[CCTECH] LIST ADMIN

by jwest＠classiccmp.org

Greetings fellow classiccmp'ers For the next few weeks or so - I've decided that I need a total break from list administration - a "vacation" if you will. I'll still be on the list and read it (the threads that interest me) actively as always, but ALL list administration/moderation/management duties need to be temporarily handled by someone else for a bit. Effective immediately any questions, comments, requests, suggestions, complaints, etc. relating to either the cctech or cctalk lists should be directed to Jeff Sharp. During my "list admin vacation" he is to be considered completely empowered to make any and all decisions relating to either cctalk & cctech. I have asked him to check with me before implementing any really major changes, as I will definitely be taking list administration back over in the near future. This will also allow some renewed focus on getting the list FAQ whipped into shape, some much needed changes to the classiccmp website, and yes, the classiccmp mailing list archives getting straightened out (and searchable). As a side note, once I get back from my "vacation" I will likely need a few volunteers to help approve non-member postings, etc. I try to do that many times a day right now, but it would be nice if a few other people checked too once in a while to ensure things are timely. Regards, Jay West _______________________________________________ cctech mailing list cctech(a)classiccmp.org http://www.classiccmp.org/mailman/listinfo/cctech

MS-DOS CD Burning Software and MAKEISO

by mythtech＠mac.com

>Burning both audio cd's and um, archival copies of >Playstation games (they were one of the first/best apps to do DAO copies >back when >the PSX first came out). What luck have you had in duping a PSX disc? Does it work native or do you still need a "mod" of some kind on the PSX deck? I ask because I am still on the search for a non-"mod" way of doing backups. And honestly, I am really only looking to do backups (no really I am). My nephew likes to borrow my PSX discs now that I don't really play them much any more, only he doesn't seem to grasp what a jewel case is, and more often then not, I would get them back so scratched they would no longer play. So I am looking for a way to backups so I can go back to loaning him games and not worry about them being destroyed. -chris <http://www.mythtech.net>

[CCTECH] OpenVMS/DEC Alpha question

by classiccmp＠mail.vintage-computer.com

I'm not sure if this is yet an appropriate question for this list, but it has to be close. I have a DEC Alpha 1000/266 (nearly 10 years old, right?) running OpenVMS 6.2 and I'm having what should be a simple problem with it. . . The system boots to the console fine. From that point, when I boot from the boot device I get an error indicating that there is insufficient disk space on that boot device for one or more processes. This error cycles and the machine never boots to the operating system, so I'm never at a point where I can clean up the offending disk. I know there has to be a way to fix this. I'm sure it's probably really simple, too. I'm just not familiar enough with this operating system or machine to know what to do. Are there any OpenVMS sages out there with any suggestions? Erik S. Klein _______________________________________________ cctech mailing list cctech(a)classiccmp.org http://www.classiccmp.org/mailman/listinfo/cctech

What is this? Looks like maybe a VAX of some sort..

by Innfogra＠aol.com

The pallet in the upper right of the second picture are the three UPSs. The Pallet in the upper left of the second picture is the HP 7820? Which I think is actually a 7920 50 Meg removable pack disk drive. My 1981 HP catalog lists them at $14,000 to 18,000 new. The pallet on the bottom right of the second picture is the HP 2608 printer, a 400 LPM printer. In 1981 list price was $9,900. The pallet in the lower left of the second picture is a printer in a crate. It does not look like another HP printer from what little I can see. I think the first picture is a MicroVAX system with the RA Disk drive on the top. I think it is the one listed at $154,000+ and called disk memory unit.

DEC 3000/800 diag LEDs

by rschaefe＠gcfn.org

Anyone know where I might be able to find out what the diag LEDs on my new '800 are telling me? I haven't been able to find much googling, but I might not be using the correct incantation. The LEDs stay on FD. I've tried with and without the red shorting jumper in the printer MMJ, with a vt320 on the printer MMJ, and with a vt320 on the DB25 port via an H8575-A both with and without the jumper. I do have a 3W3 cable to try the PMAGD-AA, but without a keyboard and mouse I really don't want to drag out the 21" monitor unless I have to. On a side note, what kind of keyboard and mouse does this use? Something compatible with an LK401, as in all I need is a little adapter box, or is it more complex than that? Bob

The Future End of Classic Computing

by mythtech＠mac.com

>To go back to the hammer for a moment, if I go out and buy a hammer and >bash somebody's head in with it, then I am guilty of murder. The company >that made the hammer, and the shop that sold it to me, are not. And >that's how it should be. Scary thing is... here in the US, it doesn't seem to work that logically. People have been sueing gun manufacturers off and on because they made the gun that was used to kill someone. I don't know if anyone has WON a suit, but I do know the suits have been filed (and win or loose, you are costing the gun maker needless legal troubles). Sueing people has become so much the norm here... that the government has had to step in and offer insurance backing for the companies cleaning up the world trade center... because the companies know ALREADY that there will be lawsuits when they are done, and without insurance, they know they will be sued into bankruptcy. AND, since it is such a known fact that they will be sued... no insurance company was willing to insure them, which meant they weren't willing to do the work... so the government had to step in and offer backing. F-ing scary! Remember, this is the country that awarded 3 million dollars to a lady because she put her hot coffee in her lap, and then spilled it... and was able to sue McDonalds because the coffee was too hot and it burned her (yes, there is more to that story, but the fact that she was even able to get to trial is just f-ed up... where is the personal responsibility in this country?!?) -chris <http://www.mythtech.net>

[CCTECH] Cards to Identify

by Andreas.Freiherr＠Vishay.com

Hello again, not quite the kind of things I am collecting, so I need help with finding out what precisely this is, and if somebody might be looking for it. I saved a couple of boards from getting scrapped, and if nobody wants them in total, I'll be happy with the chips alone (all the significant ones are in sockets, so I needn't even solder to harvest ;-). So, heads up please if you know something about one of these boards or want to have one. Sorry, no pictures available (yet). According to date codes, all of the boards must be from late 1983 or 1984. The boards _look_ OK, but I cannot test any of them. 1) Ungermann-Bass ISA board, the old extra long format (approx. 340mm or 13.4"), appears to be a 2261A type Ethernet adapter (?), has 18 DRAM chips, Intel 80186, C82586, NEC D8255, 24-pin chip with heat sink (glued on, so I cannot read what's on the chip itself). At the panel, there is a 15-pin sub-D female connector with posts for retaining screws (didn't someone mention lately that some manufacturers had different opinions about the slide-lock retainer for AUI interfaces?) and a red 5mm LED. 2) Ungermann-Bass motherboard, approx. 385mm * 305mm (15.15" * 12"), marked "LPB3 6600" or "LPB3 MODEL 6410", with Z80A CPU, 2 Z80 CTCs, 64kb DRAM (32 * 4116), EPROM (I guess a 2716, did not peel off the sticker yet). Near the center of one of the long edges is a 10-pin power connector: +5, +5, GND, GND, +12, -12, GND, +24, -5, GND. Along one of the short edges are three 50-pin Berg-style connectors (no recognizable description, but two of them appear to be driven mainly by a bunch of 74LS374s). At opposite corner: 10-position LED array, 8-position switch array. Along the other long edge, an I/O board can be fitted, and there are two different boards fitted to the two motherboards I have: 2a) "MODEL 6402A": 2 * RS232, female 25-pin sub-D connector, labelled "SERIAL PORT 1" and "SERIAL PORT 2"; 1 * IEEE 488 (labelled so), real-time clock (guess so, there is an OKI MSM5832 chip, a crystal, and a 3.6V NiCd battery). Other chips: Z80ADART, Z80APIO, TMS9914A (IEEE488 controller), Z80ADMA. 2b) "MODEL 6401": 4 * RS232, female 25-pin sub-D connector, labelled "SERIAL PORT 1" through "...4", then "PARALLEL PORT 5" and "PARALLEL PORT 6". Chips: Z80APIO, 2 * Z80ASIO. 3) Qbus-like board, supposedly a CPU, handles made by DEC, board is 4 slots wide, labelled "PCS" (is that PCS CADMUS?), has Motorola MC68000L10, 4k SRAM (2*6116), 16k EPROM (2*2764), clock chip (MM58167), battery. Between the handles, there are two 40-pin 3M connectors (Berg style). The EPROMs have stickers saying MINITOR MINITOR R900.123 R900.123 E9 2.200LO E10 2.200HI Any hints? - In case you want to trade: I am still looking for a sound card for my friend's IBM PS/2 (Microchannel). I cannot buy one of those currently offered on eBay because they again won't ship outside U.S. - darn! -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com _______________________________________________ cctech mailing list cctech(a)classiccmp.org http://www.classiccmp.org/mailman/listinfo/cctech

1-800-DIGITAL

by gunther＠aurora.regenstrief.org

Hi, well, I made the call, tried to that is. Because of the bad power cable in the old BA23 enclosure. You were supposed to get a replacement when calling this number. However, as could have been expected, that number is no longer in service. The compaq number you are redirected to get's you into the world of compaq^H^H^H^H^H^HHP PC products. Not exactly where one would expect anyone to know about old promises that DEC made. I will make myself a replacement cable by cutting the old one and then just interposing wires with pigtails and a bit of electric tape around. I'll also use thicker cable. How hard can it be. -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

[CCTECH] PDP-11/60 in UK on eBay

by Antonio.Carlini＠riverstonenet.com

> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2028620247 The seller is Swan Computers. This was up for 500UKP the other week and attracted no bids. They also appear to have parted out a VAX 8650 and a PDP-11/70 too. OTOH it seems to be reasonably common practice when acquiring the Nth large machine to strip the useful bits (boards, cables, cab kits, PSUs etc.) and ditch the cabinet to save on storage costs. So maybe these boards have been out of a machine for quite a while now. Antonio

To me, this sounds like a CADMUS 68000 CPU, made in Germany. I've not had much experience of them, but I've seen a couple. They used a 68000 (or maybe 68010), on a quad-height card, in a Q-Bus backplane. It's a long time since I've seen one, but I seem to remember an over-the-top memory connection, not unlike a microVAX. I do remember that a lot of the support boards didn't have handles, and tended to sag, so that they had to have bits of folded card and BluTak inserted to stop them shorting together after a few years. The CADMUS systems I saw ran UNIX, a System III derivative, I think, and were used in the Department of Building at the Heriot-Watt University. I've just had a look to see if I still have any Cadmus docs, but I can't find any :-( -- Pete Peter Turnbull Network Manager University of York

What was that mystic Commodore 6509 computer?

by gunther＠aurora.regenstrief.org

There was this computer Commodore was going to make and then pulled out of the market. It was based on the 6509 CPU, I guess right before the 6510 / C64. I thought then as now that the case was especially nicely shaped (such beautiful round corners, reminescent of my 91 Chevy Caprice.) I still remember when all those boards came onto the surplus market in a German electronics mail order catalog. When Commodore pulled them all from the market. I actually bought one back then, because I needed a replacement SID or something like that (I don't remember.) So, now I was looking for something in my old junk box and that board fell back into my hands. I think I don't need it any more, may be there is some collector here who would appreciate that board and bring it to life? Nothice that this is not a running system. It's just a mother board and all ROMs are pulled. The 6509 is on there and I'll be darned if it wasn't still good. cheers, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

I don't know where to find them, but LED calculators in the 70's sometimes used 4 digit modules with a DIP-16 form factor. They looked like 4 bubbles on top of a lead frame. That would make them about 3/4" for four; but I'm not sure how you'd get 5 unless you could also find a 'single'. Not very helpful, I know, but perhaps a step in the right direction...

what the heck is this? Apple II Adaptive Firmware Card

by rigdonj＠cfl.rr.com

Hi, I recently picked up a card and external box for the Apple II. Both say Don Johnson Development Equipment Inc Adaptive Firmware Card and the box also says I/O Box. The box connects to the card via two short ribbon cables and has a 36 pin male Centronics style connector, two banana jack sockets, rocker switch and a LED on it. I picked this up in Topeka, does anyone know what it is? Joe

locating shorts Re: HP ScanJet ADF

by dwightk.elvey＠amd.com

>From: Joe <rigdonj(a)cfl.rr.com> > > >>Probably a shorted decoupling capacitor (if it's a 'dead short' or close >>to one). I have been known to carefully cut power traces to find out >>which section is shorted, and then home in on the problem. > > That's the way that I've traced shorts down. However since then I've bought a HP Current probe, they're supposed to be able to trace a short down the correct path. I've never had a need for it since I bought it so I dont know how well it works. Has anyone had any experience using one? Hi I've used a current probe a number of years ago and found it worked OK for trace short, when they were accessable on the surface. I've since found a method that works fine for me, using standard bench top items. You need a 4 or 5 voltmeter that has at least a 200 uV range and a current limiting power supply. What you do is to place about a 1 amp current from end to end of the curcuit that is shorted to another curcuit. Do not place the 1 amp through the short. This will generally create a 20-100 uV drop across the curcuit. Now, clip one lead of the meter on the other curcuit ( the one that this curcuit is shorted to ). With the remaining lead, trace along the curcuit with the current flowing through it. When you get to the point where the short is, the voltage will be zero. On either side, the voltage will be plus or minus, telling you which way to go. Check the meter regularly for offset by connecting both meter leads together. This will help you especially when you get close. For curcuits with branches, you may need to move where you put your end to end current to follow another branch. This method also works for power planes. Say there is a bypass cap that is shorted someplace. Place the current source on opposite corners of the board and trace until you have a line ( usually curved ) across the board that measure zero ( I usually tape a piece of string along this line ). Move the current source to the other corners. Again, find the line. Where the lines cross, you'll find the short. There are variations of this method that I've used to find multiple shorts. Dwight

No offense, Sellam, but this only seems natural to me.

Diagnosing a non-working Mac Performa 476?

by vaxzilla＠jarai.org

I've acquired a non-working Mac Performa 476. Unfortunately, I don't have any other Mac gear to help me with the diagnosis. I've the Performa 476 itself, which may or may not be working; I've got two Macintosh Color Displays (M1212) which may or may not be working, and one spare Performa 475 motherboard purchased from eBay. It was advertised as pulled from a working system--but I've no way to verify this. The seller was a reputable one, so I'm inclined to believe it's a good board. The 475 motherboard is identical to that of the 475. The difference between the two models being that the 476 shipped with a larger internal HD. When I power up the system, with monitor attached, the internal cooling fan spins up, the hard drive spins up (and sounds normal), and the machine chimes what I seem to recall as being the regular start up sound for this era of Mac. However, the display remains dark. If I power off the Mac, leaving the monitor on, the monitor makes a light static/crackle noise; it's the sort of sound I normally associate with a monitor that's lost the video input signal. I've played with the brightness and contrast controls without any success. If I switch the other monitor, the behavior is the same. If I switch >from the orginal motherboard to the one I purchased on eBay, the behavior is the same. It's possible both monitors are bad and/or both motherboards are bad. I don't have a multimeter to verify that the voltages coming out of the PS are correct. Nor do I know that the hard drive is functional--but I'd assume that nothing needs to be loaded from the HD in order to get the display to come up. I'm a bit puzzled, and wondering if anyone here with insight on these Macs and their displays can give me any additional pointers. -brian.

don't hook no RA90 to the internal power plug on the VAX6000

by gunther＠aurora.regenstrief.org

Hi, I think I haven't heard from Geoff of Oz for a while, are you still around? Came to think about Geoff because I have now blown two fuses of VAX 6000's internal 110V power hookups (the main power box has three what looks like standard 110V receptacles.) But not all of them are equal, so it seems. The one that's not reachable from the outside seems to be protected by a low-rated fuse. I suppose now that this is where the backup battery is to be hooked up an nothing else. I tried to drive an RA92 from there and it always burned the fuse when the drive spins up. I'm releaved now because initially I thought I might have destroyed the drive (some inner short because of dust and dirt.) But it's just that fuse. Too bad that I can't power the second external receptacle. It's this weird 3-phase conversion issue where you have to use the phase that connects to this internal receptacle but not both of those that connect to the two external receptacles. How did you, Geoff, hook up both of your RA9x down in your VAX6400? thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

RA90 not releasing session on port B? How can I reset the drive?

by gunther＠aurora.regenstrief.org

Hi, I cleaned up my laundry/computerroom real nice. The two VAX6450s now want to talk to each other (and not just stand side-by-side :-). I have the star coupler attached to the wall, at a nice angle under the staircase, which makes it really nice to connect the CI cables. Can't wait to do IP over CI between the two. So, I copied my Ultrix disk's / and /usr partition to another drive and having connected the second VAX6k to that other drive on SDI port "B" I could actually boot it with the generic kernel and so forth. Then I found I was missing something, so I wanted to get back to the first VAX and mount that drive again to add something to it. But fron then on every attempt to mount or write to the drive from port "A" causes the WRITE PROTECT LED to lite up quickly and then the OS comes back with an I/O error on writes and a write restricted error on mounts. I can't even do mount -r that drive. I tried shutting down, spinning down, resetting, powering off and everything I just can't get the drive responding to write requests from port A any more. What is the magic here? These drives seem to have a memory that lasts even when powered off. Once I turned off the main breaker before the drives were spun down. It does sound ugly, but they all work nicely still. And I noticed that they remembered the "R" status when I powered them on again. So, how can that memory really be cleared? thanks for your help, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Diagnosing a non-working Mac Performa 476?

by Innfogra＠aol.com

Not being an Apple person this might not be germane. I have found differences with the cables that attach the monitor to the computer. I had one cable that plugged in but did not work. It was lighter in weight and IIRC was missing a pin. I think it worked on an IIGS but not on a LCIII I was testing. I needed the heavierweight video cable with no missing pins to get the LCIII to come up. Both came up in color but needed different cables. Don't know why. As I said I am not an Apple person, although I would love a G3 or G4 to play with. Paxton Astoria, OR

the haunted VAX6000 has been exorcized!

by gunther＠aurora.regenstrief.org

Yes! It was very much like Antonio suggested, a good deal of previously strangely behaving XBIA and XBIB boards were still working fine given the proper environment. I replaced the backplanes/cages for both XMI and VAXBI. I figured if nothing else, the set I put so neatly into boxes last year would be less exposed to dust and grime over the last year, and I did remember that one of the vaxen, i.e., this particular one did behave strangely even last year. Then step by step debugging with a little bit of board reseating and everything works now. Yeah! This is my second VAX6450 going online. Did I mention that one of them is now a VAXvector 6450 (with one vector processor right now because I still don't have more than one of the little cables.) It's going to be a VAXvector 6440 V2 (BTW: how was the number of vector CPUs officially counted?) and the other will be a VAX 6460. Both of them have 512 MB memory, one has a KDM70 with an SA600 with 8 RA90s the other now has the KDB50 with one RA90 and one RA92 in the "basement" of it's cabinet. I'm about to connecting the second VAX to the star coupler. And then all I need to do is fix the HSC90 that still gives me a k.ci error with status 111 (what the heck does that mean?) Then the HSC90 will plug in the port "B" of all the RA90s and RA92 and uh yes, there are also the RA81 and RA82, which I can't wait to actually use. My basement is going to be cleaned out now. It looks nice with two VAX 6000 and an SA600 shoulder to shoulder. Ah, yes, now I have an XMI and a VAXBI backplane cage spare. I will get rid of it one way or the other. If you want either or both, let me know. They are free for the taking or shipping. I'm sure that only one of them is actually defect AND I'm sure the defect could be fixed (I'd probably go with round in the dishwasher or so.) If you need parts from one, that's fine too. To know what's on them go to my VAX 6000 anatomy page. If I don't hear by soon, I will screw off all the parts and let the bulky stuff hit the dumpster. regards -Gunther Here is the transcript of a working VAX 6450 selftesting: >>> INIT c123456789 0123456789 0123456789 01234567# F E D C B A 9 8 7 6 5 4 3 2 1 0 NODE # A A . .

It gets it's speed from having a better memory model. You don't have to program in BASIC with it. In fact, the BASIC is written in Forth that underlies the BASIC. From what I'm told, you can access the Forth. If Forth isn't your cup of tea, most all Forths have been able to access the raw assembly level without using yet another tool. The processor is based on the 8051 instruction set but it one or two clocks per instruction instead of 12 to one. Of course, it runs in the tens of megahertz. Mixed assembly and Forth often makes a good optimization of speed and memeory size. Later Dwight

it's networked! (my VAXstation)

by carlos_murillo＠epm.net.co

Yeeeeehah! I devoted maybe four hours today and yesterday to reading more about VMS, paks, UCX vs. TCPIP, DECNet plus and such stuff, and I was finally able (after a two year hiatus) to install the TCPIP product more or less correctly in my Vaxstation 4000/60. It seems to work and I could finally ftp the complete hobbyst paks to it (before I had to do each by hand). I get errors on startup about some proxy database. I think that I still have some configuration errors (especially in the DECnet plus side, but then again, I won't be using it to communicate with anything else DECnet), but the basic stuff seems to run (telnet and ftp clients and servers). Question: where can I get ssh for vax openvms 7.2? Question: can somebody tell me what are the step by step commands/dcl incantations to create a user with reasonable privileges? (I don;t want to login remotely to the system account). And, does the concept of a user home directory exist in vms? Where does one normally create user directories?
