Message for Joe Heck - re. 7 Track tape drives

by aek＠spies.com

Look, I hate Big Oil as much as the next guy (probably more so), but there's no reason to turn down good money. -- Yes there is. There are archivists who work FOR the collecting community (not just me) that can't find legacy tape drives to read historically significant tapes. Every drive that goes into "data recovery" black holes will never see one second of use to help us. You've struck a raw nerve with this.. I've spent years rediscovering data recovery techniques that have been known for twenty years because no one in the business will talk about it. Take a look on the web for things related to data recovery, file and sector formats, etc. and you won't find squat except for the stuff individuals have reverse engineered. --

cpt8520

by gfdudley＠bellsouth.net

Hello Witchy, I sold these things for Dick Eichorn....in Washington DC against burroughs/redacdon......did quite well with sales as a matter of fact......but that was yesterday> no it isn't a home computer by any stretch of the word.....it is a very powerful, 2nd generation 8000 CPT..what is the serial Number???should be on the inspection plate on the back or near that area...when the unit came on the Market..CPT was in the early stages of financial difficulties....that did not keep those in DC from selling the box.....If you plug the 8000 key board into the 8520 you will either get the 8520 to work or not.....it just happens that way....when we rec'vd the 8520's the tech had to try to build a complete unit from what ever parts they had in house....oh the units came in complete, they just were rushed thru production. and the end result were always marginal....the original power up.....always asked for the floppy......in my files somewhere, Knoxville, tn....where I now reside/retired ....I'll try to connect/email with one other person that is still in the DC area.....we will see what activity this produces.....what prompted my search on this is a statement from a financial organization about 120 shares of stock/in stock ownership plans that split @ 60 back when I was selling the boxes....go figure......it has been a long time but the america social security system must actually keep records of that sort of thing....I left CPT Corp for Hol Inns, spent 13 years with them....Moved into the hospitality Industry...Room safes,,,,like the EL Safe ASSa Abloy...web site www.elsafe.com or www.assaabloy.com I now do contract work for www.perma-vault.com of Warminster, PA. I,m still in the hospitality industry....work is now concentrated on the distributors....they buy more.........I"ll keep a watch for your response....it should be interesting.....Happy Holidays....

Still, I'm skeptable that it's > possible to work well, and I'm fairly certain it can't be reliable. Having now read the docs, I'm partway to believing it. For those who've not downloaded the trial copy and read the docs, the trick is to have the disk to be read in one drive, and a standard disk in another. Start both drives, start reading the standard disk, but using the "Read Track" (diagnostic) command, watch for the DMA to start working (which means it's read a header and has started to transfer the data stream), and then switch drives and double the data rate setting. The idea is that by doing this, the FDC sees a valid header and starts transferring bits, then by doubling the data rate you get the raw data + clocks off the other disk. Then it's a matter of decoding what you have in your buffer; finding the sync patterns, working out the density and sector sizes, numbers and so on. I know that can be done, because I've a program (written about ten years ago) that does it. It uses a 1770 to read raw data (only from FM/MFM disks though) and then decodes it; it's designed to copy protected disks and I've never once known it fail, though it sometimes takes a while to work out exactly what it has in the buffer and how to write it back. Of course the patterns on Apple and Commodore disk aren't the same, but in principle it should be doable. -- Pete Peter Turnbull Network Manager University of York

Thank you all for the replys.... Just discovered a software that claims to read Apple II disks (and other formats too) using a normal PC without no extra hardware (except for with 2 disk drives, 1 must be 5,25)!!! . Have not tested it yet, since I didn't found my old drives.... There's the link.... it's really interestint !!! http://www.oldskool.org/disk2fdi/index_html To Grumpy Ol' Fred: ------------------- > -Apple Turnover card; Out of business, never worked very well. SOMEWHERE, I have several crates of DEAD ones. Don't you want to sell 2 or 3 pieces of those deads cards ??? > Quadlink were entire Apple][ clones on a PC ISA card. Do they have software for file transfer? (NOTE: on a sample size of ~50, we had >75% DOA rate on the Quadlink.'We received several that had connectors misinstalled, that could not have ever been tested. We had a comparable DOA rate on the replacement units, indicating that they never did ANY QA.) I'm interested in the Quadlink card too, if you still have any of them....

some RM03 questions

by quapla＠xs4all.nl

Hi All, I finally got to the RM03 I collected over a year ago from Italy. I did some cleaning of the main unit, and I have a spare absolute airfilter which I want to replace with the old one, which brings me to the first question..., how do I replace it? Apparently, the whole drive and actuator allembly can be lifted, but I can't find a lever or bolt to release in order to lift it. Q2 : is the drive a 'real' SMD drive, or a modified one? there are 2 flatcables running from the back, one wide, and one small. The reason I'm asking this is that I have heard that CDC made the drives and they did make those (model 99xx?) as SMD one's as well. Last question : in the drive is a pack, but I don't have an empty cover with a handle to place over it in order to remove it. I do hawever have 4 packs which are having their covers, and was thinking of using one of those. problem is, how to release it from the handle? Any info is appriciated :) Ed --

some RM03 questions

by aek＠spies.com

here is the specific quote: www.bitsavers.org/pdf/dec/disc/RM05_Handbook.pdf pages 2-43 and 2-44 " CDC does not recommend head or media cleaning on the 9766. <- same heads as RM03/9762 The tolerances involved are much more critital than the RP06 or similar drives. Due to the 'Burnished media' technology used on these packs, the normal pack cleaning procedures tend to leave a residue on the platter surfaces. The media requires a special power wash cycle to insure that all the residue is removed. Again, only a keen eye trained to recognize a media defect can spot a problem inspecting a pack. CDC recommends a program of media inspection at certain intervals but will not recommend any cleaning. Therefore a clean environment and proper storage of media to prevent pack contamination is strongly suggested. "

Processor Tech PTDOS 1.5 manual now online

by frustum＠pacbell.net

I've been wrestling with my PC for the past few weeks, but it is finally stable enough that I have had time to post the Processor Technology PTDOS 1.5 User's guide on my web site. PTDOS was contemporaneous with CP/M, but it was a lot more sophisticated in some ways. But don't believe me, just read it for yourself. http://www.thebattles.net/sol20/soldocu.html (the PTDOS manual is near the end, broken up into the core OS chapters in one PDF, and another PDF containing a chapter for each of the various bundled applications).

hp 21mx E on ebay (question/comment)

by jwest＠classiccmp.org

I looked a while ago at the HP 21MX E series on ebay. Just now happened to come across it again at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2772816038&category=1247 The unit says 21MX-E on the front, and also clearly says "E series computer". However, the tag on the back says 2112A, which was an M series machine. Odd. But further still... the keyswitch has positions operate, standby, R, and lock. This was indicative of M series machines I thought. True enough, M series were often upgraded to E series via a motherboard upgrade. But the rotary key switch is obviously still connected. And from what I've seen, M series upgraded to E they generally didn't take the time to upgrade the front panel silkscreen. I'm betting it's an M series. Or maybe an M that was very completely upgraded to an E. Anyone have thoughts on this? Regards, Jay West

Xenix 286 v.1

by SPEDRAJA＠ono.com

Hello. I've recently acquired a set of seven Xenix 286 v.1 manuals plus the OS diskettes + the Development system diskettes. These boots, even when I was not sure about its state. I should like to do one copy of them in form of virtual diskettes, in a form that permits use them with Bochs or similar emulator if possible. Problems: * Winimage (soft to do virtual plain copies of disks) can't read the disks. * The dd method under Unix/Linux give me errors. I should need to know the blocksize of the Xenix diskettes and its density (it don't appears in the labels). In appeareance the blocksize needed is 2048, but using this command: dd if=/dev/fd0 of=xenix1_i.dsk bs=2048 conv=noerrors ...returns me one message like this: 3+1 records copied /dev/fd0: error reading... 6+2 records copied ... Suggestions ? Thanks in advance Sergio

New search feature added to VCF Link Library

by vcf＠siconic.com

It's not as powerful as it could be (I'll be refining it now and then as time permits) but the search feature I just added to the VCF Link Library should make it easier to wade through the links: http://www.vintage.org/links.php My goal is to add some sort of indexing that takes into account the contents of each listed website so that searches will dig deeper into the actual contents of the sites and pull more relevant results rather than by just acting on their titles. I'm sure I can achieve this easily by utilizing Google so I'll be looking into that later. Bug reports (there shouldn't be any), comments, suggestions, questions, etc., welcome. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

New and Improved Vintage Computer Festival Link Library

by vcf＠siconic.com

I've completely re-engineered and improved the VCF Link Library: http://www.vintage.org/links.php It's a bit easier to navigate and includes more indexes for finding specialized links or sections of links. In the future I'll also add a localized search feature. In the meantime, I want to focus on adding more links and culling the dead links that are currently in the database. So, if you've got a vintage computing website you'd like to promote and it isn't already listed, add it to the Library by going here: http://www.vintage.org/addlink.php I'll be running a robot to automatically check all the links and flag the ones that are 404 for removal. If someone knows of an already existing tool then please let me know about it. I'm pretty sure my Perl Cookbook has a routine for this. Anyway, I've put a lot of work into the Link Library and think it's a great resource, and I hope you do too. It's also a way to improve your search engine rankings since the VCF is highly ranked itself. Adding a link to your site couldn't hurt. I'm interested in hearing any suggestions for improvements. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Basic Four Computers

by wlm_phd＠yahoo.com

Hi Merle - I couldn't help but respond to a posting that I saw. I'm amazed that these computers are still around. This just brings up all kinds of memories. I was one of the original development engineers at Basic Four from 1973 through 1978. I wrote all the firmware for the 1300 CPU which was an enhanced emulation of the 1200 that we bought from (I think) Microdata, in addition to almost every peripheral diagnostic, most of the drivers and a big hunk of BB2. So, if the computer museum ever needs a little background on the company or products of Basic Four, give me a yell. William L. (Bill) Miller, Ph.D. --------------------------------- Do you Yahoo!?

You did give me a filled LSI-11 card cage in that *big* pile later that might be the 11/04 your thinking about (although I thought it was 11/03 ish) otherwise you must be thinking of someone else.

Of course you'll have to cut the NPG jumper on the back of the backplane if you put an RX211 in there. -tony ------------------------------ Message: 10 Date: Wed, 17 Dec 2003 20:54:46 -0800 (PST) From: Fred Cisin <cisin(a)xenosoft.com> Subject: Re: OT: Google PI, I never knew...

Just now happened to come across it again at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2772816038&category=1247 The unit says 21MX-E on the front, and also clearly says "E series computer". However, the tag on the back says 2112A, which was an M series machine. Odd. But further still... the keyswitch has positions operate, standby, R, and lock. This was indicative of M series machines I thought. True enough, M series were often upgraded to E series via a motherboard upgrade. But the rotary key switch is obviously still connected. And from what I've seen, M series upgraded to E they generally didn't take the time to upgrade the front panel silkscreen. I'm betting it's an M series. Or maybe an M that was very completely upgraded to an E. Anyone have thoughts on this?

On the 11/45 that's all the memory the machine can address, and yes, you can have it all on the Unibus. On the 11/70, that's only a small fraction of the address space. It seems perverse to have a CPU capable of 22 bit addressing, and with fast Massbus interfaces, and then cripple it like this! I suspect you can use Unibus memory on the 11/44 too, with similar restrictions. -tony ------------------------------ Message: 13 Date: Thu, 18 Dec 2003 00:34:21 -0500 From: Patrick Finnegan <pat(a)computer-refuge.org> Subject: So I've finally got it... To: cctalk(a)classiccmp.org Message-ID: <200312180034.21984.pat(a)computer-refuge.org> Content-Type: text/plain; charset="us-ascii" I know this is OT by a couple years, but I hope you all don't mind too much ; ) After a few weeks of calling people, renting a uhaul, building a ramp, pinning myself in a closet for a while, and nearly causing much damage to my apartment, I now have what has been a dream/goal in my life: There's a Mainframe sitting in my living room. Not just any mainframe, but a nice black S/390 G3 (9672-RC4). It's got a 1996 list price that rivals the prices of houses in SoCal, and it's managed to depreciate to about 0.2% of its list price in around 7 years. And, with 2GB ram, it's got more memory on its processor than I do in my fairly fast/ capable (very OT) PC... Of course, it's configured for 3phase 200-480VAC (well, that's what it's marked on the power supplies... I'm fairly suprised that they can have that much variance)... but I've managed to get it to spin its fans and power its "Support Element" laptop with single-phase 240VAC - using the old "tie together two of the input phases to one leg of the power line" trick. I've still got to fix how the wiring job is on that is done... currently a ball of electrical tape, I'd like to stick the proper plugs back on it and get some proper outlets (which hopefully will be less than $50 apiece); that'll also let me power both the front AND back power supplies on the sucker. So, I've got the laptop booting, and the fans spinning on the S/390, but none of the boards are powered up yet.. and it's asking for a username/ password to log into the "SE" application it has, which I'm willing to bet is what will let me power up and IPL (boot) my new toy. Of course, it doesn't have DASD (disks)... something will need to be worked on for that, but it can probably come later... I'm hoping on using 'a UNIX look-alike' on it for now, and am hoping I'll be able to get the kernel booted without using DASD to boot it from. I'd have to install it from somewhere, anyway, right? Well, If anyone knows info to help me get into the SE or HMC, drop me a line, I'd be interested in learning : ). For now, I'm trying to contact the people I got it from for the info, but I'm not anticipating much luck on that front. For the rest of you, I've got some eye candy that's where I plan to put information about this thing once I get farther along with it.. http://computer-refuge.org/s390/ Pat -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/ ------------------------------ Message: 14 Date: 18 Dec 2003 01:36:14 -0500 From: "R.

Quick look inside shows it to be pretty stock, except that I was told it had some sort of silicon disk option fitted. It does look to have a memory-type board hooked up to the bus that I wasn't expecting. Currently drying out prior to strip-down and checking as it had to overnight in the car... An RM NB300 laptop. Bet there aren't many of those about (I confess to not even knowing that RM made a laptop until the guy I got the 380Z from suddenly remembered that he had it!). Looks to be fairly standard stuff inside - Conner crap-o-matic 40MB IDE drive, 386 cpu, 4MB RAM etc. but probably a quite nice spec for the time. The internal keyboard cable (one of those flat ribbons) is snapped - anyone know of a UK source for them? Othwise I'll just have to keep an eye out for replacements in broken laptops... Oh, I also got various bits of software for both machines - system disks, Windows 1.0 for the laptop etc. cheers Jules ------------------------------ Message: 22 Date: Thu, 18 Dec 2003 09:22:22 -0500 From: chris <cb(a)mythtech.net> Subject: RE: OT: I never knew...

I'm amazed that these computers are still around. This just brings up all kinds of memories. I was one of the original development engineers at Basic Four from 1973 through 1978. I wrote all the firmware for the 1300 CPU which was an enhanced emulation of the 1200 that we bought from (I think) Microdata, in addition to almost every peripheral diagnostic, most of the drivers and a big hunk of BB2. So, if the computer museum ever needs a little background on the company or products of Basic Four, give me a yell. William L. (Bill) Miller, Ph.D. --------------------------------- Do you Yahoo!?

The external winchesters where big mfm disks with a convertor board to scsi or sasi I can't remember. They are great looking machines with a BIG reset button and keyswitch. I wish I hadn't given them away. One of them still had all the server software on it to boot a network of 30 odd 480z machines which it did with ease until they replaced it with a nimbus server. On another note does anyone still have a nimbus with c-dos and the 480z network software installed on it. I have very fond memories of these >from school. I can remember when they replaced all the 480z's with nimbus's (nimbi ?). They had a few 286's when I left which I believe where around the ?2000 mark then. I know the borough I lived in (Bromley) used almost exclusivly RM machines was that the same everywhere in the UK.

shipping help from UK

by jwest＠classiccmp.org

I'm looking at getting a cpu shipped to me from the UK. I checked UPS and it says 40 pounds, 30x20x10 inches, would be about $106 to ship to me in US, 63146. I've never shipped anything from UK to US before - can anyone advise if there is a better carrier, things to look out for, etc. I'd appreciate any advice. Normally I wouldn't go to so much trouble, but it's a older PDP-11 that would particularly round out my collection :) Jay --- [This E-mail scanned for viruses by Declude Virus]

FTGH DEC Cables. (UK)

by classiccmp.org＠irrelevant.fsnet.co.uk

Hi. I've had these kicking about for a while, and I'm sure someone out there can use them; I know I can't. I picked them up in a factory that a customer had taken over. Going off the labels on the sockets, they had a microvax, so I presume these were for that. A multiway cable, big centronics style connector, with eight cables terminating in RJ45s, P/N BN26R-03 (or so it says on the plug) Two circuit boards, corresponding centronics style socket, and eight RJ45 sockets. marked 5022364-01B1T1 5422365 L1 H3117MA and 5022364-01 B1 5422365 L1 H3117MA. Pic at http://www.irrelevant.com/pics/deccable.jpg Free to good home (or first person to ask, anyway) just pay shipping; I'm in the UK, and package weighs a bit under 750g. regards Rob.

So I've finally got it...

by pat＠computer-refuge.org

I know this is OT by a couple years, but I hope you all don't mind too much ; ) After a few weeks of calling people, renting a uhaul, building a ramp, pinning myself in a closet for a while, and nearly causing much damage to my apartment, I now have what has been a dream/goal in my life: There's a Mainframe sitting in my living room. Not just any mainframe, but a nice black S/390 G3 (9672-RC4). It's got a 1996 list price that rivals the prices of houses in SoCal, and it's managed to depreciate to about 0.2% of its list price in around 7 years. And, with 2GB ram, it's got more memory on its processor than I do in my fairly fast/ capable (very OT) PC... Of course, it's configured for 3phase 200-480VAC (well, that's what it's marked on the power supplies... I'm fairly suprised that they can have that much variance)... but I've managed to get it to spin its fans and power its "Support Element" laptop with single-phase 240VAC - using the old "tie together two of the input phases to one leg of the power line" trick. I've still got to fix how the wiring job is on that is done... currently a ball of electrical tape, I'd like to stick the proper plugs back on it and get some proper outlets (which hopefully will be less than $50 apiece); that'll also let me power both the front AND back power supplies on the sucker. So, I've got the laptop booting, and the fans spinning on the S/390, but none of the boards are powered up yet.. and it's asking for a username/ password to log into the "SE" application it has, which I'm willing to bet is what will let me power up and IPL (boot) my new toy. Of course, it doesn't have DASD (disks)... something will need to be worked on for that, but it can probably come later... I'm hoping on using 'a UNIX look-alike' on it for now, and am hoping I'll be able to get the kernel booted without using DASD to boot it from. I'd have to install it from somewhere, anyway, right? Well, If anyone knows info to help me get into the SE or HMC, drop me a line, I'd be interested in learning : ). For now, I'm trying to contact the people I got it from for the info, but I'm not anticipating much luck on that front. For the rest of you, I've got some eye candy that's where I plan to put information about this thing once I get farther along with it.. http://computer-refuge.org/s390/ Pat -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/

OT: I never knew...

by dwight.elvey＠amd.com

Hi There was a talk at our last svfig ( Silicon Valley Forth Interest Group ) about how to find the interesting integer ratios ( like 355/113 ). Although, one can simply try all kinds of numbers ( quite quick on todays processors ), there are algorithms based on number theory that are faster. I wish I was paying more attention so I could pass on what was done. The talk was based on creating speciallized languages to handle these interesting problems of LSD's ( Least Common Denominator ). The fellow that gave the talk was named LaFarr. Forth is especially adapt at creating application oriented languages. I fact that is the way one normally programs in Forth, once they know what they are doing.

Macintosh security lock

by cb＠mythtech.net

>Do you remember the name of the manufacturer or company that sold them? I'm sure the kit I bought was from Kensington. I know they sell (or sold) these kits, and have (had) ones for the Powerbooks. For those it was a little cynlinder with a finger on the end. You slipped the finger into the security hole, then when you turned the key, it spun the finger behind the plastic of the case, latching the cylinder to the powerbook. Then the cable would be fed thru the cylinder (or was maybe preattached, I don't recall), and the cable was secured to some other item to keep it from being moved (desk, cinderblock, really really big dog...) I also recall a different laptop security product. It was a stick on alarm that was motion sensitive. It had a keypad on the top to type in your code to deactivate it. The idea was it glued to the powerbook, so you could put the powerbook down on a desk, turn the alarm on, and walk away. If anyone moved or touched the powerbook, the alarm would go off. I'm not sure how much use it was. If you could run fast, you could still steal it since it wasn't fixed to any object. You would just run with it beeping (stuff it in a bag full of rags and it would probably silence enough to be able to hide it until the battery died, or you could pry it off the powerbook). I'm pretty sure these only came in a glue on design, and I'm not sure when I first saw one, they might have been after the Portable was retired. So if you need something that is specific to the Portable's security hole, then that didn't help you (but it was a fun read anyway). -chris <http://www.mythtech.net>

Macintosh security lock

by cb＠mythtech.net

>I remember seeing ads for video cassettes that did the same sort of thing >... load it into your VCR when unattended, and it'd scream (seem to >remember pictures of big cats??) when moved. I've never seen them for VCRs before, but it doesn't surprise me. I have seen recently similar alarms that you can put on furniture or other items you don't want a pet on, and when it is jiggled or otherwise detects the pet (I think some are infrared detectors), the alarm goes off briefly. I did like the one I saw that was an electric pad. When the pet climbs on the pad, their weight activates it and they get a shock. I'm sure its harmless, but I'm not sure I would want to go shocking my cat on a regular basis (but I have thought about doing the same thing with the screen top to my lizard tank that my cat keeps climbing on and then falling thru). >This is of course when VCRs >cost ?400 (US$700) and not the ?29 (US$49) I've seen them recently... I just paid US $14 for a DVD player for my father for Xmas. He's been complaining he wants one, but I know it won't ever be turned on... so I bought one that was on sale, had a $10 rebate, and I used "Best Buy Bucks" from a McDonalds promotion that I had saved up. When I was done, total cost was $14. (and they asked if I wanted the $30 extended warranty on it!!!) A bit of a price difference from my first DVD player that cost me $500. Of course, I also suspect that my first player will be running happily years from now, when the $14 model has long since died. -chris <http://www.mythtech.net>

Bell & Howell - black Apple - what is it?

Just picked-up a nice Bell & Howell computer. It's very nice, and seems to work fine, but I don't know much about the history behind it. I know it's an Apple II Plus in disguise, sold to schools by B&H. Is there anything interesting about it or it's history? Thanks! Steve. __________________________________ Do you Yahoo!? New Yahoo!

Sheet-feed scanners

by aek＠spies.com

what do people recommend for scanning in terms of resolution, format etc? -- 400 - 600 dpi b&w Group 4 FAX encoded TIFFs these can be converted simply to pdf's with Eric Smith's "tumble" program. I've scanned 1 million + pages with this encoding using a Ricoh IS520 double-sided 30ppm scanner at 400dpi. All of the documents at bitsavers.com/pdf are processed this way now. Pages with graphics are scanned as 100-200dpi JPEGS but normally the text requires a bit of contrast enhancement on these pages. tumble handles mixed JPEG and TIFF documents.

So, taking the M8190-AB as baseline, and doing some arithmetic: M8190-AB M8190-AE 15MHz 18MHz non-PMI 1.0 1.1 PMI memory 1.3 1.5 18MHz is 1.2 times 15MHz, so it seems other operations on the bus are reducing the effect of the clock speed increase. Of course, that might also be due to using memory with a different cycle time. Still, it's clear that the PMI makes a bigger difference than the clock speed, going from 15MHz to 18MHz. -- Pete Peter Turnbull Network Manager University of York

Macintosh security lock

by cb＠mythtech.net

>The Macintosh Portable also has this feature. Does anyone know of, or >have, an actual locking mechanism that was made for the Macintosh >Portable? Does the portable's lock slot differ from either the Mac desktop units (like the Plus) or the laptop units (which some had a small hole that a keylock would fit into). I do have the lock clamps for a Mac Plus, and I believe it was the same as for any other desktop mac. Its a little metal bar that slips into the lock slot and snaps behind the tabs built into the case so it can't be removed. Then a cable slides thru the hole in the bar and is wrapped around and locked to any secure object. I used it to secure one of my Mac Pluses when my wife (then GF) borrowed one while in college. IF this is the same as for the Portable, then I have at least one lock plate still (it should still be in the keyboard that was used with the plus), but I'm sure I no longer have any packaging or documentation for it, and I may or may not still have additional plates or the cable. -chris <http://www.mythtech.net>

Macintosh security lock

by vcf＠siconic.com

If you hadn't noticed, most (all?) Macintosh models from the first through the Mac IIs had a slot on the back for inserting a security mechanism so that the computer could be chained to a desk. The Macintosh Portable also has this feature. Does anyone know of, or have, an actual locking mechanism that was made for the Macintosh Portable? Actual examples or documentation thereof will suffice if you've got them.

Unusual DEC module: what is this thing?

by kahrs＠caip.rutgers.edu

Just a note to say that the 1103 is what put Intel on the map (IMHO). It's a 1Kx1 memory and was also used in the Alto. It features an external "precharge" pin that was eliminated in later versions of the chip. Count your blessings.

Olivetti Luggable Questions

by nbreeden2＠comcast.net

All, I was recently given an Olivetti luggable. http://personal.nbnet.nb.ca/gallante/olivetti.html links to a page on the same model machine. With a bit of work the system is running well, it has cleaned up really well and looks to have been lightly used at best. The insides were VERY clean considering its age and the conditions it had been stored in. There is no burn on the CRT and the display is clear and crisp. :) The motherboard is labeled 'Corona Data Systems' and is serial number 0160. Various dates indicate the system was built in 1983. I find several references to 'Corona Data System', it appears they were sued by IBM and lost over copyright infringement. I'd be curious to find out if this system is one of the ones that infringed on IBM's copyrights. At boot it POSTs the following: ROM Version 1.53 Testing Complete 512K Memory Installed 512K Memory available to DOS I've been able to boot several versions of DOS, and have formatted a set of working disks. :) I'm looking for more info on it, searching the web only provides the one link listed above. -Neil

Yes, because that's about the only useful distinction -- the speed increase brought by PMI memory is more than the clock difference between 15MHz and 18MHz -- and of course if placed after the CPU, even a PMI-capable memory board operates as normal Q-Bus memory. > However, perhaps there is one area where we each > tend to have our preference.

Unusual DEC module: what is this thing?

by bshannon＠tiac.net

Does anyone recognise the following DEC module? HIGH SPEED MOS MEM MAT MS1440 G401C This is THE most unusual DEC board I've ever seen personally, and also the most beautiful. This board has an extreamly early example of an LED in the upper right hand corner where a machined metal stiffener is used in place of the usual cast part used on other Unibus boards. This stiffener appears to have been milled out of an extrusion, by hand. Nylon hardware is used along with the more conventional eye-ring rivits. The outside edge of this milled part is stamped 'G401'. This LED is made from a gold-clad machined metal case unlike anyI've ever seen (including those seen on the LED museum web site). I can't see the part number on the case, but I'd bet its a Hewlett Packard. This LED alone may well be worth more than the whole module! The IC's are an orderly mix of grey plastic, gold leaded Intel P1103-1's, and gold on white ceramic (with grey lead-frame traces) Intel 3207-1's. Arrays of individual resistors form high speed DC terminators for the arrays of 1103's and 3207's, and a small handful of TTL parts complete the list of chips. The TTL datecodes suggest its from 1970. The memory chips are not so easy to understand, the P1103-1's are marked: P1103-1 0531 And the 3207's are marked: 3207-1 S183 B0536 Both feature a large 'i" logo to the left of the markings. Clearly very early Intel parts. I suspect that this ~may~ have been a 'live spare' for a PDP 11T55 I once owned and ran many years ago. If anyone knows what this board is, I'd love to know. I can try to get a digital photo made, but that may take some time. If someone 'just has to' own this board, I'm willing to talk. The overall condition of the board is excellent and very few of the decoupling caps have scratches from installation and removal. The unusual edge-stiffener also shows unusually little ware.

You can use a SCSI 9-track drive to create a tape on a simulated system and carry it over to an 11 with a tape drive. If you don't have an MSCP SCSI drive on the 11, other mass storage devices don't have interfaces on the simulated system. If you DO have an MSCP controller, a ZIP drive is the easiest shuttle media. Stick one drive on the 11, one on your system with the simulator, and use John's DO driver to pull the bits over to the simulator's host OS. I with SIMH had the equivalent (esp in the VAX world)

Three Days of the Condor

by SPEDRAJA＠ono.com

Yes, one of my preferred movies about spies of the seventies. Some teletypes, terminals and even Dectapes, i think. Another interesting movie with some old computing items is "The Falcon and the Snowman" (music of Pat Metheny and David Bowie, with Sean Penn and Timothy Hutton). There are some scenes of Hutton in one room of the CIA using old teletypes ASR33. In Science Fiction field, I like two movies specially with some computing interaction: "Colossus", and "The Andromeda Strain".

The MK memory cables were often the cause of multiple problems and the multiport version set up on a bunch of conjoined 11/70-type boxes would've been a nightmare. XXDP+ would've had to be loaded into a shared memory partition and it would've been a large PITA for the systems manager to have to do that while it was running. They could've required a preloaded diag monitor that could've been switched to the down box, though to get around this. Anyway, the 11/782's were large pains only when the SBA interconnects went bad which was a fairly rare occurrance when the machine was fully installed. The SBI cables were about 4 inches long... the 12-18 inch ones were used between cabinets. How many feet of MK cable would that have been! The MK cables were often nicked, cut or just plain and could've been sliced by tiles in multcpu configs... etc. I used 1/4 of an 11/74 at DEC Princeton. A nice pretty front panel and I'd have loved to work on one full-up. But maintaining it would've been a PITA. BIll pechter(a)monmouth.com

I reached a milestone, so thought I'd share :) I now have two HP 7906 drives working flawlessly. 5 more to go. But instead of working on the others, right now I'm going through and running diags on each board in the 13037 controller... meaning of all the 7 or 8 13037 boxes I have, testing each card one at a time in a known working 13037. What fun. Very time consuming, but, when I go to work on the next drive, I can at least know any problems I run into are the drive rather than the controller. I'm also testing all the cards in the drive one at a time with cards from the other drives. Life is much better when you have two of an item to use as a testbed. I do have a 7905 as well... that one will probably wind up on the trading block - after I check it out and make sure it works. Anyone want a 7912? Heavy beast, and HPIB only so I have no interest in it. I think I'm going to go back and change my HP2000 Access system rack configuration. Move the paper tape reader and paper tape punch to the other side of the dual bay rack, and mount a 7906 in the spot where they were. Masochistic I tell ya. Well, this is all a milestone for ME at least, because I've always been somewhat "afraid" of working on 14" hard drives. But I think I'm getting the hang of it :) Well, diags just finished on the ECC board, time for the next card. Cheers Jay

DG Aviion 88k software/dumping disks...

by drido＠optusnet.com.au

I've got a DG Aviion 4000 (Motorola 88k based) here. I've never had it up and running as it came here without RAM. I want to pull the hdd to use in another machine. Before I reformat this HDD is anyone interested in the software that may be on it? If you're local (Melbourne, Australia) the easiest way would be to take the HDD and give me another 1GB SCSI HDD to replace it. Otherwise what's the easiest way to dump this disk to an image file on a DOS/Windows PC? I don't have anything running linux at the moment, so to do it under linux I'd need to be able to do it without having to actually installing linux... boot from a CD, write the image out to an existing fat32 formatted HDD.

Sheet-feed scanners

by tomj＠wps.com

Though hardly less than 10 years old, it's on the topic of old machinery... A limiting factor for me (and I'm sure others) to put up 'obsolete' documentation is hand scanning. Does anyone know of an inexpensive sheet feed scanner that will accept 50+ sheets? These "all in one" type things, like HP Officejet, only accept 10 sheets at a time, and do a poor job. Inexpensive meaning here a few hundred $US. Every few months I look and never find anything between the officejet and $10K large-office machines. With a decent feeder I'd saw bindings off to sheet-feed manuals and books I have duplicates of.

Building a PDP-11 for the first time

by chrisc＠addpower.com

Finally! Instead of just working on one, I'm going to try to build one >from some components that I've collected. Trouble is, I'm not sure how to put it all together. I saw mention of a QBUS howto, but the link to that seems to be long gone. Would a kind soul care to assist on this? This is what I have: BA23 enclosure M8190-AB (11/84 cpu) M8067 (512k memory?) M7516 (DELQA) Dilog DQ686 (ESDI controller) Maxtor ESDI drive (don't remember how large offhand) I'm thinking that I have all that I need here, but I could be wrong. I want to be able to run 2.11BSD on the machine... Cheers, Chris Cureau

I doubt it was an official designation, it's just what we (CFM) called them if they were in BA11-N boxes. The microPDP-11/73 machines in BA23 boxes always used the quad board, or course, so we never needed to distinguish. > >From what I understand, for the PDP-11/23 boards, the > "PLUS" could mean either the ability to address all 4 MBytes > of memory with the dual M8186 boards (I understand that > the original M8186 boards were able to address only 256 > KBytes) or that the quad M8189 board was being used.

The 11/73 never had the same boot ROMs as an 11/83 unless it was upgraded (which was quite common). > So the dialogue for the PDP-11/73 and the PDP-11/83 can > be identical - it just depends on which version of the > EPROMs is being used. Of course. The dialogue is in the ROMs, after all, and people did upgrade them (to get the ability to boot newer devices, for example). > All this discussion seems to point out that the PDP-11/73, > PDP-11/83 and PDP-11/93 boards were not identical I disagree -- I don't see anything to differentiate an 11/73 board from an 11/83 from an 11/84, except the clock and the boot ROMs. Sure, different revs of J11 were used. The original spec was for a 20MHz or 25MHz chip but it didn't meet the spec. Sure, there were FCOs and ECOs, but they applied to both 11/73 and 11/83 (and presumably 11/84). You've shown yourself exactly what I said, that if you use PMI memory, the system thinks it's an 11/83 and if you use non-PMI memory, it's an 11/73. > nor did they use the same J11 CPU chip all the time, although > the last 09 rev CPU chip that was used with the PDP-11/93 > would probably work with all of the others, just NOT the > other way around with the early 04 rev CPU chips.

No, not true. There are both dual and quad 11/73 (the quad being an 11/73-plus). The 11/73 was 15MHz, the 11/83 was always sold as 18MHz. > OH, and the 11/83 has a very nice verbose Boot-PROM ;-) So does the 11/73, though it's different.

Older IDE drives

by teoz＠neo.rr.com

Whats a good place to buy a few 500mb and 2gb IDE drives for projects? I have a 386 limited to 512mb and have a 486 that tops out at 2gb for dos and wanted to test a few older OS on them but ran out of drives. I need maybe 2 of each size dont care about brand as long as they are 3.5" hh drives (I have removable IDE cariers for them). Looks like 6-8gb is the low end size liquidaters on the net are selling.

Tax Free Musuem?

by jrice54＠charter.net

I seem to remember someone was attempting to gain a non-profit museum status from the IRS for their collection. Were they successful and what was the total out come? Was it worth the effort? Would they recomend the process for others? Was it worth the hassles of filing paperwork regularly? I know it's a lot of questions. My collection is out growing my available space (don't we all have this problem?), so I was wondering about options. James -- http://webpages.charter.net/jrice54/classiccomp2.html

MicroVAX II question

by jwillis＠coherent-logic.com

Rackmount MicroVAX II given to me by a local PCB manufacturer. When I went to pick this machine up, it worked at their location. Booted into VMS and everything. Took it out of rack to transport home (they would not give up the original DEC rack). I marked all cables before disassembling, and put it back together in the same configuration. Got it home and the system would not get past the "3" stage of its self test. Any ideas?

Reel-to-Reel care?

Whereas, Al Kossow wrote: >The long term prospects of tape transports with any rubber parts is not good, either. >Almost all of the 1/4" cartridge tape drives I own are inoperable because the drive >pinch rollers have turned to goo. Now therefore: I?m left to wonder of these rubber parts could be recast. I have had success casting rubber using Devcon flexane. It?s a 2 part mix with extremely low shrinkage. The medium ?80? liquid has a companion softener flex-add which allow one to adjust the hardness of the resulting rubber. I have used Freeman machinable wax to make molds with good results. I would think that with reasonable machining practice a run-out of a thousandth or so could be had re-rubberizing a roller spindle. (A human hair being about 3 thousandths of an inch) If greater precision were required a machining allowance could be added to the rubber and it could be frozen and ground after casting. (Not that I would look forward to liquid nitrogen all over my south bend lathe, and it?s not like we?re making disk heads here) The bottom line is that if it was made, it can be made. After all, some telescope hobbyists make their own mirrors! Your thoughts? Mike.

Not necessariliy, or to put it another way, both are correct. The J11 is a chip , used in several PDP-11 variants. The M8190 is a processor board used in 11/73, 11/83, and 11/84. The difference is (1) the 11/73 originally had a 15MHz clock, and the 11/83 and 11/84 had an 18MHz clock, (2) the 11/73 and 11/8x had different ROMs, and (3) in an 11/73 system the memory is arranged after the CPU in conventional fashion, whereas in an 11/83 the memory is PMI memory and is placed before the CPU. There are several revisions of the ROMs for the 11/8x, and the second letter of the suffix (the first is always 'B') tells you what the original ROM version was. This is a quad-height board with two bootstrap ROMs (actually EPROMs), line time clock, and two SLUs. All M8190s are the same (modulo engineering change orders etc) apart from crystal and ROMs. The M8192 is always an 11/73; it's a dual-height board with no SLus or ROMs, etc. It was usually sold as an OEM item or as an upgrade for 11/23 systems. There ar a few variants of this too, becasue there as a bug in early versions of an ASIC which meant that some early ones would not work with an FPU upgrade. All these boards are Q-Bus boards. There is no Unibus version. The 11/84 used an M8190 in a backplane with a Unibus converter (the CPU and memory were Q-Bus, the rest of the machine was Unibus). The 11/94 worked in a similar way. However, Eric may be right about the 11/84 bus being slightly different from normal Q-Bus, so that the official 11/84 memory may be different. -- Pete Peter Turnbull Network Manager University of York

WTD: LC1552B, ITT 492-5 and NatSemi NSA298 data

by philpem＠dsl.pipex.com

Hi, Someone's just given me a Commodore Minuteman 3MW (model MM3MW) calculator. The device itself is working fine, but I still need to replace the battery pack and charge connector (the batteries were rechargeable nicad, N size). Anyway, just to satisfy my curiosity, I'd like to get some data on the ICs used inside it - these are: LC1552B / 7438 - looks like the main controller. Has some strange logo I've never seen before - kind of a _/- (a squared off S?) with a circle printed over the top. ITT / 492-5 / 7445 - these appear to be LED drivers. I've never seen a part number like this. BTW, the "7445" is printed vertically, the rest of the p/n is printed horizontally (as normal). NSA298 / NS 436 - the "NS" looks a LOT like one of National Semiconductor's old logos. Did NatSemi ever make LED display panels? Now, to finish satisfying my curiosity, does anyone know anything about the Commodore MM3MW? A schematic diagram or service manual would be nice :) Thanks. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)dsl.pipex.com | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.dsl.pipex.com/ | 48xCD, ARCINv6c IDE, SCSI
