I may have the wrong one. If it manages to download something (and thinks that it is successful) then that sounds like a non-fatal error. What are you downloading? Antonio

DEC parts code reference?

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Guys The most useful internal document we had when I was at DEC was the Price Book. It consisted of a 250 page line printer document reduced from 15" to A3 and bound into Book format. Every saleable item was in there. There must have been a database somewhere with every item DEC sold and its part number. Im unsure but there may well have been a corporate DEC 10 in the Mill. Somebody, somewhere must have a tape backup of the price list. (Now that would be a real find!!) We never knew how the part numbers got allocated either. However the product numbers like DLV11-J tended to be generated by the Product Line And the module numbers like M7786 were of engineering origin. It makes a little more sense if you know the internal structure of DEC (yes it did have one!)

I think I sent it to Manx but I'm not sure how easy it would be to make available over the net. (It's not the amount of data, it's more how to present it). Antonio

This could be solved by placing two 220pF ceramic capacitors over pins 7 and 11 of IC29 and IC37. This would fix the Beeb's booting problem, but unfortunately this would create a DRAM timing problem for Solidisk's 96k Sideways RAM expansion for the 32k SWR board. Took me (literally) years to figure that out! One of my 'when-i-have-time' things is experimenting with the capacitor's value to see if I can find the right value :-) Cheers, Eelco

DEC parts code reference?

by aek＠bitsavers.org

did DEC (or a third party) ever produce a reference listing of DEC "parts codes" against function (e.g. RK05 = removable disk, KL11 = serial interface etc.) -- Yes, the 'edited' and 'unedited' options/modules list(s) The April 1983 edited document can be found at http://bitsavers.org/pdf/dec/modules/modulesAndOptions/ There are separate catalogs for documentation, since they changed more often with software releases.

free for shipping: IMS 5000 IS system, from austin, tx, usa

by frustum＠pacbell.net

I have mentioned this system on this list a couple times before. The IMS 5000 IS is a S-100 based multiprocessor system running turbodos 1.3 (an extended multiprocessing CP/M clone). It is a very well built machine, clearly intended for office use. It has a single DSDD 96 tpi 5.25" floppy and a 10 MB hard disk (rodime ro 200). It boots off the hard drive, and couple months ago I spent some time and cracked the login/password file. The floppy disk appears to work (I can "dir" and get files off a floppy created on a PC using the teledisk program). The system doesn't have much on it in the way of development software, just some custom apps written for the dentist's office this came out of. As it is a CP/M system, though, you can use standard CP/M programs on it. The master system has a 8085-based intelligent terminal card, plus a master Z80 CPU and two slave Z80 CPUs. Each cpu has 64 KB of parity checked DRAM. I tried plugging in the slave to the master but I suspect things are not cabled right, as the slave terminal acts as if it is wired in parallel to the master terminal. I'd like to find a new home for this system. I simply don't have enough time to mess with it, and I don't have enough interest to make the time. Here are some a few cruddy pictures: http://home.pacbell.net/frustum/ims5000/ The only problem is that the local/remote key on the slave terminal keyboard is broken off (before I received it). The key still works; you can depress the stub of the plunger that is left, but luckily it is a key that normally doesn't need to be used. This system would be shipped from austin, tx 78737 at your expense. I recommend fedex ground, as it seems to be the least expensive of the majors for heavy items like this. It would be two boxes. I haven't weighed them, but I would guess 50 lbs and 30 lbs. They were shipped to me in their original boxes, and I'd ship them to you the same way. This means that there is a custom foam shell for each unit, but it also means that the original boxes are somewhat tattered and one has been reinforced, so don't wail that I've ruined everything by harming the original boxes. I'll give preference to anybody willing to come and pick them up, soon.

New DEC problem

When I had a KZQSA in a VAX 4000-500 I found that it would fail self-test if either port was left unterminated. I would not be surprised if an unterminated DSSI port had the same effect. Does it still boot if you make it boot manually (i.e. is the error fatal or does it just interfere with automatic booting?) Antonio

New pcb design for S-100 prototype board available

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Thanks for the positive feed back. Needless to say like all standards S100 had different versions. For example the Northstar Horizion had some active components on the mother board. However if we look at a basic passive (other than power) back plane. What are the potential problems? Firstly the connectors are they available? They had two rows of fifty connections. Spacing pin to pin .125in. Mother board was thicker than the usual 1/16 in for rigidity possibily 3/32 in. Card guides pretty standard but how high? Then the metalwork supporting the card guides. Possible Parts List 1. Double sided S100 motherboard (Say twelve slots) 2. Aluminium base plate drilled for backplane and card guide supports. 3. Twelve double sided 2x50 edge connectors. 4. Card guide support frame. 5. Twenty four card guides. 6. Nuts, bolts and screws etc. Rod Smallwood -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Dan Sent: 03 June 2007 12:59 To: On-Topic and Off-Topic Posts Subject: Re: New pcb design for S-100 prototype board available Rod, I see what you mean. I'm just starting off small right now since it's mainly a hobby. It's mostly to support the existing vintage computers out there. I really don't know what the demand there is for a new S-100 chassis. I suppose that might be a good kit to build with the right parts. I can look into this. =Dan [ My Corner of Cyberspace http://ragooman.home.comcast.net/ ] Rod Smallwood wrote: > Prototype boards are nice but whats really needed is an S100 card cage with back plane and PSU. > Its normal to build the foundations before the rest of the house!! > > Rod Smallwood > >

MODCOMP II Rescue Revisited...

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Well done that guy!! What you have done is both the spirit and the essence of classic computing. You are to be congratulated on both effort and persistence. "A shining light to lead others into the darkness of old computer restoration" I was at DEC (UK) in the 70's and Modcomp would pop up as competition >from time to time. Hasn't that front panel got DEC overtones? Is there a keyboard terminal or screen with it? Rod Smallwood DecCollector -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Lyle Bickley Sent: 05 June 2007 05:07 To: General Discussion: On-Topic Posts Only Subject: MODCOMP II Rescue Revisited... A number of you probably remember me "announcing" in Jan, 2007 that I had rescued a MODCOMP II/12 from a lab here in Silicon Valley. The link for that is below (sorry, it's slow - the pictures are large). http://bickleywest.com/modcomp.htm After a lot of work cleaning up both the CPU and I/O chassis I began checking out the system. It turned out that the I/O chassis was in pretty bad shape. I went back to the lab facility where I found the MODCOMP II - looked through several more buildings - and found another lone MODCOMP II I/O chassis. I went through the "salvage" process again - and finally picked it up about a month ago. It was in a lot better shape than the original I/O unit. And the really great news - it was an identical configuration to my original I/O chassis. After cleaning it up, doing all the usual capacitor, power supply checking - I powered it up - and everything "looked" good - and no bad "cooking" smells ;-) I cabled up the CPU and I/O unit, powered 'em up - and to my amazement the front panel controls seemed to work O.K. I then did the usual hand memory tests - and core memory worked O.K. every location I tested. I then wrote a bunch of small diagnostics (in machine code) - and found that I/O was not easy to code - but I did enough to check that the console in/out ports worked O.K. Today I loaded diagnostic monitors, and diags - and most of the system - including I/O is working! The really good news is that all 64K (words) of core memory passed the long manufacturing memory diagnostic - which even tests for "hot cores" failing. It's been months in the making this critter come alive - but it sure feels great when the diagnostics tell you that you are on the right track :-) Cheers, Lyle -- Lyle Bickley Bickley Consulting West Inc.

Vintage Mac II NuBus video card identification

by lynchaj＠yahoo.com

Hi, I recently came into possession of a vintage video card apparently for a NuBus Mac II. Can anyone help identify it? I do not have a Mac so I cannot plug it into anything. It is a two card video board from Rasterops with an apparent NuBus connector. The boards both say "RASTEROPS CORP MADE IN U.S.A." The main board says "(C) 1987" and the daughterboard says "(C) 1988" The back of the main card says "P.C.B. 0001-0013 REV. XB1" The back of the daughter card says "P.C.B. 0001-0019 REV. 01" There are no visible FCC IDs anywhere on the card but may be buried under the circuitry. I have not disassembled the card. Here are some photos of the card. ?Any information would be appreciated, even confirming what Mac II NuBus video card this model is NOT would be helpful. ?Based on an earlier post on "comp.sys.mac.graphics" with responses and some clues, I suspect it to be a RasterOps 24L card cannot confirm it. http://www.geocities.com/lynchaj/img_3023.jpg http://www.geocities.com/lynchaj/img_3024.jpg http://www.geocities.com/lynchaj/img_3025.jpg Thanks in advance!

New pcb design for S-100 prototype board available

by marvin＠west.net

I also use PCBExpress for the small boards I make (transmitters and offset attenuators for transmitter hunting), and they are quick and inexpensive. I'm told by a friend of mine that a place in (I think) Bulgeria makes good quality boards at a better price (and are ROHS compliant) but I haven't tried them. Sidelight - The guy who started PCBExpress lives in Santa Barbara and used to work for Polymorphic Systems. One of the things *I* am interested in is finding out is if a "MicroAltair" was ever made by Polymorphic or if it was a preliminary announcement that got quashed by MITS. That was why the reason for the conversation I had with him (still don't know, but got another lead to find out.) Marvin, KE6HTS > but the "bare bones" boards. I use them for prototypes too.

Prefer blinkenlights over SVGA? Yearn for the days of input via toggle switches and paper tape? Or just want to play some Pac-Man? Then check out the Vintage Computer Festival East 4.0, June 9-10, at the InfoAge Science Center in Wall, New Jersey. This year's event is again hosted by MARCH -- the Mid-Atlantic Retro Computing Hobbyists. The Vintage Computer Festival began in 1997 in Silicon Valley, migrated eastward in 2001, and became a MARCH event in 2006. So what is a VCF? Imagine an antique car show where every owner let you test-drive his car, and where Henry Ford gave a lecture and signed autographs! It sounds unreal, but that's what happens with vintage computer technology at every edition of the VCF. This year's edition of the VCF East will feature 20 exhibits of computer technology from the 1940s to 1980s. Visitors will have the opportunity to use an IBM punch-card machine, witness a legendary Digital Equipment Corp. PDP-8 minicomputer in action, and experience all the top brands of 1970s microcomputers from companies like Apple, Commodore, and many others. Older S-100 kit computers, single-board computers, portables, and even analog and prehistoric computer technology will be demonstrated. On the extremes, we have one exhibitor preparing to show an authentic NASA Apollo flight computer, and another who'll display the most classic videogame console ever -- Atari -- play it 'til you drop! Read the full exhibitor list at http://www.vintage.org/2007/east/exhibit.php. If that's not enough, then listen to some of our guest speakers. The highlight this year will be a 30th anniversary panel in honor of Commodore, which was headquartered nearby in West Chester, Pennsylvania. The panel's star is Chuck Peddle, inventor of the famous MOS Technology 6502 chip, used in a wide variety of classic single-board computers and in microcomputers such as the Commodore PET and the Apple II. Peddle will join us via live videoconference, in which he promises to share previously untold stories, after which he'll answer audience questions. Commodore engineers appearing live at our show will include Bil Herd, Bob Russell, and Dave Haynie. We'll even have a birthday cake featuring the famous Commodore "Chickenhead" logo. Other speakers this year include Herb "Dr. S-100" Johnson, who'll explain the history of the CP/M operating system; Bill Degnan and Sellam Ismail; who together will give a crash-course in vintage computer discovery and restoration; and others to be announced. In addition, Ismail will give a second talk, but the topic is secret! You'll have to be there to find out what he plans. Yet another highlight of the VCF East 4.0 will be our new VCF Theatre, organized by acclaimed technology filmmaker Jason Scott. His films include "BBS: The Documentary" and the upcoming "Get Lamp" about text-adventure games. At the VCF Theatre, he'll be screening vintage computer-themed movies all weekend long in the afternoons. New this year is the donate-to-sell booth. Here, everyone is welcome to donate vintage computing items, with all proceeds to help MARCH build its computer museum. Our museum directly benefits future generations, so do your part and give something to this wonderful non-profit cause! (We request that any unsold items be re-claimed before you leave the VCF.) Did we mention the prizes? We'll have t-shirts, vintage computer replica kits, books, and maybe a surprise or two. All you have to do to win is show up, and be there when we announce winners each day. Finally, should your historic technology interest extend beyond just computers, then you've come to the right place. Our venue at the InfoAge Science Center is historic in itself. The facility began life in 1912 as an R&D center for Britain's Marconi Wireless Telegraph Co., and then spent several decades as Camp Evans, a top-secret laboratory of the U.S. military. RADAR that first spotted airplanes over Pearl Harbor and mankind's first radio signal to the moon were invented here, along with numerous other achievements. Today, the center is on the National Register of Historic Places and is a Black History Site. It's also home to the National Broadcasters Hall of Fame and an assortment of non-profit clubs all related to the history of technology, with a local focus. Driving directions, lodging information, exhibit details and more are posted at www.vintage.org/2007/east/. * For more information about MARCH, visit www.midatlanticretro.org * For more information about the InfoAge Science Center, visit www.infoage.org * For more information about VintageTech, visit www.vintagetech.com General questions?

MODCOMP II Rescue Revisited...

by lbickley＠bickleywest.com

A number of you probably remember me "announcing" in Jan, 2007 that I had rescued a MODCOMP II/12 from a lab here in Silicon Valley. The link for that is below (sorry, it's slow - the pictures are large). http://bickleywest.com/modcomp.htm After a lot of work cleaning up both the CPU and I/O chassis I began checking out the system. It turned out that the I/O chassis was in pretty bad shape. I went back to the lab facility where I found the MODCOMP II - looked through several more buildings - and found another lone MODCOMP II I/O chassis. I went through the "salvage" process again - and finally picked it up about a month ago. It was in a lot better shape than the original I/O unit. And the really great news - it was an identical configuration to my original I/O chassis. After cleaning it up, doing all the usual capacitor, power supply checking - I powered it up - and everything "looked" good - and no bad "cooking" smells ;-) I cabled up the CPU and I/O unit, powered 'em up - and to my amazement the front panel controls seemed to work O.K. I then did the usual hand memory tests - and core memory worked O.K. every location I tested. I then wrote a bunch of small diagnostics (in machine code) - and found that I/O was not easy to code - but I did enough to check that the console in/out ports worked O.K. Today I loaded diagnostic monitors, and diags - and most of the system - including I/O is working! The really good news is that all 64K (words) of core memory passed the long manufacturing memory diagnostic - which even tests for "hot cores" failing. It's been months in the making this critter come alive - but it sure feels great when the diagnostics tell you that you are on the right track :-) Cheers, Lyle -- Lyle Bickley Bickley Consulting West Inc.

New pcb design for S-100 prototype board available

by aek＠bitsavers.org

If you are doing a design with on-board regulators in the 21st century, why not use integrated switching rather than linear regulators? Heat dissipation will be MUCH lower if you do this.

ebay "unpaid item strike" -- what's the consequence?

by marvin＠rain.org

If you are listed as the buyer, you should still be able to leave appropriate feedback. Just be aware that the ebay system supports retalitory feedback by the other party even though Ebay officially disallows it (they lie consistantly.) Generally, you can avoid retalitory feedback by just not leaving feedback. The other way is to "snipe" the feedback at the 60 day limit of when you can leave feedback (or so I've been told.) > From: Richard > > Well the seller is still being an asshole and refusing to answer a > simple question about how the item would be shipped. He says he's > going to relist it and stop wasting his time with me because I'm > "playing games". Some people love to do things the hard way! He's > wasted much more time dicking around trying to make a dispute out of > this instead of just answering the question I posed to him after the > sale completed.

How do I get my money back? (from dishonest ebay seller)

by vax9000＠gmail.com

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=260115466844 I sent her $50 post office money order, including some extras for better packaging. But she did not answer emails, and she did not send me anything. She cheated some 10+ other people in the same period of time. I know, she had negative feedback back in 2002 before these recent auctions. But her auctions did not look like fraud when I bid. I heard that it is classified as mail fraud. If I report to the mail office, at least they are going to send her a letter to threaten her. Does anybody here have such experience? How do I proceed? Help please. vax, 9000

Repairing the damage.

by RodSmallwood＠mail.ediconsulting.co.uk

Hi I probably failed to make my self clear. 1. Yes MOP is part of a whole heap of programs that go to make up DECNET 2. MOP stands for Maintenance Operations Protocol and that what is was for. 3 It pre dates DECnet (Well at lest internally in DEC) 4. It can be run on its own. 5. It's a much lower level system than LAT or LAVC that run at the application (top) level of the OSI Model 6. It runs at the network level (Layer 3) in the seven layer OSI model 7. Of course there is a physical network and enough of a driver in the firmware in the target VAX to exchange frames with the MOP running in the boot server. (I found a list of them) So in that sense it is running a subset of Decnet. However let's not confuse a low level maintenance tool with all the good stuff the full version of Decnet gives you. 8. Its twenty-five years since I was a product manager in DEC SWS. No wonder I'm a bit hazy on this stuff!

I'm not sure why I'm responding to this troll, but I can't resist. The server must be running a MOP listener. That's the protocol that the client uses when you boot the ethernet device. MOP is a DECnet protocol. For many versions of VMS, the way you get a MOP listener is to install DECnet. For VMS 7.0 and later, there's a separate MOP listener that provides just that part of DECnet. >There's no Decnet or any other normal network involved. Crap. You MUST have a network to run a Local Area VAXcluster. You know, a *Local Area Network*? LAVC booting uses DECnet to boot. You can't make any of this work without a LAN, without DECnet. I suppose you'll keep flailing around hoping that something will work, blaming others for your mistakes. Enjoy yourself. >I am also >beginning to suspect that the whole cluster thing is another GRH (Giant >Red Herring) Huh? Nope, if you followed the very detailed directions you've been given, you could diskless boot the server. You could then try to get a disk set up and booted. Not a red herring at all. >Whats actually happening is an old diagnostic tool is being used to >download and run a program on a remote system to exclude the disk >drives from the test. LANCP is not an "old diagnostic tool" it's actually fairly recent. Using CLUSTER_CONFIG as you're supposed to will use it to set up the client download. Did you try that? Probably not. -Rick

3174 Terminal Controller

by ian_primus＠yahoo.com

Well, this has been one of those ideas that has been at the back of my mind for a long time - I would like to interface one of these IBM terminals I have around the house to something. Anything. I was thinking about an emulated mainframe on Hercules or something. But the thing that brings this to the foreground in my thoughts is that today I had to troubleshoot a 3174-51R at a customer's site. This thing is connected, via a rather unusual cable, to a Cisco 2500 series router, so that means the 25 pin connector on the back must be some form of X.25 or something like that. I know that the fellow at corestore.org has been able to get a real IBM terminal to telnet into an emulated system via a terminal controller with built in ethernet (although I have never seen one). Anyone done this before? What do I need to hunt for? I now have one piece of the puzzle that I was never able to find before - the manual for the 3174-51R. Now the terminal controller's operation can be deciphered. But, of course, I don't have the 3174. -Ian

This is usually SDLC that is source-route-bridged over IP. S390 Open System Adapters (or whatever they called the ethernet/ip adapters for old S390's) could talk SRB/IP. It's been 13 years since I played with these. So, on the "cluster controller" (3174) end you have stock SDLC via synchronous serial on either RS232 or V.35. On the server end you'll need to get hercules to emulate an OSA.

I remember back when 386's were over our "capital expense" limit ($1000) at work, we would piece together 386's for the engineers to get them the best machines. We were buying Conner 80MB drives at the time, so we built this guy a machine with a Conner-80MB in it, and a few months later he was running low on space and wanted another drive, so we bought *another* (same model) Conner-80MB. No matter what I tried, they would not work together either way around as master/slave. Looking at the model#, one was "rev-A" and one was "rev-B". We wound up throwing a Maxtor 80MB in with it - with *either* Conner drive and a Maxtor, it worked fine. Found it quite humorous that two drives from the same manufacturer wouldn't work together, but both worked fine with a competitors drive. ************************************** See what's free at http://www.aol.com.

digital camera capabilities

by tim.walls＠snowgoons.com

Tony Duell wrote... > The right way to get better depth of field for oblique shots is to tilt > the lens (!). > [...] > The problem is that no digital camera has a tilting front. In the interests of completeness, I should say that this isn't strictly speaking true. Canon make EOS mount tilt/shift lenses, which will work on any of their digital SLRs (three of them, 24, 45 and 90mm IIRC.) In fact, their APS-C sensor DSLRs are in many ways ideal - the smaller-than-35mm sensor size means you're unlikely to see any vignetting even at extreme ends of the available movements. (For the uninitiated, a lens intended for tilt/shift, such as the TS-E lenses or anything made for a technical/view camera, needs to project an image circle significantly larger than the imaging plane (film/sensor), to allow for moving the projected image around as you move the lens. The extreme ends of the movements on the tilt/shift FD mount lens I use on my film camera are marked in red - this indicates you're going to start seeing vignetting if you tilt/shift this far because the image circle no longer covers the whole film area. Because most (not all) digital SLRs use smaller APS size sensors (~25mm longest edge IIRC rather than ~36) this is less of a problem.) That said, the Canon TS-E lenses are considered 'speciality' lenses and priced accordingly; unless you're going to make a living out of architectural photography not really a serious recommendation. My recommendation for a cheap digital starter kit for doing what you want would be the bottom of the range Canon digtal SLR (EOS 400D in Europe, 'Digital Rebel XTi' I think in USA - identical camera, but US market apparently demands a 'cool' name like 'Rebel'.) Buy it body-only, and buy the Canon EF-S 60mm f/2.8 Macro lens as well. The EF-S is a beautiful lens at a very reasonable price; top-notch quality, the effective focal length given the smaller sensor in a DSLR is around 90mm, which is pretty reasonable for what you're looking to do, and most importantly it can do true 1:1 macro for when you want the photos of individual chips on that motherboard. It's also compatible with the Canon ringlight flash if you find yourself doing a lot of macro. The only caveat is that being an EF-S, it's not compatible with full-frame DSLRs or film SLRs (EF-S lenses take advantage of the smaller sensor & mirror size in DSLRs to extend the optics further back into the camera; if you could mount them on a film cam (which you can't, the mount prevents it,) the back of the lens would smash the mirror. Oh, that reminds me, in a conversation a while ago possible sources of weak acid solutions were being pondered. I meant to mention then, but it didn't seem worth an entire post - photographic stop bath is a weak acid solution, and readily available (in the UK, your high street Jessops still stocks most photographic chemistry, for the timebeing at least.) 'Normal' stop bath is acetic acid based I believe, you can also buy odourless (or more accurately 'less obnoxious odour') stop bath which is usually citric acid based.

11/04 or 11/34 PSU free for collection (UK)

by pete＠dunnington.plus.com

I'm having a bit of a clear-out, in order to make enough room to work in :-) The first item I've found that I don't want is the power supply from an 11/04 or 11/34, DEC part no. 70-13323-00. This is the big black box that goes on the back of the BA11 enclosure, and includes the two fans, the cables, etc, but not the power regulator bricks (it has space for four). It was in working order last time I checked. It's very heavy, so pickup from York only (unless you really want to spend a fortune on carriage). -- Pete Peter Turnbull Network Manager University of York

Properly "classic" digital cameras (and imaging) (was Re: enough already (was: digital camera capabilities))

On 5/30/07, Gordon JC Pearce <gordon at gjcp.net> wrote: > I have a digital camera that is now (and in fact, as of last friday) 10 > years old ;-) Mine is quite safely "over the line" - my first digital camera was a QuickTake 150 http://manuals.info.apple.com/Apple_Support_Area/Manuals/cameras/0306677Qck… I picked it up at the Dayton Computerfest (same place as the Hamfest, but was in March or August of each year until they stopped having it a little while back). I first encountered one in 1995/1996, then bought one for myself for a whopping $35 a few years later when I had the chance. All I'm missing is the closeup lens. > The image quality is *definitely* not as good as an SLR, or even a > pointy clicky Instamatic. Great for grainy lo-fi shots though. With 1MB of fixed, on-board, Flash ROM, and no media socket, the QT150 holds 16 pictures in "bad" mode, or 32 pictures in "worse" mode. It's always 640x480, which, by itself, isn't the worst thing in the world. The problem is the amount of lossy compression it needs to fit 16 pictures into 1MB translates to "a lot". The other significant problem I see with this camera is that because Apple bundled some 3rd-party software with it, they never made the software available for download. The pictures are "QuickTime Compressed PICTs", meaning that the outer wrapper is a standard Mac PICT file, but the payload can only be untangled by an Apple QT library (I tried many unsuccessful workarounds). If you don't have the QT150 install disks, I don't know that you can load any other package to gain them. OTOH, once you have loaded that library, all apps on the machine (Photoshop, ImageViewer...) can manipulate the pictures. I'd hold this camera up as an example of a) an evolutionary dead-end, and b) the fact that Apple wasn't always spot-on-the-mark. In its era, it was a passable camera - one button to take a picture (no manual settings beyond a timer or compression factor), but all the other offerings of the day, and even Apple's QuickTake 200 (a rebadged Fuji DS-7 if my research is correct) had removable storage, allowing one to effectively ignore memory limitations to the extent of one's budget. Being a fixed-focus camera, it's terrible for close-in shots. Your choices are to position the object a few feet away so that it's in focus (and perhaps too small to be clear), or to snap on a fixed magnifier lens and squint through the eyepiece to attempt to focus closer in. At the place I first encountered the QuickTake 150, we never could get sharp pictures with the close-up lens. I used the QuickTake 150 more than any other digital camera from 1995 through 2003 (when I upgraded to a DSLR). If you ever get the chance to play with one, I can recommend it, but only to see how far digital cameras have come in the past 10 years (it was discontinued in 1997). The horrible lossy compression makes it nearly unusable for any sort of "busy" subject matter. -ethan

S-100 Systems

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Having read all the correspondence on S-100 systems there are three possibilities. 1. Restoration 2. Reproduction or Replica 3. Reinvention Restoration In a restoration you are trying to get the system back to what it was when first made. So when possible you would use components made at the same time the system was. Can be done and is done. Does need a knowledge of older electronics and good parts sources. Reproduction or Replica Here you are attempting to make a system as close to the original design as possible but using recently manufactured versions of the original components. Where do you draw the line? Well FWIW my take on this is if it fits in the original holes and performs the same function or is the same value then the fact that it may not look exactly the same as the original is OK. Makes a nice kit project. My preference would be a Northstar Horizon. (wood effect box and all) As far as I know nobody owns the rights and the company was not sold it just folded up. Reinvention Say a copy of old S-100 system on the outside only That means the box and front panel are new but as the original. Inside,there are new electronics simulating the old system. Good route for the run the old software fans. Rod Smallwood

ebay "unpaid item strike" -- what's the consequence?

by legalize＠xmission.com

I purchased a Qume QVT-101 terminal on ebay. I asked the seller how it would be packed for shipment. They didn't respond. I asked again. They didn't respond. I asked a third time, they responded "It will be shipped the usual way". I responded that since I've never purchased anything from them before that this doesn't answer my questions about how the item will be shipped. I don't want to receive damaged terminals from ebay anymore. I explained this to the seller. Instead of answering my simple question and reassuring me that it will be properly shippe, they just immediately open an ebay dispute on me and then have turned it into an "unpaid item strike". I've appealed the strike with ebay, but I doubt I'll get any love from them. So my question is -- what does this mean for me? Is it just listed as harsh negative feedback? -- "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/>

Repairing the damage.

by RodSmallwood＠mail.ediconsulting.co.uk

I am beginning to wonder if everybody is talking and nobody is listening. ************************************************************************ *************** * The target machine is not running anything except low level firmware !!! * * No DECNet No Tcpip No VMS - Nothing !!!! (It can't-disk drives inoperable) * ************************************************************************ *************** However after wading around in sea of online manuals I think am beginning to find out the things they don't tell you. Given that there has to be some form of communication between the Boot server and the target. Then what's left is this MOP thing. As you can specify that the boot device is the ethernet adaptor (EZA0: in this case) when you try to boot from the target system it must be sending out some kind of request packet with an ID attached. It can't be a node name or an IP address. There's no way tell it what they are!! What it does know, is its MAC address which is hard encoded into the interface. The server has to respond to the request (Remember No Decnet and No Tcpip available) somehow or other. So what is it that runs on the server does not use Decnet or Tcpip and can load images into the target machine? We can rule out @SYS$MANAGER:CLUSTER_CONFIG_LAN which expects Decnet and screw's up TCPWARE. I'm out of ideas at this point.

You can't be serious...? Cluster-booting of VAXen is something that has been happening in thousands of multiple-VAX installations for two decades. I did it myself when I was still a teenager. It is nothing unusual. I am sorry to hear that the attempt hosed your machine. -Dave -- Dave McGuire Port Charlotte, FL

Cluster Booting - What they dont tell you.

by RodSmallwood＠mail.ediconsulting.co.uk

Hi As with many things the answer is very simple. The key is a program called LANCP invoked as $MCR LANCP on the boot server. It allows you to associate a name say VAX300 with a MAC address and add it to a database. It also allows you to set the name of the file to download and the root of the system. So far so good.... Now for the other half of the puzzle. How does the boot server listen for requests? Well there's an executable program call LANACP that is invoked by running LAN$STARTUP.COM Once running it services boot requests from across the network. It uses the data from the data base maintained by LANCP. It gives progress messages when a Node tries to boot. Once you have done that then, from the target system type >>>Boot EZA0: (ie the ethernet device on the target system) Lo and behold it downloads the file. It may well be the case that clusters use this system to boot satellite systems but you do not have to be a cluster to use it. We are not trying to make a cluster here. We are trying to boot a system that has empty disk drives. When I worked at DEC we were always warned that whilst .com files were very powerful things never to use them unless we understood what every line did. Further more each command line should be tested by entering it manually. I can now download a file to a target system just by typing Boot EZA0 at the >>> prompt. No Decnet, No Tcpip, No Clusters. The firmware on a VAX is independent of operating systems be they System or Network.

Never run a .COM file before looking to see what it does. cluster_config*_LAN*.com? You aren't meant to run that are you? At least, I've never done it that way. I've just attached a sample of invoking @SYS$MANAGER:CLUSTER_CONFIG.COM on my VAX. If you never at least entered the MAC address of your satellite VAX then you definitely ran the wrong procedure! I thought you had V6.2 - the LANACP stuff popped in V7 sometime, for those who didn't want to install DECnet-Plus. I would expect the procedure (if you run the right one) to do the right thing (but I don't have a VAX with that config around to check right now). One other thing: > DEFINE NODE VAX300/ADDRESS=08-00-2B-18-BB-D0/FILE=APB_061.EXE Before you go to far down this path, this is used to boot an Alpha from an InfoServer (or at least that's what I think it is, my infoserver isn't in use right now). So I don't think this is what you want. CLUSTER_CONFIG.COM should as a few questions, set a bunch of stuff up and then wait for you to boot your VAX 4000-300. There's no way that you are expected to delve this deep into this stuff if you run the right procedure.

Repairing the damage.

by RodSmallwood＠mail.ediconsulting.co.uk

Your server (the VAX 4000-200) does have to be running DECnet. Er no it doesn't and isn't. I attended a 1976 DEC engineering meeting where this was discussed. It just my personal memory has a long access time. Download and run was around long before Decnet was thought of. There's no Decnet or any other normal network involved. I am also beginning to suspect that the whole cluster thing is another GRH (Giant Red Herring) Whats actually happening is an old diagnostic tool is being used to download and run a program on a remote system to exclude the disk drives from the test.

Your server (the VAX 4000-200) does have to be running DECnet. MOP is not technically part of DECnet but the MOP-handling software is started as part of DECnet. (Actually, there is a another way with more recent versions of OpenVMS, using the LANACP stuff but I assume you haven't done this). Maybe I've missed a message or to, but does your VAX 4000-200 have DECnet (either Phase IV or DECnet-Plus) installed and running? It would be very unusual if it didn't, but it is possible to install without it. Antonio arcarlini at iee.org

The 7805/lm309/lm323 reguire only 8V. All of the older 3 terminal regulators must have a 2.7V differential to regulate. The yabut, most of the S100 supplies were so poorly filtered that at any load the ripple voltage was excessive and didn't meet the minimum of 8V at the bottom of the ripple trough. A good example of that was the early Altair 8800 before MITS upgraded the transformer. With a 8A load the DC votage sat at 8.3V but the lowest voltage was 7.1V due to the AC ripple. Needless to say that ripple fould it's way to the 5V rail as the regualtor didn't have enough head room to regulate.

************************************** Episode 1 *********************************** This is as far as I got to this morning: I am beginning to wonder if everybody is talking and nobody is listening. ************************************************************************ *************** * The target machine is not running anything except low level firmware !!! * * No DECNet No Tcpip No VMS - Nothing !!!! (It can't-disk drives inoperable) * ************************************************************************ *************** However after wading around in sea of online manuals I think am beginning to find out the things they don't tell you. Given that there has to be some form of communication between the Boot server and the target. Then what's left is this MOP thing. As you can specify that the boot device is the ethernet adaptor (EZA0: in this case) when you try to boot from the target system it must be sending out some kind of request packet with an ID attached. It can't be a node name or an IP address. There's no way tell it what they are!! What it does know, is its MAC address which is hard encoded into the interface. The server has to respond to the request (Remember No Decnet and No Tcpip available) somehow or other. So what is it that runs on the server does not use Decnet or Tcpip and can load images into the target machine? We can rule out @SYS$MANAGER:CLUSTER_CONFIG_LAN which expects Decnet and screw's up TCPWARE. I'm out of ideas at this point. Rod Smallwood ************************************** Episode 2 *********************************** More wading around in on line manuals ... Then some light .... The key is a program called LANCP invoked as $MCR LANCP It allows you to associate a name say VAX300 with a MAC address and add it to a database. To do this it uses the DEFINE command. DEFINE NODE VAX300/ADDRESS=08-00-2B-18-BB-D0/FILE=APB_061.EXE This refered to as a NODE. Now the Boot server knows about the target machine and its MAC Address. So far so good.... Now for the other half of the puzzle. How does the boot server listen for requests. Well there's an executable program call LANACP that is invoked by running LAN$STARTUP.COM Once running it services boot requests from across the network. It uses the data from the data base maintained by LANCP. It gives progress messages when a Node tries to boot. ... and of course it works up to the point where it does not recognise the file name to down load (I have not found out what thats called yet) So.. 1. Hands up all of you who knew this and did not mention it. - Shame on you!!! 2. Hands up all of you that did not know this - Well, now you do!! 3. For MOP read LANACP. 4. Whats the name of the file to be downloaded from boot server to target to get VMS running on the target.? Lessons 1. Never run a .COM file before looking to see what it does. 2. Try and work out what needs to happen first. Rod Smallwood

New pcb design for S-100 prototype board available

FYI: even the 2102LP parts were around 50mA each (512 *.05=25.6W) and the more common parts were around 80-100mA. Add regulators and that could easily total 40-60W of heat. Add a few IO, Floppy card and CPU and now your cooking. If the drives are in the box add fans accoringly. Dont forget the average 8V bus PSU was (in a decent box) rated to deliver that voltage at 25A (125W of 5V alone). Some boxes like the Compupro and Intergrand had CVCC transformers that typically ran hot as well. So the average S100 grate needed to move between 100 for a small system to as much as 500W of heat. >True, but with the advent modern chips like CMOS I see that >power consumption less of a problem.

A[2]=1. Any other order would not make sense. Algebraic equations do not read left to right. This causes a sense of ambiguity but shouldn't. Where it wouldn't be clear as to the result would be for the case: A = (5*N++) + (6*N++) But that only goes to show how poor this type of notation is for defining sequence of execution. This is why I still think RPN notation is much better for computer programming. This need not be a stack language like Forth. It is concise. Events happen left to right. No special rules. It isn't familar to what you learned in grade school but doesn't take long to grasp.

Repairing the damage.

by compoobah＠valleyimplants.com

Aren't VAXen similar enough to where you could drop the -300's disk in the -200, install VMS (or dup from the -200's system disk), reinstall the disk in the -300, key in the -300's licenses and AUTOGEN? I don't know as much about VMS as I'd like to, but I've had the disk from a 3100/76 up on a 4000/200 to test functionality, and is seemed to work fine.

New pcb design for S-100 prototype board available

by ragooman＠comcast.net

I've been working on a pcb design for a S-100 prototype board. I noticed a few people on the forums asking about this. I decided to make this since this is a big hobby of mine too(member-MARCH club). I based this design on a old prototype board I kept back from the S-100 days. It's made by Electronic Control Technology. Here's a link to the picture http://pghvintage.home.comcast.net/p...otypeboard.jpg <http://pghvintage.home.comcast.net/pics/S-100/s-100_prototypeboard.jpg> There were several different styles made before--each with their own advantages. This prototype board(in pic) has the rows in a vertical pattern to allow 300mil and 600mil DIP packages. It also accommodates 2 voltage regulators. Then there were some which only had a grid of solder pads to allow any arrangement of 300mil and 600mil DIP packages. I like to ask everyone what their preference might be in the arrangement of the solder pads, eg: vertical rows, horizontal rows, grid, etc. If I get enough feedback, I can include 2 different styles. It's not much work to alter the design. I have a panel setup to include 2 pcb designs at the moment, and it can be any 2 kinds of S-100 designs. In the future, I like to setup a bigger panel to include several more S-100 designs. Since this is mainly a hobby for me, I thought I might help out and offer this service. I'm designing this from my home workshop and intend to make this an affordable hobby. In case anyone is interested, with enough orders(minimum 30) then I can offer these for only $15 each. please send any feedback. =Dan Roganti -- [ My Corner of Cyberspace http://ragooman.home.comcast.net/ ]

=== compaq SLT-286 power supply ===

by f5inl＠wanadoo.fr

Hi, I recently acquired an old Compaq SLT-286, but unfortunately, the power supply was not given to me. So I had to find a way of making it work by myself... I tried to connect a + 12 Vdc to the power connectors that normally are assigned to the battery. I put the ground on the most right pin, and a +12V on the most left one. The two middle pins were left unconnected, and of course, I removed the battery to avoid shortcuts. ( Ooops...when I say left/right, it's when the computer's screen is facing me, keyboard is removed, and the battery connector is located on the top/left corner :-) Like this : +------------------+ | **** | | ABCD | | | | | | | | | | | +------------------+ A : +12V D : GND BC : left unconnected With this, the computers boots normally on the floppy drive, but refuses to boot on the Hard drive. I obtain a 162 error message, inviting me to run SETUP. Then, I tried to run the compaq "setup.exe" diagnostic program, and I managed to see that my hard drive is perfectly recognized ! So, could anyone tell me il if I missed something ? Is my +12 Vdc connexion enough for powering the whole computer ? Actually I find very surprising that the battery's power connector has four pins, and I managed to do it work with only two :-( Thanks for your help, guys ! Sincerely, Fred.

SGI IRIX licenses?

by darin.lory＠gmail.com

Richard, As most of group have mentioned that you need a support contract or purchase the MIPSpro compilers (C, C++, F77, F90, Auto- parallelization, GNAT Pro ADA 95) specifically for your host which you intend to run on. The FlexLM license file is in /var/flexlm/ license.dat. You might want to check your IRIX workstation or server you are doing your IRIX install on, and see if you already have any licenses in this file. You might be surprised if your SGI might have previously been licensed. You can print out or copy this file for safe keeping. Upgrading within IRIX 6.5.x will not modify this file. You will need to contact your local sales office (http://www.sgi.com/ sales/ ) or call SGI at (800) 800-7441 or (650) 960-1980 if you need a license. You will probably need a quote for a 2CPU license (even if you are running on a 1 CPU workstation). Depending on the version of IRIX, it did place some freebie licenses in there. They also used to produce a "HotMix" CD with all the sample or open license software. I believe I still have a lot of these HotMix CDs from IRIX 5.3, 6.2, 6.3, 6.4. I would suggest that you setup a free Supportfolio account and see what you have access to. https://support.sgi.com/login SGI will give you a 30 or 90 EVALUATION license for any software, so you can try out the MIPSpro compilers and see if you want to go for the cost of the software http://www.sgi.com/support/licensing/ . The MIPSpro compilers really take advantage of the SGI architecture and IRIX, more so than GNU software. But depending on what you need, GNU compilers might be fine for what you are doing. Some of the Development tools (http://www.sgi.com/developers/ technology/irix/tools.html more info) you can download and may get a PERMANENT license for ANY host (HOSTID=ANY in license.dat). You can download most of the available software (except compilers) at http://www.sgi.com/products/evaluation/ It will note what type of license (like FREE or no license needed). Most of the stuff that might interest you are things like Cosmo Player, Open Office, Message Passing Toolkit 1.9 and Parallel Virtual Machine-PVM (I have PDF version of non-copyright books on PVM and MPI if you need them), Java (1.4.1_06 which is NOT DST compliant without a patch that they created from a bug report I placed, but should be available from Supportfolio). If you don't want to purchase the MIPSpro compilers, the GNU compilers are available. All Freeware software is at http:// freeware.sgi.com/ and all the manuals/books are at Techpubs in HTML and PDF format http://techpubs.sgi.com . C++ coding standard for IRIX and GNU C++ are at http://www.sgi.com/tech/mlc/docs/cc-coding.ps I suggest if you can get it, to install IRIX 6.5.22 or later. IRIX 6.5.30 is the latest. You can then install the DST (Daylight Savings Time) patch for IRIX 6.5.22 to 6.5.30 (new patch for 6.5.30). IRIX 6.5.2f to 6.5.21f (f for Feature set, m for maintenance) require you to download a new tzdata file (from tp://elsie.nci.nih.gov/pub/), modify /etc/TIMEZONE, and run the zic compiler for your locale. I can email you or provide you all this information if you need it. I also wrote TONS of documentation for work on installing IRIX, startup/shutdown procedures, backup procedures and I can send that to you also. I have expertise on IRIX 4.0, 5.3, 6.2,6.3,6.4 and 6.5.x on all kinds of MIPS and SGI hardware from MIPS workstations, SGI Personal IRIS, Indys, Indigos, O2s, Octanes, Crimsons, and Origin servers (200, 300, 3800). But I only have Indys, O2s, Octanes, Origin servers, and maybe an Indigo Impact for me to use. Most of everything else was upgraded or replaced. Let me know if you need anything. I'd be happy to help you out. -Darin

Repairing the damage.

by RodSmallwood＠mail.ediconsulting.co.uk

Hi The abortive attempt to cluster the two Vaxes and copy data has left me much further back than when I started. The network and terminal server connections are gone because I can't start TCPWARE up. It complains about a license and and something called NETCU (What the hell is that?) and aborts the loading of TCPWARE. Lesson learned,= the boot from a cluster server idea is flawed and can damage an existing setup. Its probably one of those things everybody has heard about but never actually done. Back up did somebody say Back up.? The whole reason I attempted doing it this way is because despite the fact that both systems have TK 70 tape drives when attempting to do a backup on the -200 it keeps telling me the tape is write protected which it isn't. I'll try to sort that one out to-morrow. Rod

HP3000 rescue in Missouri

by pt＠new.rr.com

Interested parties please respond to original poster: The 935 is definitely on topic as is some of the other stuff. Does anyone have an image of a HP2627A color console? I had not heard of this beast. From: Michael Gueterman <m_gueterman at editcorp.com> Newsgroups: comp.sys.hp.mpe Subject: Office Cleanout! Date: Fri, 01 Jun 2007 08:00:48 -0700 Message-ID: <1180710048.105002.173340 at q75g2000hsh.googlegroups.com> Hello All! It's certainly been a while since I've looked in on the list/ newsgroup. Hope things are going well for everyone. Anyway, it's been so long since I've done any real HP3000 work I've decided to do some office cleaning and get rid of some old equipment. Most of this stuff works (or at least did when I shut off the power to them years ago :) but it's probably not economical to pack and ship. If you want it, you'll need to pick it up or I find someone to come and haul it away soon. The big one! HP3000 935, 2 cabinets with 3-4 eagle drives (I think one is dead if memory serves). This thing must weigh in at 1500 lbs plus! It has a couple of HPIB and one SCSI DAT drive. It does not have the SCSI boot firmware (sorry). I got this used myself several years ago and used it in the developers program so I don't have the MPE license for it. I'll also throw in the HP2627A color (Star Trek) color console! This is a package deal so no cherry picking (that's probably the only way someone may make the effort to get it :) Oh, there's also a HP9000 E55 in the same cabinet (had to stick it somewhere). Let's see, there's also a couple of A2094 monitors, a HP9000 712/60, a 2345A DTS, some comm equipment when we had our T1 line, and who knows what else is buried in the back (probably mostly trash). I also have some of the beige soft-bound manuals sitting on a shelf. I'm going to hang onto the 928 even though it's been powered off for over two years for sentimental reasons. I regret giving up my TRS-80 Level I system back in 1995 so some old stuff I'll keep :) I don't really expect that anyone will drive to mid-Missouri to get any of this, but wanted to offer it up before it finds it's way to an electronics recycler. It's just not worth it to me to package/ship anything so before someone says "Hey, I'll take blah blah blah if you can ship it", the answer is no. So, how is the "open sourcing" or at least the "prying of the source code from HP's hands" going for MPE? Regards, Michael L Gueterman Integrated Information Systems, Inc. --

HP 1000 21MX Wont turn on, No PS voltage

by g-wright＠att.net

Hi, I have a HP 1000 21MX that wont bring up the Power supply. Has AC to it and the fans come on. It has a some what different battery backup connections on the rear than a 2117F. I tried the resister jumper from a 2117F but no go. There is no voltage output from the PS on any leg. Is there something different about these or do I need to trouble shoot the Power Supply Thanks, Jerry Jerry Wright JLC inc g-wright at att.net

There does seem to be less potential for >ambiguity in a RPN language that has one operation per instruction. >(which is what makes machine language so fulfilling) Actually not. My first language exposure, like most, was BASIC. About the same time, I was doing 8080 machine code and 8048 code. I then did a lot of work with PLM/80 and more 8080. I fiddle a little with SmallTalk. It was about this time that I was exposed to a HP 35 calculator. With the combination of machine coding and high level languages so far, I could clearly see that RPN was concise and didn't need special thinking. About the same time period, I got my first taste of Forth. I was already sold on RPN and just had to learn what to do with the stack. I've since played with apl enough to know it doesn't make sense to me. Still it does look interesting from the standpoint of minimum entry. I've also written a few macros in LISP for AutoCad stuff and once for emacs. I current deal mostly with verilog both gate level and behavior. Still, I find that I'm most productive in Forth. Execution typically reads left to right as most would have expected the example to have done. There is no ambiguity about what is done when. I like that! Others don't seem to like that :( In some sense, Forth seems like machine language to most but I find that my code reads like sentenses. Especially as I abstract farther from the Forth low level words. It isn't English but it is clearly sentenses stating just what I want done and when. I've not seen any other language that does that and still has well defined excution order. I find that I factor code better and have less errors writing in other languages after having been exposed to Forth. I still enjoy writing in Forth more but few pay for that.

Yes, I know of people running older MIPS-compiled Red Hat 5.1 Linux or Debian Linux (http://members.optusnet.com.au/clausen/sgi/LINUX- IP27-HOWTO ) on SGI Indys or O2s being the most popular. There is also a Linux on MIPS Wiki at http://www.linux-mips.org/wiki/ Main_Page Or even SGI's own webpage http://www.linux.sgi.com/mips/ with downloadable Hard Hat (Red Hat Manhattan) 5.1 Linux http:// www.linux.sgi.com/mips/software.html I've heard of people using Origin 200 and Octanes (R10K or R12K MIPS) with Linux but that was after any playing I did with Linux on an Indy. MIPS Technologies (after splitting off of SGI) developed many new MIPS processors like the 24K, 34K, and 74K that are used with their Malta board and Linux from a couple of partners (4K processor also used by these partners). http://www.mips.com/products/softwaretools/ system_software/Linux.php -Darin

Semi-OT: Need help identifying diode specs

by pat＠computer-refuge.org

I picked up a few spare diodes from my local surplus place, and I need some help identifying them.. They're about 3-3/4" long and 1-1/4" wide at the (hex) mounting base, have a threaded negative terminal, and an approx 1/2" diameter positive terminal on the top. They appear to have a Westinghouse (underlined W in a circle) logo on them, next to a diode symbol marking polarity. Next to that is the number "18840100" (part number?) and "8206" (date code?). Any idea what voltage and amperage this diode should be rated for? I tried googling for info, but only found a few places that wanted to sell me one (with at best the info that it's a "semiconductor diode".. gee, thanks). One site also listed the part number "5961-01-198-6175" as an equivalent. Thanks much, Pat -- Purdue University Research Computing --- http://www.rcac.purdue.edu/ The Computer Refuge --- http://computer-refuge.org

It depends on what you've got, but you might try finding a gcc cross compile toolchain, for say linux (or even cygwin) and then using the "objdump -D" program. You can get it to disassemble from an unformatted binary file... that is sometimes useful if all you have is roms. I think gdb has a 68k emulator, but if not there are many around to choose from. You should be able to quickly whip up something to sim the code once you've figured out the basic structure, i.e. where it boots form and where it expects ram, etc... just a thought. i'm big on simulation. There may be other tools for win32 I don't know about. I'm most comfortable with linux/unix & gcc. You can certainly build 68k code with gcc. I did it for years. -brad

Sun, HP "scrap" (???)

by dasbooterror＠gmail.com

As it goes, having actually run the gold scrapping grunt work (Read: Play with the Aqua regia) The reason you don't melt gold like that is the sheer amount of energy you have to waste to do it! Not to mention contaminating your final gold product with whatever crap is in the batch. As other people mentioned you can use mercury or cyanide agents, but good luck getting ether of those agents in any quantity, much less an EPA permit to use them for gold refining. Aqua Regia is bad enough, as you need to neutralize it before disposal. As it should be noted we refined chips, leads and anything gold plated Our usual contaminates were tin, lead, platinum, silver and iridium. ( Note: Using your left over Nitric Acid to make RDX does *NOT* count as disposal; However its a lot of fun)

Bringing the VAX 4000-300 back to life.

by RodSmallwood＠mail.ediconsulting.co.uk

Well I tried it. The two systems were connected together with 50Ohm co-ax and terminators at both ends. I hooked in a hub that had a BNC connector to monitor what was going on. After running @SYS$MANAGER:CLUSTER_CONFIG_LAN on the -200 it became a boot server and I did a BOOT EZA0: on the -300. Both systems were talking to the network but ignored each other. On the console of the -300 it just printed 'Retrying Network Boot' for ever. Hardly a surprise wth no DecNet or TCP/IP running. Oh well back to trying to create a bootable tape and put MOP on my list of fables and fairy stories.

HELP NEEDED - moving DEC PDP-8/A from Ottawa, Canada to VCF East (New Jersey)

by jack.rubin＠ameritech.net

Is anyone driving from or through Ottawa on the way to VCF East next weekend? I have an 8/A to pick up in Ottawa and will be at VCF. If you can provide help moving the (not small) system from Ottawa to New Jersey, I will be happy to pay $200 toward your gas expenses. An alternative might be someone traveling through Ottawa who could move it to Toronto or London (Canada!)in the near future, but the machine must be picked up in the next week or so. I'm on the digest version of classiccmp, so please feel free to contact me directly or call. TIA, Jack jack/dot/rubin/at/ameritech/dot/net 847.424.7320 work No virus found in this outgoing message.

Bringing the VAX 4000-300 back to life.

by RodSmallwood＠mail.ediconsulting.co.uk

Firstly a big thanks (THANKS) to all those who responded to the power plug question. I bought the VAX 4000-300 system on UK Ebay and did the 250 mile trip to Cambridge to collect it early on Saturday. These things are not that big but weigh a ton!! The guy selling it was lot larger than I (thank heavans!) I did not know the suspension in may car went that low! There it sat until Tuesday evening when my son (6'4" & 210pounds) who's a trained weight lifter helped me ge it out of the car and onto its wheels. It need a good clean inside and out but otherwise is undamaged and complete. I extended the notch in the power cable I had and fired it up. First level diagnostics OK Choose a language OK Boot er no but as it seems as the system spent some or all of its life in the insurance industry I'm not surprised the disks have been wiped. Ok so next move. I'm going to try and make a VMS 6.2 bootable tape on the -200 as the -300 has a TK70. The -300 also has a KZQSA (SCSI) controller and whilst they are no good with hard drives I think they work with CD ROM's I also have a stand alone SCSI CD drive (Yamaha CRW4416SX) it has the really small SCSI plugs (inch and a bit long) on the back and the KZQSA has the really big ones. Comments on which is best way to proceed welcomed. Rod Smallwood

SGI IRIX licenses?

by legalize＠xmission.com

I've not installed IRIX from scratch before. I recently purchased some install media from ebay and the item description said "does not include licenses". Is this boiler plate disclaimer, or am I still needing something else to install the OS? Another item on ebay says it *does* include licenses. Is there some sort of license key? Does SGI have a hobbyist/deprecated-ware license available? -- "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/>

SGI IRIX licenses?

by compoobah＠valleyimplants.com

> MIPSpro (SGI's compilers) are the only things on the install CDs that > use > keys IIRC. One should be just fine installing gcc and friends from > pkgsrc. MIPSpro is not included in the default software library from SGI. What is included is the "IRIX Development Libraries" and "IRIX Development Foundations" which provide the headers, static libraries, and a few development tools (but not compilers). For IRIX 5.3, the full IDO (with C compiler) is downloadable from ftp.sgi.com, for IRIX 6.2 the IDF/IDL parts are on ftp.sgi.com (IRIX 6.2 did not ship with the development tools and headers as standard). Many versions of MIPSpro function as "nagware" and will still compile while you're waiting for your license >from SGI, or developer program members get access to an account on a Origin running the latest MIPSpro compilers. No official hobbyist program, there just isn't any return in it for SGI (the MIPS-based IRISes were discontinued in December).
