Question about memory boards used on VAX 11/7xx

by cheri-post＠web.de

Hi all, I got 2 Memory Boards (National semiconductor) several weeks ago (each 1MB). Somerwhere on the net, someone says, that these can be used in VAX 11/7xx. Can I use these boards in my PDP 11/24, too ? I don't know yet, if 32bit boards can be used on 16bit machines and I'm afraid of putting them in and seeing some smoke when turning on the machine...

Reviving old hard drives

by nbreeden2＠comcast.net

Bob, I've seen this work with IDE drives that wouldn't spin up due to bad bearings. Freeze the drive in your freezer then spin it up while it's still frozen. This seems to free the bearings for a short time so the drive can spin up. I know of a couple people who used this technique to copy the contents off a dead drive, they required several freeze passes to get all the data as the drive tends to warm up quickly once pulled from the freezer and powered up. The speculation has been that the metal contracts when frozen and releases stuck bearings, this has always seemed an 'Odd' explanation as the bearings and races should contract at the same rate assuming similar materials. Of course this is a last resort option and your experience may vary. -Neil >Date: Wed, 29 Dec 2004 20:11:06 -0500 >From: "Bob Lafleur" <bob_lafleur(a)technologist.com> >Subject: Reviving old hard drives >To: "'General Discussion: On-Topic and Off-Topic Posts'" > <cctalk(a)classiccmp.org> >Message-ID: <DJauNjVuMhvqgStMVhE00000031@dj> >Content-Type: text/plain; charset="us-ascii" > >Is there a repository of information regarding reviving old hard drives? > >Specifically, I have a Seagate ST3390N in a Mac Iici that appeard not to >spin-up anymore.

Surface to mass differences should allow one to cool faster, and although both may in the end shrink to the same size, one should shrink quicker, and the initial shrink may be all that is popping it free. I'm not saying that is why the trick works... I'm just pointing out some validity in the plausible nature of the idea. -chris <http://www.mythtech.net>

Ordinary PC-type 72-pin SIMMs should be fine, but I think you need Fast Page Mode rather than EDO. You don't need parity, but it will do no harm if you have 36-bit SIMMs instead of 32-bit. lowendmac mentions 80ns, so 70ns or 60ns will also do. I bought 4 x 32MB SIMMs about 4 weeks ago on eBay for an SGI, which wants FPM+parity and gold contacts; it was quite cheap (under $20). The same seller had quite a lot that was non-parity, and he even mentioned Apples. -- Pete Peter Turnbull Network Manager University of York

Powermac 8100/80 RAM question

Hello all, I have a Powermac 8100/80 that needs a RAM upgrade. Lowendmac.com says that it can handle 72-pin SIMMs, up to 32MB each. My question is this: does it take the same 72-pin SIMMs as a PC, or does it require special "mac-only" SIMMs? Google only showed people still selling the RAM (for outrageous prices), and I couldn't get actual specs on the RAM itself. Thanks for any help .... BTW, the 8100 was introduce in early 1994, so I think I'm actually on topic! :-) Rich B.

Reviving old hard drives

I've talked to the engineers at DMA Systems (removeable HD mfg that was bought out by Ricoh?) and they indicated they would test run their drives with no cover (in an open room, not a clean room.) The caveat was to not be in a dusty or dirty environment. I've done what Jules mentions and it works well! I did that on a HD just to see what would happen ... nothing, and it worked fine for another couple of years after I put the cover back on. There is usually a filter inside the (older?) disk drives and I *think* it will clean out any dust that got in the drive while the cover was off. > Jules Richardson wrote: > > Another bonus last-resort trick is to pull the lid on the drive and get > the platters spinning 'by hand' - just don't touch the data surfaces, > and there's no guarantee as to how long the drive will keep going (don't > run the drive open obviously - in fact some drives won't even run up to > speed when open).

Powermac 8100/80 RAM question

by cb＠mythtech.net

>No systems that shipped used EDO. We went from FPM to SDRAM. Not entirely accurate... although the ones I was thinking of don't use EDO anyway (my memory told me the 660AV and 840AV required EDO memory installed in pairs... I just looked it up and it appears I'm wrong, they don't care). However, there ARE Macs that require EDO (according to Apple), but upon looking that up, it looks like it may only be DIMM based machines, so it still wouldn't apply to this instance (where I said there were some that required EDO 72 pin SIMMs). So you are correct, it appears that there are no 72 pin simm based units that require EDO, however, EDO is required in some Macs that use DIMMs (which as everyone knows is NOT the same thing as SDRAM). Specifically, the 4400, 5500, and 6500 require EDO... and the 7200 can NOT use EDO, in fact there is a note saying it may damage the machine. The rest can use FMP or EDO simms or dimms (according to the same chart, the 8100, the system in question, wants FMP but will use EDO as FMP if EDO are installed... which is consistant with what I have found of any other 72 pin SIMM mac I've upgraded) <http://docs.info.apple.com/article.html?artnum=19456> -chris <http://www.mythtech.net>

by cb＠mythtech.net

>Ordinary PC-type 72-pin SIMMs should be fine, but I think you need Fast >Page Mode rather than EDO. Based on my findings, I've yet to run into a Mac that can't use EDO. Some require EDO, but so far, all the ones I've played with that are supposed to use FPM, work just fine with EDO instead. (note: I have never upgraded an 8100, so for all I know, that could be the one model that really does care). Again, this is based on 72 pin SIMMs. It seems that Apple's 72 pin SIMM requirements were pretty loose compared to their other memory requirements. -chris <http://www.mythtech.net>

Google only showed people still selling the >RAM (for outrageous prices), and I couldn't get actual specs on the >RAM itself. Plain old cheap PC simms work fine. If you can, get non-parity as that was what it really called for, but I have successfully used parity in any mac I've tried (that require 72 pin simms that is... 30 pin ones will NOT work with parity for the most part... there are a few exceptions like the version of the IIci that was specifically designed TO use parity, as well as IIRC, some of the last models to use 30 pin would work with either style). You should be able to pick them up cheap from enough places. One thing in your favor... the Mac isn't very picky about matched simms, so you may be able to buy a bunch from somewhere like 18004memory.com that sells unmatched parts pretty cheap in their clearance section. -chris <http://www.mythtech.net>

DEC: System Industries 9901-6082-A

by jkunz＠unixag-kl.fh-kl.de

Hi. I have a quad Qbus board in front of me. It is labeld "System Industries 9901-6082-A". It has two 40 pin IDC connectors, lots of TTL, four AMD2905, three EPROMs, the usual PALs, ... This is some sort of disk controler according to google. What I didn't find out: Is this the complete controler or is this only a part of a controler? There is a "System Industries 9900". It is a separate 19" rack box containing a SMD (?) controler. It is interfaced to SBI or UniBus or ??? with a bus interface card and ribbon cables. Maybe the card I have is the QBus interface card? -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

Defective IBM core memory by frost.

by h.j.stegeman＠hccnet.nl

Hi, I am a happy owner of a IBM System/3. This system was standing unpacked in my garage for more then 10 years waiting to be put back into service. If was stored in perfect working condition. Last week I started to restore my old IBM system/3 to working condition. After solving several problems in the power up sequence the system was ready to be IPL-ed. Immediately I had a processor check. Checks lights indicated storage problems. After investigation I discovered that the several X wires on the core planes where open. These wires are mounted by IBM on a square frame. During a heavy forst period (I live in the Netherlands) while standing in a unheated garage the copper X wires shrink and broke. About 20% of the X wires are broken. None of the Y wires (???). These planes are stacked on top of eachother by IBM and the X/Y wire terminals are welded together. This makes the planes non-accessible to repair the open wires. I now have 2 unit (each 32k) both located in the system defective beyond repair and idem a spare unit of 16k. Any one who has such IBM storage unit available to bring my IBM S/3 back to live...? See http://home.hccnet.nl/h.j.stegeman/32kBSM.jpg Regards Henk Stegeman

It's not compatible with the VAX-11/780, nor the 11/730. However, the memory backplane is compatible with the MK11 memory box for the PDP-11/70. Unfortunately, the MK11 controller only deals with 256Kb memory boards. So if you'd like to use these 1 Mb memory boards in an 11/70, you need a small hardware hack, and a small software hack. The hardware hack is to tie four board select lines from the backplane into to address lines for the memory card, and the software hack is to reset all the ECC bits in the high 768K of each card, since the MK11 controller only clears ECC on the low 256K. I have done both of these things on an 11/70 here in the past.

In October 2001, I sent electronic mail messages to Kay, and to all the members of his original Smalltalk team whose e-mail addresses were available on the Internet, asking this question. The replies I received were unanimous: Ayn Rand¹s epistemology was not discussed by or known to any of them.

HP-41 Synthetic Programming Made Easy

I just found a nice book that I'm sure a few people (Tony in the least) would find interesting (if they don't already have a copy). It's called "HP-41 Synthetic Programming Made Easy" by Keith Jarett. It was published in 1982 by Synthetix. There's no ISBN but it does have a Library of Congress Catalog Card Number of 82-62786. It's 192 pages and seems very in-depth.

Semi-OT: Acard LVD-to-IDE Bridge

by healyzh＠aracnet.com

Has anyone played with the LVD SCSI to IDE bridges that Acard is selling now? I'm trying to figure out if they'll sync down to the speed of the SCSI bus that they're plugged into. I'm thinking about getting a SCSI-to-IDE bridge for my VMS system which currently uses UW-SCSI. If it will work, I'd just as soon buy a LVD bridge, as they're cheaper and will be better when I finally upgrade my VMS system. I'm tending to suspect they don't sync down, as they sell U-SCSI, UW-SCSI and U160 LVD SCSI models. Zane

Ethernet Cables?

This _could_ be one. Not very likely, though. I think Jim is more likely correct, that it's a console cable or at least some sort of serial cable. The colours Marvin mentioned are often used for flat cable; baluns are for twisted pairs. Also, serial cables commonly use a scheme where the innermost two wires (4,5) are ground, either side are receive and transmit (3,6), and handshake lines DTR/DSR (or DCD) (2,7) and CTS/RTS (1,8) are at the edges. By that scheme, Marvin's cable would short DTR to DSR and RTS to CTS, which makes sense. -- Pete Peter Turnbull Network Manager University of York

Couple of pdp-11 items wanted...

by mross666＠hotmail.com

Does anyone by any chance have a good 11/70 backplane that's surplus to requirements? I've a couple of QED-95 boardsets(1), but no 11/70 this side of the Atlantic to put them in... :-( (I plan to build a tabletop 'ultimate 11/70' with the QED-95, modern switcher power supply, Emulex SCSI, and internal SCSI disk... got all the bits except the backplane!) Alternatively, and even less likely, does anyone have a spare CIM-60 card? This is the QED front panel interface card that's required to use the QED-95 with an 11/35 chassis... Replies via email please, the list digests I receive are patchy at present - they arrive all in a lump every ten days or so, with nothing in between! (1) purchased on epay - latest one: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5149783592 Discussion point: this seller has had quite a few QED-95s recently, and also quite a few Setasi PEP70/Hypercache sets. The PEP70/Hypercache consistently goes for much more money than the QED-95 - up to $300-400 for a set, I've seen. Anyone care to speculate why? Thanks Mike http://www.corestore.org

Problems with my PDP 11/24 (was:Question about memory boards used on VAX 11/7xx)

Thanks for this information, Patrick. I guess, I'll have to wait for such a VAX, I haven't one yet ;-) Currently, I'm setting up my 11/24. It comes with an RL02. Yesterday, I worked on it a bit, checking grant and bus continuity, everything's fine now. I found out the bootstrap adress for the RL02 (BOOT Proms are located on the Unibus Map Module (KT24)) and gave it a try, with the RL02 disconnected. No problems with typing in digits with the VT420 terminal. This morning, the 11/24 apparently don't accepts commands from the terminal, why ? On the CPU-Board, the CLK-LED is always illuminated, even when I press the Boot-button. Then, the RUN - und the PROC-LED turns on for a moment, that's all. Yesterday, when I typed in the bootstrap adress of the diagnostics-PROM, the 1 - LED turned on. The 0 - LED always remained off. Today, no typing in is possible. When I press the boot-button, I obtain something like @000002 I need to know the meanings of the LEDs on the CPU-Board. Can anyone give me some help ? In the Maintenance-Card, the functions of the LEDs are described but it doesn't appear to be on the net somewhere... Thanks alot in advance !

Help: Looking for IBM timing belt replacement.

by h.j.stegeman＠hccnet.nl

Hi all, Who can help me with a source for a timing belt for my IBM 5203 line printer ? The old belt has given up after 13 years... See: http://home.hccnet.nl/h.j.stegeman/IBMbelt.jpg. It is a US sized belt: Tooth pitch: 0.125" (1/8)" (this pitch size makes it hard to find) Witdh belt: 0.500" (1/2)" Outer length: 13 inch (98 tooths) Thickness belt: +/- 0.080" Finding this belt in Europe is hopeless, all metrical sizes. Thanks for any reaction / tips that will make printer work again ! Regards Henk Stegeman IBM System/3 owner.

by ss＠allegro.com

Hi, I received the following from a friend in France. If anyone is interested in it, email me and I'll send you his email address. ------- Forwarded message follows ------- ... While browsing my dad's attic a few days back, I stumbled on old Vectra and MS-DOS manuals, ca. '86. There is the complete documentation set that was sent with 286-powered machines, complete with MS-DOS 3.1 documentation, plus a QuietJet user manual, and a few other items. If you are interested, I can e-mail you a complete list. The stuff is yours for the price of shipping. If you are willing to pass this on to another possibly interested person, that's OK. Otherwise, it will all go to my dad's trash can. I've asked my dad to wait a few days [before trasking the stuff]. ... 91240 SAINT-MICHEL-SUR-ORGE FRANCE ------- End of forwarded message ------- thanks, Stan

Paging Roger Merchberger

by rcini＠optonline.net

I hate to use the CCList for this and I appologize in advance, but I can't reach Roger at any of his 30below.com addresses. Every message I send regarding the CCArchive List bounces. At this point I can only lurk on that list because I can't post to it from my subscribed email address. Thanks.

Not ten years old, but...

by gordon＠gjcp.net

... has anyone had experience of repairing Belinea DH-1764 monitors? It's a rather nice 17" monitor, but it has started losing width - the image is *almost* right with the width set to full but then the pincushion correction goes a bit funny. Cleaned up and resoldered obvious dry joints which stopped the flickering. Dried up electrolytic somewhere? The original symptoms were a width-wise flickering *very* intermittently, then one day I turned it on and the picture was a couple of inches too narrow. Gordon.

Celebrity Classics Sighting

by gsutton9503＠wavecable.com

After hearing about the big earthquake and tsunamis that pounded the Far East, I found myself wondering about one of my all-time favorite sci-fi authors, Arthur C. Clarke. He lives in Sri Lanka, one of the areas that was hit hardest, so I was snooping around the Web to see if I could find any info as to whether or not he is okay. During my search, I came across this real cool pic of him working hard on 2010: Odyssey 2. The copyright date on the picture is 1984, so it is no surprise that a couple cool classics would be involved. Check it out... http://www.lsi.usp.br/~rbianchi/clarke/ACC.Kaypro.gif

Jonathan Gevaryahu lord_nightmare_(a)t_users.sf.net jgevaryahu_(a)t_hotmail.com P.S. sorry for the multi-send, comcast's mailserver seems to have some sort of a rate limit against it by whatever isp classiccmp runs behind, so the original message will probably arrive after the auction is over.

SCSI>DSSI (I owe someone a thank you)

by thompson＠new.rr.com

A few weeks ago someone (Sorry, I forgot who) pointed out a DSSI tape unit available on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5144248734 I bid on it, thinking that it would be phun to play with at a low price. I won, and the unit contains a couple of old DDS SCSI tapes but more importantly a CMD CDI-4000 SCSI/DSSI converter which appears from the SET HOST/DUP firmware to be identical to my other CDI-4000 which does either SCSI disks or tapes just fine. Woo hoo! Score. Thanks Paul

HP 5036a manuals

by mokuba＠gmail.com

If you still have the manuals for loan, I'd be more then happy to scan them in the mornings before school, I'd love to get copies of them and to do that I'd be more then willing to scan them up. Comp teacher has a scanner I can use in the mornings, so that's good! Heh, if you can, I'd love to, just laid hands on a trainer that seems fully functional, and I'm looking about for manuals, hard to come by on the 'net though ! :/

Question about memory boards used on VAX 11/7xx

by cheri-post＠web.de

Hello guys, > > Can I use these boards in my PDP 11/24, too ? > Nope, not if they're 7xx boards. If these are standard UNIBUS boards, > you should be able to use them in both the 7xx and a PDP-11. > That's the info I found on the net from a 11/750 FAQ: "National Semiconductor Memory Systems: 1Mb memory boards. These boards have PWB 551109464-002 B PWA 980109464-001 D etched on them. They have a push-button switch for disabling the board, and a spare memory chip in a socket on the board. Board has green and yellow LEDS, which should normally both be on. Disabling the board causes the yellow LED to go out, and the red LED on the L0016 to come on, indicating bad memory configuration." Fred, what do you mean with "very wide boards" exactly ? These boards do have 6 fingers (hex wide) and fit into a usual UNIBUS slot. What are the differences between the VAX11 bus and the ordinary UNIBUS ? Can I find that out with a closer look to the pins ?

S-100 Polymorphic Systems card questions

by Saquinn624＠aol.com

I have a S-100 based system that seems to mostly run, but I have some questions on the video card. It is a Polymorphic Systems card, but looks different from all the examples I could find on the internet Markings are: Polymorphic Systems (c) 1976 I.P.C VIDEO? rev 0.0, with most chips aligned vertically The keyboard? port is a 14 pin DIP socket in the upper R.H. corner, next to a 8212 I/O chip. Between this and the VIDEO marking, there are some pads with heat damage that have the symbol for Zener diode across one of them. I have no idea what the component specs are for these pads. Also, 2 questions: does anyone have the DIP switch settings table for this card? 7 switches, currently set at 1 1 1 1 0 0 0 and (2) the 8212 interface makes me think that the keyboard is some sort of parallel interface, but the computer came with a DIP header connected to 3 wires (bonus question: this card has some jumper wires and a resistor soldered on the trace side of the PCB, is this official, or is this a hack? the joints look sort of "hacky" the resistor goes between +Vcc and pin 20 of the 6571AL, the jumpers are between some of the 74XXX gates on the L.H. side of the card [where the 7805 V.R. is]) found it at my church garage sale several years ago, so I can't "ask the owner" Scott Quinn
