Toys R Us game trade-in program (including classic games)

by aliensrcooluk＠yahoo.co.uk

Hi, Now I'm not suggesting that anyone here wants to give up their game collections, but I'm just curious as to what peoples opinions are about Toys R Us's decision. Are retro games really worth that much, or are they just after the scrap metal and boards??? "Toys R Us is rolling out its video game trade-in program nationwide today, allowing customers to sell games from as far back as the (OMG!) Intellivision. Those who use the program will receive gift cards for the value of their trade-in, which can be used for any product at Toys R Us, Babies R Us or online at Toysrus.com." http://www.joystiq.com/2009/09/10/toys-r-us-rolls-out-national-game-trade-i… Regards, Andrew B aliensrcooluk at yahoo.co.uk

Looking for RLV12 (Q-Bus RL02 controller)

by derschjo＠mail.msu.edu

Anyone have one going spare to part with? Finally got a bootable RL02 pack for my 11/40 (thanks again, Dave!) and it's a no-go -- the drive is reading _something_ at bootstrap, but what ends up in memory looks like garbage. Unsure if it's a drive, controller, or CPU problem at this point. Looks like I'm going to have to start doing some debugging on the drive, and I'd rather do it from a system that I can more easily boot diagnostics from like my 11/73. (Plus it'd be nice to have another means to read/write RL02 packs, since my 11/73 has ethernet & scsi...) Thanks as always, Josh

Front panel switches (WAS: You just can't buy these anymore)

------------------Original: Date: Thu, 10 Sep 2009 12:12:06 -0700 From: Eric Smith <eric at brouhaha.com> Subject: Re: Front panel switches (WAS: You just can't buy these anymore) M H Stein wrote: > In my days with Burroughs systems, the operator consoles that had > "front panels" and many of their maintenance panels used illuminated > momentary push buttons that toggled on/off; that always struck me > as more intuitive (not to mention faster to set up) than separate lights > and switches. > The DEC KI10 (PDP-10 processor ca. 1973) did that also, as did the Fabritek BI-TRAN SIX. It is NOT faster for data entry, because you effectively have to manually XOR each entry with the previous one. It might be OK if there were a clear button (as there is on the BI-TRAN SIX), or if the entry word cleared itself after deposit, though the latter would be bad when you actually want to enter consecutive identical non-zero words. Toggles (with suitable handles) are much easier for binary entry, because you can push them up or down without regard to their previous state. With practice you can easily enter octal data three bits at a time using three fingers. --------------Reply: Good point, but as expressed elsewhere I suppose it depends on personal preference, what you're actually doing, and what you learned first. I can see that for data entry toggles could be faster, but my experience was mostly examine/deposit etc.; never had the exhilarating experience of actually "typing in" a program that way, alas.

Toys R Us game trade-in program (including classic games)

by feldman.r＠comcast.net

It looks like they will be resold, as the price they offer differs on whether the game is complete ("A complete game must include working game (scratches are OK), original case and cover art. The manual is preferred but not required.") or incomplete ("An incomplete game must include a working game (scratches are OK). The box, artwork and manual are not required."). It also varies by game. http://www.toysrustradeincenter.com/Terms.aspx The trade-in web site is not part of the regular Toys-R-Us site, so it does look like it is somewhat separate from the regular corporation.

dg/ux filesystem paper

by john_finigan＠yahoo.com

I recently saw an old academic paper out of Clemson that had this bibliography entry: M. H. Kelley. A look at the DG/UX file system. Technical Report 3, Data General Corporation, 1990 Anybody have any pointers on getting a copy? I've seen no trace of it on the web, and actually very little DG/UX info in general (even some man pages would be interesting), but the ancient marketing stuff I have seen makes me suspect they had one of the earliest journalling FSs in UNIX, and I'd love to know if that was really true.

You just can't buy these anymore

by IanK＠vulcan.com

One of the few items damaged in the shipping of our PDP7 from University of Oregon was a handful of the front panel switches. The switches themselves are a standard telephone switch and are still available! But the long, tapered bat handles were unobtainium. So, one of our folks with above-average mechanical aptitude *made* some for us: http://www.youtube.com/watch?v=0hUEPfgKJwY Pretty cool, huh? UNIX is user friendly. It's just selective about who its friends are. Ian S. King, Sr. Vintage Systems Engineer Living Computer Museum A project of Vulcan, Inc. http://www.livingcomputermuseum.com

Front panel switches (WAS: You just can't buy these anymore)

by dm561＠torfree.net

Speaking of front panels, I've always wondered: In my days with Burroughs systems, the operator consoles that had "front panels" and many of their maintenance panels used illuminated momentary push buttons that toggled on/off; that always struck me as more intuitive (not to mention faster to set up) than separate lights and switches. Granted it would require extra logic to latch the states, but was that kind of front panel ever used on any of the micros and minis that we discuss here? mike

SunBlade 2000 vs SunBlade 2500 vs Ultra 45

by rescue＠hawkmountain.net

Might be pushing 'classic' a bit.... as the 'oldest' of these three is only 7 years old.... so... if these aren't 'classic' enough yet... please forgive me :-) So.... which one is best in your opinion ? The 2000 takes UltraSparc III, 8MB cache (at 200mhz bus), the 2500 and U45 use UltraSparc IIIi, 1MB cache on chip (but how are the cycles to it ?) Beyond that, memory tech differs... 2000 takes ?, the 2500 takes ECC DDR266, and the U45 ECC DDR333. The 2000 and 2500 do SCSI, while the U45 does SAS/SATA. But beyond that, how is reliability, how is USIII vs USIIIi performance ? The 2000 will do vertical UPA, right ? (I have some C3D cards from U60) The 2500 looks like fastest slot is 64 bit 66mhz 3.3V PCI (so what Sun GFX cards go in there?). And the U45 has PCI-X and PCIe x16. (I assume graphics there is usually via the PCIe x16, right ? Looking for 'best' desktop Sparc.... assume it would be one of these three, no ? Thanks, -- Curt

Vintage Intel Computer - Intellec MDS questions

by seanm＠cae.com.au

Hi Joe, I came across this page and this comment from 2005: http://archive.netbsd.se/?ml=cctech&a=2005-01&t=640496 "Actually I have a pile of iSBC 215 HD controller's but they're configured for the 86/330 systems and I don't have the proper PALs and jumper settings for them for use in the MDS systems." I found your e-mail addresses elsewhere. I sent this e-mail to both the addresses hoping that one will still be active after four years. I was wondering if any of the cards are serviceable and would already be suitable as HD controllers for an INTEL 86/330 system. If so, might you be willing to sell any? The details for the controller of interest are: Description: Winchester Disk Controller. Part Number: iSBC 215B Host: Intel 86/330 with RMX86 operating system. Cheers, Sean McHugh

Omrom programmable terminal

by tponsford＠rnsmte.com

I picked up a Omrom programmable terminal. Picked up is the operative word as the thing weights around 70 pounds! It appears to work in spite of a disjointed space bar (fixed) and the model number is 8030. There is a rotary knob on the back that sets the baudrate (up to a whopping 4800 baud) and what appears to be 4 rs-232 ports, one parallel port and a coax port labeled TV ?? Anyone ever use these? is there a manual/pdf out there. A google search does not appear to bring any good results. It does have a cool NASA/DOD sticker on it! Cheers Tom P.

FFS: Tadpole SparcBook

by silent700＠gmail.com

I have here a Sparcbook laptop by Tadpole which will go free for the cost of (not insubstantial) shipping to a good home. It works when it wants to. The AC adaptor is good, however the power connector on the mainboard may be loose. Sometimes it boots; often it does not. When it does boot, it boots up a login and I was able to log on as root with a blank password. Included with the Sparcbook are: - AC Adaptor - CD of Solaris 1.01 for Sparcbook (Version A.) - (2) floppy set of SoftPC Ver 3.05 for Sparcbook Solaris - Sparcbook 1 User Guide - Sparcbook 1 SoftPC Installation Guide - Solaris 1.0.1 Sparcbook version Release Notes I also have second copy of the Sparcbook User Guide which I will send to anyone interested in that piece only. Shipping will be from 60074 zip. Local pickup is welcome. If I do not have the proper shipping materials here, then I'll have to go to the UPS store and have them box it up, so extra charges may apply there. Thanks -- jht

N8VEM "twofer" special

by lynchaj＠yahoo.com

I went and looked at the pictures, but I could not get a sense of the size difference between boards. Is there an appreciable size difference? Jim Hi Jim! Thanks! Yes, there is a size difference. The N8VEM PCBs are Eurocard 160x100 mm standard. The mini-N8VEM is slightly larger about a centimeter or so larger on length and width. It won't fit in a Eurocard rack but is still small enough to work fine as a stand alone SBC. It will also plug into the N8VEM ECB backplane. There is a lot of information available on the wiki and you may want to consider asking questions on the mailing list. All the files for mini-N8VEM SBC are available in the Eagle format including schematics and PCB layout. If you want anything else just ask and its probably available. Thanks and have a nice day!

Manual for Mountain Hardware RTC S-100 Board

by monahan＠vitasoft.org

Dear Sir, I have started putting together a web site www.S100Computers.com completely focused on S-100 based computers. This is strictly a hobby. I think there is a need for a good central place that describes the different S-100 boards that anybody can quickly go to. I think it is important to try and get all this stuff together while we remember it for later generations. Be it other hobbyists or serious historians etc. In particular I am trying to get all the old manuals. Anyway, I am working my way through the different companies. I am currently doing the company Mountain Hardware. I wondered if by chance you have or could make a .pdf file for the manual for the Mountain Hardware 100,000 days clock board. I see some time ago you listed it under "my CP/M-80 pile'o'gunk". Alternatively if you are comfortable with it, I could scan the manual myself and return it to you.

Thanks and have a nice day! > > Andrew Lynch [AJL>] Jim, There is a complete set of mini-N8VEM v8 files in this directory on the N8VEM wiki. James designed the mini-N8VEM using the N8VEM SBC as a guide but to more reflect his personal design goals. The two systems are compatible but the SBCs are quite different. I think James did a great job and I use my mini-N8VEM SBC all the time. It has a lot of advantages over the original N8VEM SBC especially as stand alone board. http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder&param=Mini%20N8VEM%20Fi les There are a number of what I would consider associated N8VEM projects or even "spin offs" mini-N8VEM being one of them. There is another SBC project in the UK using the N8VEM SBC design, etc. Also builders designed the DSKY as debug/monitor front panel type device. Again, a great project and I use it all the time. Another builder made the PockeTerm which I also use daily alongside the N8VEM project and so on. Making a frame work for home brew computing project is the whole point of the N8VEM project so I am 100% supporting these associated projects. Much of the development recently on the N8VEM project has been for adding full floppy drive capability in CP/M. We've been testing an improved CBIOS that supports the floppy drive. It is fully functional now and there is an optimized one in testing. With deblocking support and head seek optimizations it is *much* faster and works really well. The new version is on the wiki in the DiskIO folder for testing. The performance increase with the floppy drives, IDE and ATAPI devices is really quite remarkable. Thanks and have a nice day!

I had seen those machines, many many years ago. It was a world of escalating copy protection on one side and copy protection defeating tools on the other. And the media duplicator guys were a little stuck in the middle :-). All that said, in the DRY principle there is the problem of going into analysis paralysis. If you devote yourself too strongly to the principle of a single end-all-and-be-all application you can find yourself not doing anything useful at all. In fact, until you've repeated yourself several dozen times, you probably don't honestly have a good idea of the broad range of abstractions or at the very least parameters you'll need. Sure, I might have 20 years experience with one particular brand of disk format or communications protocol... that does not give me the breadth I need to think that I understand them all! School of hard knocks rules above all else. Tim.

Old IDE to USB?

by jfoust＠threedee.com

Late 80s, early 90s IDE drives don't show up on the IDE-to-USB adapters I'm using for other applications these days. I assume the older drives don't self-identify their geometry or handle newer parts of the IDE spec that these contemporary devices depend on. Any advice for USB-based reading of old drives on new equipment? For that matter, I'd consider investing in the more professional levels of drive reading devices. These $30 USB devices aren't doing it for me. I want a better chance at read dying drives. - John

Wanted -- Amiga Devcon article, or Trace disc duplicator docs

by classiccmp＠philpem.me.uk

Hi guys, I'm currently mid-way through the floppy disc reader project -- or at least the hardware part of it. Current status is that the USB PIC is talking to the FPGA (i.e. I can write to the chip's registers, read the registers back and the LEDs on my Cyclone II Starter Board blink in neat patterns). Big thing is that I haven't soldered the Shugart interface together, so it won't talk to a disk drive yet. It does, however, seem to be writing to the SRAM, and the timing values seem somewhat sane (or at least close to what my TTL generator is spitting out). What I'm after now is an article from the proceedings of the 4th European Amiga Developer Conference, held in Milan between the 10th and 14th of September 1991: From Programming to Finished Product by Roberto Donelli (Soft Service Division Director, MEE S.p.A. - Milano) The reason I want this is because it contains an example "Freeform" script (format description) for an Amiga floppy disc. I'm looking into ways to describe a disc image in generic terms -- that is, you write a script that describes the format, then the software drivers can use that description to convert timing data (the time between flux transitions) into data (and vice versa). To put it another way, this is the "DRY" principle -- Don't Repeat Yourself. Why write two dozen programs to decode various disc formats, when one program and a couple of scripts will work just as well (and be easier to maintain)? From what I can gather, the Freeform language was designed by a company called Magnetic Design Corporation, for the "Trace" series of disc duplicators. So if someone has the docs for a Trace machine kicking about, I'd hazard a guess that a copy of the chapter on the Freeform language would be just as useful... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

N8VEM "twofer" special

by lynchaj＠yahoo.com

Hi! Thanks to my good friend James the N8VEM home brew computing project is offering its first ever "twofer" special. If you purchase an N8VEM SBC PCB for $20 plus shipping for an additional $5 you will receive a special edition mini-N8VEM version 8 SBC PCB. Why two SBC PCBs? At the N8VEM home brew computing project we have found that the best tool for building your own N8VEM SBC is to have its brother the mini-N8VEM SBC running along side! I have both the SBCs and use both frequently for a variety of tasks as do several of the N8VEM builders. Believe me, you'll get used to having both! There are 22 mini-N8VEM SBC PCBs available and this special will only last as until the mini-N8VEM PCBs run out. The N8VEM home brew computing project is completely amateur and non-commercial. All software and hardware design information is free and publicly available. Please join us on the N8VEM home brew computing wiki and mailing list for more information! http://n8vem-sbc.pbworks.com/ http://groups.google.com/group/n8vem Thanks and have a nice day! Andrew Lynch, 73 de N8VEM PS, this is a video from an advanced N8VEM builder demonstrating his N8VEM SBC with optional ECB backplane, DiskIO board connected to an IDE hard drive and floppy drive, DSKY front panel, and ECB bus monitor all working simultaneously. You can see him running CP/M 2.2 and copying files from the IDE hard drive to the floppy drive. Notice the data streaming past the ECB bus monitor. The DSKY is displaying floppy drive Track, Sector, Status 0, and Status 1 from the DiskIO floppy drive controller. http://n8vem.googlegroups.com/web/copy.avi

Another "oldest computer" story...

by jules.richardson99＠gmail.com

[I've not been reading the list for a little while, so apologies if this has been mentioned already] The Harwell Dekatron Computer - aka. WITCH - has just arrived at TNMoC for restoration. Once completed, it'll be (as far as we know) the oldest functional, complete, stored-program electronic machine in the world (some careful qualifying there, because of course it's one of a handful of 'pioneering' machines, all of which have their place in history). Lots of links to news items on the machine at: http://www.tnmoc.org/inthenews.aspx Plans for the machine date from 1949, with it first running in 1951.

Old IDE to USB?

This may not apply to your case but... Remember that old Western Digital drives will not work unless you use the "Single" jumper setting on the drive. Setting them to Master in a single-drive setting does not work. For that matter, did you set the Master/Slave/Single jumper? Older drives are also less likely to work with Cable Select. Jeff Walther

Even the markings on the relays look very familiar. I hope they are more reliable than mine though, as the machine seems to be using them for actual computations. I suppose they would be fine with routine maintenance, usually consisting of dragging a bit of punched card between the closed points. Roger Holmes.

I still wouldn't do it, some SMPSs can self destruct without feedback. > This is also a small part... wouldn't it be dissipating a large amount > of current clamping the rail from 12+V to 8.5V? No, it's not used as a clamp like that. The 12V will be divided down by some R and the pot so that normally 2.5V would be on the REF pin. The K pin then sinks current that is the feedback to regulate the voltage. This is often the LED side of an optoisolator. > I have an ESR meter. So do I.

> Anyone got any ideas as to the oily film ? Most likely it is from a capacitor. > If this is acting up, for testing purposes it would seem to be safe > to remove it to see if the voltage changes (jumps back to around 12V) ? No, that would remove all regulation from the 12V rail. You can test this part out of circuit. Connect REF to K, pins 1 and 3 on the TO92 part, and these two to +5V through a 680 or 1K ohm resistor. Connect A, pin 2,to ground. With the 5V on you should read 2.495V +/-2% between K and A. This part can be replaced by a TL431, LM431 or equivalent. > So, suggestions, ideas on the film, and best way to go about > troubleshooting the 12V rail are welcome :-) An ESR meter to test caps is pretty much essential. Some obviously fail but others can look fine but still be high R. Electrolytics are by far the biggest single cause of switch mode supply failure. Lee.

VAXStation 4000/90A

by pontus＠update.uu.se

Hi All. I'm taking my first stumbling steps into the world of VAXen and VMS. Before I sink my teeth in the bigger machines I have, I've decided to see if I can get my VAXStation 4000/90A to run. It seems mostly okay, I can boot the VMS cd I have. But there is one message that concerns me. During the self test I get this: ?? 000 8 SYS 0512 That last number is not hex, if I type the following >>>show err I get ?? 000 8 SYS 0200 And I guess 0200 is hex. Either way, in the manuals I have found, I can read that the test for device number 8 is checking the systems ROMs and that this indicates a checksum or read error. The error code shown is not listed in the manuals. Should I worry about this? Can it be remedied? Kind Regards, Pontus.

switching power supply Q

by rescue＠hawkmountain.net

So, the problem with my OKIStation is the power supply. 5V is solid... but 12V was only putting out 8.5 volts (with no drive load attempted... unsure if the motherboard uses 12V for anything). I have found there is an adjust for 12V, I have not touched it as of yet. In getting that far, that small pot, 2-3 resistors, a 3 legged "IC1" (NEC C1093) and that area of the PCB have an light oily film on them. The IC1 and the little pot seemed the worse. I'm not sure what this could be... I've never seen a transistor/IC/ etc emit an oily film... I can't see it coming from the trim pot, and even though there are a few nearby capacitors... they don't have a film on them.... and I've only seen capacitors ooze brown scum. If there are no failing components, then either the trim pot has gone dirty... or that "oil" ? has got into it and is causing it to ohm out wrong. As there is no way I'd find another of these supplies, my only option is to fix it. Anyone got any ideas as to the oily film ? Looking up IC1 on the net I find http://pdf1.alldatasheet.com/datasheet-pdf/view/6668/NEC/C1093.html which indicates it is an adjustable precision shunt regulator. In the test and application circuit section of the pdf, this device goes across Vout. If this is acting up, for testing purposes it would seem to be safe to remove it to see if the voltage changes (jumps back to around 12V) ? The oily film puzzles me... I don't see any sign of bad caps... and this power supply seems to be well engineered (has temp probes on the switching transistors presumably to shut down the supply should things get too hot). Being a three board supply design with several connections soldered ... it hasn't been a joy to get apart this far :-) So, suggestions, ideas on the film, and best way to go about troubleshooting the 12V rail are welcome :-) Thanks, -- Curt

Teletype ASR33 with modem

by iamvirtual＠gmail.com

I am looking for information for my recently acquired ASR33 that has an Anderson Jacobson modem (ADT-233) built into it. I have retrieved the documents for the base ASR33 from Bitsavers and University of Queensland, but it doesn't look like any of the manuals describe the modem. The modem is complete with the acoustical coupler. :-) The modem does have a Teletype sticker on it and describes it as a UCC-6. I need to know how to hook the ASR33 to my PDP-11 using a 20mA connection. I am looking for user guides, technical details and schematics. Thanks! --barrym

Old IDE to USB?

Has anyone ever seen a USB-to-IDE adapter that can handle the old drives and devices, presumably by allowing you to specify the Cyl/Hd/Sec? After reading http://en.wikipedia.org/wiki/Parallel_ATA , I'm surprised to see that although IDE drives appeared in the late 80s, the ATA-1 standard didn't arrive until 1994. Based on the chart there, I'm guessing that today's USB-to-IDE devices (as well as near-recent onboard IDE) simply don't support the old PIO transfers and only handle the post-1998 ultra DMA transfers? - John

NCD 19r monochrome Xterm

by ethan.dicks＠gmail.com

Hi, all, I have the opportunity to pick up a couple of NCD 19r mono Xterms locally, if I want (someone else declined due to lack of basement space). I have not tested them, but I can. Doing a bit of digging, I see that folks have offered them on numerous mailing lists over the years (including suns-at-home, and I think here) and frequently get no takers, so it sounds as if they have no assignable cash "value". Does anyone here have any experience with them, how hard it is to find the software for the tftp repository? (I did a non-exhaustive search and haven't found any yet) Besides performing their obvious function (serving a mono framebuffer, mouse, and keyboard), are they neat in any way, or are they part of the dustbin of history? They are kinda large, so I'm not exactly eager to move *more* large CRTs into my house without good reason. I'm seeking a reason. I already have an HDS xterm that I got working some time back, but it's just a slab - you use your own monitor. *That* doesn't take up too much space on the shelf. A large glass bottle does. Thanks for any input and/or stories about the NCD 19r. -ethan

Certainly sounds like Julian-day-hour-minute-second to me, just like all the timecode displays I've ever seen going back a good chunk of a century :-). I looked through the truetime schematics I have and none of yours match exactly so maybe some other brand. Some similar displays are sometimes used in video and movie editing and production (think those LED slates), although there the 3- or 4-digits would probably not be day, but some sort of sequence number, dunno for sure, I only briefly touched Hollywood :-) Tim.

Looking for info on three multi-digit LED assemblies

by ethan.dicks＠gmail.com

I have a box of LED displays that I picked up all at once from a Hamfest, probably either Dayton or Mansfield. There are enough similarities between the three types that I figure they are from the same maker. I don't have any easy way to take pictures right now, but I can post the relevant characteristics to see if anyone has any recognition. They seem easy enough to reverse-engineer, so while I'd love schematics or other documentation, I'll be able to use them without. I'm mostly curious what equipment they might have come out of. #1 - the oldest style. Marked "assy 4000123-101". Three double-digit MAN6610 displays with a "336" date code on a "front board" attached to a driver board by dozens of individual 330 Ohm 1/4w resistors used structurally as well as electrically. The driver board has six 74LS47s with date codes of "231". There are four lugs on one short edge of the board with cut wire stubs, E1 and E2 have orange wires, E3 is blank, E4 has a black wire - +5V and GND. The data comes in on 30 individual wire-wrap stakes with the stubs of the old WW wire still on them, BCD data plus latch x 6. #2 - the middle board in age and appearance. Marked "assy 4002244", with 4002243-1 on the front, it's a newer board with a solder mask, and has *five* dual-digit LED displays, HDSP-K121s, grouped as 4 digits and three pairs of digits - as if it could display year plus hrs/min/sec or DOY plus hrs/min/sec. It uses an unusual (to me) driver chip - *nine* of a Motorola MC14543 (date code 9026) which the datasheet tells me is suited for LCD driving. It also has the same power lugs on the short edge, E1-E4 with the same color stubs. There are 49 WW pins around a long and the opposite short edge. They appear to be strangely numbered, first in nine groups of four, then with ascending numbered pins adjacent to the groups (probably BCD plus latch), with the last four pins over on one short edge. Both of these displays have pins that are not aligned nor spaced to permit a ribbon cable or molex or Berg connector to easily attach, and in fact, both still have wire-wrap wire stubs, so they appear to have been somewhat permanently attached to their surroundings. They also take an enormous number of pins, but would be trivial to drive from 4-bit counters and such (thus the newer one would make a perfect display for a DOY+TOD clock made from discrete TTL or CMOS). #3 - much more modern design. Marked 4005935-1 on the back and 4005936-101 on the front. It has nine single-digit hpHDSP-E103 displays (date 852) driven by a pair of Maxim MAX7219CWG (date code 9611) 8-digit clocked-serial-interface LED drivers. It's physically grouped as three digits, then three pairs (DOY+TOD), and comes with a red plexi bezel with "error" over the bottom edge of the "single hours" digit and "dropout" over the bottom edge of the "single minutes" digit. Its connector to the outside world is a keyed and latched 3M 3408 connector - 2x8 0.1" spacing. So do any of these LED assemblies ring a bell with anyone in terms of type or brand of equipment? The only thing that even closely resembles a company name or logo is NTUF-1 near the commonly-seen '94V-0' legend. Thanks for any hints or suggestions, -ethan

Performance analysis for DOS apps?

by mbbrutman-cctalk＠brutman.com

I have been performance tuning my TCP/IP stack mostly by looking at the code and making educated guesses as to what needs to be fixed. I have just wasted a day rewriting the IP checksum routine in assembler for a few tenths of a percent improvement and I'm not terribly happy. :-) Is there a sampling profiler available that will periodically record the program counter and give me a histogram of what it finds when it is done? I'm thinking of something like oprofile on Linux. If it does not run in pure DOS but requires an emulation environment, that is ok too. I just don't know what any of the options are. Thanks, Mike

Do you have any words of wisdom? It's been over 6 years since I did this, and I don't have any ancient lore to draw from (back in the day, we didn't have Ethernet at work - everything was character terminals), but I don't recall anything specifically password related. Perhaps mine were never set or perhaps we have different models. The only issue I ever had was finding the right stuff to stick into the tftp repository to feed it when it was coming up. I am pretty sure I was running it off of a SPARCstation of whatever flavor I owned at the time, so once I stumbled across what I needed, I had to incrementally check the tftp logs to see what was being asked for and get it in the right place. I noodled around with a few apps from the Sun, then put it away since ISTR there were some warts with modern apps like Netscape and an ancient X term. It mostly worked, but I was better off logging into the console (in the same room). Sorry I don't have specifics to quote you, but if you want to send me the model number of what you have off-list, I'll check it against what I have and see if they are even the same. -ethan

Looking for measured power consumption of some old DEC minicomputers

by jgkoomey＠gmail.com

Hello all, I'm doing an analysis of trends in the energy efficiency of computation over time (for details, see the first report listed at http://www.intel.com/pressroom/kits/ecotech) . I'm using standardized performance measure from previous work by Bill Nordhaus at Yale, and then attaching measured power use to the machines for which Bill estimated performance. I got measured power data for the DEC PDP-1, PDP-4, and PDP-8 from Gordon Bell (now at Microsoft, who worked on these machines back in the day) but am seeking measured power use for some of the other machines listed below. I understand that some of these machines may not be unitary and so power measurements are more complicated. I'm interested in the sum of power consumption for the CPU, memory, and hard drives for typical configuration of the machines listed below.

What PSU for Apple //e Platinum?

by silent700＠gmail.com

I recently picked up the "Platinum" version of the Apple //e (the white one with the numeric keypad.) It appears to have a dead power supply. I see a number of PSUs on ebay and parts sites that are listed as "Apple //" compatible. Does anyone know if the Platinum used a different PSU than the other //e models? Also, did the //e use a different one vs. the //+ ? -- jht

Ongoing PDP11/34a resurrection attempts - stuck SACK?

by jplist2008＠kiwigeek.com

Greetings all; In my continued efforts to try and get my 11/34a functioning I decided to set up my logic analyser and trap ALL of the 56 Unibus signal lines to see if I could spot anything that was being held asserted when it shouldn't. For reference, my 11/34a is set up like: 1 M8266 -------------------------------------------| 2 M8265 -------------------------------------------| 3 M9301 YJ-----| FLIPCHIP 4 M7856---------------------------| 5 National Semiconductor Memory Board--------------| 6 G7232---------| 7 G7232---------| 8 G7232---------| 9 M9302--------| G7232---------| I only have the basic front-console, so not the lovely button-filled operators console. All the NPR jumpers are in place. All voltages check out. The symptoms are: Unit powers on, RUN light comes on and then quickly goes out. When the BOOT/INIT switch is toggled, again, RUN light on, then out. Clearly the unit is HALTing on something, but I can't work out what and nothing seems to appear on the console. When I analyse the bus the unit follows what, from the Unibus design manual, appears to be a standard start-up procedure. - All signals float (obviously) - All signals cleared, DCLO/ACLO/INIT asserted - 773000 is placed on the Address lines (as configured in the bootstrap) - DCLO negates - ACLO negates - INIT negates, and then immediately: - Address lines are cleared - SACK is asserted I find no mention of SACK being asserted in the Unibus manual in its start-up section. Furthermore, as my understanding goes, SACK should only be asserted when a bus master has accepted a grant and is beginning a transaction cycle. There is NO activity on the request/grant lines, so nothing should be allowed to become bus master, so I think this SACK signal should not be happening. Can anyone with more understanding than me (which, you know, is pretty much everyone else who owns a PDP11) confirm I'm not completely off-base here? I have two M7856s and have switched between them, so if it's the 7856 that's holding SACK, then both of mine are doing it. Elsewise... I think the only thing that could be "sticking" is the processor boards, as the memory card shouldn't be able to assert SACK since it can't become a bus master. If this guess is correct... I'm not really sure how to begin debugging what on the processor board is getting glued. Time to break out those schematics? My thanks to all for your thoughts; - JP

Yes, that was clear, I just was suggesting that IF those tapes are diagnostics, I'd be interested in an image of them, and would be willing to help image them and then return the originals to the new owner...no problem.

Its > > {snip} Ooo...TU58 tapes, for/from an 11/750! Are these by any chance the various diagnostic and maintenance tapes, i.e. BD-xxxxx-DE numbers? Finding images of that whole 11/750 series has so far been unfruitful for me, and, as it turns out, I'm just about ready (finally, after nearly two years of infrequent fiddling with faulty power supplies) to fire up my 11/750 for the first time. I'd think it would be A Good Thing to have those tapes for checking everything out. If those tapes are indeed the diagnostics, I'm up for assisting in getting them imaged. So far I have been able to gather (with the gracious help of Barry M.) tapes: 1,2,3,5,6,7,8,9,17,20,33,41,33,44 and 51. I'd like to fill the gaps and will happily put my functioning TU58 drive to work getting more images if that is possible. Also, I'm looking for some blank/scratch TU58 tapes if anyone has some gathering dust. Happy to cover shipping, etc. Many thanks. -- Jared

Decwriter LA120 flashing 8

by chrise＠pobox.com

Bringing a Decwriter III LA120 back to life here and it's the first one I've worked on. Mechanically and cosmetically its in great shape but unfortunately, power on yields flashing "8" on the LED display. According to the technical manual this means "Microprocessor Failure". Hmm. Seems there's enough of a microprocessor there to get the display running and flashing 8 but apparently not enough to be a printer. Any words of wisdom as to likely suspects in this failure mode? The technical manual is great-- with lots of tests documented and scope photos etc so I'll eventually get there but of course I am looking for any hints as to common failures that others have already dealt with. Thanks. Chris -- Chris Elmquist

VCF East 6.0 update

by evan＠snarc.net

Hi everyone. Some updates re: VCF East 6.0: Sellam is working on the vintage.org site; he says the problem is his AT&T high-speed connection. A tech is coming to look at it tomorrow morning PST. If it's not fixed then Sellam will temporarily host the site elsewhere. He and I both apologize for the inconvenience. We're up to 18 exhibitors so far, and I've heard that people are coming >from California, Florida, New Hampshire, and Ohio. So, the rest of you cctalkers have no more excuses. :) Looking for lodging nearby the VCF East? Our venue is at 2201 Marconi Rd., Wall, N.J., 07719. There are several mainstream motel/hotel chains nearby. Anyone who arrives Friday night (Sept. 11) to help us set up gets a free VCF t-shirt. This year's shirts are black with a very cool (and funny) server room design in bright green. Vince Briel is still taking registrations for his PockeTerm workshop. It's only $60. While the VCF site is down you can directly access Vince's site at http://www.brielcomputers.com/workshop.html .... the workshop is Sept. 12 at 10am. David Ahl, of the former Creative Computing magazine, will lecture on famous blunders in microcomputer history, Sunday at 1pm. His lecture was an audience favorite at VCF East 4.0 in 2006. Saturday at noon is the first-ever VCF music concert!

VT420 Serial Lines

by healyzh＠aracnet.com

Is there some special setting I'm missing to make both lines talk to a computer, or are some VT420's only capable of talking to a printer on line 2? I typically have two computers plugged into the same terminal, or two lines on the same computer, but with this VT420 I can only get line 1 talking to the computer. Zane -- | Zane H.

Urgent help needed reading 5 1/4" floppies

by len＠shustek.com

The Northern California Innocence Project at Santa Clara University (http://law.scu.edu/ncip/) works to get wrongfully convicted innocent people freed from jail. Such convictions are infrequent, but tragic when they happen. In a case they are working on they just received permission to access reports of interviews done in 1986 which were recorded on 5 1/4" floppies. The problem is that the disks are in storage at the Fresno Department of Justice, and they will be given only one day to examine them there: this Tuesday, or possibly Wednesday. We suspect the disks -- about a dozen -- were written by an IBM PC. But all we know for sure, because we have a photocopy of one label, is that they are DS/DD soft sectored. They are looking for someone reliable who can bring a computer (or more than one?) to Fresno on short notice to read the disks and take copies of the files. Can anyone help? This is a 20-year-old wrongful conviction case and the stakes are very high. If you can help, please email me (len at shustek.com) or call me at home (650-851-3176). Thanks. -- Len Shustek

My intentions are to develop an interface to a PC to implement some virtual storage devices. If all goes well I'd like produce these cards in small volumes and so I'm keen to use off the shelf components as far as possible. The main problem of course is the bus receivers and drivers as these are pretty much unobtainable as far as I can tell. I'd therefore like to find suitable alternatives. Does anyone have any suggestions of suitable devices? Examples of chips I'm looking to replace are the DEC 8881 driver, DEC 8640 (or DEC 380) receiver. Thanks, Toby Search the CCtech archives for 'unibus transceiver': http://www.classiccmp.org/mailman/mmsearch/cctech?config=cctech&restrict=&e… Alternatively google for 'Am26s10cn'. It is about the closest to a true unibus transceiver that is still available (in a DIP package even). TI makes it, available from DigiKey. Don

Looking for measured power consumption of some old DEC minicomputers

by jgkoomey＠stanford.edu

Hi Zane, Forgive me if I'm not using the right method to reply as I'm new to the list. I didn't see Al Kossow's post in the archive. I think that including a peripheral might make sense if it were a big hard drive but not if it were a printer. Anything that is involved in core computations for the computer (as opposed to input or output) would be fair game. I know that these computers do vary widely but I'm willing to go with what machines are available for metering. The big uncertainty is in getting measured power use of any kind. The exact boards that are installed are not as critical. Any ideas for folks who might have metered their PDPs? And the key thing to keep in mind is that the trends in performance swamp any errors in the measurement of power use, so I just need to get in the ballpark on power for the data to be useful. Defining system boundaries is important, so the peripherals question is one that we'd need to discuss. Thanks, Jon On Thu, 27 Aug 2009, Al Kossow wrote: > Also, are you just talking about the CPU, or including peripherals? I was wondering this myself. This is an interesting topic, but it might be difficult to define a "standard" configuration for these machines. Even the contents of the CPU boxes can vary widely. I suspect that many on this list are like me and tend to limit what what boards are in our CPU's to just what we need. How many people really need the CIS (Commercial Instruction Set) portion of the CPU in their PDP-11/44's or 3 Serial boards for terminals? I also limit the drives to what I need typically (I've even been known to unplug CD drives on PC's). Zane Hello all, I'm doing an analysis of trends in the energy efficiency of computation over time (for details, see the first report listed at http://www.intel.com/pressroom/kits/ecotech) . I'm using standardized performance measure from previous work by Bill Nordhaus at Yale, and then attaching measured power use to the machines for which Bill estimated performance. I got measured power data for the DEC PDP-1, PDP-4, and PDP-8 from Gordon Bell (now at Microsoft, who worked on these machines back in the day) but am seeking measured power use for some of the other machines listed below. I understand that some of these machines may not be unitary and so power measurements are more complicated. I'm interested in the sum of power consumption for the CPU, memory, and hard drives for typical configuration of the machines listed below.

DATARAM unkown memory board help

by stephane.tsacas＠gmail.com

Hi, I have this DATARAM board, which only says "40734 rev B" on the solder side. It's populated with 2 x 18 MK4116 memory chips, so I guess it gives a total of 32 Kw. I don't know how to map it correctly in my PDP 11/05 address space, given that it already has a 4kw core memory mapped from 24 to 28 K. The 11/05 originally came with this setup, but I can't locate the MOS memory by LOAD/DEP/EXAM values every 4K from the front panel. The red led goes off when the bus is reset, and the green one is on. Does anybody know this card and the jumpers settings?

Unibus bits

by Paul_Koning＠Dell.com

One of my colleagues was cleaning out an old lab and came across some modules. I don't have any use for them but I figured someone here does. I have one M9014 "Unibus to H854 adapter board". (What is that, anyway?) Also, three M9202, those are the Unibus jumper cards with 2-3 feet or so of Unibus cable inside. If I remember right, those were supposed to be used to break up a long Unibus. I suppose they are acceptable as substitutes for the regular (M920) Unibus jumper. Any interest, please drop me an email. paul

Old password protected laptop drive

by teoz＠neo.rr.com

I recently won an IBM 540MB laptop HD for the old Thinkpad 755 series and I found out it is password locked. IBM DHAA-2540 Security level MAX All I want to do is erase and use the drive, to do that I run the ATA command security erase prepare, and then security erase unit. To do the latter you need a master password which I don't have (tried all spaces). Anyone happen to know what the default password would be for that series? If the master password was changed from default is it hosed permanently? Any other way around it so I can use the drive?

OEM Screentyper / network-capable ASCII terminals?

by jules.richardson99＠gmail.com

Mention of this on another group got me curious - anyone ever come across an 'OEM screentyper' before? From what I'm told it sounds very like a text-mode ASCII dumb terminal (Z80 CPU, ASCII display, diskless) - yet it has a network port on the back, rather than an RS-232 connection to some other intelligent machine. In other words, it sounds old and simple - but seems unusual if its connection to the outside world is via a direct network connection. I'm awaiting more details to see if the person who told me of it can recall if it was Ethernet or Token Ring or something else (and that it not being just RS232 via a non-standard connector can be ruled out), but I figure someone here may have heard of it anyway. I wondered if maybe it was a packet monitor or some sort of data logger rather than a data-entry device... cheers Jules

Programming 68764 EPROMs, redux

by cclist＠sydex.com

It dawned on me that perhaps a 200MHz P1 was too fast for my parallel- port programmer (M2L EZ-EP). I hooked the programmer up to a 16MHz 80386 system and bingo--the EPROMs blank-check and program correctly. Speed kills... Thanks for your suggestions. --Chuck

Round-pin mains leads (old HP, etc)

by ard＠p850ug1.demon.co.uk

Some older HP instruments (and I think other manufactorers) used a 3-pin power connector with round pins, not the flat pins used on the now-common IEC plug. I've seen this connector used on older HP9100s, HP5245 counters, and on the 9125 I at ve just bought. Does anyone know if the cables to fit said plug are still available, and if so, where? I don't care what's on the other end of the cable (bare wires are fine), but I would want it to stand UK mains [For all the seller cleaerly showed the right cable in the E-bay listing, and for all he said the power cable was included, it wasn't. Apparently he lost it in a warehouse move. OK, there things happn, but I still need to get one ot power up said plotter). -tony

Looking for AIX 3.2.5 boot media...

by derschjo＠mail.msu.edu

Got myself an IBM RS/6000 N40 laptop (made by Tadpole -- looks identical to the Sparcbook 3 externally) and I'm looking for OS media for it. I believe this runs AIX 3.2.5, and that's about it. Currently there's some version of AIX installed (the login prompt just says "3") but of course I don't know any usernames/passwords. (If there's a way to reset the password that doesn't require an AIX OS CD, that would be useful as well...) Thanks, Josh

CBM 8032 display CRT replacement

by starbase89＠gmail.com

Hey. I picked up a freebie CBM/PET 8032 system with dual disk drive and Z80 board a few weeks ago. It didn't power up. I put it on my workbench and opened "the hood" to suddenly find out that the CRT was not secure, because it hit my workbench neck first, and broke the clear glass at the end of the tube. I was wondering if it is possible to find a replacement tube. Could I somehow (on a really long shot) get a same sized CRT from a black&white TV to fit inside and work? Any advice or suggestions very appreciated. Thanks Joe Giliberti

Problems with IBM 5150 Power

by Watzman＠neo.rr.com

Re: "If you mean the power supply fan, then that means nothing in the 5150 (AC fan?)" That's not true. The fan is run on DC from one of the outputs (12 volts, I think, but it might be 5 volts). So a working fan is a good sign. But an entire output voltage can still be completely dead.
