Hi Mark ! Ran across your 2016 note at ( http://www.classiccmp.org/pipermail/cctalk/2016-July/025530.html ) while looking for info on the HP9885M Disk Drive. I have one of these old drives in what appears to be near mint condition. I can't fully test it, don't have any disks, but it powers up without any magic smoke leaking out. LEDs lit up, capstan drive is working, belt is in pristine condition, ventilation fan is working, boards are powered. Certainly looks like it's ready to go. I've carried the thing all over the country as I've moved between jobs, intending to use the chassis in construction of a different electronic device. It has spent a lot of time in closets. I don't have an HP9825A or HP9845 computer and I'm getting too old to acquire such toys. If you have interest, I would like for someone who understands and appreciates such things to have it. I can share pictures. It would be a shame to disassemble such a well-built old beast. Please let me know. Have a great week! Ernie K7KT at yahoo.com

What platform can run m68k COFF binaries?

I remember messing around with it when porting an old version of gcc to the machine. At that time, GNU was playing around with something called robotusin (COFF medicine). BLS

VMS Mosaic 4.2

by spectre＠floodgap.com

I'm worried that VMS Mosaic 4.2 is lost since WVNET's VAX systems are no longer operational, and it was stored on their FTP server (not somewhere that the Wayback Machine got to). I only have an old version of 3.6 and a diff of 4.2. Does anyone have the original copy of 4.2? It was named MOSAIC4_2.ZIP.

AlphaWindows - Protocol Information?

by Martin.Hepperle＠MH-AeroTools.de

In the 1990s a computer terminal standard "AlphaWindows" was proposed by the Display Industry Association (DIA). Sort of X-Windows for the poor. A few terminals appeared which supported multiple text windows following the this standard. Some limited global facts can be found in Wikipedia. I learned that for example the TeleVideo 995 and 9089 or the HP 700/70 terminals supported AlphaWindows. Obviously there were several implementation levels like: (1) Basic AlphaWindow (2) Mouse Operations (3) Decorations (4) AlphaWindow Credits Flow Control Unfortunately I cannot find any information on the protocol resp. escape sequences and the DIA is long gone. Does anyone have a manual with escape sequences for one of the terminals mentioned? Or other material describing this protocol? Note that other terminals of the similar types (e.g. HP 700/71) do not support this feature. Martin

It so happens that I do have a copy of the standard. I suppose I'm one of only a few who paid the $99 to DIA to get a copy. Back in the early '90s I started writing an implementation for the Mac, but ended up not getting very far before other projects pushed it down onto the stack. I'll see what I can do about scanning it for you. BLS

Milwaukee Computers MC-1200

by aek＠bitsavers.org

Another small project off my plate. Ethan had asked me years ago to make copies of the software for this machine. It is pretty obscure, one full page add in Byte, and it sank without a trace. 6502, p-System, totally custom MFM-encoded floppy interface based on a Moto 6852 synchronous serial interface chip. I had bought a Supercard Pro a while ago, and set it up to do some hard-sectored floppy imaging. Figured this would be a good test case, since it didn't have the problems with dealing with out of sync data streams (the SCP doesn't grok more than one sector hole so you have to turn off index synchronization). Made images, dragged my machine out of storage, cleaned it up, made a clone from the SCP image, and it booted! yay! SCP images are up under http://bitsavers.org/bits/MilwaukeeComputers I also put up cleaner images of the schematic and board layout, and annotated a disassembly of the boot prom from a scanned listing i've had for a while under http://bitsavers.org/pdf/milwaukeeComputers One thing I noticed that made me nervous is looking at the code there is no checksum on either the sector address or data fields on the floppy. I made an image of a floppy that I bulk-erased and initialized this morning, and all you see are the sync bytes and data, no trailing data where a crc would be.

Dilog DQ604 RL01 / RL02 emulation on ST506/ST412 disk.

by mattislind＠gmail.com

I unearthed some old TU58 tapes that luckily was readable (after carefully replacing the tension band) It resulted in two RT11 V4 images with two versions of the formatter program. One is bootable and the other not. http://storage.datormuseum.se/u/96935524/Datormusuem/Dilog/DQ604/sq604c.dsk http://storage.datormuseum.se/u/96935524/Datormusuem/Dilog/DQ604/sq604d.dsk I tried to run the formatter program in Simh: .run sq604C.sav TEST AND FORMAT DQ604 DISK SYSTEM (REV C.) DRIVE FORMATS AS RL01 UNIT (5.24 MB) SWITCH 3 CLOSED ENABLES BOOTSTRAP THERE ARE 17 PHYSICAL SECTORS PER TRACK (2) ALTERNATE CYLINDERS MAY BE ASSIGNED PER UNIT THE INTERLACE FACTORS ARE TWO OR THREE TO ONE DATA BUFFER ERROR USE PROCEED (P) TO REPEAT TEST HALT instruction, PC: 006312 (BR 6202) .RUN SQ604D TEST AND FORMAT DQ604 DISK SYSTEM (REV C.) DRIVE FORMATS AS RL02 UNIT (10.48 MB) SWITCH 3 CLOSED ENABLES BOOTSTRAP THERE ARE 17 PHYSICAL SECTORS PER TRACK (4) ALTERNATE CYLINDERS MAY BE ASSIGNED PER UNIT THE INTERLACE FACTORS ARE TWO OR THREE TO ONE DATA BUFFER ERROR USE PROCEED (P) TO REPEAT TEST HALT instruction, PC: 006312 (BR 6202) So it appears to be runnable. I also found the manual for the board and scanned it: http://storage.datormuseum.se/u/96935524/Datormusuem/Dilog/DQ604/DQ604.pdf Now the next step is to see if this can make the DQ604 board I have working with David Gessweins MFM emulator.

Free: Dell Poweredge 2950

by sieler＠allegro.com

Anyone interested in a free dell poweredge 2950? (Free for pickup in Redwood City, CA, USA) Two 73 (?) GB SAS drives, some amount of RAM. Worked the last time it was powered on, about 2 years ago. No idea how much memory or other features. It was bought (used) to be a spare for another Dell, but once we realized the original Dell used SATA drives, we never used this one. We're moving offices, and this has to find a home or a scrapheap. (It was introduced about 2006, so that makes the 10 year classic cutoff :) thanks, Stan

WTB: Altair 680, Any Condition, Any Configuration

by systems.glitch＠gmail.com

All, I'm looking for an Altair 680. I've been working with Jeff Albrecht's A680 during the RAM board design process, and would like to continue working on a few things for the 680, but I'd also like to send Jeff's machine back to him! Configuration is not particularly important to me. I'd like something with a non-rev 0 motherboard in it if possible -- the easiest way to tell is that there will be a slot for the expansion riser. Front panel vs. turnkey, branding, etc. are not important to me. I'd potentially be interested in even an empty case! Thanks, Jonathan

Thicknet/10base5 Test Segment: The Cable is In!

All, A few months ago, I mentioned one of my suppliers had Belden 89880 thicknet Ethernet cable. Well, last week I finally made it down to his warehouse and picked it up! The final bits for a test segment came in today, so I set up a little link between my SPARCstation 10 and DEChub 90: https://imgur.com/a/GDUR36j Anyone interested in cable can email me directly (please change the subject line, it'll get binned into my cctalk folder otherwise). I can provide any level of "kit" from just the cable to fully ready to go. I do have a very few NOS Cabletron ST-500-01 transceiver/non-intrusive tap kits as well. Thanks, Jonathan

PDP-11/04 on eBay

by jnc＠mercury.lcs.mit.edu

For those who didn't catch it: https://www.ebay.com/itm/202415330983 I have bought from this seller before (very happy with the results), but am not otherwise affiliated. The -11/04 is a nice UNIBUS starter/test machine (my UNIBUS board debug machine is an -11/04). The CPU is a single (hex) board, and it's really simple and straightforward - very easy to work on and fix. (You don't even need to put it on an extender card! :-) Depending on the backplane that's in the machine, it might be super-easy to upgrade to an -11/34 (if it's a DD11-P, as many /04's are, just pull the CPU card and plug in a set of /34 boards). Not sure what's up with the M105/M7821; they aren't standalone cards, but go with some other card (they are addressing and interrupt/vector functionality). No idea what it was, though... Noel

DEC PDP 11 RK05 DEC custom (?) bootstrap board

by jnc＠mercury.lcs.mit.edu

> From: Paul Koning > the original ROM array bootstrap supports not just RK05 but also RF11, > RC11, and TC11 in just 16 words of code. Ah, the days of devices that just did what they were told without trying to be effing rocket scientists about it! (Yeah, yeah, I know _some_ of the things the later ones did, you had to be close to the hardware to do them, but too often they had this 'we're from the device manufacturer, and we're here to help you' thing going. I used to have a photocopy of a great article in a trade rag which explained why complex devices were a Bad Idea; maybe I can find it, if anyone's interested.) Noel

11LOGO

by lars＠nocrew.org

Hello, I have a 1972 version of 11LOGO, which is the dialect of Logo which was done by the Logo group at MIT. Their computer was a PDP-11/45. I have it running in a PDP-11 simulator, 11SIM, which runs on the ITS operating system. If someone is interested in running it in some other simulator like SIMH, I can provide files and assistance. The nice thing about 11SIM is that it emulates the one-off TK display system which provides 8 vector displays. 11LOGO uses it to view turtle graphics. It would be interesting to add this capability to SIMH, but I'm pressed for time. I can provide documentation, though. There is a second application, the Dazzle Dart game, which uses this display as well. It doesn't run in 11SIM because it uses FP11 instructions which are not implemented. Best regards, Lars Brinkhoff

It also came with the QuickWin libraries to create FORTRAN programs which output text and graphics in Windows. I am not 100% sure, but it is possible that the first release did not have the QuickWin libraries and it came with an update. When you install Microsoft FORTRAN 5.1 you have the option to install the SAMPLES. The README says: <cite> [...] \SOURCE\SAMPLES This directory also contains the source code for the graphics programs from chapters 11, 12, and 13 of the Microsoft FORTRAN Advanced Topics manual. Note that these examples require the graphics include files FGRAPH.FI and FGRAPH.FD. These files are copied to an INCLUDE directory by the SETUP program. In real mode (DOS), the programs must be linked with the graphics library GRAPHICS.LIB. In protected mode (OS/2), graphics is not supported, but you can compile text-only programs by linking with the text library GRTEXTP.LIB. The appropriate libraries are copied to your disk by the SETUP program. For example, use the following command line for DOS: FL COLTEXT.FOR GRAPHICS.LIB Or use the following command line for OS/2: FL COLTEXT.FOR GRTEXTP.LIB The programs are listed below: DOS only DOS or OS/2 -------- ----------- Chapter 11 CGA.FOR COLTEXT.FOR COLOR.FOR EGA.FOR GRAPHIC.FOR HORIZON.FOR REALG.FOR SINE.FOR Chapter 12 SAMPLER.FOR Chapter 13 ANIMATE.FOR CURSOR.FOR ARC.FOR MODES.FOR CGAPAL.FOR SCRTXWIN.FOR FIGURE.FOR SETROWS.FOR FILL.FOR TEXT.FOR FONTS.FOR WRAP.FOR MAGNIFY.FOR PAGE.FOR PALETTE.FOR STAR.FOR WINDOW.FOR [...] </cite> Those examples cover many aspects of the system. I only used the Windows part and I believe that under OS/2 there is no graphics, only cursor addressing. The graphics system offers similar capabilities to e.g. Borland's or Quick C's capabilities. regards, Martin

DEC PDP 11 RK05 DEC custom (?) bootstrap board

by billdegnan＠gmail.com

I have what I believe to be two DEC RK05 bootstrap boards each with a ROM labeled 802350 A. UNIBUS. The plastic handle tabs are Digital Equipm.'s but it could be an OEM as there is nothing printed on them. On the board is printed on what would be the bottom front side R-K ABBR BOOT P.C. BOARD 609395 REV B on one line and under that 802000 REV There is a round sticker on the back of the board written in pen that reads: LL 802000 Rev B 6-17-76 printed on the backside of the board near the sticker is 609395 REV B I use a M9312 to bootstrap from the monitor but I am curious how I'd attempt to use one of these. Any thoughts? Bill

Color of Leaky Electrolyic Caps?

by marvin＠west.net

I was just checking out the leaky capacitors on the model 100 motherboard, and they are all colored black. And ditto for the HX-20. The ones that are both light and dark blue look to be fine (no leakage.) So am I just seeing an anomaly, or is this the experience of most people here?

Epson HX-20, TRS-80 Model 100 Capacitor Kits

by marvin＠west.net

Since I have at least four Model 100 and HX-20s, I've decided to just replace all the aluminum electrolytics before repair becomes much more difficult. So far, I see the project as fairly easy depending on how bad the corrosion from the leaking caps is. Is anyone interested in buying a kit or two of the capacitors? I'm guessing buying the parts from DigiKey at low quantity prices will result in about $3.50 or so for the bag of about 13 capacitors. US postage will probably run a couple of dollars or so, but I can also bring them with me to VCFMW. I'll be ordering what I need unless I hear others might want the kits as well. On a similar topic, has anyone given up on cleaning out the corroded plated-Thru-Holes, and just soldered on some SMD caps? If so, how did it work out? Finally, just some observations on the corrosion. I finally found some information about the corrosion caused by leaking aluminum caps. It sounds like the leaking fluid, besides possibly damaging the copper traces, also does something to the solder in the PTH such that a soldering iron won't melt the solder. Right now, the solder doesn't want to melt so I will use a pin vise and about a number 62 drill or so to hand drill out the PTH solder.

Strange third party board in PDP-11/45

by jnc＠mercury.lcs.mit.edu

> As to what _else_ it is doing, and why it has the cable to the main > card... I think that it must intercept MSYN from the processor and only > let it pass if there's no hit in the cache. > (To explain why it would need to do that... normally with the MS11, > there's a static partitioning between FastBus memory and UNIBUS A > memory. So when the CPU goes to do a memory cycle, it can put the > address out on both the UNIBUS and FastBus, with the certainty that it > will only get a reply on one. So, my guess was wrong there. I had _assumed_ that when doing a memory operation, the CPU started a cycle on both busses, to minimize the delay on the UNIBUS cycle if the MS11 on the FastBus didn't have that location. (I had previously checked, and there is an 'I have that location' signal which the MS11 sends back, making the concept of a cache possible.) Well, no. In the "KB11-A CPU Maintenance Manual" (DEC-11-HKBB-D), section 7.7.1 ("Bus Control Introduction"), it says: If the address applies to a Fastbus device, that device will respond in time to inhibit the UNIBUS MSYN signal (It turns out the KB11-A is very clever; it has to delay for a bit after asserting the address, etc, signals on the UNIBUS, for de-skew, before it can assert MSYN, and during that delay, in parallel, it checks to see if the MS11 has that location.) So my theory about what that double-card does (prevent an MSYN sent to main memory on a cache hit) is apparently wrong. Which leaves the question of what that card _does_ do... The cache _does_ need to have the A and B UNIBUS tied together, so that it can snoop UNIBUS memory cycles (which are on the A UNIBUS) via the B UNIBUS (which is what it has access to on the backplane), _but_ it doesn't need a special card, with i) active logic, and b) a cable back to the main board, to do that - a regular M9200 will do that. The cable back to the main card, and the logic on the two dual-width cards, mean it wants to interfere somehow in the connection between the A and B UNIBUS. But if not the MSYN thing, what else could it be? I have pondered that question, but I can't think of anything. It can't be doing anything with interrupts or DMA, I would think, so no grant interception. So what else could it be? Anyone have any ideas? Noel

Model 100/HX-20 LCD Display Problems

by marvin＠west.net

In getting ready for VCFMW, I started looking at some model 100s and HX-20 notebook computers. Most of them have blank LCD displays, so I figured there might be a common problem. So far, I've found leaky electrolytics on all of them, usually 10 uF, but there are some others with all of them so far associated with the LCD power supplies. The Epsons seem less prone to this than the model 100s, but both have the problem. Has anyone that has done repair work on these computers found the major problem to be leaky capacitors? My gut reaction at this point is to just replace all of the electrolytics. Does this sound like a reasonable longer term approach rather than just replacing the obvious leaky ones?

First 3.5 inch FDD [WAS: RE: Prototype IBM DemiDiskette drive]

by t.gardner＠computer.org

Well it all depends upon what u mean by "first" The Sony drive and cartridge were not compatible in many ways with what became the physical, magnetic and electrical interface standards for the 3.5-inch drive and cartridge. The standards came out of the "Microfloppy Industry Committee" (Google it with quotes) organized by Shugart Corp. Either Shugart or Tandon was the first to ship drives compatible to the standard. Tandon probably did the first such cartridge. The original Sony drive and cartridge died out and Sony didn't come out with a compatible set until well after Shugart and Tandon. The early adopters of the Sony design like HP then changed to the industry standard design.

(The Sony 600RPM drives would require more changes) The SA300 could be dropped into a 5150 (with only issues of mounting brackets (Erector set) and power connector) and were supported by some OEM versions of MS-DOS 2.11. IBM public support of 3.5" began with PC-DOS 3.20.

Datic 2000 / Ampex 844 Documentation ?

by jos.dreesen＠greenmail.ch

Ran into an early CP/M system today, from german company Datic. It is a single-user 8080 system, featuring a delay-line based CRT output and an Ampex 844 fixed platter / removable 14" cartridge driver. Is this simply a Diablo 44 equivalent, as I suspect, or is this a true standalone development from Ampex ? First time I have seen a 14" drive on a CP/M system.... Jos

The 3.3 was used on the Kypro "Robie". My 6.6 media was sent to me by the tech support fellow at Verbatim, just before they closed their Santa Clara operation. I already had the drive. The Drivetec drives were also sold by DTC as their "TeamMate" series of external drive/controller combos. There's a German auction of the TakeTen here: https://tinyurl.com/yax6tjvc You can see that the drive slot is considerably thicker than a normal floppy disk--and it's identified as a "Removable Cartridge Disk Drive". Again, I don't recall ever seeing the cartridges. DTC did a lot of strange things. I first knew them as manufacturing a sheet feeder for the Diablo Hitype printer. I still have a few of their disk controller cards and some SCSI controller engineering documents. --Chuck

DTC TakeTen media?

by cclist＠sydex.com

On the subject of oddball PC media, does anyone out there have media for the DTC "Take Ten" cartridge drive? I've got the drive here, still in original shrink-wrap and packaging, but no media, so I don't have the faintest idea if it still works. As the 5.25" cartridges only held 10MB, I suspect this was a flash-in-the-pan venture. I'd never heard of one back in the day when everyone was using Bernoulli drives. --Chuck

Using M122 keyboards on a PC

You can do some remapping, but F13-F24 will not be available, and some keys will not operate the same as they did on the original keyboard. I have used these to test Wyse (with removable cables), IBM, and a bunch of AT and XT keyboards. They do not work for ADDS keyboards.

Prototype IBM DemiDiskette drive

by schlae＠gmail.com

Yesterday I dug out my prototype IBM DemiDiskette drive and took some photos: https://twitter.com/TubeTimeUS/status/1032066215647166464. It caused a bit of interest on Twitter so I figured some of you here may also like seeing it. I don't really know a whole lot about it other than what my grandfather told me (he worked on the team that developed it). Dates on the remaining paperwork go from December 1979 through August 1980. It was supposed to be a very low cost drive for the microcomputer market (target price IIRC was <$100). Although it was originally developed by a team working at IBM Austin, it was handed off to a different team apparently working out of Rochester. The disk capacity was not very large--I don't remember the exact number but it was probably around 100K or less. A few interesting observations: * The stepper motor uses a spiral cam to convert rotation into linear motion to drive the head. * It is a single-sided drive. * A microswitch senses the presence of the disk instead of an optical pair. * There is no write protect notch or sensor. * There is no index sensor. * The spindle drive motor is a DC brushed motor with an encoder wheel for speed control. * Not shown in the pics, but the plastic "spot welds" holding the vinyl jackets on the disks are intentionally widely spaced making the cookie easier to remove for analysis. It's not really something you get to see every day, that's for sure... --Eric

RK05 spindle pulleys - trade 50Hz vs 60Hz?

Why don't you simply power it through an inverter that will output 60 Hz, eventually even "down to" 120 V , true sine wave, of course ??? They are not that expensive by now. And be carefull : motor designed for 60 Hz, running "under" 50 Hz, OR THE OPPOSITE, I do not recall !!!, display a significant reduced life time. I have to check which is which, but I know this is a question of saturated magnetic field. Better check first.

I'm sure it's been years since I've darkened anyone's door around here. I still have this idea that someone should write a proper BBS system (and run it) for RSTS... ...the age old problem is getting data in and out of it to connect it to the world... or one of the problems anyhow. Maybe using a telnet connection to a terminal device and some sort of homebrew message queueing system to an outside helper. Hmmm.

How to tell if a Displaywriter 6360 floppy has double-sided drives in it.

I don't know if this is always true, but it appears that the way you can tell is if there is a "T" on the lower right of the 6580 badge on the front. I didn't see this in the documentation anywhere. The controller inside is significantly different (3 boards instead of one). +--------+ | IBM | | | | 6360 | | T| +--------+ There are a couple up on eBay right now from seller 'potomacestore' Double-sided 6360s seem to be much less common than single-sided.

VCFMW 13: Less Than a Month to Go!

by silent700＠gmail.com

Hello classic computing fans! We're entering the final weeks before the big event, and here is an update. If you're subscribed to the mailing list, you've already seen most of this (for review/sharing: https://mailchi.mp/e060dcbd1bfd/vcf-midwest-13-one-month-to-go). - Exhibits: Our exhibitor list has been posted, showing most (but not all!) of the displays you'll see this year. We're happy to once again have a great variety of platforms and eras represented, as well as some new faces alongside our veteran exhibitors. Check it out at: http://vcfmw.org/ex.html - Table space: We are full! Until, that is, we're not. All of the past shows have included several last-minute changes, so space does open up. There is a stand-by list forming; please email me directly if you'd like to be on it. - Presentations: Once again this year we have a full weekend of interesting talks and demos. The schedule (as it stands now) has been posted. All talks are filmed and will be posted online - but they're always much better in person! http://vcfmw.org/pres.html - Hotel: Due to other parties pre-booking a large block of rooms, Friday night (14th) at the Holiday Inn is sold out. If you have not yet reserved a room, please check back with the hotel after 8/27, as any remaining unbooked rooms will be added back to our block on that date. Our block still has rooms for Thursday, Saturday and Sunday nights. - Donations: VCFMW is a community-supported exhibition, free and open to all. Most of our funding comes from either cash donations (online or at the show) or donations of equipment for our community auction. Please consider one or both methods of support. Auction items can be given to VCFMW staff before Saturday afternoon. Purchasing items at the auction also helps - and it's always an event not to be missed! - Free pile: The tradition of the Free Pile continues this year. This is a great way to unload that "junk" (but not too junky) hardware and software and contribute to the classic computing community. Our only request is that you make sure that whatever you leave is gone by 4pm Sunday. We thank you once again for your interest in and support of VCF Midwest and the whole classic computing hobby. We'll see you in a month! -j

Fairly Extensive Singer/Friden "System Ten" Computer System for Rescue

by rickb＠bensene.com

Through my Old Calculator Museum website, I have been contacted by a gentleman that has a fairly substantial Singer/Friden System 10 that is located in a building that the business wants to clear out. The computer system is slated to end up in a dumpster if it isn't rescued. The place the machine was stored is indoors, in an office-like space in a larger warehouse style building. The space was not temperature controlled, but there are no signs of water damage or serious corrosion. Some critters (probably mice) have been inside the cabinets of the system, but the contact said that there were no obvious signs that they chewed anything up. The system is very dusty (it was not covered), and it appears that some panels on the cabinets may have been removed, but are probably with the system. Some stuff appears to be partly disassembled. There also might be some spare parts, e.g., circuit boards. The system consists of a CPU, probably a Model 20, two Model 80 Display Terminals, a line printer of some sort, and two Mode 40 disk-pack (aka dishwasher-sized) disk drives. There are quite a few Model 41 disk packs there.. There also appears to be some documentation. There may also be some kind of magtape drive with the system, as there is a rack full of 7 or 9-track tapes hanging in it. Not sure if these are included with the system, though. Here is a link to some photos of the system: http://pail.bensene.com/Singer10 Beware that the web host does not have much upstream bandwidth, and the photos are pretty high resolution, so downloading them may take some time. Most of the photos are between 1.8 and 2.5 megabytes in size. there is some documentation on the Singer System Ten up on Bitsavers at http://bitsavers.org/pdf/singer/systemTen . Some of the documentation there is for the equipment that is available. These systems aren't very common, and there likely aren't all that many of them left in existence. Singer sold a lot of these systems into retail outlets as part of one of the first online Point-of-Sale systems. One notable account was Sears and Roebuck, who installed a huge networked (via Modem) environment using System Ten machines in stores to run Point-of-Sale systems, with modem links to larger systems that collected the information, and usually fed it to even larger systems (e.g., IBM mainframe) for inventory management, bookkeeping, and other large corporate-level reporting/management systems. However, the system aged quickly, as other competitors came onto the Point-of-Sale scene very quickly, with systems that were less expensive, more reliable, and more easily maintained. Many of the Singer systems in large retailers were replaced within a few years of being put into service. There was little market for "used" systems, so most all of them taken out of service went for scrap. The System 10 CPU was pretty unique in that it had "hardware"-based timesharing. The system managed time-slicing between "partitions" in main memory (magnetic core) with hardware that provided a fixed timeslice to each partition, switching to the next either when the time-slice ran out, or certain instructions (e.g., I/O) were executed that would trigger an immediate context switch. The system had hardware protection for the partitions to isolate the partitions from each other, allowing them to run independently. There was a shared and a read-only system partition which could facilitate inter-partition communications and management functions. Pretty cool for a design done in the late '60's. It'd be a real shame for this system to end up in the trash, which is exactly where it will go if a home can't be found for it relatively soon (e.g., next couple of weeks). The system is located in West Chicago, IL. It's all pretty sizable, so, you'd probably need a small commercial-style moving van with a lift-gate (the stuff is likely quite heavy, especially the disk drives) to haul it. You would also probably need a heavy-duty hand-truck or two, and some strong straps. You'd need some muscle, too. I suspect it'd be more than a 1-man job. My contact wants it out of there. You just have to come get it and haul it away. If you have any serious interest in rescuing this system, drop me an Email, and I'll put you in touch with my contact. Hopefully someone out there can give this machine a new home. Email: rickb .at. bensene .dot. com Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

VCFMW drop offs, pick ups, visits

by useddec＠gmail.com

I'm looking forward to seeing everyone going to VCFMW. I'm going to try to go up Friday and leave late Saturday. It's always great when people swing by the house, but try to give me some warning, especially with me going up Friday. I hope to have a path dug into my last 25 foot storage unit and retrieve a ton of micro-Vax II parts along with a ton of other items. I still have a few 3000 alphas, about 10 3100s, a few 4000s, 5000s, 6 or so BA11-N (11/03L/23) boxes, BA23s, LA120s, and 1000's of other parts. Also some REMEX interfaces and a bunch of paper tape readers and maybe punches I'm getting tired of looking at. Please contact me off list if you have any requests or questions. Feel free to send me wish lists. Thanks, Paul

VCF Midwest seller's experience?

by marvin＠west.net

This will make my third year selling at VCFMW. My motives are to pay for the trip :), Diminish the "collection", and have fun talking/meeting with other attendees. All three have been easily accomplished! For me, I don't relish the use of a consignment area and spend most of my time in the selling area. I try not to buy much as I am really trying to downsize the collection. I do find it better to try and have buyers waiting for anything large or heavy. I'm not sure, but I suspect enough people might be interested that it could be a 24 hour event, Fri night - Sun afternoon :). See you there!

VCF Midwest seller's experience?

by jfoust＠threedee.com

I'm thinking of reducing my collection by bringing items to VCF Midwest. I attended once six or seven years ago. Of course a great deal depends on what I'm selling, so I'll build a list. Possibles include Micro PDP-11, Microvax II, Vaxstations, Kaypro 1, CBM, Amiga, Atari, Apple, some S-100 boards. Is there anyone here who sold at a previous VCF Midwest? How did it go? If there's only 150 attendees, is selling more like exhibiting? Ideally I'd like to come home with an empty van. - John

Single-height Qbus grant continuity PCB

by ard.p850ug1＠gmail.com

All the PDP11 people here will know the little square grant continuity board used in Unibus machines, along with the later dual-height one that also connected the NPG signal. And the common Qbus grant continuity board that was also a full dual-height one that had a couple of pairs of pins linked on one of the connectors. But I have here a little square board (the same size as the older Unibus grant continuity card) with just 2 pairs of pins linked. In the etch is a Digital logo (so I assume it's a real DEC product) and : LSI11 Grant Continuity G7272 5012564B Side 2 Has anyone come across that one before? -tony

Help ID'ing Bridge Rectifier

by derschjo＠gmail.com

Hey all -- Working on bringing a Dasher D200 terminal back to life. There's a bridge rectifier package that appears to have a short in it and I can't find any info on it -- I suspect it may have a house part number. It's got a Motorola logo on it, and is labeled "SDA314." In the schematic ( http://bitsavers.org/pdf/dg/terminals/014-000640_DASHER_D100_D200_Display_T…) it's CR6. This short causes the 5W resistors before the fuse to smoke and explode, but the fuse is fine (thank goodness.) :). Anyone have any ideas? Thanks, Josh
