems to indicate the solenoid which "pulls the pin" on what looks like the voice coil head motion thing may be sticking. "head motion thing" - that's a techinical term. (ok, if you must know, I bought it on ebay, but for 2 orders of magnitude less than the truck full of pdp's :-) I've decided that I like RA90's better than RA81's :-) mostly because I can lift them :-) The drive spins up and I can run the diagnostics. The simple tests work. any thoughts? -brad

FS/FT: MTI Stingray SCSI - HSC for CI VAX Cluster

by jkunz＠unixag-kl.fh-kl.de

Hi. I have a MTI Stingray SCSI HSC. I.e. a 3 U 19" rack mount box that has a VAX CI (4 x Coax) interface on one side and a (HVD) SCSI interface on the other side. It appears on the CI as single cluster node with several attached disks, like a real DEC HSC. Together with the HSC come four SCSI drive canisters. Each of it can hold at least two SCSI disks. The SCSI drive canisters also contain some electronic to convert the 8 bit single ended SCSI bus of the disks to the 8 bit HVD SCSI bus of the Stingray HSC. There is also rack mount stuff for the drive canisters. So you can get a complete CI HSC with 7 SCSI disks in 9 U 19" rack space. I have a MTI CIQBA Qbus to CI adapter also. Yes, a Qbus to CI adapter. It needs special (VMS) drivers that you can get from MTI. There are no disks in the canisters. I had to leave the disks at the company where I got this machinery. There where some Seagate and Micropolis disks in the range from 2 to 4 GB in the canisters. I suspect that 7 x 4 GB is sufficient for a small home VAX cluster. ;-) Unfortunately I don't have any cables, so I can't test this. All I did was to plug in a MMJ cable to the console of the Stingray SCSI HSC and play with its firmware. I would like to trade SCSI HSC + drive canisters + CIQBA for some other nifty equipment, preferably DEC, but I am interrested in any *ix stuff. (Even if it is younger then 10 years. Special Interrest: SGI Octane CPU mudule > 300 MHz R12k or Vpro GFX or HP9000 Cxxxx. ;-) ) -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

Things to do in Detroit ~April 24-25?

by bill＠timeguy.com

Hey gang. My mate and I are going to be in Detroit over the weekend of April 24-25 and I was wondering if any of you know of any technological (or just interesting) events or locations we should visit while we're there. We have some flexibility in arriving a few days early and/or staying a few days late, so anywhere around that weekend would be fine.

help needed with Fujitsu M244x reel tape drive

by cheri-post＠web.de

Hi all ! Yesterday, I got the hand on a Fujitsu drive model 2443 (rack version). The drive seems to be in a good shape. The only problem is, that the front door with the control panel is missing, I figured it out with the help of the manual on Al's site (thanks once again, Al !!). Unfortunately, the manual doesn't contain schematics of the drive, so that I could rebuild a control panel, as it just has several light indicators and some switches. Does anybody have schematics for the control panel of this beast or a panel he would like to sell or get rid off ? Any help is appreciated Pierre ____________________________________________________________________ Der WEB.DE Virenschutz schuetzt Ihr Postfach vor dem Wurm Sober.A-F!

disk drive

by rbennett＠wbbjtv.com

I was searching for info on a sony floppy and ran across your website. There was a question on it that was exactly what I need to know. I have a piece of equipment that uses 2 floppy drives, not a pc. They are Sony MP-F52W-00D which I can't find anywhere. Sony has one available for $525 which is a little expenbsive for a 3.5 inch drive. Can you tell me anything about these drives, ie, what type are they, and are there any current drives that would replace them. Maybe there are some still available somewhere. Tahnks
