VT220 keyboard (cont'd)

by charlesmorris800＠centurytel.net

Thanks for the replies, all, especially Tony Duell who had it spot-on: >This normally means there's a short in the keyboard matrix, as if one key >is stuck down. > >What I would do is open up the keyboard casing (there are 2 screws under >the plastic posts/feet) and remove the internals. (snip) >Connect the PCB to the terminal with the normal cable and power up. Most >likely the LEDs will go through the normal sequence and there'll be no >error message, which shows the fault is in the keyboard itself. The LED's do indeed cycle when the isolated PCB is hooked up, and eventually "VT220 OK" appears on the screen. So now I either have to find the shorted key (it's pretty dirty in there so blowing with compressed air might help) or just get another keyboard. I won't try and wash it after reading the warnings here. BTW I see one on ebag right now (190254818657) but it's a "VT220-Style" unit, made by another manufacturer. Think it'd work with a real VT220? thanks Charles

Help with PDP-11 Unibus Map Hardware / Software under RT-11

by jhfinedp3k＠compsys.to

Hopefully, this request is clear enough to be understood. Both the software and the hardware portion of the questions are independently important, so please answer one aspect even if you can't help with the other. Over the past 30 years of using PDP-11 software (RT-11 over 95%) and hardware, I have never had occasion to use a Unibus system with more than 256 KB of memory (such as a PDP-11/34). I would appreciate help in understanding the Unibus Map hardware which (if I understand its purpose correctly) is to convert 18 bit addresses given to a Unibus controller into 22 bit addresses for real physical memory for systems like a PDP-11/84 and perform DMA from / to the hard drive. Also helpful would be an explanation of the related software used under RT-11 along with exactly where the Unibus Map hardware is located on a real DEC system (on the CPU board I presume) since the identical CPU board is used for both the Qbus and the Unibus with both the PDP-11/84 and the PDP-11/94. ------------------------------------------------------------------------- DO NOT READ THE FOLLOWING if you don't use RT-11!!!!!!! By way of context, I have successfully modified the HD0: device driver originally written by John Wilson which obviously executes ONLY under E11. Last week, John mentioned in a private e-mail that it is possible to direct the HD0: "controller" (all references to hardware in quotes refers to E11 software) to ignore the "Unibus Map hardware". Since I execute under E11 using Qbus emulation in order to stay totally compatible with the real DEC PDP-11/23, PDP-11/73 and PDP-11/83 systems (all Qbus and all with 4 MB of physical memory) which I have available for comparison testing, user buffers in physical memory above 256 KB are often a situation which can't be avoided. Consequently, it had always been a high priority to have a 22 bit device driver for HD0: under E11 BECAUSE HD0: is TWICE as fast as MSCP (DUX.SYS device driver). In addition, I have also been able to write code that avoids the overhead of using the HD0: device driver which makes HD0: FOUR times as fast as MSCP and also allows for direct access of 2 TB of disk space via a 32 bit block number. Since I have an immediate application for a data base of 32 GB (I have a disk drive of 160 GB, so 32 GB is only 20% of its capacity - although under RT-11 15 years ago in 1992, 32 GB would have been only a dream), the code which I have written will actually be used quite soon. However, I would very much like the HD0: device driver to be able to execute under both "Qbus" and "Unibus" hardware. And while I can test the code for a "Qbus" and for a "Unibus" without a "Unibus Map", I am not clear about what is required for a "Unibus" with a "Unibus Map" such as a PDP-11/84 running under RT-11. Megan are you still watching the list? Allison, if you can't answer, can anyone but Megan help? Is anyone else familiar enough with the "Unibus Map" that you can suggest what RT-11 actually needs to do with the "Unibus Map"? A solution is to check the "hardware" configuration and refuse to allow the HD0: device driver to LOAD or .Fetch if the modified version is not executing under "Qbus hardware". By the way, if anyone who is thinking of a controller for the Qbus which is able to use SATA drives, I would be happy to modify an RT-11 device driver to an HD0: type device that is able to handle drives up to 2 TB in the same manner that DU(X).SYS can handle drives up to 8 GB. Anyone interested?? Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

Making an RT-11 boot disk

I'm trying to use simh to create an RT-11 bootable RX50 disk and am following some instructions posted by Megan Gentry a while ago.

HP 9000/300 computers available

by devilanse＠gmail.com

Hello, The company I work for has approximately 15 HP 9000/300 computers available. These are mainly the 310 models. There are a couple of other models too. Most of them have the SRM boards installed. There is also a HP9826 available. Also are keyboards and monitors. There are NO hard drives or floppy drives. We are going to do an renovation of the area they are stored in. They are free for local pick up in Lexington KY or if you arrange for freight pickup, we will put them on a pallet and wrap them. If there are no takers in 30 days, they will be scrapped. thanks Max

VT220 Keyboard Error 4?

by tiggerlasv＠aim.com

I tend to look for the simpler explanations first. If your keyboard was previously working, the first place I would check is the MMJ on the back of the terminal. I've seen everything from malformed pins, to corrosion, to spider webs, to dead bugs inside RJ12 / RJ45 connectors. Another point of failure is the?MMJ on the keyboard cable; you can try removing that, and re-crimping it. T

Z80 home brew with FDC

by lynchaj＠yahoo.com

________________________________ Yo, Tony here (Sharkonwheels on VC) Got any boards left? CPU board, ECB backplane, and (if ready) FDD/IDE board. Tony [snip] -----REPLY----- Hi Tony! Thanks! Yes, I have several PCBs left. I have N8VEM SBCs, ECB backplanes, and ECB bus monitor PCBs. I just received the ECB bus monitor PCBs and haven't finished building mine yet. Some of the other builders are helping out by taking the lead on the first ECB bus monitor for build and test phase while I continue work on the Disk IO board. The ECB backplanes are going fast which rather surprises me. I have only a few left and am going to have to reorder. The builders who have ECB backplanes seem to like them though. The Disk IO prototype is working fine so I am writing up the schematic and doing the PCB layout right now. I'll be posting the schematic and PCB layout for some much appreciated peer review in the next few days. I am still doing quality checking on them to make sure they are right. The IDE portion looks OK but the FDC portion is complex and has me concerned. The big difference between the prototype and the manufactured PCB will be several option jumpers and a "feature" connector to help builders who want 8" drive support. Thanks and have a nice day! Please contact me offline if you'd like some PCBs. They are still $20 each plus shipping. Andrew Lynch

Searching for Manual - Hazeltine 1410 Terminal

by ragooman＠comcast.net

Would anyone have a service manual for the Hazeltine 1410 terminal ? I have a peculiar problem where several keys output a different character. I found there's a pattern to this chaos. From looking at the ascii data, bits 5 and 6 become swapped only for characters between 40h and 5Fh. instead of an 'A' it displays a '!" and it continues like this. I'm afraid the i8243 chip might be bad but I'm not completely sure. I found the i8243 datasheet and currently trying to trace the connections. I hear this chip is hard to come by. I only found one supplier so far which I'm waiting to hear back on the rfq. thanks =Dan -- [ Pittsburgh 250th --- http://www2.applegate.org/~ragooman/ ]

Not quite. I don't recall the details of the difference, but I think it may have just been the polarity of one of the signals. The 9229 and 9239 had a configuration input to select between 179x and 765 modes. The 9216 would directly connect to one, and needed a small amount of logic (maybe just an inverter) for the other. > The decoder is made up of a 74LS197 (clock divider), a dual 74LS74 flip-flop, > both used, a 74LS163 counter and an inverter.

Sure, but it doesn't sound like it's a very good data separator. The good ones have a PLL (either analog or digital), because it is necessary to track speed variations, not just of the drive that you're using to read a disk, but also of the drive that wrote it. Non-PLL data separators work OK when the disk is both written and read under optimal conditions, but are unreliable otherwise. The 9216, 9229 or 9239 are *highly* recommended, as they have a good digital data separator. The 9229 and 9239 also contain write precomp logic. The 9239 uses higher resolution timing for its PLL, so it may perform better. ------REPLY------ Hi, Eric is right about the FDC9229 being mode selectable between 179x and 765 modes. It makes a difference in a number of output frequencies, etc. Check the datasheet. It is at the bitsavers.org URL I posted previously. I can't speak to the PLL issue but Eric is consistent with what I have read and heard previously. You can make data separator replacements from TTL but the FDC9229 data separators are really good and provide more than just data separation. They do a whole host of functions such as FDC clock, data window, variable write precompensation, etc. I recommend them and they are fairly easy to work with. They are not easy to find but they are available if you look enough. Is anyone interested in adding a 765 based FDC to their Z80 home brew computer? This design is mostly done and just needs some road testing and another set of eyes to check it out. The software is kind of crude but working. There are only a couple of modifications left on the hardware. First is to attach the FDC9229 write precompensation pins to the latch and second is to connect the remaining two latch pins to FDC interface pin 2 and 34. The hardware will probably get finished this week some time. The software will probably take a while though. Tonight I read and wrote sectors on the IBM PC 360K 5.25" floppy disk. On the same disk, I formatted some tracks so these functions seem to be working in both DD and HD mode. Also verified with Catweasel that the 1.4M 3.5" floppy disk is generating correct tracks. All the sector header information is checking out right it seems. BTW, when working on this FDC project, I cannot say enough good things about the Catweasel. It is like have having x-ray vision into what is being written to the disk and shows all sorts of hidden stuff. Very helpful when you can check independently what the i8272 is doing compared to what it will tell you it is doing. Thanks! Andrew Lynch

boards

by rtellason＠verizon.net

In going through my stuff I've come across some boards that may be of interest. I've uploaded some pictures here: http://mysite.verizon.net/rtellason/pa020085.jpg I'm not sure what this is. The big ceramic cased device is an 8x300 series part, maybe 8x305? I can double-check that if anyone's interested. The rest of the board is generic TTL mostly. http://mysite.verizon.net/rtellason/pa020086.jpg http//mysite.verizon.net/rtellason/pa020087.jpg This one I have no idea about, most of the 14/16-pin parts are generic 4000-series CMOS and the 8-pin parts appear to be linear chips, op amps and such. The second pic is the panel on the left side of the first pic. Then there's this one: http://mysite.verizon.net/rtellason/pa020088.jpg ...a PMMI modem! I remember seeing that referenced a whole lot when I was hacking away at CP/M comm programs, that seemed to be included in a bunch of them. Anybody interested in taking any of this stuff off my hands, feel free to contact me offlist. On that last one in particular, I'd like to get somewhat more than shipping costs. :-) -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

LED displays (TIL305, TIL308, etc.)

by ethan.dicks＠usap.gov

Hi, All, Since one of the first computers I ever got my hands on as a kid (Quest Elf) happened to have TIL311 HEX displays, I've long been fascinated with display technology of that vintage. I was poking around for images of some of the related displays to the TIL311 and ran across a couple of links with pictures and some history... http://www.decodesystems.com/old-displays.html http://www.decadecounter.com/vta/tubepage.php?item=33 In particular, I notice that one of the displays I have one of is a TIL305 or MAN2 (no logo on mine). I was also looking at the TIL306 or TIL308, but don't happen to have any of those. I do have a reasonable quantity of TIL311s for my various Elf and Elf2000 machines and even a set that came with an INS8073 SBC. I would love to find a couple more TIL305s so I can round out an old project, plus I had an idea for a project that would be interesting to use TIL306s or TIL308s (don't care about where the decimal point is, so either is acceptable), but ISTR some discussion on the list a while back about those in particular, possibly as replacements to some HP counter, and how difficult and expensive they are to obtain. TIL311s are frequently found on eBay for various prices; I've gotten them myself for as little as $2.50 each in small quantities. I doubt that TIL306s and TIL308s are anywhere near that inexpensive, no matter what the quantity, but I thought I'd ask if anyone has recently found any place selling them. I'm not trying to repair a bit of vintage kit, so I'm not willing to pay "any" price for them - if they are too expensive (as I suspect they are), then I will find some other display. Yes, non-driven LEDs are inexpensive to free and modern microcontrollers can drive wads of LEDs easily and cheaply, but what I'm going for is a 1970s look with 1970s components (i.e., popcorn-logic driven, not micro- processor-driven). The advantage of the TIL306s and TIL308s is now what it was then - a high level of integration reducing the overall wiring complexity and parts count. The disadvantage now as then is that the displays are more expensive than the entire rest of the device. They still look cool, though, and that's the real point. -ethan -- Ethan Dicks, A-333-S Current South Pole Weather at 29-Sep-2008 at 22:20 Z South Pole Station PSC 468 Box 400 Temp -71.3 F (-57.4 C) Windchill -102.3 F (-74.6 C) APO AP 96598 Wind 7.6 kts Grid 72 Barometer 683.5 mb (10496 ft) Ethan.Dicks at usap.gov http://penguincentral.com/penguincentral.html

Century Data Systems T-50 disks

by d.panicacci＠sbcglobal.net

Patrick, It was in the late 70's that I was a young technician on the test line at Century Data Systems in Anahiem CA, I remember when the Trident line first got started (T25, T50, T80) they were the latest in high technology, I was one of the first techs to work on them. These disk drives were built to last, I beleive I have some of the old "theory of operation manuals" for them. Thanks for the memories. Do you have a web page with pictures? I also worked on some of the first disk drives that Century Data made back then, I had 18 years in with them untill 1988 just befor they went bankrupt, at lest that is what we were told. Dave

help (re) booting xenix after cmos battery failure

by brad＠heeltoe.com

A friend of a friend has an old xenix machine; Compaq DeskPro 386 running Xenix. He shut if off after running for years and it won't boot because the cmos battery is dead. The disk is an ESDI drive attached to a Compaq ESDI/FLPY controller (copyright 1989) ISA bus card. He says can't see any way to enter a "setup" mode in the BIOS. Anyone know how to fix this? apparently it has his Alfa Romeo motor club data on it (so it's clearly +10yo :-) Anyone know if the xenix fs can be mounted on linux?

HP 5036A microprocessor lab - searching for copy of "Practical Microprocessors"

by hpjimbondoris123＠dorisland.net

Phil: If you download the manual you will see that it is in color and was scanned at 300 dpi color. I believe that HP did this on purpose so that you could not copy it on a copy machine but rather contact them and purchase another copy. On the rom listing I had to even play with the contrast and brightness just to get it to be read. Please if you want take a crack in reducing the file. As I spent the entire day just on the 40 pages it was the best I could do to get out the document for those folks whom have the trainer without the manual when it came to the schematics those were scanned in black and white as they are black and white.

So happens one of my "small" pdp-11s uses a Tu58. the system is a BA-11V with an 11/23 256k of ram, DLV11J and MRV11 rom(boot). Takes 10 minutes to boot, setup VM: then copy key files to and reboot. After that it's pretty decent even if I have to access a file on tape. Everytime I runs it with a bunch of kids of the current PC generations they go gaga and comment on how slow then I explain the amount of ram and storage then they are amazed it can be a functional machine with so little. They can't imagine a useful machine with 32kW of ram and 256kb of storage. On the flip side I've used that same Tu58 to bring up iron that had no removable storage. It's slow but very dependable.

Looking for Norsk Data ND-100 info.

by axelsson＠acc.umu.se

Hi! I'm looking for ND-100 information. A couple of my friends have started to work on a ND-100 emulator and it is progressing fast... fast to a point where we are lacking information about the inner workings of the ND-100 CPU. Specifically we are looking for information on the real time clock interrupt and micro code programming but other information (manuals, schematics or programs) is also interesting. I currently have the following manuals that I'm transforming into pdf:s as time permits. * ND-06.007 BIG MULTIPORT MEMORY SYSTEM * ND-06.014 ND-100 REFERENCE MANUAL * ND-06.016 ND-100 INPUT/OUTPUT SYSTEM * ND-30.003.06A : SINTRAN III System Supervisor * ND-30.025.02 : COSMOS Operator Guide * ND-30.071.1 EN : ND-5000 Series User Guide * ND-40.004.06 : Norsk Data Documentation Catalogue * ND-40.012.1 EN : Information Pamphlet for Norsk Data Customers * ND-60.014.01 : Page III-1-1 to A-9 (some pages missing) * ND-60.046 TRACE ROUTINE * ND-60.047.03A : NORD PL User's Guide * ND-60.050.06 : SINTRAN III Users Guide * ND-60.066.04 : ND Relocating Loader * ND-60.074.01 : NORD-10 FORTRAN SYSTEM Reference Manual * ND-60.088.03 : ND Screen Handling System * ND-60.096.01 : Page 2-16 to D-3 * ND-60.111.03 : ND TPS User's Guide * ND-60.132.03 : SINTRAN III Timesharing/Batch Guide * ND-60.151.02A : SINTRAN III Utilities Manual * ND-60.158.3 EN : SYMBOLIC DEBUGGER User Guide (2 ex) * ND-60.163.4 EN : COSMOS User Guide * ND-60.196.01 : BRF-LINKER User Manual * ND-60.230.01 : SINTRAN III J-version Release Informaton * ND-60.236.1 EN : ND-100/500 SORT-MERGE User Guide * ND-60.264.1 EN : SINTRAN III User Guide * ND-63.001.02 : Introduction to NOTIS-WP * ND-63.026.02 : NOTIS-CALC Handbok (in Swedish) * ND-63.042.1 EN : NOTIS-WP M Release Information for new users * ND Ring binder with cable diagrams * Am201B/Am2901C Four-Bit Bipolar Microprocessor Slice, AMD. Page 5-1 to 5-18 * PASCAL : Instructions in Swedish for running Pascal on ND-100 If you have anything outside of this list please let me know. I will borrow for scanning, buy or trade anything of interest. The hardware we got access to is a ND-100 satellite, two ND-100 racks with disks and 8 inch floppys in parts and a nonfunctional NORD-10 in a rack. When time permits we will try to get it running. /G?ran

Two more Craters & Freighters happy experiences

by legalize＠xmission.com

I recently had two more items packed and delivered to me by Craters & Freighters. Holy shit, what a difference it makes with that company. A Tektronix 4170 local graphics processor and an Evans & Sutherland PS 390 base unit arrived with no scratches, no falling apart pallets and everything intact. The tally so far: + seller freight packed deskside SGI Onyx + C&F packed lot from dovebid (Tektronix graphics terminals) + C&F packed Megatek graphics terminal + C&F packed E&S PS390 + C&F packed Tektronix 4170 - CTS packed deskside SGI Onyx & Octanes - adcom worldwide packed SGI Octanes, O2s and monitors In the case of CTS/adcom worldwide, the only reason that I used them and not C&F is that there wasn't a C&F that could go to Reading, PA and pick up the stuff from a dovebid auction. C&F may not be the cheapest; to be honest, when C&F service is available I don't even bother to check with other freight shipping service companies. However, what good does it do you to save a few dollars on shipping and have something arrive smashed or cosmetically ruined because of poor packing? I heartily recommend Craters & Freighters for your packing and freight shipping needs. <http://www.cratersandfreighters.com> -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

SS10s and SS20s free for local pickup or $10 + actual ship

by rescue＠hawkmountain.net

I have 3 SS20s and 4 SS10s. Mostly complete. All have one or more processors (ranging from SM41 to SM61), I believe all have RAM, and some have one or more drives. No GFX as these were last used for servers. These are free for pickup in Sharon, MA 02067, or I can bring them with me to work in Cambridge, MA 02140 (on the same road as Alewife T station). If you want one shipped... $10 + actual ship with the $10 to cover the materials/time to pack and haul to PO/FedEx/UPS/etc. If these don't move before that dumpster leaves here (1-2 weeks >from Friday), then I'll pull the CPUs, RAM, and drives, and heave them into the dumpster. The SS20s are all Aurora I chasis. I don't recall any having CD rom drives... one or two fo the might have floppy drives. -- Curt

VT220 Keyboard Error 4?

by charlesmorris800＠centurytel.net

I turned on my VT220 for the first time in nearly a year. The screen says "VT220 Keyboard Error 4", all four green LED's (on the top right of the keyboard) stay lit, and nothing appears on the screen when I type. Disconnecting and reconnecting the coiled-cord between the keyboard and the terminal causes a cursor block to appear on the screen, but the keyboard is still locked and the LEDs stay on. Power-cycling the terminal shows the same error message. However, the boot prompts from the 11/23+ are displayed normally, so the receive part of the terminal at least is working. Where should I start looking, before replacing the keyboard? thanks for any hints -Charles

Need Tecmar JrCaptain power supply specs

Hello everyone, My JrCaptain and its power supply (the wall wart) have become separated. I'm pretty sure I still have it, it's just that I don't know which one it is. Naturally none have the Tecmar name. I'm sure someone here has one of these, so would you please look at the wall wart or power brick and tell me what it says? Thanks, Jim

anyone utilizing early Macs to access the internet?

by mc＠media.mit.edu

> I've been told using the compact Macs are an exercise in futility. > But what about the Mac II's? (original II, IIx, IIfx, IIcx). > > I was just curious. Right. For a pre-Mac II (e.g. Mac Plus), even Appletalk network file sharing was an exercise in futility, let alone Ethernet. Until the Quadras came along, an Ethernet interface was not built-in. You had to buy a separate network card for you Mac II, and more likely than not, it used "thin ethernet" (coax) not 10-base-T. I did use some 10- base-T SCSI Ethernet adapters for non-expandable Mac laptops around 1975, but they were barely up-to-snuff. While I was in grad school, from 1997 through 1999, I used a Quadra 700 running IE for browsing the web. It seemed unbearably slow even then, and I think I switched to Netscape because its rendering engine was more efficient (IE often had to redraw the whole web page twice-- e.g. to figure out how big the images were, and on a 68040 that was a noticeable delay). Plus a lots of things have changed since then. I don't think I even needed a Flash plugins at the time. Not that you would even think of watching a YouTube video on a processor that slow. For email I used GNU emacs RMAIL running on my group's Unix server. I had to abandon it when MIME became the norm around 2000. Bottom line: For small values of "access the internet" the older Macs were serviceable. By modern standards, the old browsers are curiosities at best. But if you need to transfer some old files off your old Mac, the connectivity is there, and I have been grateful that FTP still works even today. --Tim

HP 5036A microprocessor lab - searching for copy of "Practical Microprocessors"

Hello group: I have a person whom was kind enough to post the PDF excerps from scanning "Practical Microprocessors" which is the lab manual for the HP 5036 microprocessor trainer.. I scanned the schematics, rom listing and a few other pages. You can find it on Dave's site here http://www.neurotica.com/misc/practical_microprocessors.pdf be warned that in order to make it worth while to read its 125 megs I suggest that you print it out the 40 so pages. I printed it to make sure that its readable. Spent a day to scan it and build the pdf so I hope those with the trainer and have no manual will find it usefull. Jim

Hi, Thanks for the encouraging responses, I'll go and have a read. Someone also kindly emailed me these URLs with further useful info: http://www.pimpworks.org/ibm/aixled.html http://www.pimpworks.org/ibm/ledcomm.txt I have contact with a AIX CD, and I have obtained (a few!) SCSI CD drive that cn be tweaked to the correct sector size. Couple more questions though: 1. Is there a back-up battery (perhaps in a RTC chip like on a Sparcstation 2), that will have surely failed by 2008. 2. Is there a source to download diagnostic floppy set, I hadn't known about these until today.

If you look for "bezel" in electronics catalogs you'll see both grey and red filters... but that's a good way to pay a lot of money for ten cents of plexiglass :-). The Rohm-Haas color code for the red transluscent plexiglass you want is #2423, it's fairly common at real plastics supply houses. Now finding good plastics retail shops that'll sell or even give away small scraps today is not as easy as 20 years ago... a 4x8 sheet of this stuff is pretty huge for TIL305's!

It thrived in England in the early 80?s: The very first example of this 'computer encoding' on vinyl that I'm aware of is on Isao Tomita's "The Planets" (1976) album of the Gustav Holst piece done up with various -- new at the time -- synthesizers. When I first heard this in 1977 I was just getting my fingers into computing, but had no way to decode the message. According to my memory, the liner notes specify that it is played into a certain cassette I/O interface on an Altair 8800 (or was it Imsai 8080?) one would find a special message. I never had the hardware for that, nor have I thought much about it over the years. I'm going to have to dig that album out (yes, I still have all of my old vinyl!) and confirm the target system, and then see what can be done to decode it with today's tools. Hmmm.....yet another project on the list! - Jared PS. If anyone is more determined than I am, let me know and I'll create a .WAV file of the section in question for your enjoyment.

IBM RS/6000 Help / advice wanted

by john_a_s2004＠hotmail.com

Hi, Last year I bought an RS/6000 Model 34H as I wanted a cheap example of an old Unix/AIX workstation. Having sorted out a monitor (with 3W3 lead) the machine appears to be faulty. So far whenever I power it up, I see: - a series of numbers on the front LED display (got them listed on a piece of paper somewhere, sorry not got it to hand). - Nothing on the monitor - No activity on either of the 2 serial ports (using an RS232 break-out box to a PC running terminal emulator) The machine didn't come with a manual, looking on the net I haven't found a source to buy a suitable manual let alone download one. Currently the machine is sitting out of the way doing nothing, I would like to see what the problem is before deciding whether to scrap it or try and repair it (assuming it is something like a failed SCSI hard drive). Can anyone advise what to try, or a list of what the LED numbers mean? Should for example the external SCSI connector have a terminator? I think next time I buy an RS/6000, I will look for one that comes with a manual!

power supplies offered

by rtellason＠verizon.net

I have a couple of power supplies, condition unknown, that I believe are for some early Zenith Data Systems machine. There is some slight marking on them saying "ZDS 234-999" and that's it. The connector is the molex-type and not your typical PC type PS connector. Are these worth anything to anybody? Or should I just scrap 'em out? -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

The Crossbar System That Controlled MIT Trains

(The one in Sacramento CA comes to mind: www.smrhs.com) s shumaker I don't remember it being modular enough for shipping by UPS. Just to give you a sense of scale... The train control system measures approximately 8'w x 6'h x 1'd. and weighs at least one or two hundred pounds. My estimates are all from memory, but I have absolutely no doubt that it would have to be shipped by truck unless it was disassembled (that would mean, sadly, cutting wires). It would fit in a big cargo van or a small U-Haul. Someone with lots of space in their basement (not already taken up by trains) and a passion both for telephone technology and trains is the best candidate. --Tim

OT? HPCC mini-conference photos

by ard＠p850ug1.demon.co.uk

The reason this is OT-ish is that HPCC is not a classic computer organisation. But at the mini-conference each year it's become something of a tradition for yours truely to dismantle some strange piece of HP computer hardware, almost always over 10 years old Anyway, there are some pictures of this year's event on http://www.voidware.com/ In case any of you care what I look like, I'm the 'high mass hobbyist' in some of the pictures. In particular in the first picture (also on the homepage IIRC) I'm the person holding up a length of paper tape. Other photos are probably of more interest. This year I dismantled an HP2748A paper tape reader. There are some pictures of the chassis and at least 2 of the PCBs. Also a picture of some of my classic HPs, including a 9830 which I used to demonstrate the reader. The laptop thing is an HP PortablePlus. You see I needed to show the program listings and program output to the audience and the HP9830 display is not ideal for this. So I stuck the 11205 serial interface module in and linked that to the PortablePlus running a terminal emulator. Now I have the somewhat rare compositie video output module for the PortablePlus, the output of that I pluggged into a borrowed, modern, video projector. -tony

stuff for free/donation/trade -> cheap

by rescue＠hawkmountain.net

I'm having some roofing work done... and a dumpster is coming in.... I'm going to use the opportunity to unload (with great reluctance). I have SS10, SS20 stuff, Mac stuff, PC stuff (some systems, some 'bases' (i.e. SS10 nds cpu, graphics, ram), lots of parts). Way too much to list. Most stuff will be free (donations or trades appreciated but not necessary). If there is anything Sun (ss1 through SS20 era), Mac (68K era with some pre G3 PPC stuff too), SGI (Indy, I2 stuff), PC (286->P3 era including CPUs, mobos, cases, power supplies, ISA cards, VLB cards, early PCI stuff, smaller drives, controllers, etc).... that people are looking for... let me know... I'd hate to throw something out that someone would want... but I'm buried in too much stuff. The dumpster may be here as soon as next weekend. Local pickup is free (with donations/trades appreciated). If I have something you want and I have to ship it, I'm going to want $5 to $10 (to cover materials/time/gas) + actual ship cost. I can't even begin to cover adequately what I have here.... if ppl don't come up with enough 'do you have any XYZZYs ?' I'll try to make a list of the stuff (but it will be far from complete). -- Curt

SCSI to IDE bridges... (and useful info for PDP-11 users)

by tiggerlasv＠aim.com

I have used the Acard AEC-7720U SCSI <> IDE bridges. Thusfar, I have tested them with a few different brands of IDE drives; a Caviar 2100, a Fujitsu MPA3026AT, and a Samsung SV04232A. I have also used various sized CF cards, hung off the appropriate adapter. During my testing, these?were attached to a PDP-11, via a number of different Q-bus SCSI?controllers: CMD CQD-200/M CMD CQD-220/M Dilog SQ706A Emulex UC07 All performed similarly, and I had no trouble?formatting and using the attached IDE disks and compact flash cards. I don't pretend to understand the internal workings of the bridge card, but it appears that the bridge auto-detects the capacity of the IDE drive, and?translates that information to the SCSI side. I don't know if there is any limitations to the size of the IDE drive used; my testing was under RSTS/E, hence I couldn't use anything over 2.1 gig. (Some older IDE drives support a 2.1-gig clip, which works well.) Your mileage may vary. If you don't need alot of storage, they do have these available on-line: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=360087484205 That at least eliminates the additional?IDE <> CF interface, and makes for a smaller form-factor.? There are less expensive models floating around on e-bay, if you look carefully. For those with deep pockets wanting a one-piece solution to SCSI <> CF, there is also this little puppy: http://www.reactivedata.com/3-SCSIBridgeEmulators/legacy_scsi.htm As info. . . . T

That ubiquitous black foam

by IanK＠vulcan.com

I haven't seen anyone discuss this (nor is Google showing anything), so for all of you doing DEC restorations out there, I thought I'd pass along something I learned. DEC loved that black filter foam that falls apart after fifteen or so years. I'm restoring a couple of VAX-11/785s and they were liberally dusted with black foam detritus. So I took a piece that wasn't beyond recognition to a local shop here in Seattle called Friendly Foam (www.friendlyfoam.com). They identified it as "40ppi (pores per [square] inch) reticulated foam." They were also kind enough to sell me several square feet of it. They warned me that yes, it will still fall apart after a couple of decades, but for now it looks sooo nice. The machines I'm restoring have good paint, so with the new foam in place they look like they just left Maynard. It's funny how the little touches make such a difference. BTW, they also found adhesive-backed foam that is an exact match for the stuff DEC used on the cardcage cover panels. I hope this helps everyone who's trying to keep their Olde Beastes healthy and happy. - Ian UNIX is user friendly. It's just selective about who its friends are. Ian S.

The Crossbar System That Controlled MIT Trains

by johnmcnamara1＠verizon.net

During the period 1962-1966, members of the Tech Model Railroad Club of MIT conceived and constructed an unusual use for telephone equipment that functioned essentially as a combinatorial network. Specifically, they used five10x10 crossbar switches and more than 100 wire-spring relays to construct a control system for their large HO-gauge model railroad. Pictures of this control system can be seen at http://tmrc.mit.edu/progress/images.tcl?year=2002&month=5&day=26. Like all good electromechanical telephone systems, it remained in service for almost 40 years, even surviving a move between buildings. In 2002, it was replaced by an electronic system (not related to telephone systems) and retired to the New England Museum of Telephony ("The Telephone Museum") in Ellsworth, Maine, where it has been stored since that time. Unfortunately, the folks at that museum have decided to "de-accession" it, as it is not really part of their mission, and is taking up too much space. It is also likely to get damaged by future activities near its present location. If you have confirmed that someone or some organization would like it, please let me know. The deadline before scrapping begins is October 15th.

something's missing from my kit

by jeffj＠panix.com

I have a Nicolet Z80 NICE in-circuit emulator. Unlike a logic analyzer, it MUST replace the CPU (cannot just clip over the CPU since some signals are asserted or blocked). 1) The 40 pin DIP's pins are on the bottom of the box so it plugs in directly, if there's space. If there's NOT enough space, it comes with a ribbon cable but with .6" 40 pin dip-PINS on both ends. Mine came with a hand-made PCB with 2: 40 pin sockets hand-wired together to act as a F-F adapter. Is there are more "graceful" way to handle that, such as a female/socket 40 pin DIP connector directly to ribbon cable? There are compact gender changers for DB9/DB25 RS232 connectors, why not something similar for 40 pin DIP? 2) What if the CPU is soldered to the board? Must I desolder it entirely, or just certain pins? Thanks! Jeff Jonas jeffj at panix.com

DEC 5' cabinets for sale cheap!

by sellam＠vintagetech.com

I have about 7 complete 5' standard 19" cabinets for sale. I'm not sure if they are genuine DEC (they are branded Helgeson Nuclear Services) but they used to hold DEC equipment. See them here: http://siconic.com/crap/racks/ They have front and rear (locking) doors (some have key, others do not), removable sides, an internal power strip, and come with optional blower. I'd like $25 a piece, or give me $30 and I'll throw in a blower. The price will approach scrap value as the quantity you buy increases. I mean, really, offer me anything more than scrap value and you can have it. Priority (and the lowest price) goes to someone who says they want them all. These will go to scrap in a few days if there are no takers. Please contact me directly!

Keyboard Needed for Wang 4205 Terminal

by david_comley＠yahoo.com

Anyone on the list have a Wang 4205 terminal keyboard going begging ? Or even a complete 4205 terminal ? I will be bringing up a Wang VS45 in the next month or so and it'll be a challenge without a working terminal for the console. Thanks, -Dave

Looking for some Apple II hardware...

by ian_primus＠yahoo.com

While my primary interest has been larger machines (Prime, DEC, etc.) for quite a while, I've begun to start working with the micros again. Specifically, the Apple II. I regret giving away a lot of my extra hardware several years ago. I have working IIe systems, but I don't believe I still have a complete II+ - I know I have one in storage with no keyboard, though. So, I'm looking for a few machines, Apple II or II+, or clones. Working or not, I'm not picky. Surely someone has raided a school sale lately and has a heaping pile of them... -Ian

The Crossbar System That Controlled MIT Trains

by evan＠snarc.net

This clearly belongs in the MIT Museum in Cambridge, or in the Boston Museum of Science. -----Original Message----- From: John McNamara <johnmcnamara1 at verizon.net> Subj: The Crossbar System That Controlled MIT Trains Date: Fri Sep 26, 2008 2:53 am Size: 1K To: cctalk at classiccmp.org During the period 1962-1966, members of the Tech Model Railroad Club of MIT conceived and constructed an unusual use for telephone equipment that functioned essentially as a combinatorial network. Specifically, they used five10x10 crossbar switches and more than 100 wire-spring relays to construct a control system for their large HO-gauge model railroad. Pictures of this control system can be seen at http://tmrc.mit.edu/progress/images.tcl?year=2002&month=5&day=26. Like all good electromechanical telephone systems, it remained in service for almost 40 years, even surviving a move between buildings. In 2002, it was replaced by an electronic system (not related to telephone systems) and retired to the New England Museum of Telephony ("The Telephone Museum") in Ellsworth, Maine, where it has been stored since that time. Unfortunately, the folks at that museum have decided to "de-accession" it, as it is not really part of their mission, and is taking up too much space. It is also likely to get damaged by future activities near its present location. If you have confirmed that someone or some organization would like it, please let me know. The deadline before scrapping begins is October 15th.

drive mounting plate

by rtellason＠verizon.net

I have here what appears to be a drive mounting plate, of the sort that what my admittedly fuzzy memory is telling me was used in the Wang PC (not yer typical clone). It's a fairly heavy bit of metal, seems to have holes in it suitable for mounting a 5.25" drive, one folded-down lip to mount it to the box with, and a bit of a tab sticking out the other side, which was probably for orientation (I haven't seen one of those for probably 20 years or more). Anybody have a use for this? If not, it goes into the scrap metal box... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

Iomega card documentation...

by geneb＠deltasoft.com

I've managed to find an 8 bit ISA SCSI card that I've identified through it's FCC ID as an Iomega PC800 SCSI host adapter. I've been unable to find jumper settings or info on this card via Google. Can someone point me to where I can find the settings for this card? Even Total Hardware 99 comes up short. thanks! g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind.

SCSI to IDE bridges...

Information about the Acard AEC-7720U is available on Acard's website: <http://www.acard.com.tw/english/fb01-product.jsp?idno_no=23&prod_no=AEC-772…> The 7720U includes mumble-HBA support so it does support large drives over 128 GB or 137 GB or whatever that limit is. Of course some older computers do not support partitions that large. For example, a 750 GB drive on a Mac SE/30 would need the drive broken into 375 partitions... > Any idea if this outfit combines shipping? They're charging a pretty high > shipping cost for something like this. I don't know if they combine shipping. $10 for shipping does seem excessive, especially since the things don't weigh anything. Also, those are used 7720Us and do not include the power dongle. However, the power dongle is simply a 'Y' splitter which terminates in a regular hard drive power connector and a floppy drive power connector. Your hard drive needs a power connector of course, and the 7720U draws its power >from a floppy style connector. That style of splitter is getting harder to find, but many of the folks on this list may have them on hand--or a regular two-hard drive splitter and a hard drive to floppy drive power adapter. Oh, and the Ebay guy doesn't ship internationally. I'm not trying to be discouraging; it's still a very good price, but there are some details buyers should be aware of. I feel free to point these things out since I sold the last of my *new* 7720Us ($39 + $4.85 shipping with power dongle) a couple of weeks ago. :-) Jeff Walther

PDP-11/23 available in Vancouver

by borisg＠unixg.ubc.ca

I'm in the process of moving and have to get rid of my Minc system. I'd love to keep this machine but maintenance of domestic harmony necessitates going to newer (ie considerably smaller) embedded systems for data acquisition. The complete package consists of: MINC - 11/23 + 512 Kb RAM + A/D, D/A, Clock and lots of expansion room in the box which is in the orginal rack mount and on wheels for "portability" 2 RL02 disk drives 2 RX02 floppy drives (1 mounted with Minc + 1 spare) About 10 or so RL02 disk packs 1 large box 8" floppy disk boxes Several boxes of Minc manuals as well as a set of RT11 manuals Depending on the home situation, I might have to throw in another 2 smaller 11/23 systems and a large box of 11/23 boards of various kinds. Whoever wants this can have it for free but the deal is you have to come and pick it up and also take all of the materials. The last time I had this system running was in 1993 when it worked just fine as a data acquisition front end for my Mac and room heater. It hasn't been powered up since and I can't guarantee that the power supplies will still work. I've taken photos of the system and will post them on my website once I have time. I'm hoping to be out of Vancouver by the end of October so would like to find a new home for this system by them.

Z80 home brew with FDC

by les＠frii.com

I don't remeber who made the chip, but I made several diy z80 machines using a 279x. The 279x had an internal pll data seperator. All that was needed externaly was a cap and resistor as I recall. Les

random Q from a non-list member...

by jon＠jonworld.com

Hi everyone! I'm in the process of reviving an Atari pong system circa 1975. It's actually a tele-games pong (Sears branded.) All the circuitry is Atari, of course. Can anyone point me in the right directions for schematics for this beastie? Does anyone even have one and can just tell me what resistor or cap or other fun toy is missing from C15 in this admittedly huge graphic? http://www.showyourmedia.com/files/1222309713.JPG Thank you! -Jon jon at jonworld.com
