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.

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 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

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

q about PDP11/34 schematics (clock generation)

by bert＠brothom.nl

Hi all, Can anyone explain to me how the clock generation of the PDP11/34 works? I see in the schematics on page 1-5 that clock signals are "generated" (?) by a delay line. That is: the component is referenced as E104 and the parts list mentions it as "delay line 150nS" As I don't have any other info on this part, I'd like to find out how this component works. Appearantly there are multiple signals coming from this device. Please forgive me my ignorance, I think I might be to young to know (30). TIA Bert

XXDP inventory (warning: long list)

by GOOI＠oce.nl

> I will scan the following three first as they describe XXDP *itself* : > > - AC-F053B-MC CXQUAB0 DECX11 USER'S MANUAL > - AC-F055C-MC CXQUBC0 DEC/X11 CROSS-REFERENCE MANUAL > > both of these are already on line at > www.bitsavers.org/pdf/dec/pdp11/XXDP Thanks Al, 3 less to scan :~) A question about the naming scheme of the files. As example, let's take this one: AC-E246B-MC CZRLEB0 RL01/RLV11 PERF EXERCISER According to bitsavers that would become something like this: AC-E246B-MC-RL01-RLV11PERF.pdf where the last part gives a brief indication what the xxdp is used for. I wonder if the "AC-E<number>-MC" is useful, but I have no experience in this field, so that part could be very useful but I don't know that. Also, I have a few 'patch' sheets, and their name start with "AF". That would mean that they would not remain together with the original xxdp in a alphabetic list. Furthermore, is the xxdp name (CZRLEB0) not more meaningfull? In that case the file name would become: CZRLEB0-RL01-RLV11-PERF.pdf I'd appreciate any good advice before I start next week. If you can give me (private of course) a URL, I will upload them as I scanned each one of them as .pdf - IF you can use them on bitsavers. - Henk, PA8PDP.

Back to computing topic ... Re: OT: timing belts

by dave04a＠dunfield.com

>- What is the largest computer you've fit into a car? Complete Nova 1200 system (full rack) in an early 80's Honda Civic - basically, the top of the rack (with a 9-track drive) wedged in far enough so that it didn't fall out (good thing it has a strong roof) - the rest stuck out the back and weighed the car down to bottom out on its springs - The front end felt *VERY* light, and it would feel as if the front wheels came up if you accelerated while going over a bump. Fortunately I didn't have to move it far... (Wish I had taken a picture!)

Interesting "Rare" APPLE PCI Board on Ebay

by cb＠mythtech.net

>Don't know anything about this, but thought you guys might be interested. >It has a Buy It Now of $15.... I'm not sure how "rare" it really is. One of the major mac "parts" dealers (I forget who, small dog maybe), had a bunch of these for sale not too long ago at $5.00 each. They didn't seem to indicate any limit on the supply. Also, from what I understand, the board isn't too useful as the Mac OS doesn't recognize it, and so won't work with the ports on it. It is probably about a rare as the Apple Set Top Box, it certainly seems to be as functional. :-) -chris <http://www.mythtech.net>

Merry X-mas to everyone; Token Ring Christmas gift

by Arno_1983＠gmx.de

The subject says it all... I'd like to wish everybody in "the hobby" a merry Christmas and, as I won't be online too often until 09.01.05, quite possibly a happy new year as well. Thanks to all who - both regularly or sporadically - populate this list and, friendly and helpful, contribute to the massive amount of knowledge as well as to the unique atmosphere here. Double thanks to the people who maintain the list server, moderate postings and generally "do the work", thus allowing this community to flourish. Last but not least, thanks also to everyone who helped me with the questions and tasks I was personally involved with - the network gear transport, the HP disk drive documentation and everything else I forget right now. Also, somebody has a Christmas Gift for a true Token Ring enthusiast (might even suffice for more of them); I hope he doesn't mind me sending it here - he didn't react to private mail suggesting he might crosspost it here: > From: Porkchop <porkchop(a)nic.com> > Subject: [rescue] For Rescue: Token Ring! > To: rescue(a)sunhelp.org > > My employer moved from Token Ring to Ethernet a few years ago. > Finally, the rooms used to store the old 3,000+ port network will be > needed for something else. > > Its all IBM. We have bridges, 8270s (managed token ring switches), > CAUs (controlled hubs), LAMs (expansion options for the CAUs...25 > extra ports per LAM), a few MAUs (uncontrolled hubs)... the CAUs have > fiber options, the 8270s I think have [fiber] ATM cards and some have > fiber token ring cards.

If this load is aquired, I might well be interested in some of this stuff; I've got some Token Ring NICs at home and a few more inbound, but neither cabling nor a MAU/CAU yet.

HP9845 printer timing belt

by ard＠p850ug1.demon.co.uk

This talk of timing belts has prompted me to post about the one in the HP9845 internal thermal printer (one of those machines is in many bits on my bench at the moment...), Fortunately I am not looking for a replacement belt -- I say 'fortunately' because I've enver seen anything like it. There are 3 sporckets. One on the stepper motor spindle at the back. One on the platten spindle. One on the feed roller spindle. The first 2 are conventioally driven by teeth on the inside of the belt. The last goes against the outside of the belt and engages with teeth there (of the same pitch as the intenral ones). Of course that means it turns the opposite way. I've never seen a betl with external teeth in anything else (although I have seen a chain drive with sprockets engaging on both sides). I think I mentioned that the printhead in this printer can be taken apart. It consists of a coonventioal PCB to link to the cable harness, 7 ceramic hybrid circuits that contain the printhead drivers (and serial-parallel shift registers), the printhead hybrid iteslf and a load of zebra-strip like connectors to link everything together... -tony

Old Unibus PDP-11 XXDP diagnostics

by wacarder＠usit.net

Does anyone have any info/documentation on the XXDP diagnostics for older PDP-11 systems and peripherals? I'm looking in particular for the 11/40 (11/35), RK05, DZ11, RL02, MM11 core memory, RX01, RL01 diagnostics. I have found some info on Henk's site, but would like to know if anyone has a comprehensive list and hints on how to run these, what the output means, how to answer the prompts, etc. I have created RL02 packs with XXDP 2.5 and XXDP 2.2 and I can boot and run stuff from these packs. It appears that the 11/40 diagnostics are on XXDP 2.2, but not on XXDP 2.5. I have an old 1976 DEC field rep troubleshooting guide that refers to various MAINDECs, which seem to have been the diagnostics prior to XXDP. Is there a list somewhere showing what the XXDP equivalents of the old MAINDECs are? Any help would be appreciated. I want to exercise my 11/40 and attached peripherals and see if any subtle gremlins are lurking anywhere within. Everything appears to be working perfectly with the exception of one of my three RK05 drives that I knew was problematic. Ashley

Auction Finds

by tponsford＠theriver.com

A couple of good auction finds at the U of A. tuesday: A DECWriter Correspondent which is a somewhat portable printer/terminal. This one was the model B which doesn't have the acoustic coupler, but has the internal modem and a 9600 baud EIA port. What was great about this find is that it came with the origianl Digital brown canvas traveling case and all the documentation (Operator's manual, reference cards and Programmer's manual) plus a spare ribbon cartridge. It is really, REALLY, clean. with absolutely no wear on the keypads and NO discoloration of the plastic, which make me believe it wasn't used recently, or at all! I was amazed about the ink ribbon, when I did run the print test the text was nice and crisp. Remember this is SE arizona where it is drier than a celebrity at the Sierra Tucson detox clinic. This is a circa 1982 machine too! The other find was a Heathkit H-19 terminal which I promptly sold to another fellow collector. The last was a 10 year old, big, Emerson UPS, model AP115 (1.5 KVA, 1050 watt). It unfortunatly, did not have the batteries, but was in working condition and for $2.50, I couldn't resist. I think it has a 96 volt capcity and looks like it can hold quitea few of the small 12 volt VRLA batteries. It had two heavy duty cables exiting the bottom of the case which leads me to believe it might have had an external battery case. I'm trying to find some documentation, any help would be appreciated. Cheers Tom -- --- Please do not read this sig. If you have read this far, please unread back to the beginning.

Stuff for sale, cheap

by pds3＠ix.netcom.com

I could use some RL02 packs. Could pay, say $5 each? How many do you have. Thank you, Shannon Hoskins -----Original Message----- From: William Donzelli <aw288(a)osfn.org> Sent: Dec 15, 2004 12:56 PM To: cctalk(a)classiccmp.org Subject: Stuff for sale, cheap I picked up the pile of DECstuff located in White Plains, NY the other night, and most I really don't want. I am keeping the rack, PDP-11/23, RL02s and some packs, and maybe a VT100, but the rest I don't need. So here it goes, cheap: (many) RL02 disk packs (some I think have MUMPS stuff) (2 or 3) LA50 printers (little desktop things) (2 or 3) VT100oid keyboards (may have missing keycaps) Make silly offers for this stuff - just give me something for my time and gas fetching the stuff. Shipping is from 10512. Come to think of it, someone local could probably easily talk me out of the whole pile. I must say it is not too pretty. Unrelated, I also have an ancient video game - one of those analog/digital hybrids (ping/squash/practice/soccer - the ultra cheesy games from the mid 1970s). It is a Bentley Compuvision. The paddles are included, but one is missing the knob (the pot shaft is still there). I was told it still works, but did not try it out. Also accepting silly offers for the thing.). Oh, and I also see I have a tube of Altera EP610SC-15 EPLD chips. These are surface mount - I assume unblown, but can't be sure. 17 chips is all. Same deal. Please reply off list.

Id'ing disk cartridges

by rigdonj＠cfl.rr.com

Anybody have any suggestions aout how to identify what drive/system these are for? I picked up several 15" removeable disk cartridges earlier this week but I don't know what drive or system they're for. It looks like they came from a GenRad test station so it was probably some kind of DEC based system. A couple of the disks say "Scopus Corporation System 90". Anybody have any idea what that is? One disk was made by Magntic Data and is a model 46. Another was made by Nashua and it's model 4416-16. I just found another marking that says one of the disk is for a GenRad 1796 ssytem. Anybody know anything aboutt the Genrad test stations? I think I have all of the system disks for that system. FWIW the system was used for testing a transponder for the MilStar satellite. Joe

Help: Looking for IBM timing belt replacement.

by dwight.elvey＠amd.com

Hi Grainger claims to be a whole saler. They like to always deal with companies. Even though not incorporated, they have no problem selling to our small water system company ( 7 homes ) but won't sell to me as an individual. If it is taxable, they don't need a tax number. I'd suspect that if you gave them most any fictitious name they would sell to you without question, even in small amounts.

CBBS version 3.5, and other musty stuff

by tomj＠wps.com

OK! I finally used 2, 3 brain cells, worked out the problem with my Centrol Data 64K RAM and got my CP/M machine working fine. (ANother SRAM dies in the Seattle 16K card... a bad sign). Ran a half day's worth of mem tests (good ones) seems OK. Took the bad bearing out of the noisy B: drive (it was a sealed ball bearing ass'y, not a plain like I thought; I washed it out, added some light lube, wrote down the part number, will order one, it's quieter in the mean time). Got the serial port working (simply plugged into the "PC" serial card (PCMCIA) in my linux laptop), default 9600 baud worked as-is! Using minicom on linux. XMODEM protocol failed; not sure what the problem is. Possibly minicom's XMODEM doesn't do checksum xmodem, only crc, my program (telink) doesn't do crc. So I did everything as ASCII. I converted a few diskettes worth, most notably CBBS 3.5, 1980 version. I had a read error on MODEM 2.17' diskette, but a head clean might solve it (the head goops up every 30 minutes... not a good sign). This was just a half-assed first-pass at the job. I really should simply plug the drive into linux and copy them, I'll probably do that, but I want to shake down the system too. http://wps.com/CPM-80/ Just a raw dir for now, it'll grow into a real web page.

I have a stack about the same size, and I've been thinking about scanning stuff like that (to PDFs or 600dpi TIFF), when my department gets its big scanner, probably in January (Sorry, Henk, it's not an Oce). A list of what's available would be good. I suspect that a lot of what I have overlaps with Henk's, but if I can fill in any gaps, I'll try to do so. Some of the diags are quite long, tens of sheets 2-up, double-sided, except for the first few pages, as Henk says, but some are relatively small. > I could start making a list of what's in the box. Xmas is coming :~) A list of what's available would be good. I suspect that a lot of what I have overlaps with Henk's, but if I can fill in any gaps, I'll try to do so.

Captain Magneto

by cb＠mythtech.net

Anyone here ever played the old Mac game Captain Magneto? Anyone ever win? HOW?!?! I can get the jet pack and I can fly into the castle past the killer spider, but I can't figure out how to put together the rocket. I also can't find the key to open the door on the micro island to get the laser gun. Without the gun, it is next to impossible to kill that bastard spider guarding the castle. If I can't kill him reliably, then I don't think I have a shot at getting the rocket working. I've wanted to beat this game for eons... and every Xmas I think about it as I plan to return to my folks house and memories of sitting playing for hours on end at the 128k Mac come flooding back. So its that time of year again, and I still want to win the damn game! -chris <http://www.mythtech.net>

If you require more storage, go and get a HSD05 and a Storageworks shelf to put it in. eBah has them quite regularly. A Storageworks shelf is a rackmountable SCSI drawer system, holds 8 modules. At least one of those would be a PSU, the rest can be disks or tapes. A HSD05 is a DSSI <-> SCSI converter that appears on the DSSI bus as an attached server with multiple RF7x disks. I run two DSSI VAXen off one DSSI bus sharing a HSD05. Easiest and cheapest way to get NetBSD on a 4000/200 is a KFQSA QBus DSSI card and a HSD05 :) > I've poked around in it, and on the net enough to see what all is in > it..

parallel keyboards

by dwight.elvey＠amd.com

Hi It seems that every now and then, people need a parallel keyboard. There is an auction on ebay for two keyboards that were designed for a Franklin Ace. I've bought from this fellow in the past and these are good quality keyboards. They are NOS. They require only +5V and are ASCII true out. I have hacked the PROM for this board and can give you the locations to change the key behavior for specific operation that one might need for another machine. They can take a standard 2716 but have some type of 2508 on them. They have a 8035 or 8048 as the processor. If no one else bids on these by tomorrow some time, I'll bid on them. It would be better to see these go to someone that needs them now then to sit in my spares pile. Check ebay #5149974404 Later Dwight

4Kx1 static RAMs...

by tomj＠wps.com

My old machine is slowly becoming sensible. Turns out I had three bad RAM chips in my Seattle 16K boards. They're TI 9044's, I assume are 2147 type. Jameco sells them for $6 each; is there a better source? (They're also 55nS claimed, about 3X faster than what's in there now!) I juggled chips such that the duds are at 9000 - 9fff, so I can boot CP/M (62K system) and run some programs (memtest, sid...). I've got to figure out why the floppy controller won't talk to side 2 (sectors 27 - 52) and I can do that in 16K easily. My B: drive is loud OH MAN IS IT SO LOUD I have to power it off after a program load! Need to find another double sided drive. Out of sheer laziness, to avoid even the faint effort it took to find the bad chips, I yanked all my nice static RAM and swapped in my other RAM cards, one by one: * Central Data 64K * MSC 64K * mumble brand, some acronym, no manual (I'm not at home right now) My EPROM monitor resides at 7800 - 7fff, uses a dozen bytes RAM below 7800. It self-copies into RAM and turns itself off (for a clean address space after boot). Central Data: set the jumpers right, plugged it in, Nothing Happens. (Boring story & expletives deleted) it shorted +16V, popped the fuse. Another one of those !@#$%W^% tantalums; 47uF/35V. Replaced with an electrolytic (it was just down near the card edge). Card works now, but flake-ey results, failed address-contention tests, couldn't boot CP/M. It's all 4116's, lots of jumpers for buss timing, ugh. Needs Work. Reference separate rant on capacitors. MSC: Dislike this thing's RC filters on the data/address lines! Crock-detect! I forget the problem, but had problems with one bank (32K). Mumble: Inert. All the static cards back in, debugged the problem. For the S-100 buss, I'll stick with static memory, thank you!

Another iPDS query

by Innfogra＠aol.com

Joe; Do you have any software that drives or uses the iSBX 251 bubble memory module board? My 1986 Intel Development systems handbook says "The iPDS can be used as a general purpose desktop computer. The widely used CP/M microcomputer operating system is available for the iPDS from Intel. It supports iPDS systems with single or multiple disk drives, and iPDS systems using bubble memory for mass storage." Is this inherent in CP/M from Intel? Has anyone tried this? I think I have Intel CP/M for the iPDS but don't have any bubble memory left. Nor do I have any of the 4 way iSBX boards for the iPDSs left. Paxton Astoria, OR

HP 7908/7912 head locking

And all that quick! This will no doubt enable me to prepare the drives for moving. I've pulled this and the corresponding Service Manual down. The machine wasn't run in the last few years according to the owner, so a dummy-loaded PSU checkout seems to be in order. As an HP 1000 neophyte, what other corners do I have to pay special attention to? (The Site Environmental Requirements for Disc/Tape Drives say something about an absolute filter that may have to be changed sometimes, but since the 7912 is said to use a sealed drive assy. in the Service manual, I suppose this applies to another series?) Another time this list proves to be a magnificient resouce to me... Yours sincerely -- Arno Kletzander Stud.

The iPDS is alive!

by river＠zip.com.au

Hi, Thanks to Dave, who sent me the Teledisk images of CP/M and ISIS, I was able to get my old iPDS running after sitting (and doing nothing) for the past few years. For those interested, I used Teledisk Version 2.11 running on an IBM PS/1 (25Mhz 486) running DOS5. I used 360K DD diskettes in the 5inch (1.2M capable) drive and it worked without any errors. I made a couple of copies and they all booted flawlessly in the iPDS. Wonderful stuff! The iPDS also came with a programming module for the 8748, 8749 and 8751. I'm not real familiar with these chips, but I may have a few around and I think I've got the spec sheets on them, so I'll have a bit of a play I can do with it. The MDS225 restoration is going well. I have contacted the seller who has a box of cables and I'm going to see him later this week to see if the dble density drive array cable is there. I hope so 'cos it saves me having to make one. seeyuzz river
