Sent to the list, because your email server reckons that I am a security or content violator... Timothy, Thanks for that - two is because I have 2 11/04 systems. At this stage, Curt from the atari museum has offered me one that will get me out of strife. If I end up being able to get both systems fully operational, I'll give you an email (probably via the list :-) ) . Doug

Any word on OS/2 for PDP-11?

by aek＠bitsavers.org

My last comment on this bit of absurdity is >from Bob Supnik, who would have been in the position to know as one of the senior VAX engineers in the 80's. I didn't even bother asking if a PDP-11 version of OS/2 existed. -- No, there was no VAX version of OS/2. And a luggable wasn't done on my watch. No idea who Dan Gahlinger is, either. Does he have a "VAXmate" (which was really a PC, and could run OS/2) confused with a VAX? Now, if he means "luggable like a Rainbow", which was just a PC chassis without keyboard or monitor, then there were tons of those - every VAXstation looked more or less like a Rainbow, since they all came out of the same industrial design group ("any color you want, as long as its beige"). If he means a real luggable, with a built in monitor and keyboard, I never saw one. But the VAXstation 2000 was fairly small, only slightly bigger than a DECmate, so repackaging it with a fold out keyboard and a small monitor would have been possible, if some government group wanted one. /Bob

PDP 11/04 -> 11/34 Conversion

I have recently become the proud owner of a PDP-11/04 with a set of 11/34 cards (M8266 & M8265) This particular 11/04 has some stuff on an extension backplane that I don't understand: PDP11/04-LH configuration UNIBUS layout: A B C D E F M7263 M7263 M7263 M7263 M7263 M7263 1 M7891 M7891 M7891 M7891 M7891 M7891 2 blank blank blank GRANT blank blank 3 M9312 M9312 M7859 M7859 M7859 M7859 4 M7762 M7762 M7762 M7762 M7762 M7762 5 M7856 M7856 M7856 M7856 M7856 M7856 6 blank blank blank GRANT blank blank 7 M7856 M7856 M7856 M7856 M7856 M7856 8 M920 M920 blank GRANT blank blank 9 ------------------------------------10 M920 M920 M7219 M7219 M7219 M7219 11 (- M9688A-) M208 M208 M7821 M796 12 PWR M205 M611 M611 M112 M113 13 M9302 M9302 blank blank M116 M239 14 The M9688A is a very short card - titled DR11-B Test Board The stuff in slots 11-14 is what I have no idea about.

Does anyone have any info or experience with either of these plasma (thin flat screen) displays/terminals? There's no keyboard: just a touch-screen and RS232 interface.

32 sector 8 inch floppies

by Watzman＠neo.rr.com

Re: "I just found a box of about 15: 8 inch floppies 32 sectors (hard sectored) Double Sided Single Density. Some are TDK F1-H. Any takers?" These are used in the Processor Technology Helios disk system (intended for, but not really specific to, the SOL-20 computer). I have what might be the last two such operational systems in existence, and I have to say that carefully because they have not been powered since 2004, when they were working and booting PT-DOS. However I have several boxes of the diskettes and don't really need more.

Yes; there are some Morrow / Thinker Toys memory boards that have never appeared anywhere, not even Herb has them in his files (and the boards do exist, I have some of these). Because they are "Thinker Toys", I'm not sure if they would be in what you received or not.

Massive lot of vintage hard drives

by sellam＠vintagetech.com

The Great Vintage Disk Drive Jubilee!! I have a friend in town (Shrikant Desai, some of you may have seen his talk at VCFX last year) who has a huge collection of vintage to modern disk drives, including floppy and hard, magnetic and optical, 14", 8", 5.25", 3.5", 2", etc. His collection of drives numbers in the hundreds, possibly breaking the 1,000 barrier (everytime I turn a corner at his house I find a new stash, and he has other stashes around town). His informal goal was to create a comprehensive archive of every drive ever made. He thinks he has attained about 60% of that goal. There is definitely overlap and duplicate units.B Alas, Shrikant is getting on in years and no longer has the time or energy to maintain the collection. We had been trying to jointly start a computer museum in town to feature a conglomeration of my and his collections, but because of time and budgetary constraints we reluctantly abandoned the idea (for now at least). So Shrikant has decided to divest himself of his drive collection. The collection was a typical pack-rat pursuit, borne out of intellectual curiosity as well as an inherent urge to archive stuff for posterity. Shrikant has worked for almost every disk drive manufacturer from the 1960s through to current day in one form or another. For example, back in the 1970s and 1980s he was Directory of Technology Development at Shugart. The Computer History Museum already came out and took a few boxes of materials away (mostly documentation) so we're left with a huge pile of metal. Shrikant asked me to help disburse the remainder. At first I was thinking purely scrap, as my mindset these days is hued by my electronic recycling business (don't worry, nothing vintage/classic gets scrapped) and a great majority of the collection is modernish drives (MFM and IDE) but then I started to realize these are drives that other collectors may find useful to get or keep their vintage systems running, especially the older and rarer ones. If it hadn't been for the trouble I had trying to find a working ST-225 for an IBM PC 5150 I put together recently for a project I may not have given this the consideration it deserves. I came to the realization that it's hard to find working vintage hard drives these days, which is kind of a "duh" realization since that's pretty much a given. So, in the interest of helping both Shrikant and fellow collectors, I decided it would serve everyone's interest to offer the drives up for sale. I've set up a special request form here: http://www.vintage.org/special/2008/diskdrive.php On this form you are asked to enter your name, e-mail address, the drive(s) you are seeking, and the price you are willing to pay. The way this will work is we will give time for people to submit requests, say a couple weeks, then we're going to start going through the drives and identifying ones that have been requested. We'll try to determine if the drive is good or not using simple tests (i.e. visual inspection, shaking, and other highly technical considerations), but this will by no means guarantee the drive is working. This will be an "as-is" sale, so make your offer accordingly. We are not seeking huge sums here, just enough to cover time. If you want a known good drive, please note this in the request and make sure your offer takes into consideration the time and skill required to find a proper host machine, hook everything together, then run diagnostics, etc. It took me 22 hours to build the 5150 referenced above, a large portion of which was spent locating, testing, and troubleshooting a working ST-225. If you want to pay only $20 for a known working hard drive, that's not going to fly. Really, all I want to do is find the drive you're looking for, package it, then ship it to you. If you want a known good drive, we will have to discuss it as a consulting project, and I'm not cheap (and niether is Shrikant). Also, between you, I, and the mailing list, Shrikant could really use the money right now. Shipping costs (actual, via Fedex Ground) will be added to your offer. We will need to collect from you before we ship out the drive. PayPal is best, checks sent to me are fine. We'll discuss the details further when the time comes. The reason I want you to use the form and not to e-mail me a request is because my inbox already has 1,500 mostly unanswered e-mails in it and I tend to "lose" messages amid the deluge (I periodically try to knock down the backlog and at one point had it down to less than 1,200 but it has gained on me in recent weeks). So it would behoove you to use the form to make your request since that will be easier for me to manage and track. Do feel free to e-mail me directly if you have a question that can't be entered into the form but please keep in mind that I'm so busy these days I might not be able to respond right away. PLEASE NOTE: I do not follow the CC list regularly. I am subscribed but have delivery turned off. I scan the archives periodically to see what's being discussed but don't have time to actively participate. That being said, please send any relevant replies or inquiries to me directly, not to the list, or else there's a good chance I won't read it. Lastly, I'm sure I'm missing some details or something, so I'll follow up once I've had a number of people e-mail me asking me for obvious information that I've neglected to include here.

Cardboard Computer: Cardiac! New-Old-Stock

by tpeters＠mixcom.com

Imagine my delight upon learning that there is NOS available of CARDIAC: Cardboard Illustrated Aid to Computing, the Bell Labs fold-flat computer that taught me so much about assembly language computing. Hurrah! In 1961, Bell introduced four kits to aid science education at the high school level. In 1968, they made a fifth kit available, called CARDIAC. Get 'em while their hot-- stock won't last long. I don't think these prices are accurate anymore, there's an email address for inquiries, since the company is going out of business. CARDIAC, $19.29, and Vu-Graph for CARDIAC $22.95. I have no idea what a VuGraph might be and don't think I've ever seen one. But I still have my trusty CARDIAC, given to me by my 5th grade teacher at the end of the year. http://www.boingboing.net/2008/03/11/newold-stock-of-bell.html http://www.porticus.org/bell/belllabs_kits.html ----- 189.

of the early French computer SEREL ODP-505 (germanium CPU)

I have looked on the 'Big List' to find the date it was first sold but could not find it. Google only brings up pages in the French language. Could you please give us the year? It is tiny compared with my Germanium machine (ICT 1301) which weighs five tons. It has the same clock speed but is quite a bit slower, so I guess it is earlier than mine. But maybe the emphasis of the design was miniaturisation and the designers traded speed for size. Roger Holmes (Kent, England)

Intel hex file loader in asm80

by jefferwin＠gmail.com

Ok, ok, I know I can just sit down and write one, but I know that a zillion of these have been written over time. I need an asm80 simple program loader that will take in the ascii stream >from an intel hex file, parse it, convert the data to binary and put it in memory. The source doesn't matter, the loader portion can be from a floppy driver, paper tape reader or whatever, I can easily change the source, I would just like to not have to write all of the parsing stuff for the hex format. Anyone have any asm80 source that might include the loader portion? Jeff Erwin

I haven't tried a 4mm DAT tape yet, but I was able to install DECnet/E 4.1 from an 8mm tape using an EXB-8200 SCSI tape drive connected to a TTi (Transitional Technology Inc) QTS-3 SCSI TMSCP controller to verify that that drive and controller combination works with real DEC software. I initially thought that drive and / or controller combination was not working correctly as I could never get 2.11BSD installed using it. Now I think it is something in the 2.11BSD installation tape 'boot' binary that probably has some TMSCP assumptions that are not always true on all controllers. I had the same problem with 2.11BSD using a CQD-200/T (aka MTI QTS30) controller, while a CMD CQD-220/TM worked fine.

In which I further expose my ignorance: What is this electronic component?

by derschjo＠msu.edu

So I'm cleaning out the Ergo 201 terminal I mentioned earlier (and preparing to do a cap kit on it since it needs it) and I've run across something that looks kind of like an electrolytic capacitor on a diet. I'm unable to identify it and I feel like an idiot :). At any rate, it appears to be leaking something so I'd like to replace it, once I can figure out what it is. Wish I had a schematic for this thing. Here's a couple of pictures of it: http://yahozna.dyndns.org/scratch/mystery-1.jpg http://yahozna.dyndns.org/scratch/mystery-2.jpg Any ideas? The only markings on it are: 1019 8320 TWN on one side, and C-H-L TDK on the other. The positive terminal is labeled (which is the opposite of most capacitors I've seen...) Any thoughts? As always, thanks... - Josh

D-shell hole punches?

by tiggerlasv＠aim.com

Usually, when I need a template for a DB25, DE9, or whatever, I just dig in the junk box for an old PC-type serial bracket. You know, from back in the day when the serial ports were in one of the blank spots for empty card slots, instead of being on the motherboard itself? Naturally, I'd prefer a punch myself, but as everyone agrees, they are kind of pricey. Fortunately, I've never really needed one that often, that I couldn't deal with using a nibbling tool. Depending on how you're planning on mounting it, the hole may or may not need to be perfect. If you're putting the D-connector BEHIND the panel / chassis, then you'll want a nice, neat opening. Although it's not as pretty, you can cut a rectangular opening with a screw-hole on each side, and mount the flanged portion of the D-sub on the OUTSIDE of the chassis. If you're careful, the metal frame of the D-sub will cover up any imperfections in the size/shape of the opening. And lastly, the "down and dirty method" is to cut a 3" x 1/2" rectangular opening, and use one of the afore-mentioned PC brackets from behind for mounting. I know. . . not pretty, but sometimes handy when working on a chassis with existing knock-outs/holes which need covering anyway. T

Tektronics 4051 collection -- on craigslist in austin, texas, usa, earth

by frustum＠pacbell.net

Full text of the message, although the listing also contains a scan of a manual cover: My dad bought & used the 4051 series computers for many, many years, and accumulated several 4051 computers, peripherals, etc. He bought his first one in 1976, it was an amazing computer! Believe it or not, he was still programming the beast until about 3 years ago. So several of these computers still work. These things are RARE as hen's teeth now, and he has a lot of parts, even a screen for one that is new-old-stock still in the box (this is the computer that had the cool vector graphics screen!). I don't have pictures yet, but will get some. I want $2000 bucks for the whole collection of stuff. great find for a collector/tinkerer, as these don't show up very often. cash only, no checks. http://austin.craigslist.org/sys/604555003.html As the URL says, this is in Austin, Texas. $2000 seems kinda rich to me, but maybe to someone on this list it is worth it. I watch austin craigslist frequently and vintage computer gear doesn't show up all that often. I am not the seller; I don't know the seller; do your own vetting. Sorry, I'm not available to pick this up and ship it to a non-local buyer. Contents may settle during shipping. Your mileage may vary.

I use a spiral cutter and a template. I picked up a cheap spiral cutter from my neighborhood China Town store and modified it by adding a template follower to the head. I generate the template on a cad program, expand it twice needed and print onto card stock which I then hand cut. I use this template to cut the final template in plastic. Drill a hole at the cut-out site, clamp the template on the target piece and cut away. You should ensure that you get a metal cutter if you are doing steel or aluminum (aluminium). I found that taking two steps to generate the template results in a much better result. My cutter was bought on sale for under US$ 20 for a one-off job and kept around and modified when I ran into a situation that needed a odd shape cut-out. A good cutter will run under US$ 75 and the bits are on the order of 5-10. I've used it to do D-holes for BNCs and power cords, connectors, as well as many other openings such as for fans. CRC

Is there a tape loader for use over a 12531? Also, I'm using a modified version of the perl assembler. I'd like to actually use the native HP assembler under SIMH. The HP / CHM agreement should allow for at least this much bootstrap information to be shared. I'm happy to put up bootstrap instructions and tape images if someone can provide them. I don't have any other peripherals tested out yet. Not sure why my real paper tape reader is not working yet. My paper tape punch is a long ways >from working and it's not HP equipment anyway. I've got tape images that work in SIMH like the HP-Basic. Just want to see these work on real hardware by loading them over a serial line. There are quite a few HP collectors out there. How do you folks boot up your hardware? ok, I could get an HP-7970 9 track, but I don't have that either. It would seem useful to be able to bootstrap any given tape over serial. I know it's only 2400 baud, but just about every HP collector should have the needed hardware. :) Help me out!
