Some DEC drives do have a jumper to select spinup on power-up, but the RZ23/24/25 definitely don't (the original Connor drives do, but DEC changed the firmware) and some notes I have here suggest the RZ55/56 have different firmware too. What you'll get out of the drive depends on what the OS is trying to do: a SCSI MODE SENSE command will work fine, but you won't be able to do anything more interesting until the disk has spun up (which is done by issuing a START UNIT command). DEC used to have a utility called RZSPINUP to do this, but any SCSI utility that can issue a START UNIT command would do as well. -- Pete Peter Turnbull Dept. of Computer Science University of York

VAXstation 3100 history (Was ... different)

by truthanl＠oclc.org

Allison,or Anyone I recently got my MicroVAX I up and running it's MicroVMS 4.1 I listed devices and have an RD52 as DUA0. and an RX50 as DUA1 and DUA2 I did not see any directory commands to tell how much disk space is used/available. Are there any? Nor did I see any FORMAT command. (Which at this point I want to AVOID, because I don't understand the Backup process or target backup media capacity constraints. It sounds like backup clones the OS on the same drive in "renewed" and/or "rebuilt" files ) According to Allison's prior post, should I assume this RD52 is a 30MB MFM non SCSI drive? I also have a Plessy 6600/6700 system which has a 84MB-90MB drive which I think hangs on a DEC compatible SCSI controller. (I believe the Plessy is an LSI-11/34 clone.)The Plessy also has a Cipher F880 1600 bpi 9-track tape drive connected. Is there a chance I could Load the Hobby openVMS on either one, or both of these systems in a cluster? It seems to me the more capable system would be the Plessy with larger HD and Tape Unit already installed, (However I have never booted it, and I have no Idea what OS currently resides on it.) I believe someone gave an earlier response that the MicroVAX I was too small to run openVMS alone.

RZ56 Help needed

by peter＠joules0.demon.co.uk

I hope this is on topic, it can't be far off ;=) I am trying to install NetBSD on my MicroVAX 3100. I would like to install it on the RZ56 which is in its own expansion box. The problem, or so I am told, is that the drive as it is needs to be told to spin up and NetBSD doesn't do that. It has been suggested that there might be a jumper to tell it to spin up automatically. Does anyone here know if that is the case, and if so, where it is? -- Regards Pete

As a first attempt to see if it will work at all, you can do a SHOW DEV at the >>> prompt to get the console to spin up all the disks. It's been my experience that NetBSD hangs while trying to probe the SCSI bus if there's an RZ56 on the SCSI bus. I'm not aware of a jumper that makes the RZ56 spin up, but there is a setting in one of the mode pages. There was a program under Ultrix called rzdisk that allowed you to, among other things, tell the drives to spin up at power on. I think there was a similar program for Alpha/VMS as well.

RZ56 Help needed

by truthanl＠oclc.org

I know nothing of the RZ56, BUT several seagate drives had jumpers for Motor Start and Delay Motor Start. In Seagate terminology if the Motor Start jumper was connected then the Drive Waited for the SCSI "Start Unit" command to start the drive. IF the Motor Start Jumper was NOT CONNECTED the drive fell through to a delay motor start scheme. If the Delay Motor Start jumper was MISSING,-the delay was disabled. If the Delay Motor start jumper was installed the drive multiplyed the SCSI ID by 10 seconds and spun up the spindle. So ID 2 would spin up in 20 sec. ID 3 would Spin up in 30 sec. etc. I assume ID 0 would start immediately on power up. I had also seen some IBM SCSI drives that had a motor start jumper termed "start on command", otherwise they powered up immediately. But then again those were Seagate and IBM schemes, I can't speak to DEC RZ56..

Solder Melting Point

Eutectic > solder (63/37) melts at about 361 degrees F and the melting point raises as > the percentage of either the lead or tin content raises. That's not *exactly* true; the solidus point (the temperature at which it begins to melt) remains almost exactly the same, but the liquidus point rises. In between, though, the solder is rather pasty. That's great for old-fashioned plumbing, but it's apt to produce dry joints in electronics, so for practical purposes, the useful temperature rises just as Marvin says. For example, 40/60 solder has a liquidus point of 227C (440F) and 60/40 has a liquidus point of 188C (370F). Adding certain other metals, especially bismuth, lowers the melting point, though many other additives, such as antimony, raise it. According to my Multicore Solder list, the recommended bit temperature for 40/60 general-purpose electronics solder is 354C (670F), and for 60/40 it's 308C (585F). Personally, I'm never that precise; I just twist the setscrew on my Oryx TC irons until they work right! "Silver solder" comes in a variety of grades, the ones with the lowest melting points are ArgoSwift and EasyFlo2 which melt at 600-610C (1100-1130F, that's a dull red heat). EasyFlo2 is 42% silver, 17% copper, 16% zinc, and 25% cadmium. Most engineering silver solders are silver+brass based like this. A few are silver-bronze (bronze being an alloy of copper and tin). The "silver-loaded" solder Tony and others mentioned is a soft solder containing 62% tin, 36% lead, and 2% silver. It has a melting point of 179C (354F) and a recommended bit temperature of 300-310C (570-590F). Other silver/tin/lead solders like Comsol (I bet Tony has come across that) and LM5 are high-melting point soft solders, with a high lead content. I've seen them used for fusible resistors and the like. I expect this is at least four times as much as most of you ever wanted to know about that silvery-grey stuff that holds the components on... -- Pete Peter Turnbull Dept. of Computer Science University of York

And I have a saron or two to keep it company (although it turns out the saron is tuned in slendro, and the gong in pelog. Oh well.

The gong is detectably a fake [*] when you look at it, but I chose it on listening, not looking. The stand is a blatant fake - a combination of two incompatible ethnic styles - and judging by the newspaper used in construction, dates from around January 1997 (I bought the gong in July or August that year) Philip.

This is the same type no. as the 115MB used in the IBM 8580 PS/2, but with a different feature code, and the block size switch set to 512 bytes, instead of 256 bytes. I've installed the 8580 variant in the 5363, with switches on the disk set per the IBM 5363 MIM specs, but the init routine pops an SRC indicating that the defect map is missing or damaged and refuses to LLF the disk. I suspect this is due to the fact that the factory defect map was written with 256 char. blocks instead of 512 char. blocks, but I'm not sure--and I don't trust the IBM error codes since they aren't exclusive. The only variable I haven't eliminated is the drive electronics. Before I spend time swapping drive boards, I wanted to consult with other folks who are prone to commit such foolishness and see if anyone had any wisdom to share. If the drive boards don't make any difference, my next project is an attempt to hack the ROM on the 8580's ESDI controller to see if I can make it work with 512 char. blocks, then try to re-write the defect map. -- David Wollmann ICQ: 10742063

Aha! Another VAXBI survivor! The company I used to work for did a quad IEEE-488 interface and a MIL-STD-1553 interface. I did the firmware for the IEEE-488 interface (imaging a Z80 looking up user-space addresses in the page table. Fun!) and the device drivers for both interfaces. We did hardware debug by running CP/M on one of the IEEE-488 cards; that's right, I have a VAXBI machine that runs CP/M. >At least we priced the card high enough to break even >on the production costs and the cost on the 8300, barely.

The problem is that the bloody thing simply will not die; I've been averaging about one inquiry a quarter on it. Roger Ivie ivie(a)cc.usu.edu

Hey, I'd not spotted that. Yes, gamelan music is very binary: although the very slowest pulse (marked by the gong ageng) may not be a binary multiple of the next one up (gong suwukan, which is what I think I have), all the others are indeed binary subdivisions. One characteristic of gamelan music is that it tends to subdivide so far, and slow down so much, that I lose track of the tune in irama wilet or anything slower (I can't remember the names of half of these, it's so long ago) Something I never managed on either trip to Jakarta was to watch a wayang show.

When my contract ran out in April, they were still a couple of projects running on the cluster of an 8550 (now defunct and a source of parts), an 8700, an 8810 and some model of 7000. There were numerous 8650s and 88xxs and many stripped shells of 6xxxs earlier this year. As I've written before, no chance of rescue. :-( The VAXen, at least, being as big as they are and that particular data center being as lightly used as it is, they haven't bothered to clear out the machines. It's easier to leave them where they sit than to move them. Perhaps they'll clean house in the New Year. Oh... I almost forgot about the pair of RP06 drives sitting in the middle of the room with nothing to talk to. There is *nothing* anywhere in there that could *possibly* have a MASSBUS. I suppose that, given the large space _near_ the RPs that there was once a 785 or something similar but has been gone for years. > Bell Labs is pretty much Suns, PC's an occasional SGI or HP and > no visible DEC.

VMS 4.7 was VAXstation 3100 history (Was ... different)

by ndiablo＠diablonet.net

Really, in my opinion; its not _extremely_ bad just for some basic poking around in VMS (which is all I can really do with such a minimal install anyways :) I once had a 386SX-16 running like Slackware Linux 3.5 as a NAT gateway on my LAN with 4 megs of RAM... after that, pretty much anything else seems fast (considering it pretty much ran from swap :) I'd like to get some more RAM for it.. originally, it had a 6 meg expansion board, but it turned out to be bad so I removed it.. I'd like to get the system expanded to something a bit more usable, but i've not had much luck tracking down memory (and I gather the stuff that is out there usually is a bit expensive). On the other hand, I'm looking into getting a VAXstation 4000/VLC with 24 meg, which should be a little bit more useful for general VMS exploration.. then I could set aside the 3100 more for preservation and "waiting for parts". -Sean Caron (root(a)diablonet.net)

<Hmmmm... Can anyone distribute a version of VMS? I have a few TK50s <with VMS 5.x on them, but I don't want to sell them (or loan them <for fear of damage.) You can copy or give them away under the hobby license program.

Basically DEC copyrighted the programs on the media and still claims ownership but allows use for noncommercial use, under that case Copying it for the same use is resonable. I'm sure there are some fine points on this I'm missing. <If I set up a private website, and placed images of the TK50s suitable <for generating new TK50s from, would Compaq come after me?

I think the official max for the 11/725 might have been 3 or 4Mb, possibly due to cooling restrictions - it was the same power supply as the 11/730-Z, so it wasn't power, per se.

I never saw a third-party board over 1Mb for the 11/730, not that there weren't such beasts. My employer would have bought one if it were under $500/Mb. We did have some EMC 1Mb boards that used 256x1 DRAMs - same board size as a DEC 1Mb board, of course, but 90% empty. I threw them into the 11/730 as we found them because they obviously used less power and generated less heat. Good, solid boards. Never had one fail (can't say the same for the DEC boards, but we did have every machine maxxed out providing more statistical chances for failures). -ethan ===== Infinet has been sold.

<Wow.... I HAD planned on putting hobbyist 7.2 on my recently acquired <3100/m76, 16Mb, RZ23(wiped). Guess I should set my sights on a bigger driv <or older OS.

The install really wants (full boat) a RZ56 (667mb) for comfort but there is easily 250mb free after your done so you can see it works. If you want to live only with a RZ23 then early V5 such as 5.4 or 5.5 is a good choice if you don't install DECwindows or the optional libraries. I've jammed 5.4 into a RD53(71mb) with 11,000 free blocks when done! Allison

Yeah, probably for the long term, but if you want something to play around with _right now_ its not bad in terms of responsiveness and very basic usability.... I pretty much crammed the whole base OpenVMS 7.2 VAX system on there (sans DECnet) and still have about 8 megs to spare :) Personally, I was rather surprised that OpenVMS would fit (usably, albeit not much) on such a small drive in the first place :) -Sean Caron (root(a)diablonet.net)

HP Apollo Series 400

by ndiablo＠diablonet.net

Wow, _very cool_ in my opinion :) Those are old HP/Apollo workstations. They run either HP-UX or Domain/OS UNIX. The Series 400 was the last 680x0 based series of workstations that were produced by Apollo shortly after they were purchased by Hewlett Packard. Definently interesting systems; especially if you got one running Domain... I believe you can run NetBSD on _some_ 400 series systems (perhaps just the 425t; I have not checked in a while) if you're looking for something a bit more current. They do need fixed frequency monitors to run; and I think the keyboard/mouse on them are HP-HIL (although there may be a second alternative interface also; i've never actually seen one; just read about them :) In any case, if you don't want one of them, and are willing to ship it, i'd pay a few bucks for one :) -Sean Caron (root(a)diablonet.net)

The most basic VMS kit (that is, without help pages, without libraries, certainly no DECWindows!) for VMS 6.1 won't fit in the 25 Mbytes available in a RC25. 6.2 "officially" requires more than 120 Mbytes for a basic installation, but if you fool its installation procedure you can shoehorn it onto a RZ23 (100 Mbytes) >I suspect it was a question of RAM. Looking at the configurations for the >11/725 and 11/730 it looks as if the 11/730 would hold at least a couple >more MB. Officially the 730 only holds 5 Mbytes. I don't know if there's any way of extending this. Remember also that the RC25, if the "fixed" platter is used as a system disk, can be spun down to change the removable data platter. The host OS needs to be aware that its system disk might be spun down, and it has to be patient enough to wait for it to come back up. The PDP-11 OS's know how to do this, and the last version of VMS to officially support the 725 with RC25 knows how to do this, but I don't know if they included support for this in the more modern versions of VMS. My 11/730, when I had it, ran VMS 4.6. >I'm wondering if it wouldn't be possible to replace the RC25 with a 3rd >Party SCSI controller. Though I'm not aware of any 11/725's in anyones >collection. I know of a 11/725 still running a monitoring/logging application at a nuclear power plant, booting from a RC25 under VMS 4.2.

HP Apollo Series 400

by philclayton＠mindspring.com

Today I found several HP Apollo Series 400 Computers headed for the dumpster. These were used as I think some sort of Servers for a medical facility. There were 20 or 30 of them I only took 5.. Opened them up and they each have a SCSI hard drive and I think 32MB RAM, However they have no Floppy drive, ISA or PCI slots in them.. They support 3 serial ports, Parallel Port, SCSI Port, Kybd, Standard Network Interfaces, and Audio In and Audio Out.. They have a place for a second SCSI drive also in them. The Processor looks to be a Motorola 68040 I think.. I hooked up my VGA monitor and powered up , but it appears to be out of sync, or a non-standard VGA out put. I could see part of a color screen, but the screen seemed out of sync and not really readable. Does anyone know what these are ?, And other than parts are they worth anything.? Can I do anything usefull with them.. ? Thanks, Phil

What did Ampex make that used core memory?

by rigdonj＠intellistar.net

I picked up a core memory board today that was made by Ampex's Memory Products Division. The date code is 8010 and the ICs are dated 1979 so it was probably made in early 1980. The sticker on the board sasy that it's a 32K x 18 memory. The board is BIG, 11 x 14 inches and has assemble number 3293212-01. Does anyone have an idea of what it's for? Joe

by dylanb＠sympatico.ca

I was given the name of a company a couple of days ago through the company I am getting my Super Computers from. They told me to give this guy a call and see if he had anything I was looking for. I called the number and asked to speak with an officer of the company.. the answering service took my name and number. About an hour later the owner of *this* company called me back and asked me how he could help me. I told him I was looking for old minicomputers, not some flake.. paid for shipping and paid more than scrap prices... I asked him if he ever got minicomputers/mainframes in. (getting interested) He laughed at me and said his crew of *20* goes through and cuts up for gold more than 15 MILLION pounds of mainframes per year. (I thought he was full of shit). I told him my scrapping company name and he invited me out. I flew to his place and this is what I saw: When I got there I saw a huge building with an office. In the back of the building there were 4+ forklifts driving around like mad with skid fulls of IBM mainframes and dropping then op top of each other. When I pulled around and parked my rental car I saw a guy with a pair of shears inside an IBM 1130 :-( chopping it to pieces. I went inside this *factory* and 40 feet high in places were stacked super computers, minis, micros (apples, PS/2, micro vaxes, etc), and an unbelievable number of boards. After touring through the work area I found the office and talked with the owner (was rather busy).. He gave me a quick tour showing me some super computers they were hacking up, HDS (Hitachi data Systems), IBM 3840?, and some other water cooled high speed CPUs. It blew me away.. I never thought there was such a large gold processing site for this.. that's all this company does. They also melt down CPUs direct from IBM , Hitachi, etc... I missed a bunch of old DEC stuff by one day.. They guys were just finishing killing a bunch of PDP-8s and 11s. (here is the positive spin): Of course being in total shock (I never saw so many apple computers piled to the ceiling waiting to be stripped)... we talked price on some of the systems. I can't buy them from him at scrap prices *nor* will he put systems aside... I asked him if I could go through the warehouse and check for some parts (promised not to be a nuisance).. I found a heap of super computer boards and brought one to him [the other stuff I wanted had been butchered.].. he did not want to sell them at first as he was *required* to destroy them. We came up with a deal: Any mini/mainframe computer with front panel switches and light will be put aside for one week. I have to fly down every week to see what he has there (quickly) and purchase immediately what I want. As my references panned out he will allow me to purchase boards and equipment from him under three conditions: All serial numbers removed. I don't publicize what he is doing to historical computers. [don't know why he cared] I *agree* to destroy anything I buy from him ;-) **** His company generally pays $8-10K for a super computer as the raw materials when extracted are generally worth 4X that! [I did *not* know that.].. I spent more time with him and he showed me the insides of some of the huge IBM mainframes...[water cooled].. can't say I ever saw one before... He *only* new the metal content in every piece and $$$ .... HAHAHA (rather funny... no idea of the technology) We also cut a *really* sweet deal. He owns a transport truck line and his trucks pass through Toronto *empty* every couple of weeks.. he agreed to pick up any systems I wanted around the country, drop off the ones I wanted and he would pay me for the systems I would not want [every load must of course have a mainframe or mini for him). I bought some super computer boards at slightly above gold prices... [you will see them on EBay].. They are *amazing*. Processors beyond belief... I will update everyone with a list of the minis I get and will keep my eyes out for the systems in the wish lists I have received so far. Never in the world did I ever expect to see a few thousand minis, mainframes and micros being scrapped by so many people.... BTW: That stuff in his warehouse came in over the past two weeks *and* while I was there, there were 3 transport trucks waiting in line to dump off loads of water cooled IBM/Hitachi mainframes. On a sad note, on the way out I saw a front panel with all kind of lights and switches.. It was 8 bit and was made of plastic... It was called "data systems" or something like that.. anyway.. it was crushed. :-( I will try and take some pictures the next time I am there.. I know I am not supposed to do that but I think I can get a few snapshots of what is in there just by taking a couple of photos from the outside. I took a list of IBM numbers of what was in there and will post them later on tonight. In amazement and kind of annoyed, john PDP-8 and other rare mini computers http://www.pdp8.com

SC/MP

Hallo, While looking for info on the SC/MP developing system from National i stumbled on this message from Alisson J Parent.: On May 30, 12:24, Allison J Parent wrote: > Subject: Re: National SC/MP data > <Hi all, > <Today I bought a SC/MP wirewrapped board.

The actual part No. is > <ISP-8A/500D Some time ago i found one of these systems. It also included the original datasheets from National. It says that the voltage on pin 40 must be -7Volt. When you need more info i can send you a scan of the datasheets. Unfortunately my system doesn't function. So i'm looking for the scematics. Maybe you can help me out?
