>What am I supposed to do if it becomes obvious I am not going to be able to >track the guy down? (which it has, except for the new idea of trying name >lookup directories, I do know his name and his former city and state.) You could pass them on to the next person that needs a copy. Or even start a "library" of sorts with it. You send it to someone, they use it and send it back, and you hold it until the next person needs it. Of course, that gets into copyright issues, but I'd assume either you aren't worried, or it doesn't apply, if you already "borrowed" a copy to begin with. >and hope everyone doesn't think I am some kind of miserable >lying bastard. This was an honest mistake. Like someone else pointed out, don't be TOO hard on yourself... had the guy REALLY wanted it back, he would have hounded you for it (unless he did, and you just didn't share that fact). I don't know about others, but I NEVER loan my only copy of something to anyone that I can't drive to their house and beat them until they give it back (and even then, they have to be someone I know well and trust). But I will happily loan extra copies of something, or duplicates of it. In those cases, I except the fact that I may never see it again, and I don't care... if a basic attempt doesn't get it returned, then I just write it off. Good chance this guy was the same way. -chris <http://www.mythtech.net>

Slightly OT: Ethics

by torquil＠chemist.com

So about 2.5 years ago, I bought an SGI machine off ebay and the guy let me borrow the IRIX 6.5 media. I never sent them back and contacted him like 4 months later and said "Whoa I forgot to send them back, can I have your address?" I meant to send them, but forgot *again*. I have tried to email him every 5-6 months for the past two years, but his e-mail is dead (domain name is gone) and his ebay account hasn't been used since 2002. What do I do? I am thinking it'd be okay to sell the CDs and if I ever do by some chance find him again, then I can give him the money. I feel really bad about this. Any advice? --- Thanks, Torquil MacCorkle, III Lexington, Virginia

MicroVAX 3100 M10

by mpokorni2000＠yahoo.com

In general, MicroVAX III could handle 64 Meg, though some CPU boards did not have all address lines brought out of Memory Controll Unit pins. Here my memory gets fuzzy, I am not sure whether that was the case only with those 'workstation' types or that was also a case with backplane based machines. There was an outfit that was retrofitting such CPU boards for full range of addresses and I do rememmer whether they were Stateside or in Holland. The largest Digital memory for backplane based MicroVAX III was a 32 MB board, but that came quite late in the life of MicroVAX III. The initial 'Minimum Configuration' shipments of those systems were with 8 Meg, then that was upped to 16 Meg. The 4 Meg board that is mentioned, is probably partially populated 8 Meg layout. However, there were third party boards up to 48 MB. Rational for that corkey size was that customer does not have to trow away original 16 Meg that came with machine and still fit full 64 Meg complement into two slots.

Once I removed the cover, I could clearly tell that the "chirp" is coming from the switching power supply. There appears to be no activity from the rest of the monitor, including the fact that even with the lights off, I could not observe filaments lighting. The power LED does light, however it's fairly dim - I don't know how brightly it would normally light. The final filter capacitor in the supply is rated at 180v DC. I powered the supply briefly under no-load and the output rose to 140v. With all the connections in place, it is producing about 55v - I have no idea what the normal requirements of the monitor are. This is where a set of schematics would really help (anyone ???)

(Want a few Iisi's, perhaps? A few 20MB Rodime hard drives with external actuators?) What happened with your Iifx? If you're really going to scrap the II I could perhaps be persuaded to give it a home; haven't had my hands on one since I ran one as a file server in 1991-2; somewhere I still have AppleShare and the AppleTalk Internet Router software I used back then. That was a really hot network (not) - 6 SE's, an SE30, an original LC, a Iisi, a II as a server, another II as a workstation, a Shiva Telebridge and an Avatar MacMainFrame SDLC gateway to a remote CICS host and a LaserWriter IINT. All on PhoneNet, too. Another SE was used to dial into the Telebridge at 2400BPS thru a Practical Peripherals modem. 90MB SCSI Bernoulli on the SE30 for backup. We even had a PC in on this party using a PC AppleTalk card. Ran FileMaker II for a workgroup plus Word 5, Excel, PageMaker 3, Canvas 2.1 and the Avatar software for mainframe session access. The Avatar printer emulator ran on a dedicated SE driving an OKI dot-matrix printer through a serial-to-parallel adapter as I recall. Worked fine, too. The leased-line modem for the remote mainframe access was easily as big as a Mac II; as I recall the II sat on top of it. Quite the setup. Drove our MIS guy nuts that this arrangement of odds and ends set up by an amateur - all units were out of production by then except maybe the Iisi - was stable but his Novell setup crashed every few days. I figure your Mac II and my ImageWriter LQ would make a handsome 'couple' while completely covering a good sized desk's top. Nothing like old Apple hardware - I'm still printing on the LaserWriter II I bought new in 1989. Works fine. Slowly, but fine. Seth Lewin

Couple DEC items seen on eBay

by classiccmp＠crash.com

Lost control and wandered through ePay for a bit today. A few things someone might be interested in, all DEC, all the same seller as he caught my eye with a laptop and had all these goodies listed. No affiliation. I know I've had some email conversations, not sure if I bought anything, but he seemed reasonable. YMMV. VAX 8530, single cabinet with Console 380 sitting on top, appears cabling is intact. CI interface. Guy wants $250, wonder if he won't make a deal after nobody bids... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1486&item=3091806283 "DEC Memory Array Tester". It's late enough that it's got what look like Euro connectors, but I can't guess what flavor of DEC memory interconnect it's for. Certainly post-Unibus. Has a sheaf of papers in the lid, unclear if they're docs. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=25423&item=3810462266 RK07-EF disk pack, allegedly new in box. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=3756&item=4125693956 Share and enjoy, --Steve.

Help with Atari 1050 disk system - success!

A standard PC drive runs at rotational spindle speed of 300 RPM. According to the FAQ's and some of the documents included with the various Atari<>PC disk transfer packages that I have looked at in the past couple of days, the Atari 1050 drive runs at a nominal speed of 288 RPM. The disk copying package that I managed to download and boot included a drive speed test - my drive weighed in at 287 RPM, so it would appear that this information is correct.

Looking for Atari SC1224 monitor schematic

by dave04a＠dunfield.com

Hi Everybody, Picked up another 520ST (same flea market as 1050 drive) - it's a later edition as it has the power supply and floppy drive built in like my 1040ST. My other 520ST requires an external floppy and drive. Anyway, the machine itself works fine, however the Atari SC1224 monitor that came with it does not. I can hear it "chirp" when I throw the switch, suggesting that the horizontal oscilator is running, however I never get any light on the screen - no apparent "static bristle", so there may be no HV, but I can't tell for sure haven't opened it yet. Anyone got a set of schematics for the SC1224? Btw, does anyone know if the internal floppy drive of a 520ST is a single-sided drive like the external SF354 drive? Or a double sided drive like is in the 1040ST?

Help with Atari 1050 disk system - success!

by dave04a＠dunfield.com

Hi Everybody, (Hi doctor Nick) I discovered that I had a couple of power supplies all along. I remembered this afternoon that I have a couple of Atari 1010 Cassette drives tucked away, so I dug em out and sure enough: Atari 9v 31va supply - just what the doctor ordered. I also found a program called WRITEATA which tries to write Atari format disks on a standard PC drive. It has trouble due to differences in drive speed and the fact that it can't do 128 byte sectors, however I was able to get it to write 130k "enhanced format" 1050 disks. Most Atari DOS images I've found are 90k which it can't do, however I found one called "TurboDos" in a 130k image, and was able to write it and it booted! It booted and then crashed on the 600XL I was originally testing with, however I noticed a message indicating "XE RAMDISK LOADED" ... so I tried a 130XE and everything worked - it comes up in some sort of menu program written in basic, which I could exit (to BASIC), then use "DOS" to get to DOS - so my drive does work! I also found a 130k disk copying disk that works, it appears to have a German version of Atari DOS 2.5 underneath it. Thanks to everyone who helped me figure this out.

MORE 1802s!!!

by rigdonj＠cfl.rr.com

I made a major score of 1802s recently. A couple of weeks ago I went a scrap place and found some old traffic controllers. I opened one and found that they all used socketed 1802 CPUs.

Here is a not so good picture of what they look like <http://www.signalfan.freeservers.com/controllers/transyt1.htm>. FWIW I also found a couple of Eagle controllers and I checked them, they used 68008 CPUs. OK, Now go find those controllers! Joe

Need help with Atari 1050 disk system

Last night, I took the drive apart and checked it out (all looks good), I could see a rectifier on the input, so I concur that it is AC. I cobbled together a 9V ac supply and powered it up - I did observe exactly what you indicate, the drive comes on, spins, and the head steps out and back >from and to track zero. >The software that came with the 1050 only made it a "dual density" as they >called it drive.

If I connect the drive to a computer, I observed the following: With not disk in the drive, the computer rapidly issues "Boot error" messages continuously, and the drive remains stopped. With a disk in the drive (not an Aari disk), the drive activates, and the computer issues "Boot error" much more slowly - clearly it is trying to read the unformatted disk. So - I think the drive is working. I was unable to find any way to get the system up with the drive connected, so I don't see how there could be DOS in ROM as some people have suggested. Any ideas? Is it possible to do anything with the disk without a DOS boot disk. This sounds like a very simiar arrangement to the C64 1541 drive, except that the commodore boots "normally" in BASIC and you can send commands to the drive via BASIC file operations - the Atari appears to want to boot from the drive before you can do anything.

Need help with Atari 1050 disk system

by dave04a＠dunfield.com

Hi Everybody, (Hi doctor Nick) Picked up some more old Atari equipment at a flea market this weekend, among other things, I got a 1050 disk drive. I have not had one of these before. #1) Can anyone tell me the power requirements of this drive? (voltage, polarity, current) - this information should be on the label of the power supply - as you probably guessed, I did not get the supply with the drive (had an Atari computer supply in the box). #2) The box says "Includes DOS 3 Double Density Disk Operating System", but there were no diskettes in the box at all - presumably I need some sort of boot disk... Anyone out there with one that can make a copy or send an image (Can Atari images be read/written on a PC's drive?) Any help would be greatly appreciated. Regards, Dave -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Vintage computing equipment collector.

save the Mac II (original)

by I.Savvidis＠cmc.ase.gr

Dear Mr. Allain hello. If nobody else is interested I would like to have it, if you don't mind sending it to Fairfax, Virginia. I'll pay of course for packing and postage. Thank you in advance, John Savvidis -----Original Message----- From: John Allain [mailto:allain@panix.com] Sent: Monday, April 19, 2004 6:58 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: save the Mac II (original) Would somebody please take my Mac II? I saved it from being scrapped at the office because of it's history, in that it was Apple's big redesign, the first machine of the new line -- one that completed with IBM's PS/2 line and argubly was a greater success. I'm not a big Apple expert but it just seemed if you were going to have a few Macs that this model would be in the top 5. This one comes with a HiRes graphics card, matching Ikegami monitor (17" but compact) cables, software, etc. They don't seem to be that common, when you strip away all the variants, I haven't really found a place to get this original model. Help save the classiccmp. John A.

by vax3900＠yahoo.com

My friend told me that they are going to get rid off a HP E-series computer from their storage. It is a big box with two rows of switches on the bottom half of front panel. I am a vax guy and need some $$$ to invest into my 3900. Do you guys think it worths to epaying it? Thank you. __________________________________ Do you Yahoo!? Yahoo!

Does anyone have National Semiconductor's Appnote AN-359?

by dickset＠amanda.spole.gov

I have this INS8073-based board with four TIL-311s, an 8255, a 6116 and a socket for another, an 82S23 PROM, and an MM58174A. The MM58174A is a clock/calendar chip for which I can't seem to get the appnote for. Google reveals an old location at the Nat'l Semi webpage (it has been removed from their appnote dir), and a single reference at http://www.nalanda.nitc.ac.in/industry/appnotes/Natsemi/AN-359.pdf which refuses my connections (could be down, could be blocking U.S. access; not sure which). I don't care if the Digital Library of the Calcutta Technical Institute is up or not; all I'm after is the app note for the MM58174A. Does anyone on the list have the file 'AN-359.pdf'? Thanks, -ethan P.S. - I realize a picture speaks a thousand words, but does anyone recognize the device I've described? It was a gift from someone, years ago. I brought it with me both as a source of TIL-311s and because it's a complete INS8073 SBC. From what I can gather so far, it's pretty close to the Nat'l Semi reference design, down to using a 741-style RS-232 converter for the console interface. The only useful markings on the PCB are "MC-1N REV-A". The layout of the TIL-311s and the four pushbuttons on the corners of the front panel suggest to me some sort of digital timer. There's a 2x5 jumper block on the front that appears to be input power, serial in/out and a few of the CPU flag pins (F2, F3). There's a 1x9 jumper block on the back that seems to be just options, not I/O, but I haven't traced the whole board out yet. P.P.S. - in case you don't recognize the CPU part number, INS8073, it's a microcontroller with Tiny Basic onboard - you wire on a level shifter, an SRAM and an optional ROM, and _bang_, a microcontroller with a built- in development system. It's the same processor used in the RB5X robot. I have had this board for years, and last year, I picked up a few CPU chips on ePay for a few bucks each. They are one of the many classic toys I brought with me to play with through the long, winter night. -- Ethan Dicks, A-130-S Current South Pole Weather at 18-Apr-2004 13:50 Z South Pole Station PSC 468 Box 400 Temp -70.8 F (-57.1 C) Windchill -94.5 F (-70.3 C) APO AP 96598 Wind 6.2 kts Grid 074 Barometer 689 mb (10289. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html

TDC1007 / 1007 / TRW / Rare TRW Processor ?

by Innfogra＠aol.com

I have seen some of these before. I had some like this from TRW. Not sure of the numbers though. I remember the TRW was printed on a piece of aluminum which was glued on top of a plastic chip. IIRC one I peeled apart had an AMD 2901 underneath. Most did not have anything printed on the plastic underneath. Seems TRW was quite propriatary. I also had some that I thought were 68000s underneath but with absolutely no markings. We had to take the aluminum cap off before they could go into scrap. Never saw one glued to silicon or ceramic. 2901s were at the heart of some early computers but is not worth the $175.00 that the seller is asking. Paxton Astoria

I'd like to make this available, but I have not >done so due to the copyright question - posting a published book which was sold >on it's own merit seems less legit than manuals which came with hardware. >Anyone have any thoughts/experiences on this? A quick follow-up to this before anyone "jumps" on me - I would not even think about posting something which is still available from standard sources - I have not checked to see if you can actually still buy an A2 reference manual from anyone - perhaps there's someone with a warehouse full of them? As noted above, this is not something that I am currently considering. This is more of a "distant future" question - at some point the original material will not be generally available (this may already be the case for some of it), and people wishing to learn about these historic machines will have to either borrow it or steal it (photocopy/scan etc.) - as books get older, rarer and more fragile, borrowing will become harder and harder, as will physical replication. Are there any procedures in place to allow this material to be preserved, or does it just "die off"? Many of the manufactures of obsolete computer hardware/software that I have been able to contact have been very helpful. For example, when I asked Dr. Grant, co-founder of NorthStar computers if I could post the NorthStar OS & software (under my simulator) and scans of NS documentation, he responded "North Star is defunct so there is no problem whatsoever. Have fun.". I've had similar responses from a number of other people who "own" dead computer companies. Books however are a different matter, with published books, you have both the Author and the Publisher with interests in the book. I think it would be a lot more complex to obtain similar permissions, but to be honest, I have not tried - anyone here ever gotten permission to distribute the content of a published book?

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

The proper way to make a real PDP-11 (or VAX or any other Classic computer) available to everyone who wants one is put them back in FULL PRODUCTION. Not just hobby, but real full production and commercial sales (for a reasonable commercial price). I'm working on a new VAX chip and will soon be putting VAXen in full production. I can't do the same for PDP-11 because it just isn't my area of expertise, but my close fried, comrade and associate Stacy Minkin is more on the PDP-11 side and wants to build a new PDP-11 using FPGA technology just as much as I want to do it for the VAX. If you want new PDP-11s, E-mail him at stacy(a)ivan.Harhan.ORG and tell him that you want to buy a PDP-11 and would be willing to pay a fair commercial price and possibly finance the NRE cost. Stacy is a real engineer with a vision just as grand as mine, so given enough people willing to buy this stuff (for real, commercially, just like in The Days when it was new), he and I can build The Real Thing: real microcoded CPU, honest-to-Daemon UNIBUS, etc., not a poor man's emulator.

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.

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

Apple IIC+ Pointers on getting programs to and from machine.

Hi Ron, To transfer images from my Franklin, I built a serial card using a 6551 UART running 19200 bps, and wrote a set of programs for the Apple and the PC to transfer images over a serial link - takes about a minute and a half as I recall to transfer a disk.

Reading my previous post it looks like it came from Zane. Sorry I forgot to sign it. I do like my Optio camera but it shows some of the limitations of earlier cameras. It is probably the last of it's line. Lots of manual options is one of the reasons why I like it. The limitations are two "f" stops and only 100 & 200 ASA Paxton Astoria, OR.

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!

SSMEC?

by rigdonj＠cfl.rr.com

Does anyone know of any computer related meaning for the name/acronym SSMEC? I've found some Honeywell H316 parts that are marked 'for program SSMEC'. I've found one definition of SSMEC but the meanng seems to be a little too fantastic. Joe

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
