VERY interesting phone call re: HP 9845. Can you help?

This only refers to BASIC programs, other files such as data files do not need a "detokenizer", but of course you need to know the structure of the data (which brings us back to reading the Basic programs that created them). As far as the Series 80 and the HP IPC (Integral PC), threre is a "detokenizer" that can be downloaded from: http://rocknroll.stanford.edu/~lharcke/programming/ (scroll down till you reach the section called "BASIC detokenizers for the HP Series 80 and Integral personal computers") I do not have access to HP-9845 Basic files, but the above programs may be able to read these files (hopefully without too much effort).

9-track tape drive to borrow? (Kent, UK)

by julesrichardsonuk＠yahoo.co.uk

Hi all, One of the guys working on restoring the EMAS OS for ICL mainframes as part of the Edinburgh computer history project asked me yesterday if we knew of anyone with a 9-track SCSI tape drive that he could borrow in order to read old OS tapes. Does anyone on the list based in the Kent area have one that he may be able to borrow or access? I get the impression he does have occasional access to a drive somewhere further afield, but being able to hook something directly up to his PC (or at least minimise travel) would greatly aid the restoration process. We're probably going to run EMAS on our ICL 2966 mainframe if the Edinburgh guys can get a working install for that platform together. We *may* have a drive that we could loan out, but I thought I'd ask in case someone closer to the guy has one sitting idle. See http://history.dcs.ed.ac.uk/history/EMAS for a bit of EMAS history, and http://pink-mouse-productions.com/icl/bob.htm for Bob's own pages (scroll down for a nice photo of the sort of thing we hope to recreate at Bletchley) cheers Jules

I've seen the exact same thing happen here at UPS in Orlando. They left the conveyor running until the packages piled up and JAMMED the conveyor.

In fact, they had turned it on because the people in the warehouse were on break and weren't taking the packages off the conveyor and the packages were piling up in the shipping office. The problem with UPS is that they expect the shippers to pack their packages to survive UPS's gross incompetence and mishandling! I called their national customer service office that same day and reported what I'd seen but they couldn't care less. I finally wised up and started shipping with FedEX and I NEVER use UPS any more.

OT (though not entirely) - old air compressor maintenance

Usually I use a hairdryer to get the bulk of the water >out from beneath ICs and then leave to sit in the hot water tank cupboard for >a week or so. Never had a problem with this, but it doubtless depends on the >quality of the water used. I'd definitely investigate using distilled water, especially for the final rinse. For the air cleaner- a room model might be good because it would (hopefully) keep some dust out of your machines. For cleaning, you can build a rudimentary "dust and fume hood" (although it doesn't work for fumes) out of a box and a vacuum. I've seen this used at small businesses to control dust. Just pop the computer in the box, turn on the vacuum, and blow away. For cleaning effectiveness, once you've used a tank compressor you'll never want anything else.

(Off-topic ?) Motorola HDS-200/Hitachi Development System (HAL-SJ ?)

by david_comley＠yahoo.com

Does anyone have knowledge of Motorola HDS-200 Hardware Development Systems ? I brought one home from Dayton bundled with a pair of HP64000 mainframes, manuals and emulation pods. The HDS-200 has a base unit, cables, emulation pods (68HC05 variants) and program cartridges. I am not sure whether I will do anything with it yet - just curious to know about these systems and their capabilities. Also in the carton: an (apparently unused) Hitachi development system of some sort, with a label marked 'HAL-SJ' and two boards marked H31MIX3. I'm guessing it's a 6301 or 6303 development system. Anyone with embedded systems or uP system development knowledge care to comment ? -Dave __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

New Altair32 Emulator Release/New Web site

by rcini＠optonline.net

All: Over the weekend I finalized the latest release of the Altair32 Emulator. This latest version - two years in development - wraps-up a string of changes to the emulation and adds some new emulated hardware: a Z80 CPU core, emulation of the Cromemco Dazzler, and, the best of all, support for the Altair32 Front Panel (another project of mine). The Altair32 Front Panel was introduced at VCFe two weeks ago and is a USB-based peripheral for the PC that enables one to interact with the Emulator as if at a real Altair. The Front Panel is a full-sized replica of the original Altair 8800 front panel. The dress panel I created can even be used as a replacement for a real 8800. The Front Panel should be ready for sale in the next 60 days after performing some last-minute optimizations to reduce manufacturing costs. As part of this, I have launched a new Web site specifically for the Altair32: http://www.altair32.com <http://www.altair32.com/> which also has a support bulletin board. In the Announcements section of the BBS, there is a short survey to gauge interest in the front panel. Of course, feel free to send me any questions. The picture on the index page of the site is the actual front panel (with the exception of the name plate strip, which I haven't made yet). Enjoy the emulator.

DECwriter Correspondent wanted, trade available

by sethm＠loomcom.com

Hi folks, I've been hunting high and low for a DECwriter Correspondent (LA12). These are smallish dot matrix printing terminals made by DEC in the mid 80s, designed to be portable. They take 9.5" x 11" pin-feed paper. Some models have acoustic couplers on the side. I'm interested in any working model. I have a Teletype Model 43 KSR I'd be very happy to trade for one. This is also a dot matrix printing terminal, upper and lower case, and takes 12" x 8.5" pin-feed paper. It's in good working condition. For information on the Teletype 43, see <http:// www.atariarchives.org/bcc3/showpage.php?page=287> and <http:// www.kekatos.com/teletype/gil/M43.htm>. Anyone have a DECwriter Correspondent they'd be willing to trade or sell? If so please let me know! -Seth Santa clara, CA

OT (though not entirely) - old air compressor maintenance

by chrism3667＠yahoo.com

well weve all seen how dusty the insides of computers get. I had been using a shop vac to blow out the crud, but its awkward and doesnt pack the same umph. So I picked up an oldie at a flea market. The motor is shot (easily replaceable) but before bolting a new one on, should I perform any maintenance? No obvious place to oil it. Pops or farts when I rotate the pulley by hand - is this a favorable sign of its condition? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

The Apollos might be the "Hybrid" 400 series, they might even be the pizzabox 425. Whilst not pure Apollos, they have the advantage of smaller size, DOMAIN/OS compatibility, and built-in, supported SCSI for disks (just not big ones). Whatever you do, don't throw out DOMAIN keyboards/mice please. RI isn't on my route home, otherwise I'd probably bite for something. The HPPA systems probably have the possiblity of running NeXTSTEP/HPPA, definitely the BSDish HP-UX variant. As you said, big, unless they are the tiny 9000/712s

You can fit a very basic 6.5.x install in under 500MB, and a reasonable install easily goes into less than 2GB.

Indys use single-ended narrow drives, but LVD drives *should* sense that they're in a single-ended system and operate in SE mode -- that's part of the standard. A couple of mine have LVD drives. Wide drives will also work providing you have the correct adapter -- you probably need one that terminates the upper 8 bits -- though you can still only uses unit numbers 1-7 (0 is the controller on SGIs). -- Pete Peter Turnbull Network Manager University of York

trs-80 model 4p saved...but have no s/w

by kelly＠catcorner.org

> I do not have a working 5.25 disk drive > other than the ones in this trs-80. How can I obtain some disks to > boot and test this system? Go to www.trs-80.com See if Ira will creat disks for you. If not, let me know which ones you need (based on the searchable list at Ira's site). I can make real disks from the images and mail them to you. You would have to cover postage and a small amount for each disk. I'm don't make a living doing this, but I can write just about any soft sectored format to 5.25, 3.5 and 8" media. I have not tested any DS/QD media in real life, but I know I can write it. All I want to be able to do is replace any disks I use. Kelly

Building new S100 floppy system

by rcini＠optonline.net

All: I have several random parts I'm going to pull together to build a "new" floppy system for my IMSAI. I have an SD Sales Versafloppy controller card (which used the FD1771B controller) and several 5.25" floppy drives (all soft sectored). The Versafloppy manual indicates that it will work with a Shugart SA400/450. When I look up the specs on the SA400, it indicates that the unformatted capacity is 109.6k and the formatted capacity is 81k. I didn't read the entire manual but this look like SSSD specs. I of course don't have any floppy drives like this but I have several original PC drives (TM-100 and others) and several 360k drives of various types. The question is this: can I use these later drives on this controller without problems? If there are problems, what might they be? Thanks.

International shipping question

by pat＠computer-refuge.org

So, I've got a rack of gear, which I need to ship to a guy in the Netherlands (who also happens to be a list member:). Has anyone done this before, and can you recommend any particular shipper? The only one who's actually sent me a quote back was FEDEX, which wanted $1500... which seems really high. The other ones I've filled out a quote request for didn't ever send me a quote back. Thanks, Pat -- Purdue University ITAP/RCAC --- http://www.rcac.purdue.edu/ The Computer Refuge --- http://computer-refuge.org

orange smoke from a CDC Magnetic Perepherals 94161-156

by compoobah＠valleyimplants.com

More fun from the CV 32- the CDC fixed SCSI drive sent up smoke signals today. Does anyone know what the first SMD coming off of the +12v lead is on these guys? it doesn't look like a fuse, and (in the past) orange smoke seems to mean tantalum caps.

Incorrect, 1771 recal worked with 77track 8" drives. The controller doesn't know or care. The software supplied with the versafloppy might have to be tweeked for 40 (or even 80) cylinders. thats a minor change. Overall with any effort a double density controller would be easy enough to find or build and would offer a more workable amount of storage. Allison

Building new S100 floppy system

by swtpc6800＠comcast.net

I have a 1977 SWPTC floppy disk system that uses the FD1771 controller. It came with Shugart SA400 drives and I upgraded to TM100. The stock controller card was single sided and it worked OK, You could use an existing latch on the SWTPC card to do side select. You can also use current production 3.5 inch drives with it. http://www.swtpc.com/mholley/35disk/Disk.htm Michael Holley www.swtpc.com/mholley > From: "Richard A.

OS/2 diskette image needed

by sethm＠loomcom.com

I've been slowly acquiring operating system media as I find it, trying to archive it where possible. Unfortunately, I've only just gotten around to trying to make backup images of my OS/2 2.1 installation diskettes. One of them is bad, and I can't get a good image from it. If anyone has this disk, and would be willing to send me an image (I've been using dd on FreeBSD to make byte-by-byte dumps), I would be very grateful! The disk I need is: IBM OS/2 2.1 Display Driver Diskette 2 61G0808 Version 2.1 (c) International Business Machines Yes, I do own the original box and disks. I just want to replace a disk that has failed. Thanks everyone, -Seth

ST-412 interface specification

It's > usually a lot simpler if you can ditch the old MFM controller and tie in a > modern IDE drive directly. Here is the situation. I have many older systems that only support the ST-412 standard drives. Most use a WD-1005HDO style controller to talk to the machine's bus. I also have several that use a custom controller to interface the system bus directly to ST-412 (without the WD-1005HDO). I'd like to continue using these systems, but I'm quickly running out of working drives. I do have the specifications for the system bus, but most of the software interface is not documented. I would need to dissasemble the executables to figure out what is going on. What I interpret what you said above to mean is that the interface between the controller card and the ST-412 drive is not simply a digital interface. It is acutally the MFM stream bi-directionally, and that the controller is what converts this to the system required digital stream, and the systems digital stream to the MFM stream. Is this essentially correct? I did find the OEM manual for the 412 on the bitsavers archive. I'll start reading it over tonight. Kelly

This sounds right to me. It would not be hard to make something in hardware to pull the clock and data back out. You'd then have (as I recall) the raw bytes for each sector (i.e. header + data + trailer). If you knew how the controller was programmed you could then easily find the data. It should also be reasonble to create the stream in the opposite direction. Some simple tests should prove it out. I have not done the math but it seems like a PIC or one of the low end ARM chips should be able to do this... worst case add a small CPLD to aid in the serial in/out. In other words, a ST-506 emulator. I'm pretty sure they exist as commercial products. (but for some reason I never see them ebay or other on-line auctions) ps: I found this for any Apple Lisa Profie users http://john.ccac.rwth-aachen.de:8000/patrick/idefile.htm -brad

DEC Pro 350: RAM ICs?

by sb＠thebackend.de

Hello everyone, I recently got a DEC PRO 350. It suffering from a lack of RAM since two of its three memory boards are defective (one of the small ones that plug into the mainboard and one that goes into the extension cage and seems to carry its own DRAM controller in logic). I first wanted to take a look at the small one but I can't even find any info on the ICs used: JAPAN 8304U 21-18470-01 There is a small logo that seems to indicate Hitachi as manufacturer [1]. Google refused to find anything on these chips. Does anyone know a few things about them? Pinout and timing would be a fair start... Thanks Sebastian [1] http://www.linksiden.dk/sub/ic_logo.htm

inverse assembler for hp 163x logic analyzer

by frustum＠pacbell.net

I tried searching the agilent web site, hoping they might have been kind to users of their obsolete equipment. Indeed, they were nice enough to post the manual for the 1631D, which is the model I have. They didn't provide any disk images for the Z80 inverse assembler, aka disassembler, software. Does anybody on the list know of a source of this software, or perhaps has it and is willing to make a dup? I have a Wang 2275 storage unit (hard disk + floppy) that fails to boot up, and it uses a Z80 as the controller. Fortunately, I have a second, working, 2275. By switching the disks between the units I have been able to image both hard drives, but it would be nice to get the 2nd unit going. Thanks.

HP 264x terminals

by jwest＠opensourceassociates.com

Hummm WHY did I offer to organize a group purchase? I'm asking myself that. Apparently the seller saw and/or heard about the words of caution that some people here posted, one was a lack of terminals being shipped, another was 'lets hold off on a bulk purchase till at least some terminals are shipped'. I'd like to throw in a few tidbits: 1) The seller contacted me and appears to feel I have caused a bit of a problem because my list had negative comments about him. I explained to him that anyone on the list is free to post their experiences, advice, etc. without me censoring. Talk to the people who expressed their concerns, not me. Nuff said. 2) I have been assured by the seller that the terminals are in fact on the way to the non-group purchase people. My views are below: My impression (from a few email exchanges only) is that this is likely an honest guy that basically fell into a boatload of units, and after the first few has found it to be a HUGE effort to carefully clean one up, test it, photograph it, pack it (well!) for shipping, etc. I suspect he's found this is far more effort (and probably mostly time) than he'd care to spend on it. I'm not sure he anticipated what packing a heavy unit like the 264x can be like. Just tossing it into a cardboard box won't do and he's aware of that. And he's got 50 of 'em. Thats a lot of time. I understand very well the thoughts and concerns expressed by the folks here, and I will defend your right to share them. However, what I was hoping to do for a bulk purchase (if it can be pulled off still) is to have someone in the vicinity pick them up. There's no cleaning/testing/shipping issues for him, and hopefully that would be reflected in the price. I don't have experience with this seller or inside knowledge that causes me to say this - but going from my gut only, I'd say give the guy a little slack for now. My scam meter isn't going off just yet. Form your own opinion. Jay West

-5V rail in a PC...

by lee＠geekdot.com

> Far as I know, things that needed -ve rails (like soundcards, serial > ports etc.) all used -12V... Can't say I've ever seen it used. I've just looked at a 200W PSU and the -5V rail is speced at 0.1A so you couldn't run much from it anyway. Also I've never bothered adding the -5V line to my VIC 20 ISA backplane, I've yet to find a card that uses it. The one card that does have +/-5V analogue supplies uses 78L05 and 79L05 regulators from the +/-12V rails. Lee.

Unknown IC

by cc＠corti-net.de

Hello, I have several unknown ICs from AMI, numbered 1315-P-2, a picture can be found on ftp://ftp.informatik.uni-stuttgart.de/pub/cm/ic/ami1315.jpg I think they came from ITT 3287 terminals (or ITT Courier, or Courier Terminal Systems). I have several boards from those terminals (all >from around 1976-77), they used the i8008 as processor (see picture). The unknown AMI IC is found on a board labelled CURSOR/BUFFER. I have boards with that IC as only LSI chip, or along with a Signetics 2650. So my question is, what is that AMI chip? Has anyone a datasheet? Oh, and I have some NatSemi 1409, 40 pins, as found on the TIMING board (which also contains 16 i1404 1kBit MOS shift registers as display memory), what is that? Christian

-5V rail in a PC...

by julesrichardsonuk＠yahoo.co.uk

Question on a local newsgroup about PC power supplies and whether the -5V rail is used any more, and it's prompted me to wonder what it was *ever* used for? Did the original IBM PC make use of -5V for any reason? Or is its inclusion maybe a hang-up from earlier machines that used three-rail memory devices? Far as I know, things that needed -ve rails (like soundcards, serial ports etc.) all used -12V... curious. cheers Jules

Not quite, what Chuck means is that most MFM drives after the ST506 have a slightly different interface, and should buffer the step pulses, and internally it will ramp up the step rate and ramp down again -- it can step faster once it gets going, than it can if it comes to a stop between pulses. This style of interface is often called an ST412 interface instead of ST506, because the ST412 was the first drive that supported it. Below is part of the Seagate data sheet for the ST251. You'll see the first line identifies it as an ST412-type interface rather than ST506. You can also see it can accept step pulses at quite short intervalsi, and should buffer them. If you give it a single pulse it will take 8ms to move one track, but if you feed it a series of pulses it should ramp its step rate up (and down when it's close to the destination cylinder) so that it can step the whole width of the disk in only 70ms.

Need help with large mini-computer near Jacksonville, FL

by sellam＠vintagetech.com

I've acquired a largish mini-computer near Jacksonville, Florida, and need help moving it. I plan to ship it to California via freight, and am hoping to make the trip out to Florida so I can pack it myself, but in the meantime I may have to get it moved from its current location to somewhere nearby. Is anyone near Jacksonville that can help me with this? A pickup truck and a couple sets of strong hands is all that's required to move them. They take up roughly 30 sqft of floor space (each unit is no more than 3x3 feet from what I can tell). I may even just go ahead and rent a small storage locker until I can get out there to prep the machines for shipping. Any help will be appreciated and rewarded with some goodies. Please reply to me directly <sellam at vintagetech.com>. Thanks! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Push button under the power cord cover on a VAX4000

by jplist＠kiwigeek.com

Hey folks; My recently acquired VAX has started acting up, seems it doesn't always like to power on. When I hit the main switch, the PSU light comes on (orange, by the switch) but the DC OK light does not come on, nor does the chassis power up. I've found that to get the PSU fully powered up I have to turn it off, and push that momentary switch button under the power socket on the PSU. On the VAX there's a sliding cover thing, which when down allows you to plug in the power cord. When you slide it up, it covers the power socket, but allows you access to the thumbscrew which holds the PSU in. When you lift this cover up to gain access to this screw, the cover pushes on some little button under there. What on earth does this button do, and why is it my VAX won't power on until I hit it? :P My thanks all; JP

Help in the netherlands?

by jwest＠classiccmp.org

I need to have some vintage cards picked up from a guy in the netherlands and mailed to me. He doesn't have a paypal account, and of course wants to be paid for shipping costs before he ships them. He doesn't know me from adam, and vice versa. So I was wondering if any list member would be willing to pick up the cards >from him (he's not charging anything for the cards), and ship them to me. I'll paypal you the funds to cover shipping. The guy is located around: 9824 PE Noordwijk The Netherlands If no one can help, I'll probably see about an international money order. There are probably about six cards, and in total probably not more than a few pounds. Thanks in advance... Jay

Unknown IC

by henk.gooijen＠oce.com

I vaguely remember the AY-1315 (not sure!!), but that 40-pin IC was a 8-bit data parallel to serial data bi-directional converter. A sort of a UART. To send serial data, you put the 8-bit data parallel in its 8 input pins, strobed an other pin and then the data with start- and stopbit came out of another pin :-) But, as said, memory is vague, but it might help ... - Henk. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Christian Corti > Sent: woensdag 17 mei 2006 11:42 > To: cctalk at classiccmp.org > Subject: Unknown IC > > Hello, > > I have several unknown ICs from AMI, numbered 1315-P-2, a > picture can be found on > ftp://ftp.informatik.uni-stuttgart.de/pub/cm/ic/ami1315.jpg > I think they came from ITT 3287 terminals (or ITT Courier, or > Courier Terminal Systems).

Inventorying a bunch of 8" disks

by cctalk＠catcorner.org

I have at least 1500 8" disks of various manufacture, density, and sides. Some are manufacturer's originals, some are well marked copies, others are marked in hand written Korean. Hundreds are marked in "user shorthand", and are probably quite un-interesting. Among the manufacturers I see are DEC, Altos, Microsoft, Digital Research, Pickles and Trout, Xerox and Tandy. There are also at least 30 CPMUG disks. I know at least one is a Scott Addams adventure disk for CP/M. I'd like to start inventorying them, dumping their content (using ImageDisk and the catweasel both), and trying to determine the "source" of the unknown disks. I know the usual warnings about these old disks: clean the drives, make sure they're not pinched in the sleeve, make sure there is no dust on the surface, etc. What other precautions should I take. Any and all _contructive_ advice welcome. Kelly

GRiD 1520 portable computer

by chd_1＠nktelco.net

I got one for $5 at a garage sale. Everything but the hard drive (CP3044 40MB) seems to work. I cracked it open and replaced the hard drive with one of about the same vintage and still no go. Further research indicates that it only works with 3 very specific drives, although I don't know what those are other than the CP3044. The two ROM sockets are empty. I think they could contain ROMs with a floppy disk image and allow the machine to boot without a disk. Anybody know if this is right? Do you need both sockets populated for an even/odd byte thing or is it one ROM making up a disk and the two sockets making two disks? This leads to an OT MSDOS question: Can MSDOS be told about a hard disk that the BIOS does not know about? You can probably see my line of thinking. Make a floppy that boots DOS and can talk to the new HD. Burn that onto a ROM and then make the machine boot from the ROM socket. Now what I would do with this 286-10 after that is unclear.

VCF East 3.0 wrap-up

by evan＠snarc.net

Man am I tired... but man was that fun! Got home from the VCF East 3.0 about 45 minutes ago. The one-day event was a major success for our MARCH club (Mid-Atlantic Retro Computing Hobbyists.) We had more than 100 people attend today, with another 30-40 if you count the exhibitors, speakers, volunteers, and guests. The fun started Friday morning when I arrived at the venue at 7:30 for setting up. The first exhibitor arrived by about 8:30, followed by a delivery of tables from the local party rental shop. Other exhibitors trickled in throughout the day and there were several last-minute tasks to complete. A major task: the all-hands-on-deck unloading experience when Mike Ross arrived with four IBM big-iron computers estimated at 1,000 pounds each. Mike also brought his friend Henk all the way from Holland. Eight of us went to dinner at 8:00 at the hotel bar. A funny thing -- two or three times during dinner we had other people tentatively approach us and say, "You must be the VCF guys"... LOL, what gave it away, was it our pocket protectors? We hung in the bar until 1-ish when Sellam finally arrived from the airport after a few delays. Saturday, we again started at 7:30. The remaining exhibitors arrived -- 18 in total -- and at 9:30 we opened to the public and prayed thay anyone would actually come. They sure did! By 10:00 our venue was so full you could hardly walk through the aisles. The five guest speakers also had full rooms. The most popular speakers were Steve Lukasik who ran ARPA in the 1970s, and David Ahl who founded Creative Computing magazine and who drew a standing-room-only crowd. (We video recorded the lectures and we'll try to make them available soon.) We closed at 6:00. Usually the attendence at these shows dies at the end, but even after 5:00 and with many people in the lecture room, our exhibits area was still busy. Highlights of the judging process were Bill Degnan winning several categories and the Best-of-Show award for his display of very rare Commodore B-series computers, and Mike Loewen taking the People's Choice award for his demonstration of how to connect vintage computers to new ones. This was my fourth VCF and my favorite part isn't the computers, it's seeing old friends, meeting old virtual friends for the first time, amd making new friends completely. But what made me most proud as a first-time organizer was hearing from so many people who drove great distances just because they thought our show was cool. Everyone seemed to leave happy -- even Andy Molloy whose Apple IIe power supply burned up in the morning and whose Canon Cat wouldn't turn on in the afternoon -- and people encouraged us to reach for even higher goals next year. Many people took pictures. Please post them soon!! Thanks to everyone who attended, exhibited, and volunteered. You made our hard work extremely worthwhile. - Evan

Sun 3004 CPU question

by compoobah＠valleyimplants.com

Still having problems with the Sun 3004 in my CV. A 3/110 board works fine in it, but the 3004 CPU continually cycles the 8->7->6->5->4->3->2->1 on the LEDs that Sun-3s do once on powerup. Has anyone seen this before to narrow down the possible things to look at? No, there is no output on the console (TTYA) port (checked the teminal and cabling with the /110 CPU to verify that it works)

Parity uses a single bit (in the case of 36-bit SIMMs, one bit per byte) to detect single-bit errors. It will tell you a byte is wrong, but won't tell you which bit, so it provides no correction capability. It will not detect two-bit errors. ECC stands for error correction code, and is a multi-bit arrangement capable of not only detecting errors but providing enough information to correct some of them. How much it detects and provides correction for, depends on how many bits and how they're organised. -- Pete Peter Turnbull Network Manager University of York

That's why on SGIs you sometimes see the error message "unrecoverable memory error" and relatively rarely see "Recoverable memory parity error corrected by CPU" :-) Most ECC memory uses more bits, and 36-bit memory is rarely described as ECC memory rather than parity memory. > There are also some machines (some sun4c and some EV5 Alphas) that need > 33 bit RAM. They use one parity bit per 32 bit word. True, though those will work with 36-bit memory as well -- they just ignore the extra bits. At least, that's true of the Suns; I've not actually tried it in Alphas but I don't see why it should ever matter. -- Pete Peter Turnbull Network Manager University of York
