That's because of *chronic* exposure. The risk from a single small dose is not very high (though obviously it depends on the dose); your body will excrete most of the mercury (but not very fast, and over the last couple of decades, what's regarded as a "safe" level has been reduced quite a lot). The problems come when repeated exposure causes ingestion or absorbtion faster than you can excrete it. That's why spilt mercury is dangerous. It gets into small spaces, and takes a very long time (years) to vapourise (the vapour pressure is very low but so is the toxic level). Various mercury compounds have been used medically (eg mercuric chloride and mercuric iodide were used as antiseptics and fungicides). -- Pete Peter Turnbull Network Manager University of York

Anyone know how to set Aux port speed on Datamedia DT/80

by dave04a＠dunfield.com

Hi Guys, Just acquired a Datamedia DT/80 (nostalgic value - spent many 100s of hours in front of one of these during earlier parts of my career). Don't have docs, however it's a pretty accurate VT-100 clone, and almost everything from the VT-100 manual is exactly right. However, it has an AUX port which the VT-100 doesn't ... I can set set TX and RX speed with SETUP-B '7' and '8', however ASPD shows at 50 and I can't find anything to budge it... Anyone know how to set the Aux port speed on a DT/80 ? Are there any settings for Aux port data bits, parity, flow-control etc.?

ACP Computer Store in Santa Ana up on the auction block!

by news＠computercollector.com

Given the sudden interest, here's a copy of the autobiographical article by Dave Freeman, published in the June 7 issue of the Computer Collector E-mail Newsletter. (Shameless self-promotion: the intentionally primitive web site is http://news.computercollector.com) -- Evan K. ------------------------------ The Beginning Advanced Computer Products, Inc. (ACP) was founded by me, Dave Freeman, in the summer of 1976. While working at Fairchild and National semiconductor, I experienced first-hand the development of the basic monolithic integrated circuit into a microprocessor chip. In 1975, General Instruments developed an integrated video pong chip that minimized the number of parts required to build a video game. This sparked a massive video game war that included unlikely participants such as Ingersoll, Interstate Electronics, and other companies that got involved in building Pong machines. Before GI started shipping the AY-3-8500 video game chip, I negotiated an order of 25,000 pieces to support the hobbyist market via mail order. I convinced GI that this was a viable market that required extra support, and they agreed to set aside enough chips to support our needs. I developed a video pong kit and started advertising in Popular Electronics and later in Byte. The kit was available for $39.95, and the response was overwhelming. After two months I had over $80,000 in the bank. I still had a job with a semiconductor distributor, but I built and shipped pong kits at night. Then the unimaginable happened: GI reneged on my video pong chip orders! I had thousands of dollars of hobbyists' money and no chips to complete the kits. The demand for the video pong chip was so high that GI took another step placing the chip on allocation and shipping to only five manufacturers worldwide. Many video game manufacturers invested big on getting this chip. Many went out of business or lost substantial cash due to their inability to get the chip. I contacted the manufacturers that were getting parts and came across a contact in the Philippines that was willing to sell me ships via the gray market for cash. The only problem was the parts would have the part number and date code shaved off and the price would be a whopping 20 bucks each! This was four or five times the going price in the market. I arranged to meet this gentleman at Los Angeles Airport and purchased 1,000 chips at a time for $20,000 cash, and the parts were delivered in cigar boxes. He would then fly back to the Philippines. Fortunately for me, the parts were genuine and I was able to deliver the kits to our customers. This was the start of ACP. This was also the last time I would have a good night's sleep. Early Life in a Garage I quickly resigned from my position as vice president of the semiconductor distributor and concentrated full-time on supporting the hobbyist market via mail order. I worked out of a garage that had one light socket that we octopused enough lines to power the equipment required to process and ship orders. My brother Tom joined me at this time and we were in business. We added more integrated circuits to our mail-order ad such as the [Intel] 8080 microprocessor, and our mail-order business continued to grow. Soon we increased the size of our Popular Electronics ad to a full page and added Byte magazine. This was a huge decision at the time as one page in Popular Electronics cost $3,000. We decided to go for it and it worked. Our mail-order business doubled each month for the next six months. ACP Computer Retail Is Born I had a vision that the new personal computers just introduced into the market were going to be purchased from retail stores. I also believed that everyone would have a personal computer in their home -- a vision not shared by many during this time. In November 1976, we opened a retail store with 3,000 sq. ft. of retail and warehousing space. Our original name was Advanced Microcomputer Products. We eventually changed it to Advanced Computer Products due to a cease-and-desist order from Advanced Micro Devices (AMD). ACP was one of the first 10 computer stores in the nation and still holds claim being the oldest operating independent computer retail location on the planet. We quickly added computers to our offering and became dealers for Imsai, Apple, Processor Technology, TDL/Xitan, Smoke Signal Broadcasting, and Vector Graphic. In the early days, I recall trying to convince friends and business clients that there would be a personal computer in every home in the USA. They were not convinced and I spent several years talking about how personal computers were going to change the world. In those days, my early competitors in retail were The Computer Store of Santa Monica, owned and operated by Dick Heiser, The Byte Shop of Orange, owned and operated by John French and Hal Lashley (also George Tate of Ashton-Tate fame got his roots here). There was also Byte Shop of Westminster, owned by Marty Rezmer and their top salesman was Vern Raburn, who later held top management positions with Microsoft, Lotus, Vulcan Venture Capital, and who now builds airplanes in New Mexico. My Life with Apple Early in 1977, I got a telephone call from Gene Carter, national sales manager for National Semiconductor, inviting me to come up to Silicon Valley for a visit. Gene proceeded to pick my brain about the personal computer revolution. His main interest was Apple Computer. I told him it was for real and he immediately joined Apple as one of its first managers along with Mike Markkula and Phil Roybal. Phil had joined National as the result of my arranging an interview for him. Mike Scott, Steve Jobs and Steve Wozniak were already at Apple. I then became one of Apple's first dealers. ACP grew its Apple sales to over $5 million per year and actually set up a series of technology centers for the Greater LA Schools to train teachers. Still an independent, we were one of the top Apple resellers in the country. Other Apple dealers in the Southern California area included: Wabash Computer, Priority One and Computique. Apple quickly let their early success go to heir heads and started changing the policies and procedures for resellers. Apple tried to control the entire market and unfortunately forced many resellers to exit the retail computer business. Apple management became more and more concerned about dealers selling their computers via mail order. My good friend, Gene Carter, whom I helped to decide to join Apple and become a mega-millionaire, sent all Apple dealers a new contract. This contract would add the condition that Apple had the right to change the contract with only 10 days notice. Within days a new contact was sent out giving all dealers 10 days to be out of the mail-order business. All Apple sales would require a "face-to-face" meeting with the end customer! ACP had just distributed its new mail order catalog with a 12-page Apple-only color insert. This represented a major capital commitment on the part of ACP. We basically bet our business on future Apple business we would get from the new catalog. Unfair, that is an understatement! ACP joined with five other dealers such as Olympic Sales to sue Apple for its mail-order ban based on the Robinson-Patman fair trade agreement. Unfortunately for us, Ronald Reagan was in power and big business was protected by his administration. We lost in a summary judgment. (About this time we received a call from the White House and they ordered 15 memory upgrade kits via mail order. We gave them open account and received payment in 180 days!). All of the other mail-order companies involved in the Apple lawsuit went bankrupt. ACP survived but lost millions of dollars as a result of the Apple decision. It's fair to say ACP was not the only one to become a victim of the arrogant, self-serving decisions to be made by Apple in the future. Ironically, Apple is now a big player in the mail-order business and at the time of the lawsuit Apple had a small software mail-order business as well. Trying to adhere to Apples policies of prohibiting sales of computers outside our approved ZIP codes and requiring face-to-face meetings, I recollect calling Apple one day to see if we could handle an order for 20 Apple II computers for an education center in Katmandu, Nepal. They approved this transaction and ACP was the first to introduce computers to Nepal. I never understood this decision and never will. In 1986 we ceased to offer Apple products in view of their desire to only sell to major chains such as Businessland, Sears, Computerland, and others. The personal computer had become big business. Operating a Computer Retail Store Operating a computer retail store in the early days from 1976-1980 was a real test for any businessman. Cash flow was generated by selling computers for cash (usually cash in advance.) The problem was in those days that all manufacturers demanded cash in advance for computer purchases. Credit lines were non-existent! Distributors were also not yet founded. Imsai, one of the first personal computer manufacturers, would make us send cash in advance plus order significantly more computers than we needed. Our salesman was Bill Lohse, who went on to be the publisher of PC Magazine and executive for Ziff Davis. The toughest decision we made on a weekly basis was how much cash to send computer manufacturers and will they go out of business before they complete our advance orders. Market Driven by Computer Shows In 1977, ACP participated in the first West Coast Computer Faire, founded by Jim Warren. This became the foremost showcase for new personal computer products and we were part of all of them. Apple introduced its Apple II at this show and wowed the computer hobbyists with a live demo of "Breakout". Mike Scott personally handled the demos! ACP also participated in the world's second computer show held in Trenton, New Jersey (the first was held in Atlantic City a short-time earlier). Computer shows became very popular through 1979 as we traveled to Boston (Wayne Green's Shows), Toronto, Philadelphia, New York, Houston and many other venues to show our products. The key show and the most significant show however, continued to be the West Coast Computer Faire in San Francisco. In 1977 the first Comdex show was held in a back room at the MGM Grand Hotel in Las Vegas. I was there and it consisted of about 50 booths, and who would of imagined that Sheldon Alderson would turn Comdex into the success that it has enjoyed over the years! Let's Build It In 1977 ACP developed one of the first 4K memory boards for the Altair, Imsai, and other S-100 bus computers. Our card solved the instability and quality problems other 4K cards had and our sales took off. We then added other S-100 cards. We then developed the Z-80 Softcard for the Apple and a 256K memory card. We negotiated an OEM agreement with Microsoft and built more than 250,000 of each card sold under the Microsoft name. Our manufacturing business became so big we spun it off under Vista Computer and added more upgrade cards for the Apple and the IBM PC when introduced in 1981. The World's First Computer Superstore In 1981, ACP opened two new stores, one in Tustin the other in San Jose, California. Our San Jose store was named ACP Technology Center, and it was the first "Computer Superstore" in the country. Our objective was to open Computer Superstores in 12 major cities within a two-hour plane ride from Santa Ana. We hired industry executive Tom Anthony to roll out, obtain financing, and secure authorizations for our expansion program. We invested over a million dollars in opening this store. ACP Technology Center was an instant success. We then tried to obtain authorizations from Apple and IBM to sell their computers. The general concept of computer retail at that time was to have a store on every corner a la Computerland. IBM was really focused on getting an IBM medallion placed at every corner of the country. A Computer Superstore did not fit their model and we were too early to market with our concept. Six-months later Businessland convinced IBM that the way to go was computer superstores and IBM bit on it hook, line, and sinker. The rest is history. In fact IBM became so selective and restrictive as far as their computer resellers that the price of an IBM computer store medallion soared to over $150,000 for one location. First Computer TV Show In 1982 we produced the first TV show for personal computers on channel 48 in San Jose. "The Computer Show" was hosted by our store manager, Manny Lucero, and featured special guests and new product introductions for the first 30 minutes and the remainder of the show took call-ins from the viewers. Guests included Steve Wozniak, a real supporter of the show and the store even though his brother had his own computer store in Cupertino, as well as Steve Jobs, Philippe Khan, Paul Terrell, and others. The show continued for two years and we were forced to go off the air as the costs increased dramatically and it was difficult to get marketing funds from manufacturers at that time to support a TV show. Collecting PCs I always knew there was something special about the genesis of the personal computer revolution. I started early collecting PCs and remain an avid collector today. The PC Museum has over 700 computers at the present time and our objective is to someday create a venue where this memorabilia can be displayed to the public. Our website is at www.thepcmuseum.net. Donations If you have anything to donate please let us know as there are still some computers that we do not have. The short list of computers we need includes: Sphere, Ithaca, Byt-8, PolyMorphic Systems, Heathkit H8, Cromemco, TDL/Xitan, Smoke Signal Broadcasting and Apple I. We also need all the memorabilia and photos that we can get related to the history of personal computers. If you have historical information about the systems we have online, we invite you to submit the information to share with our website users. It has been a special 28 years for me. Just surviving the unpredictable changes in the personal computer field, which has been a roller coaster ride, it is simply amazing that we are still here today. The memories we have of the industry and people we met and worked with has made it all worthwhile. Our customers have also given us many rewards from their continued support and the friendship we have enjoyed over the years. I am sleeping a little bit better these days!

version of MSDOS 6.22 expand.exe for Linux?

by julesrichardsonuk＠yahoo.co.uk

Does anyone know if there's a decompression util for Linux that can handle MSDOS 6.22 compressed files? I need a decompressed version of emm386.ex_ ... The only one I've found (so far) is called msexpand - but (helpfully) it supports every version of MSDOS ever apart from 6.22 :-( Unfortunately I'm surrounded by Linux machines right now and nothing with a hard disk onto which I can install DOS - and I don't think I can boot DOS 6.22 from floppies and tell expand to decompress a file into memory, let me change floppies to the one I want the expanded version on, and then write it out... :-) If it comes to it I can dig my old 486 laptop out of storage as I think that wound up with 6.22 on it - just a pain though! ta Jules

survived another one!

by rigdonj＠cfl.rr.com

Second hurricane in three weeks!! Just got power back after hurricane Frances. This one was HUGE!!!! It reached from the FIorida Keys to Atlanta Ga! It started raining here Friday. HEAVY rain and winds all day Saturday and Sunday. More rain Monday (and a curfew in effect). Today (1:30 PM Tuesday) some rain bands are still passing through. Three tornadoes in this area yesterday and another today. The worst of the storm was south of us this time and everything around here that could be blown down was already down due to Charlie so now as much damage this time but HUGE amounts of rain. I set my canoe outside last week and it was FILLED completely full of rain by Friday night. Luckily Florida is flat so rain doesn't concentrate much. NOW it looks like we're in the path of Hurricane Ivan!!! It's scheduled to be in this area about Sunday or Monday. UnF***ING believable! joe

I think it can even be part of some organic compounds. It readily reacts with even dilute nitric acid to form nitrates, or with aqua regia (a mixture of nitric and hydrochloric acids) to form mercuric chloride, also known as corrosive sublimate. It reacts slowly with sulphur, chlorine, or oxygen (cinnabar is mercury sulphide). Pure mercury sulphide used to be used as vermilion pigment (which may explain something about some artists). It reacts dangerously rapidly with bromine, and reacts with ammonia (don't try this at home!). The oxide reacts with quite a lot of things; it's used to make mercuric sulphate which is (was?) used as for some organic reactions. BTW, the reactions with oxygen and sulphur are very slow, which is why mercury vapour is, well, mercury vapour (rather than mercury oxide); and why the advice that used to be given to use flowers of sulphur (finely powdered sulphur) to mop up mercury spills is not very good (use zinc powder instead, to make a non-volatile amalgam). Some of the compounds are very toxic, and some can react with organic materials to produce organo-mercuric compounds (some list members are old enough to remember the Japanese fishermen who were poisoned by consuming them in fish over a long period). Lots of these are liquids with high toxic vapours. -- Pete Peter Turnbull Network Manager University of York

Having problems with SCSI MO drives

by vcf＠siconic.com

I'm trying to connect up various MO (magneto-optical) drives to a PC via SCSI interface and having consistent problems. The adapter in question is an Adaptec AHA-1542CP. The errors are: Host adapter status: 00h - No host adapter error Target status: 02h - Check condition Sense key: 02h - Not ready Sense code: 0Ah I'm not a total SCSI expert so I'm not figuring this out. Is there a termination issue? As far as I can tell both sides of the chain are terminated. The drive is hooked up externally and I'm using an active terminator. The host adapter should be terminating internally. What generally causes the above errors? I'm getting it on multiple drives across multiple adapters.

I would certainly be willing to do it, if nothing else for the sake of the experiment, since while logic is telling me that the IIISi and 4Si are the same printer except for those boards, I've never actually tried a swap. The problem is that I would only be able to do it after I get Peter's 4SiMX in my hands (that's assuming Peter wants to give it away for free and no one else takes it first), and I don't know when I'll be in the Bay Area. While having a source of spares for mine would certainly be nice, I won't make a trip to the Bay Area just for that. I normally go there twice a year for the Bay Area UFO Expo and for Conspiracy Con, but the Bay Area UFO Expo just passed two weeks ago and Conspiracy Con is in May. I don't think Peter would hold the printer for me for that long. > The former is marked as J005, the latter J014. These are some kind of test/debug connectors and aren't used in the field. MS

What was I running and can it be emulated?

I think it had Algol and Fortran and Assembly Language as it's languages. -- It was probably either DOS-M or an early RTE A lot of work has been done recently getting these OSes running in SIMH, so it should be possible. I don't know if Bob has put bootable disc images up for them yet, though. I have all of the manuals scanned, but not on line yet for these two systems.

DEC Storageworks BA356 questions

by tpeters＠mixcom.com

Hello all, new guy here, first post, help? I saw some info about some DEC SCSI enclosures, probably RAID boxes, holding 7 drives each, with power supply and "personality module." There wasn't enough info in the post I saw to get me going. I wonder if anyone might consider attempting answering a question or two for me, as I have a pair of these myself. They are marked MODEL SHDA2-ZZ on the back, and have 7 empty drive containers each. The fan modules say BA35X-MD 2x which makes me suspect that I have a pair of DEC Storageworks BA356 enclosures. They are gray in color. They each have a personality module, apparently both BA35X-MH. What do the switches do? The personality module with the sticker on it that says SHELF 2 does NOT have the switches set according to the decal on the module-- they are all off, whereas on the decal, one is advised to turn switches 1-3 on and leave 4-7 off. The module from the other unit is marked SHELF 1 and is in fact set the way the decal advises. Are these personality modules in fact RAID controllers? Are they meant to provide logical unit control, so that the enclosure looks like one SCSI ID to the outside world, with logical units on it? Or do the SCSI ID numbers assigned by the enclosure get passed through to the SCSI connector? Is there any software out there to configure these units as to what flavor of RAID to use? E.g. for Windows XP or Red Hat Linux? Many thanks in advance if you can help or point me in the right direction. -Tom

The problem is that the observed symptoms still don't translate into a fix. Prior to replacing the job offset assembly on my NX, it had the following problem when printing to the main output bin: the paper would feed through perfectly fine, but just as it was beginning to emerge >from the last rollers, it would stop and the front panel would indicate a jam. The paper was not jammed, and if pulled out manually the printout was perfect. Obviously it was simply moving a bit too slow, and the DC controller had very little margin in the number of clock cycles allotted for the sheet to clear each sensor, causing it to barf. This much was clear. The problem is, how does one go about fixing it? There was no component I could directly lay the blame on. Replacing the job offset assy fixed it, and while the practical side of me is happy (the new assy was pretty and shining clean, the old one was dirty and ugly to the sight and to the touch), the purist side of me, the part of me that reads your posts and aspires to be more like you, is still quite unhappy about the whole episode, since I never understood WHY replacing the job offset assy fixed the problem, and what exactly was wrong with the old one. > FWIW, the DEC LN03 (I have one, I think mine is the Postscript model) is not > a Canon engine... I suspected that it was one of the rare exceptions, thanks for the confirmation. BTW, am I correct in that LN03R is a pure PostScript printer, i.e., PS ONLY and cannot work like a plain LN03? This would make the LN03R quite different from the later LNs, and that is why I've long felt that only the original LN03 is the real thing and that the later LNs pale in comparison. And the later LNs are based on a Canon engine, and I seem to recall a low-end cheapo one at that... Don't remember what ?X, but I seem to recall it's the same one as in "Personal" LaserJets and LaserWriters. > Are the scanners the same?

I thought the same, and the part swapper guide gives different part #s for the IIISi and 4Si Laser/Scanner assemblies. However, a guy here in San Diego who professionally repairs these printers told me that he had swapped all kinds of parts between IIISi and 4Si that you are not officially supposed to swap and it worked; only the formatter and the DC controller are different he claimed. Maybe the scanner assembly has some kind of switch or jumper inside? MS

Isn't the print engine fundamentally limited to its fixed set of paper sizes? This set includes several envelope sizes (3 I believe), but don't you have to choose one of them? And what PS code are you talking about? Can you share it? Is it Level 1 or Level 2? Did you really define a page size that is not in the firmware? How did you do it?

der Mouse <mouse(a)rodents.montreal.qc.ca> wrote: > Does the collective list wisdom include repair hints for an HP LaserJet > IIISi? I have one. I have a 4Si, and as I've learned through 20/20 hindsight, it's exactly the same printer as the IIISi with the exception of two electronics boards (the formatter and the DC controller) which have been redesigned to do 600 DPI. The outside box and every internal part except for those two boards are exactly identical. I wish I had known this at the time I got mine. In July I went on a truck trip with Fred van Kempen to Mountain View, Calif., and as we were walking through town to his house after having left the truck at his office, we stumbled across a LaserJet IIISi left out to pasture by the side of the road. I wanted to pick it up and take it with me on the truck back to Southern Calif., but Fred strongly dissuaded me ("Mike, don't bother with this piece of junk, it's a 3 and you want a 4"). Had I picked it up and taken it, I would have probably saved a bunch of money on replacement parts I had to get for my 4Si after I got it to make it work fully. I got my 4Si from eBay for $60 (plus $99 for shipping), and as one can expect for this price, it came completely stripped of everything optional, i.e., of everything that isn't required for it to come up and print a test page. It came with only the base 2 MB of memory (perfectly reasonable for a little personal laser printer, but an insult for what's supposed to be a high-end print server), and of course my sheepish hopes of getting a PostScript module and/or a duplexer with it were dream, dream. There was one surprise of the pleasant kind, though. It was listed on eBay as having an Ethernet MIO card, but it came with a serial MIO card instead. Not even serial/parallel, just serial. Whoo-hoo! Purrfect! Of course everyone else in the world wants Ethernet and considers serial slow old stuff, I am me. :) One thing I did take from the IIISi in Mountain View was the serial/parallel MIO card, but I ended up not needing it. Just serial is better for me. Besides, unlike the IIISi one, the 4Si formatter board has a built-in bidirectional parallel port (something I very much disgust because it's so non-Classic) and having two parallel ports on the back only one of which is working would just look ugly. The bad news was that it would only print to the rear output slot, and any attempts to print to the main upper output bin resulted in front panel error messages about jams. I've called PrinterWorks (great laser printer gurus, www.printerworks.com) and they advised me to replace the job offset assembly. But I was still stuck at the point of not knowing how to take the sucker apart. OK, it was obvious how to get to the formatter board to add the PostScript ROM and memory SIMMs, but the engine resisted my attempts to figure out how it comes apart. So I went looking for a service manual. Found found on eBay in PDF on CD, bought it, had to wait for the CD to arrive, then go to Kinko's and have the PDFs printed. It was a pretty good deal: in addition to the combined IIISi/4Si service manual from HP (which is what made me realise that they are the exact same printer), there was also a generic laser printer repair book that taught a lot of general principles not specific to any given make or model, and approched things from a rather Tony Duell-like perspective. With the help of the service manual (OK, part swapper guide) I figured out how to take the sucker apart. I got to the job offset assembly and took it out for examination. It was dirty with grease, but not in the paper path, and there wasn't anything obviously wrong with it. I was hesitant at first about just buying a new job offset assy and trying to swap it in and see what happens, having heard Prof. Duell's admonitions against randomly swapping parts. But then I broke down and did it, as there was just nothing wrong I could see, it just didn't work. Familiar feeling, eh? Absolutely nothing wrong, it just doesn't work... Well, after buying a new job offset assy and putting it in, the problem went away and the printer now happily prints to the main output bin. I will never know what was wrong with the old job offset assy as the shop I bought the new one from required a core return. (By the way, even though job offset is a feature I absolutely don't need and have turned off, the job offset assy is a required part of the print engine and must be present and in good order whether you need job offset or not.) Then I needed to fatten it up with options. I needed the PostScript module of course (I consider PostScript to be the one and only printer language, so a laser printer without PostScript is a boat anchor to me), and I got it even before I fixed the main output bin woes. On the 4Si the PostScript module is a ROM SIMM that takes up one of the 4 SIMM slots. It's PostScript Level 2. After I got the main output bin working, I bought the duplexer from PrinterWorks. One of the reasons I needed a high-end printer is to print big specs and other stuff to go into 3-ring binders, so duplex printing is very important. It works, so I'm happy. Of course I needed to get more memory too. It was not happy at all with the duplexer and PS in there and only 2 MB to live in. Fortunately, I found a set of 3 compatible 8 MB SIMMs (maximum with one slot tied up by the PS ROM SIMM) on eBay for dirt cheap and now I have 26 MB total, the maximum with PS. It now works like a charm, configured for PostScript only (I like the pretend that PCL is not there), with an H8571-E MMJ adapter fitted into its stupid female DTE connector and connected to its driving 4.3BSD-Quasijarus host with a DECconnect MMJ serial cable, or The One True Interconnect. I wrote the 4.3BSD-Quasijarus support for it, which will appear in the next release. Since it'll be released, I wrote the code for pure PostScript: it assumes a pure PS printer like the original Apple LaserWriter or DEC LN03R (something I would very much love to have for fun and experimentation, but unfortunately lack) and never allows the HP printer to fall out of PostScript mode into PCL. Plain text given to lpr is converted into PS by txtps, a 4.3BSD-Quasijarus utility, and *not* sent to the printer as-is. I also added functionality to lpd to control options like duplex (so I can do lpr -Php4si -Oduplex mydoc.ps), and it's implemented using PostScript Level 2 standard setpagedevice operator, NOT HP proprietary stuff like PJL commands. (Of course it's open source and modular, though, so if you need to modify it to work with your PostScript Level 1 printer, you can make it do whatever is necessary, provided that you can figure it out: I have no idea myself how to, for example, programmatically turn on duplex on a IIISi with PostScript Level 1.) > Yesterday, I turned it on, same as a zillion times > before, and it didn't come up normally; it was making an odd ticking > noise. I went to see what was up and smelled that unpleasant smell > that usually means the magic smoke has been let out of something. Reading the follow-up posts in this thread, I see that you've already found the failed PSU capacitor, so (hopefully) you should be all set once you find time to replace it. Feel free to ask again if you need more help or a copy of the service manual. After all this tinkering with mine (cleaning it inside out, getting to and replacing that job offset assembly, and fattening it up with options), I feel like an expert on the NX engine. Yes, like just about every laser printer in the world, it's a Canon engine, and this one is NX. The word engine is a bit misleading: I originally thought it meant something internal and did not include the outside appearance of the printer and input/output options like paper trays. As it turns out, NX engine means not just some inside guts like the laser or the motor, but the entire printer from plastic covers outside to the last screw inside is made by Canon. The ONLY HP part in there is the formatter with its associated I/O ports and font cartridge slots on the right side of the printer. This means that other printers based on the same engine will not only have some similar parts inside, but will look exactly identical outside except for a different logo painted on the top plastic cover, and the insides will be identical to the last screw rather than just share some common parts. Whew! I really did not expect that, I thought there was more diversity in the printer world. As some people may remember, prior to deciding on buying this HP 4Si, I was asking on this list a bunch of questions about DEC PrintServer 17 (LPS17), which was another printer I was considering. Well, imagine my amazement when I learned that it is also based on the NX engine and that the two printers I was debating between (LPS17 and HP 4Si) are in fact exactly the same printer with a different formatter board fitted in the pan on the right! Small world... The NX engine has 300 DPI and 600 DPI versions, and the difference is only in the DC controller board. Every other part is the same, as are options like the duplexer. Formatter boards would be different too, not just between HP IIISi and 4Si (which have a bit more significant differences at the formatter/personality level), but other folks like DEC who used the NX engine would have had to redesign the formatter board for the higher resolution when going from NX/300 to NX/600. But still, it's an interesting thought that all paper handling options, i.e., the duplexer, high capacity sheet and envelope feeders, etc., and even the plain paper trays are exactly the same between HP IIISi, HP 4Si, DEC LPS17, probably others... Speaking of paper trays for NX printers, I wonder if anyone here might have one piffling little plastic part they would be willing to part with. Do you know the metal plate/bar that goes across the tray near its back (most protruding) end? That metal plate/bar has two plastic pivots on its side that hold it in the tray. The right pivot in one of my trays is broken, but the tray is perfectly fine otherwise. Since it's just this piffling little plastic part that needs replacement, I really don't want a whole new tray. It's not a matter of cost, I just don't want another tray, I want to fix the one I have. The piffling little plastic part I need has a part number, RB1-1074, it's molded into the plastic and it's a Canon part number, so it's the same whether it came from Canon to you through HP or through DEC or however. But no printer parts store is willing to sell me that piffling little plastic part, they want to sell me another tray that I don't want. So I wonder, would someone here happen to have a spare RB1-1074 that I could have? Perhaps from a broken tray that's broken in another way? TIA, MS

But it doesn't work; I get the usual walking > lights, then the 05 SELF TEST display, then SWITCHING TO PS; after a > bit, it changes to 55 SERVICE. The control panels lights and LCD are controlled by the formatter board. That's the big one on the right, the one that memory and PostScript options go onto and MIO cards and font cartridges go into, and the only board in the entire printer that makes it an HP LaserJet IIISi as opposed to, say, DEC LPS17. The fact that it walks the lights, enters the self-test and knows about PS indicates that the formatted board is probably OK. The formatter board talks to the DC controller, which is the main print engine controller, which controls the entire Canon-built NX engine. The formatter board throws up a 55 error if it can't talk to the DC controller. If the board you are having woes with, the one damaged by the blown cap, is indeed the DC controller board, then it's probably the culprit. The DC controller board is in the front right area of the printer, below the control panel, directly behind the plastic front cover. If you take a close look at the front cover between the tray openings and the font cartridge slots, you'll see a small hole. This hole provides access to the engine test button on the DC controller board. If you push this button, the DC controller will print an engine test page independently of the formatter, i.e., it'll forcibly override whatever the formatter is directing it to do and will work even if the formatter is missing or dead. Try it. But it looks like your problem is the opposite, good formatter and bad DC controller. > This may be because I still have all > the covers off - there may be sensor switches There are no sensor switches for the plastic covers. There are sensors for fans and it'll halt if any fan is unplugged. The AC input assembly in the PSU area has an interlock switch that cuts off the AC to the fuser and the "B" side of +24V DC that powers the main motor, the laser, and the high voltage supply for the imaging system if the top is lifted. The "A" side of +24V DC that powers all logic is always on. The only other interlock switches are the higher-level "top open" switch that doesn't cut off any power, but tells the thing to stop and complain about the open top on the LCD, and the EP cartridge presence detect switches. > I think one of you said something about having a service manual; does > it happen to say what 55 SERVICE means? -- quoting: -- The "55 Service" error indicates that the printer failed to initialize correctly at power ON. This means that the Formatter cannot communicate with the engine in order to establish the initial condition of the engine. This problem can be caused by a bad Formatter, bad cable, or by problems with the line voltage. Check and reseat connectors J4 and J5 on the DC Power Supply, and J8, J9, and J10 on the DC Controller PCA. Cycle the power several times to clear the error or to get another error that may better indicate the cause of the problem. If this clears the error, run an engine test print. If the error persists, replace the Paper Pickup PCA, the DC Controller PCA, the DC Power Supply PCA, the Formatter PCA. Finally, replace the Paper Input Unit. If these fail to correct the problem, check all associated cables for damage and replace if required. Any 57.1 Main Motor problem can also cause this error. -- end quote -- > Failing that, does anyone happen to have a spare board?

I think you are talking about the DC controller board. Someone just posted about having a bad HP 4SiMX for free for the taking. He said it jams, so that's probably a mechanical problem and the electronics is probably OK. He is in California (Bay Area), i.e., nowhere near you, but if you can convince him to take out and send you the formatter and the DC controller boards, that might work for you. You'll need both boards and the cable between them since it's a 4Si. Since the two printers are otherwise identical, swapping those two boards will turn your IIISi into a 4Si, i.e., you'll get 600 DPI and PostScript Level 2. You might also need a few other bits like the control panel (I'm not sure if they changed it), but nothing major and certainly nothing heavy. And if you two do work out that arrangement, I could take the rest for spare parts next time I'm in the Bay Area. (I'm in Southern Calif.) MS

I wonder if this was one of those caps that were made with the stolen formula for the electrolyte. I would guess that replacing the cap should put it back in working order. Do clean the board of the material that comes out of the cap. It isn't highly corrosive but it will cause damage over time. Even though you don't see a great need for a duplexer, they are quite cheap on ebay. HP wanted soemthing like $450 for these. I payed $15 plus shipping. The envelope feeder was about the same. The local Staples store ( a local office supply company ) was getting rid of old obsolete toners. I bought two HP toner assemblies for $25 each. This is the cheapest I've ever seem them. I've seen other manufactures for around $60 each. Dwight

OT(ish) - floppy quality

by julesrichardsonuk＠yahoo.co.uk

Is anyone else finding that new floppy disks these days tend to be total crud? I've just chucked yet another one (Sony) in the bin after it survived reading the data I'd put on it back a total of two times before it began to give read errors... (It's not the drive; I get the same problem regularly using several different drives, and have no trouble reading and writing to media that's several years old) Grrr! Jules

Does the collective list wisdom include repair hints for an HP LaserJet IIISi? I have one. Yesterday, I turned it on, same as a zillion times before, and it didn't come up normally; it was making an odd ticking noise. I went to see what was up and smelled that unpleasant smell that usually means the magic smoke has been let out of something. I turned it off immediately and have been spending the last hour or so trying to figure out how to disassemble it to find out what's fried (and try to estimate how user-replaceable it may be). But it's being difficult, and my replacement capabilities tend to operate at a coarser FRU grain than, say, Tony's :-); service doc would help (even if only the kind Tony not entirely unjustly calls just a boardswapping guide - it'd still help with things like mechanical disassembly). Someone with experience with the things would help even more, of course, but I can't really expect to be that lucky. I'm still working on pulling it apart to find out what let out that unpleasant smell.... /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

What was I running and can it be emulated?

by ron.hudson＠sbcglobal.net

Once upon a time when I was in High School, I used to visit Santa Clara University. I would get there 0-dark:30. I was able to use card punches to create my program decks, There were some sort of pre-punched JCL cards. Cards in Hopper - I think I pushed something - cards read 2100 rumbles Line printer starts printing. So It was some sort of batch system. I think it had Algol and Fortran and Assembly Language as it's languages.

DECMate II

by rich_bramante＠yahoo.com

I just rescued one of these. No docs/sw. It has 2 RX50 drives, but no hard disk. It powers up to a DECMate II screen with a flashing cursor in the ULH corner. Anything interesting I can do with this to play around without a hard drive? Any floppy images I can snag (will it boot from floppy?) Thanks. __________________________________ Do you Yahoo!?

The big cavity clearly visible from the rear with the covers off is for the duplexer. The socket in the corner of this cavity right next to the formatter/PSU area is where the duplexer connects, that socket is wired to the DC controller and is very handy for checking voltages. The other socket is on the front directly above the upper tray cavity, that's for the envelope feeder. It is wired to the Paper Input PCA. The service manual contains a one page main wiring diagram. No schematics for individual boards, but at least all inter-board connections are shown with pinouts. MS

Hi I think most of the error messages are listed but sometime it just says something like "replace the xxx board under the main board". If you know what I mean. Look at the board carfully. It sounds like you had a small electrical fire. Remove any charred PC board and look to see if traces are burnt through. Missing solder mask is not an issue but missing copper is. I'll look for my manual to see what it says( not here so will report back tomorrow ). This sounds like a PS board. Not having the drawings here, this might be the case. If so, the diode or diode bridge may shorted. This would wipe out the cap and maybe a few more parts. Dwight > >Failing that, does anyone happen to have a spare board?

For other, the IIIsi and 4si are heavy duty printers. Most of the cheaper table top models would not hold up to the kind of use these units will take. They are also quite fast as well. The one I have was used at the company I was previously at as a server printer ( hundreds if not thousands of pages a day ). I don't use it quite that much but it is great to have something that can do heavy work. If I have the information in digital form, it is better than having a copier. Dwight

It's to be shared on bitsavers, but I do not >want any money exchanged for anything that I donate. I have Barry's DVD - I find it very useful, and it's the cheapest way for me to get the material (in fact, it's the ONLY way for me to get some of the material). I also see a fair bit of material that I have scanned on it, and I have no trouble with that - in fact I have told Barry to go ahead and use any of my material that he wants. I recently (yesterday) finished all 7 SuperPET manuals (1500+ pages) and I have already contacted Barry to see if he wanted me to send them early (I have a lot of material backed up and probably won't get to a site update for another month) - I expect to see them on the DVD once he gets them, and I also do not expect the price will increase because they were added (think about why that might be). I live in the country where A) there is no high-speed service B) they are not putting in high-speed service, and C) they aren't planning to put in high-speed service in the forseeable future (I ask every couple of months). On a good day, I can get 2k/second download speeds, and I can sometimes keep that up for 20 mins before the connection goes down. [Thats why it takes time to update my site - I have to burn it to CD's and physically take it into the city] Having access to a DVD with gigs of material, a lot of which I will use is well worth what Barry is asking ... For that price, he is buying a good quality DVR-R blank, and spending his own time to burn it and ship it. Not to mention that he has obviously spent some time downloading and organizing the material. If he were charging $100 or $200, I might take offense, however he's charging $35, and frequently publishes the places where those who have the ability can get the material for free (except apparently some people don't want him to let people know where their "free" stuff is - Not sure how that makes sense). $35 buys about 20 mins of my time - I would spend a lot more than that trying to get the material via a modem, which would likely be unsuccessful. I've already extracted several very large files from the DVD that I've been trying to get for some time but have found to be "impossible" due to the size. I doubt he's making any substantial profit at it - in fact, given the amount of material that he himself has scanned and archived, I expect it's cost him lots in time and money over the years (it sure has me!). If he is able to make $5 or $10 a DVD, then I think thats good - it *MIGHT* be enough to keep him doing it, and might even help recover some of his other costs - but as noted above, I doubt he's making any real money from it. Are you willing to take the time to burn and mail DVD's of your "free" material when someone asks? How about if 10 people a week ask? Your position would prevent me from obtaining the material because I cannot download it directly from your site. I am also wondering how you manage restricting your site to only freenet subscribers? - clearly anyone using an ISP is paying for the delivery of your material, and that constitutes "money changing hands". In fact, they are providing delivery of your material strictly as a "for profit" business - they have absolutely no interest in preserving vintage documentation at all. A DVD - reasonably priced for the service it represents is no different - it's just a means of delivery (except in this case it is being done from someone who is active in collecting and preserving the material). Clearly he is not charging for the actual material (otherwise why would he keep telling people where to get it directly - well - at least the sources he's permitted to give out). And yes, I have also purchased Walnut Creek and InfoMagic CD collections which work out to a considerably higher $$ per meg than Barrys offering (and they are mass produced at far less cost than Barry's offering) - because for some people (like me), physical media is the best way to get the material. No: I don't know Barry other than that I have communicated with him a few times regarding documents that I needed or had available. Whew!!! --- nuff said.

[GreenKeys] Model 35KSR anyone?? (fwd)

by jpl15＠panix.com

An FYI for the List - I'm not affiliated in any way - and I already have one of these beasties; a nice, solid machine... ---------- Forwarded message ---------- Date: Thu, 09 Sep 2004 12:16:17 +0000 From: wa2hwj(a)att.net To: greenkeys(a)mailman.qth.net Subject: [GreenKeys] Model 35KSR anyone?? Greenkeyers, I have a very nice full-size Teletype Model 35KSR available. The typing unit appears to have never been used. Everything works, and the machine has the standard 20 ma. interface. The thing weighs about 150 lbs and shipping won't be cheap...but you know that! I will part with this treasure for $35 and can recommend a shipper. I can send pictures to anyone interested, but you'll have to wait until the weekend (when I'm at a home). Reason for selling: I need the space...for some reason my wife would like to park her car in the garage this winter(!). So, as I move stuff out of the garage and into the radio room, things are getting tight. When a difficult TTY decision has to be made, ASCII goes first! It is being replaced with two TT-4's and a TT-76 (Kleinschmidt's) and a complete AN/GRC-106 HF radio setup. (if you do the math, you'll notice that the newly-added stuff will take up more room than the 35...I said it was getting tight!) If interested, let me know...offer good only to Greenkeyers. If you come to pick up it (near Albany, NY) you might get some other goodies thrown into the deal. Otherwise, off to Ebay. 73, Jack WA2HWJ NNNN _______________________________________________ GreenKeys mailing list GreenKeys(a)mailman.qth.net http://mailman.qth.net/mailman/listinfo/greenkeys

For over a year now, my (and a few thousand others) website is on-topic for the CC lists. I don't have a copy of my 1993 website, but it's close to the copy I have from April 1994: http://wps.com/archives/wps.com.11Apr1994/ (The content is, let's say, a bit rough, in more than one way at a time, but So It Goes. I do find my obsession with file size amusing though, but this was a 16K bits/sec "nailup" SLIP connection to the Little Garden. Alas, the gopher server [remember when gopher was the killer net app after email?] was taken down by 1995. The 'about wps' link describes the hardware & software, in use Jan 1994, which seems today much todo about nothing.) http://wps.com/archives/wps.com.21Oct1996/ others in the index

Printer help?

by dwight.elvey＠amd.com

Hi der Mouse I have a IIIsi that I fiddle with every now and then. I also have an official service manual ( not much help for anything ). I suspect that they think that anyone working on one of these would be factory trained. Other than the occational cleaning and a problem with the last toner/drum assembly, mine works well. The only major failure I've had is the input card failed. ( a bummer since it was one of the harder to get parallel/serial cards and not the easy to get ethernet cards ). I've gotten some aftermarket RAM and put rediculously large amounts of RAM in it. It also has Postscript, a duplexer ( I got from ebay ) and an envelope feeder ( also from ebay ). Smoke is a bad sign. Good luck. Dwight PS While in the service, I had the nickname of "Mouse". It was because anytime anyone with gold braid on their cap would enter an area that I was in, I'd find a piece of equipment to hide behind. It was noted that I was like a mouse.

I'm very pleased with my VAX 4000/300 thus far, but I'm about to get a KZQSA card from someone, and I need to move my TQK70 controller over on the Q-bus so that the KZQSA card can fit into the machine. However, when I did a test run of this, the card was responding (show dev showed the card), but it wouldn't find the TK70 tape drive attached to the TQK70. Is there a jumper I have to set? Or did I screw up in some other way? Thanks. Phil.

Heathkit ETA-3400 Modifications

by Watzman＠neo.rr.com

I was sent a set of GOOD scans of the ET-3400 mods and have created a PDF file. It's now on the classic computer documentation DVD that I'm selling, but also I've asked Howard Harte to post it to his site, so hopefully everyone will be able to download it from there soon (perhaps by tomorrow (Thursday, 9/9)). I'm willing to scan any LOOSE (unbound) manuals and produce high-quality PDF files, I have a high-end 2400 dpi scanner with an ADF (sheet feeder) that can do over 200 page per hour (of double sided-material) unattended. Contact me if you think that you might have something not in the collection. Originals (or copies) can be returned. Bound documents are much, much more difficult, although I've done more than a few.

It looks like a Standard Bus but I think there should only be 50 pins. The TSC 800 is a dual slop A/D ( slow but very good resolution ). The AD667's are analog somethings by Analog Devices. They might be D/A's or analog swithces. It looks like there is a bunch of input amplifiers. This could be for anything from a simple A/D to a temperature measurement board. Anyway, it is definitely and analog interface board. Dwight

Reference From http://www.hgtech.com/Information/Mad%20Hatter.htm /begin reference Hatters really did go mad. The chemicals used in hat-making included mercurous nitrate, used in curing felt. Prolonged exposure to the mercury vapors caused mercury poisoning. Victims developed severe and uncontrollable muscular tremors and twitching limbs, called "hatter's shakes"; other symptoms included distorted vision and confused speech. Advanced cases developed hallucinations and other psychotic symptoms. The popular top hat of the time were made from beaver fur, but cheaper ones used furs such as rabbit instead. A complicated set of processes was needed to turn the fur into a finished hat. With the cheaper sorts of fur, one step was to brush a solution of mercurous nitrate on to the fur to roughen the fibres and make them mat more easily, a process called carroting because it made the fur turn orange. Beaver fur had natural serrated edges that made this unnecessary, one reason why it was preferred, but the cost and scarcity of beaver meant that other furs had to be used. Whatever the source of the fur, the fibres were then shaved off the skin and turned into felt; this was later immersed in a boiling acid solution to thicken and harden it. The acid treatment decomposed the mercurous nitrate to elemental mercury. Finishing processes included steaming the hat to shape and ironing it. In all these steps, hatters working in poorly ventilated workshops would breathe in mercury vapor. /end reference Haven't we all heard about putting on your thinking hat to solve a problem. Aren't computers just big problem solvers, so by induction a thinking hat is just a computer. Personally I hope my wife thinks I'm just "eccentric", not mad. I tell her it's better that I collect computers instead of wild women, drugs, gambling, cars, guns, horses, and speeding tickets. Mike

Econet for an RML380Z?

by julesrichardsonuk＠yahoo.co.uk

Has anyone ever seen (or heard of) an RML380Z with Econet network support (rather than the usual coaxial that RML used for its CHAIN network)? I picked up an SJ Research MDFS Econet fileserver the other day which I'll have running at the museum. However, the docs at one point (and one point only, it seems so far) mention RML380Z fileservers and 380Z machines with Econet. (I've got an RML380Z fileserver, but naturally it has a CHAIN network board and not Econet!) As I collect Torch, Acorn and RML stuff (and Torchnet is at least electrically compatible with Acorn's Econet) it's of particular interest as it implies one day I might be able to connect machines from all three manufacturers. I've never seen mention of Econet support in any of RML's documentation though, so have a feeling it was maybe a product that never saw the light of day... cheers Jules

Mercury in elemental form is not all that dangerous ( or most of us old timers would be dead or vegetables by now ). It is most dangerous as salts or as long term exposure to vapor. We had a diffusion pump fracture in a lab once with mercury in it. It did require that we had to remove the linoleum flooring but we didn't all strip and hose ourselves down. That is just plain silly. This is typical over/under reaction of today's world on hazardous materials. We fail to put things into perspective. We also fail to consider all of the consequences of the choices we make as well. Look at how we handle asbestos. Look at how California handled MTBE. Look at how people see using hydrogen to fuel cars. The list goes on. Dwight

It would be really cool to sit at the console of a Univac and run some calculations on it, watch the power meters twitch as the accumulators spin. Maybe run the infamous election prediction algorithm :) Running an actual Univac, however, would be cost prohibitive, in electricity alone if not in maintanance. Get a Univac all set up, maybe with just enough B+ to get some of the heater elements lit up for show, complete and in working order, mind you. But if people want to play with one have an accurate simulator set up, driven by a PDP11 or Palm Pilot or something equally humorous. It would clearly be marked as a simulator, but you'd get the full effect of operating a Univac. Maybe even have it blow a tube now and then :) _________________________________________________________________ Express yourself instantly with MSN Messenger!

"Error: sysboot not found"

by sab＠freemail.ru

Hello, Aro Hirohi I found your message releted to sysboot problems at Apollo DN5500 . here it is ____________________________ I am trying to salvage a nice Apollo DN5500 server. Unfortunately I had to swap the original Maxtor ESDI 760 HD - it makes a clunky noise - for a lower capacity Micropolis and I have some difficulties to reinstall DomainOS software. The system starts under service mode. It can read a bootable tape and install the mini DomainOS software but it cannot boot DomainOS directly from the hard disk ... it dies with an "Error: sysboot not found" What I've done ... in service mode, with a 10.3.4 boot tape inserted, > re > di c > ex config, ex calendar, ex invol ... to enter the new hd configuration, setup date/time and format hd then ... > ex domain_os ... does a lot of shoeshinning, copy base OS from tape to hd and says that sysboot is found and skipped ... ) go ... goes to HP logo and login or ) sh runs a text shell ... I was delighted ... but now if I shutdown and reboot the system in normal mode, it passes the tests ok but fails to start the base OS complaining about "sysboot not found". Same result in service mode if I do a > re and > ex domain_os. Considering that it boots fine from a tape, I assume that the sysboot is not a eprom program and that it has been erased by formatting the drive. Does anybody know how to install the sysboot. Does it have anything to do with the 40KB file copied from the tape to //nodeXXX/sysboot on the hard disk? Kind regards, Aro http://www.classiccmp.org/pipermail/cctech/2003-December/023001.html ______________________________ I have the same problems now. Did you solved your ones ? If yes - may i ask you how you did it ??? Thank you. Al.

I'm surprised nobody has thought of the obvious: mercury is considerably denser than glass, so the glass would float on the surface. All you have to do is skim it. Never mind skimmed milk, Sellam, you can have skimmed quicksilver ;-) A more interesting way would be to use some other metal to make an amalgam, leaving the glass behind, and then recover the mercury from the amalgam. Sodium's good. If you put sodium amalgam in water, it will decompose into nicely fizzy caustic soda solution and pure mercury, giving off hydrogen, which "burns rather readily". The usual method of filtering mercury is to use a small folded filter paper, with a very small hole torn in the point of the cone. The mercury will run through the small hole, but most of the rubbish, which floats on the top, will stay behind. You usually need to do this a couple of times. -- Pete Peter Turnbull Network Manager University of York

Hi David;; I had at one time over 20 of those classic radios when I was a kid. Now I only have one, a Stennite. I too have slipped to collecting classic computers and using a PC. I am in Astoria, Oregon, USA and could come up and pick up the lot in Victoria, BC. I am particularly interested in the IMS and the Soroc and would pass any of the ones I wasn't interested in on to other collectors. I have had a couple of Northstar Advantages but never a Polymorphic. I would bring a Toyota Van. How soon do you need to move them? Paxton Hoag Astoria, Oregon

Fwd: survived another one!

Glad to hear that you're still with us Joe! So, how 'bout them hurricanes ;P ? By the way, you wouldn't happen to know how bad (or good) NHC did with the forecast? I'm only asking because I work over at JTWC (Joint Typhoon Warning Center) here in Pearl Harbor, and we just love to make fun of those guys over there. It's funny that they say they're busy over there when there are only two storms. 2+ storms are the norm for us! And we don't get an "off" season (don't forget about the southern hemisphere!).

Second hurricane in three weeks!! Just got power back after hurricane Frances. This one was HUGE!!!! It reached from the FIorida Keys to Atlanta Ga! It started raining here Friday. HEAVY rain and winds all day Saturday and Sunday. More rain Monday (and a curfew in effect). Today (1:30 PM Tuesday) some rain bands are still passing through. Three tornadoes in this area yesterday and another today. The worst of the storm was south of us this time and everything around here that could be blown down was already down due to Charlie so now as much damage this time but HUGE amounts of rain. I set my canoe outside last week and it was FILLED completely full of rain by Friday night. Luckily Florida is flat so rain doesn't concentrate much. NOW it looks like we're in the path of Hurricane Ivan!!! It's scheduled to be in this area about Sunday or Monday. UnF***ING believable! joe

The large Fujitsu SMD drives (smaller capacity than an Eagle, but about the same physical size, 14" platters) have perspex HDA covers, and you can see the heads moving quite well. I have an M2284 like that. Of course, you can do it with a 5.25" winchester or even a 3.5" one as well, if it's the type that has a flat top cover (note that some Seagate 3.5" drives have a flat *baseplate* to which all the gubbins are mounted -- it looks like just a cover, but it isn't). Just take off the cover, and use it as a template to cut out and drill a perspex replacement. Or even cover it with clingwrap (saran wrap, I think you colonists call it), but keep people's fingers away from it. -- Pete Peter Turnbull Network Manager University of York

Atari to release "new" hardware - the 7800!

by cbajpai＠comcast.net

For those of you who were at VCF/East and saw the talk from the developers of the Atari 7800..while they may have been disappointed the 7800 wasn't smash hit in ~1985.it may be in 2005! Atari (Infogrames) is releasing a miniaturized 7800. I wonder if any of the original developers will see any cash from their efforts 20 years ago. -Chandra Atari to Reissue Scores of Old Games By ANTHONY BREZNICAN AP Entertainment Writer LOS ANGELES (AP) -- Atari wants to take you back in time, and to get there, you can ride a "Centipede" or an "Asteroid," or bounce back and forth between the pixilated paddles of "Pong." The video game company told The Associated Press on Tuesday it plans to reissue scores of its classic titles from yesteryear on a single disc that can be played on the game consoles Xbox and PlayStation 2. "Atari Anthology" will feature 85 games and is scheduled to go on sale in November at a cost of about $20. But it's only one of the nostalgia projects Atari will push into the market then. The second is Atari Flashback, a slightly miniaturized version of the old Atari 7800 from the mid-'80s. It will have 20 games built into it, including "Breakout," "Solaris," "Crystal Castles" and "Battlezone." Flashback will sell for $45 and include a pair of old-school joysticks. Atari isn't expecting its decades-old games to compete on a technical level, like "Grand Theft Auto: Vice City," "Halo" and "Madden NFL 2005" that feature colorful realistic graphics, fast-moving 3-D action and the freedom to roam at will. Instead, the company is aiming at the nostalgia market. "It's a time machine. You go back to your childhood and you play," Atari chief executive Bruno Bonnell said. And for gamers who weren't even born when the first PlayStation appeared? "The kids will think this is quick, this is fast to understand, and we don't need a manual to understand it," he added. "We're going after two generations." Even "Pong," perhaps the most primitive of the games with its simple white square bouncing across the screen, may still have some appeal. "The more primitive the better. It shows that video games are not just about high-end graphics or sophisticated representation. It's about the game-play, the challenge to the player," Bonnell said. The "Atari Anthology" disc will offer new twists on the games, too: "trippy mode," which renders the graphics in psychedelic colors, and "time warp" and "double speed," which can alter the pace of on-screen action. Besides its array of classic Atari 2600 and 7800 titles, the Atari Flashback console will include one previously unreleased game: "Saboteur." Reissuing classic games in the modern consoles has become common over the years. "Sonic the Hedgehog" and its sequels from the early 1990s turned up on Nintendo's GameCube, and the old martial-arts challenge "Street Fighter" series returned on PlayStation 2. But those titles still look like science-fiction dreaming compared to the jumping dots and boxes of the old Atari games. Still, there is a market for even those old games, and the Internet proves it: Countless sites offer free downloads of the programs for playing on PCs - leading to rampant bootlegging. But Bonnell downplayed the impact bootlegging could have on sales for "Atari Anthology" and the Atari Flashback console. "You're right to say that a lot of them are bootlegged, and the code is not the right code, and the color is not the right color. But here we're offering them ... and you don't go through collecting the games on the Internet and being scared of the viruses that are going to pollute your computer at some point." Despite their simple appearance, the games can be very difficult, he added - especially for people who are two decades out of practice. "They are not easy to master," Bonnell said. "Some people believe that because they are old games they will finish them very soon. But I think people will be sweating to finish."

Classic computers FREE to a good home!

by dnr＠horizon.bc.ca

Hi! I'm new to this list, so please humour me. When I was a young lad, my dad, who was in the Radio business from 1925 onwards, lamented the loss of hundreds, if not thousands of classic radios. During the depression years, they robbed the old ones for parts and burned those beautiful wood cabinets for heat. With this in mind, I have kept/collected several old computers... all from the pre-Apple era. These include an IMS system (w/5mb HD!), 2 North*Star Horizon's, and (I may keep this last one) a Polymorphic 88. Terminals are by Morrow, a Lear-Siegler ADM-3A, a Cybernex L46006 and a Soroc-IQ-120. I even have and early Compaq luggable. The POLY-88 and the two N*S Horizons were my own machines. Now, sadly, I use an up to date PC. BTW: The Poly-88 is fitted out with dual N*Star floppies, but I do have the original serial cassette interface card! Now, I am moving and can no longer afford the space, so I wish to give them away - to someone who will appreciate them. They're too good to take to the dump. All were working when taken out of service... all have been stored indoors, and dry. All in very good nick. I have most of the diskettes (mostly 5 1/4" sizes) and original documentation. I also have a large box of spare S-100 memory and I/O cards (Even a clock/calendar on an S-100 board!) and various spare drives - in both 48 track SS & DS and 96 track DS - hard sector. Also have (if I can find it) a copy of McDos which grafted 96tpi floppies onto N*S Horizon disk systems. I think I may even have a printout of the source code for it! (No guarantees on that one!) I also have some old Borland publications and some original CPM documentation. Sadly, too much to keep and move. :( Ah! I hear you say... what is the catch? And, yes, there is one... and it's a biggie! I am in Victoria, B.C., and am not in a position to pack and ship. So, this offer is really only good for someone in Western Canada or the North West USA, who is willing to drive over and collect the stuff. The second catch is that its available only as one lot. Sorry, no time to get involved with 6 people who each want different bits. If you're interested, please reply off list, please. Many thanks. ---------- David Young, | ?galit?, libert?, Victoria, CANADA | fraternit? et Beaujolais.

Keyboards & Conductive Rubber

by dave04a＠dunfield.com

Hi Guys, I'm trying to revive a keyboard (integrated into a vintage computer so it's kinda important) - this is the kind where there's a PCB with lots of "pads" in the scanning matrix, and the keys push a little pad of "conductive rubber" down onto the PCB pads to make the connection. Several of the keys on this keyboard require excessive pressure to make contact - I've tried cleaning the pads, and (gently) the surface of the rubber, however it appears that the rubber has increased in resistance. The good keys measure 200-300 ohms from one end of the conductive rubber pad to the other with only mild pressure - the bad keys measure 5k-10k unless you really squeeze them - under pressure they drop to 1k - 2k, which appears to be barely enough to trigger a detection. Anyone know what the failure mode is? I though perhaps the rubber bits had cracked, however this does not appear to be the case. Anyone have any tips/tricks to fix this problem?
