Need help with 2 projects. (TI and Xerox)

by g-wright＠att.net

Hi, All I am looking for repair manuals for a TI 990/12 Business system. mine has no output from the Power Supply board. Fans come on. I have dozens of manuals but all have to do with operations and software. The only service info. is a folder with full of Xerox tech call logs and reapir invoices. The second machine is a Xerox Star. I have the software and operating manuals. I would like to find the stand alone common software disk or a disk image. I have only the network disks and booting it with out the network server is a pain. Of coarse if someone in the Seattle area has a Xerox 860 server they want to part with I can have my own Xerox network and Space heaters. ;-) I would also like to find the sys admin. type manuals. (set up, software install) Thanks, In advance Jerry Jerry Wright JLC inc. g-wright(a)att.net

I have an AS/400 in my trunk...

by ian_primus＠yahoo.com

I was really busy over Thanksgiving, and then I got really sick, I'm just recovering today, so I haven't had much time to do any tinkering with computers. I just got home a few minutes ago, and the back end of my car is sagging from the weight of an IBM AS/400 Model 9404. It's very heavy, and I can't lift it alone, so it's going to have to stay there until I can get a friend to help me lift it out and get it into the house, but I have the panels, tape drive and battery backup unit inside (I took them out to make it lighter and easier to load). Unfortunately, the machine is missing it's hard drives, as well as their carriers. It does, however, have a tape drive installed, and seems to have it's full compliment of boards. I can't wait to play with it :). It's not like I need another project, and I really don't have space for it at the moment, but I couldn't pass it up. I can always use it as a nightstand/space heater... Anyway, anyone know anything about this beast? I've only done a little googleing, which hasn't turned up any information on the hardware. I need to find at least one drive carrier, and an operating system for it. Does Linux run well (if at all) on the AS/400? Like I said, I haven't done much research yet, I'm just trying to see if anyone has had any experience with this thing. It's an interesting (and heavy) piece of hardware. It will be fun to get running, provided I can find the time. Ian Primus ian_primus(a)yahoo.com

Foam replacements

by RCini＠congressfinancial.com

Hello, all: The other day I pulled my Radio Shack Model 102 out of the hard plastic case and noticed, for the first time, that the foam padding is starting to deteriorate. Does anyone have a source for replacement foam sheets or the like that I could use to replace the foam in the plastic case? I don't have the measurements handy, but it might be about 11" by 18" in size and 2" in depth. Any thoughts appreciated. Thanks. Rich

IBM 5216 printer

by Innfogra＠aol.com

My bad. What I was remember was the 5218 not the 5216. Do you have a picture? My memory is not what it was, especially for non favorite printers. >From the IBM info I would say this was the Wheelwriter printer that was concurrent with the PS/2 line of computers. It was also related to the Wheelwriter series of typewriters, the last, I think, being the Wheelwriter 7s. If it has a parallel port it is this daisywriter printer not the older one. What ports does it have again? Paxton Astoria, OR

Space Invaders returning to arcades...

by RCini＠congressfinancial.com

Interesting clip. I hadn't seen it before. At least this is the real game. If you look at Hammacher-Schlemmer and the holiday issues of similar catalogs, they are selling multi-game units (like Galaga and Qix, MacMan/Ms. PacMan for example) for $3000. I've seen these hybrid games up close at the Fortunoff store near me and they're smaller than the real arcade games and have crappy decals on the front and sides. Even the coin door on the front is a decal -- not that you'd need a real coin door for use at home. For much less you can build a MAME machine (I have a MAME machine in progress) and have as much or more fun with it. Now, in Namco's defense, parts alone, using eBay and Happ Controls as a proxy, might cost $700 or so. I'd figure that $999-$1199 would be a good retail price.

Hmm, I've got a couple of patch panels identical to the TR-48 shown on that URL. I got them from Los Alamos Sales, Ed had some huge, multi-rack analog computer that got broken up and scrapped. It was huge, probably a dozen racks or more. I took home two panels only. I was going to just hang them on the wall, they're nice to look at.

IBM 5216 printer

by Innfogra＠aol.com

IIRC the IBM DisplayWriter. The cables were thin and came to a non standard D sub 9 pin. There was a cut sheet feeder that might plug into the other port. It has been a long time. I think the System 23 also may have connected to that printer also. There weren't many IBM daisywheel printers. I had a lot of those go through my hands about 15 years ago. Paxton Astoria, OR

HP 2000 BASIC help / TREK73

by Zubla2001＠aol.com

> What does '14 in a PRINT statement, in front of a quoted string, mean > (eg in PRINT '14"SULU")? I wondered if it were something like PRINT > TAB(14)"... but there are TAB()s elsewhere. A control character, > perhaps? If cursor or screen control, are they octal or decimal (I'd > guess decimal) and is there a table anywhere? decimal. The table in the back of the Access BASIC manual is excellent. Another response to this thread (November) listed a URL. Of interest to people pulling apart the HP as well as programmers: My friends and I once noticed using Access functions (CHR$(7)?) instead of the single quote ('7) actually took up more storage room. There was a maximum line length of somewhere between 254 and 256. Using the single quote (for control chars) allowed for much much longer lines. So something is different in the tokenizing and it also explains why a less readable format was used. Although you get used to it. :-) ~Zubla

FAT file system now licensed by MS ?

by RCini＠congressfinancial.com

I think that the 1976 reference may come from the following. Microsoft had Stand-Alone Disk BASIC, which may have been available in 1976 (I don't have release dates handy), used a file system that might have been the beginnings of the FAT scheme. Then, I found this reference in a June 1983 article written by Tim Paterson called "An Inside look at MS-DOS". In that article, there's a sidebar called "A Short History of MS-DOS" (some paragraphs deleted for brevity): "...In May 1979, Seattle Computer made the first propotype of its 8086 microprocessor card for the S-100 bus. There were brief discussions with Digital Research about using one of Seattle Computer's prototypes to aid in developing CP/M-86, which was to be ready "soon."..." The article continues: "Microsoft had already started a strong 8086 software-development program. The firm was ready to try the 8086 version of Stand-Alone Disk BASIC, which is a version of its BASIC interpreter with a built-in operating system. During the last two weeks of May 1979, this BASIC was made completely functional using the hardware that Seattle Computer provided for Microsoft." Continuing: "Seattle Computer shipped its first 8086 cards in November 1979, with Stand-Alone Disk BASIC as the only software to run on it. The months rolled by, and CP/M-86 was nowhere in sight. Finally, in April 1980, Seattle decided to create its own DOS." And more: "The first versions of the operating system, called QDOS 0.10, were shipped in August 1980." More still: "In the last few days of 1980, a new version of the DOS was released, now known as 86-DOS version 0.3. Seattle Computer passed this new version onto Microsoft, which had bought the non-exclusive rights to market 86-DOS and had one customer for it at the time." "In April 1981, Seattle Computer Products released 86-DOS version 1.00, which was very similar to the versions of MS-DOS that are widely distributed today." So, who invented the FAT filesystem we know today? Microsoft (through Stand-Alone Disk BASIC)? Seattle Computer (through 86-DOS)? To paraphrase Artie Johnson..."Very interesting".

First of all, the patents referenced on their FAT licensing website: http://www.microsoft.com/mscorp/ip/tech/fat.asp ...are for long filenames. They have no patent on FAT, and for good reasons: 1) software patents were not allowed at the time that FAT was implemented in MS-DOS, and 2) FAT was basically lifted from another OS. I have no idea why MS would be so stupid as to think people are going to fall for this, which is basically a sad-assed ruse. Also, I highly question the history they are promulgating. They claim they developed FAT in 1976. That seems a bit early. I could be wrong.

The AS400 was primarily for RPG and COBOL, but did have other languages. In fact it had C, but I was never quite sure how a ported C program would work with their batch-IO to terminals...

BreezeNet data/power modules

by vcf＠siconic.com

I have a number of BreezeNet data/power modules. This is a two module set that allows you to run both data and power over a CAT5 cable so that you can power, say, a WAP in a weird location where there is no power for it. It comes with a power supply that puts out 15V AC @ 1.8A (input = 100-240V). The power supply plugs into a "local" module with data in and data/power out. You then plug in a CAT5 cable from data/power out to the "remote" module. The remote module has a data port (which you plug your WAP or remote router into) and a power out jack. Very nifty if you need to bring power to a device that has none nearby (like in a ceiling). These are basically new in the box. I'm asking $5 each plus shipping.

FAT file system now licensed by MS ?

by MGemeny＠pgcps.org

I think Hans summed it up quite well, but perhaps didn't go far enough with his thought. Hans Franke wrote: >What pisses me of most is that they want licence for media if they >are formated with FAT. Beside that this is even more a joke than >the Rambus scam, it sets the stage that not only software (and the >underlaying algorythm) is protected by a patend but also the data >generated by this algorythm! >Let's just continue the idea: Assumeing MS had a patent for some >parts of Word, under the above circumstances, every document written >using Word, stored on a media will be the same ... so does MS own >what I write, because I'm using their programm? So, if I happen to be the manufacturer of digital cameras, and I write a program that rearranges the bits on a flash card that was formatted by a microsoft operating system, and that operating system is fooled by my arrangement of the bits, I have to pay microsoft? Even worse is the manufacturer of media. Who is to say that the manufactured is not using a microsoft operating system to format the media in the first place. So now he has to pay a quarter of a US dollar for each piece of media that he formats with his microsoft operating system. When will this trickle down to charging the end users for each disk they format, or for each document they create? "Well, it's only the big manufacturers they are going after." Right? "In Germany they first came for the Communists, and I didn't speak up because I wasn't a Communist. Then they came for the Jews, and I didn't speak up because I wasn't a Jew. Then they came for the trade unionists, and I didn't speak up because I wasn't a trade unionist. Then they came for the Catholics, and I didn't speak up because I was a Protestant. Then they came for me - and by that time no one was left to speak up." Pastor Martin Niemoller, Dachau, 1944 Quick! Somebody contact the press! Oh, that's right, we're not supposed to talk to the press. ;-} And besides, such a story in the press would probably just make microsoft stock go UP! Now that's a sick thought. Mike.

MOTOR RUN VS. MOTOR START

by Lee.Davison＠merlincommunications.com

> The drawing does look as though it is in series with a > second winding. Then it would seem to be being used to create a rotating magnetic field. In this case too samll a value will lead to a reduction in full speed torque and possible speed variations, and too large a value will reduce the low speed torque (i.e. when the motor is running up). However having said that the value will be a compromise anyway and +/- 20% either way shouldn't hurt enough to notice.

It is, like the capacitor in flourescent light fittings the run capacitor on a motor is (usually) just for power factor correction and it matters not if it's 3 phase or single. The give away is if it's across the supply or in series with a separate winding. If it's across the supply then it's for PFC.

MOTOR RUN VS. MOTOR START

by TRASH3＠splab.cas.neu.edu

Well it's been a while, I just remembered something else about run and start. We used to have to put "motor run" capacitors on all our large equipment (3 phase) to get our power factor closer to one (unity). It wasn't ever used in that situation for creating a second phase, as we were using 3 phase motors. However, this system is a single phase system. I don't think the same issue is being addressed by the run capacitor. joe heck btw, I checked for "motor start" capacitor on google and got a nice place to buy caps. http://www.toad.net/~jsmeenen/boom.html is a nice picture of both types of caps in a pool motor application End of returned message

These are non-polarized. Starting capacitors are usually oil/paper ( newer don't have PCB's ). This is because the starting capacitors require more current that would blow up a run capacitor. Run capacitors are used to help maintain efficiency of the motor while running. They help to keep a rotating field and help to pull the inductive load back to a resistive load from the AC side.

These are special purpose capacitors. If you place a regular electrolytic capacitor into this circuit it would blow up. You can use a pair of electrolytics mounted back to back of equal value and something like a 10 meg resistor in parallel with each to keep them balanced. The capacitor values need to have the full voltage rating each and the value needs to be 2 times the desired value. Dwight

100MFD 55V

by TRASH3＠splab.cas.neu.edu

Motor-start and motor-run are different but the same. A motor-run capacitor is AC and is connected all the time. A motor-start capacitor is connected usually through a centrifugal switch (and starting winding) so it is only connected during spinup. There are many motors that have centrifugal switches and starting windings without caps. and most of the caps used are fulltime, that is run caps. Now, my definitions may not be everybodys definitions, but that was how I was brought up when I did motor repair and rewound armatures. The giveaway was the original spec stated 60 cycle, which is a motor capacitor. run or start is not significant, but if it said 60 cycle, then it cannot be a DC cap with plus and minus. As stated in a previous message, the capacitor "creates" a second phase so you can get the motor to spin. Too little or too much capacitance and the created phase is not in the proper angle to provide the right rotation. again, make sure you get at least the minimum voltage, and getting a cap with more voltage spec is o.k., if you cannot match the capacitance, I think I would err toward more rather than less.

DAP 610 Looking For A New Home

Not SCSI. Maybe some later ones were SCSI, > though Tony is right. SCSI is for a Sun connection. VAX is different. Following is more from the referenced docs: Each node of the machine effectively consists of a single bit processor, optional floating point accelerator and node memory. The DAP 510 is small enough to fit under a desk, while the DAP 610 is housed in a standard EIA rack cabinet. Both DAP models can be hosted by Sun or DEC VAX computers and workstations. The DAP can be connected to a Sun host via the SCSI interface. Connection to DEC VAX systems is via DR11W or DRB32 interfaces. Connection to the Aptec IOC is supported as well as direct connection to VME bus. DAP 510 DAP 610 Array size 32 x 32 64 x 64 Array memory 8 Mbytes 16 Mbytes (max. of 128 or 512 Mbytes) Code store 512 Kbytes 512 Kbytes (max. of 4 Mbytes) Instruction rate 10 MHz 10 MHz host Sun or VAX Sun or VAX Size 17 x 13 x 20 in. 45 x 25 x 38 in. The present DAP systems are third-generation machines which started with a 64 x 64 array originally installed at QMC (Queen Mary College, University of London). The QMC machine, which had an effective cycle time of 250 nsec, proved highly adaptable to a wide range of numerical problems based on partial differential equations. The performance on large-scale Monte Carlo simulations in lattice gauge theory and molecular dynamics was found to be exceptional and, in some specialized applications such as the Ising model, the DAP outperformed a CRAY-1 by a factor of 10.

leaky batteries!

by witchy＠binarydinosaurs.co.uk

Hi folks, Whilst getting an old Videomaster pong ready for sale (even though I know nobody will buy it) I discovered it still had its batteries in from the last time it was used - 1970s by the looks of the batteries - and they'd naturally leaked all over the place. I've tried standard Foamcleaner (anti static, natch) to remove the lovely brown stuff but it's not having any of it. Any tips for removal of this stuff without scratching the plastic too much? cheers, -- adrian/witchy www.binarydinosaurs.co.uk - the online computer museum www.snakebiteandblack.co.uk - ex-monthly gothic shenanigans :o(

OT: webserver choice

by waltje＠pdp11.nl

All, This is highly off-topic, but (imho) important enough to just send out anyway. I am moving the www.pdp11.nl site to a new server, for two reasons: - it is currently on one of our production servers, which must stop (for Dutch taxing reasons.) - it will be moved to the colo room of my isp, who have offered to host it to "help the good cause". yay! So.. new server, then. Since it's a DEC Archive, local friends have made sure I understood (...) how important it was that it'd run on Classic Hardware. Trust me, they've mentioned that to no end.... I ended up deciding on an Intel-based box, rather than a VAX or Alpha, mostly because the box has about 400GB of EIDE-based disk storage, which wont happen in a VAX. I decided against an Alpha for other reasons, so ended up with Intel. New machine is a Digital Server 1206, with (now) dual P2/333, but probably with faster CPU's as soon as I find them... the box can handle up to 533, which means it'll end with P2/466's. It has 512MB of RAM- the mainboard wont support more. Disk space is set up using a mirror volume of two 9GB disks off a Mylex DAC960 for the OS, and then a Promise EIDE controller for the four EIDE disks, which are in RAID5 configuration. No problems there. The real bitch seems to be the choice of which OS to run on it. I prefer OpenBSD for such jobs, but alas, that (a) wont do SMP, and (b), much worse, it doesnt support the Mylex. I just did a test install of Linux on it, and that works, so at least I can set it up. So.. remembering the "which OS" discussion earlier, I need a lean distro of Linux with no GUI crap, including all the stuff one'd need for a dedicated web server. Anyone here (Jay?) have put something together, or, much better, have added Mylex to OpenBSD? ? :) Please reply *off-list* , I will summarize later- we dont want a massive debate here.

Carbonic acid is a very weak acid, and the reaction is firmly in favour of a predominance of CO2 in solution. For the rest, CO2 and water each dissociate just like any inorganic compound in water. You don't really form H2CO3, you form 2 x H+ and CO3--. Similarly, when you have salt water, you have Na+ and Cl-, plus a few hydrogen and hydroxyl ions, not "molecules" of NaCl. It's not *that* hard to turn it into NaOH; a 1.5V battery[1] will add electrons, cause hydrogen to be given off, liberating chlorine as well, and what's left is Na+ and OH-. See, we're back to electrons again :-) </tongue-somewhat-in-cheek> [1] Yes, I know it's a single cell, not a battery :-) -- Pete Peter Turnbull Network Manager University of York

A SIMH Attach question.

by MGemeny＠pgcps.org

JC, I can help with that one. The SIMH docs state: " 3.7.2 User Specified Stop Conditions Typing the interrupt character stops simulation. The interrupt character is defined by the WRU (where are you) register and is initially set to 005 (^E)." If I do a "E WRU" I get "WRU: 005: If I tell SIMH "D WRU 007" that changes the interrupt from ^E to ^G. I hope this is what you are looking for. Mike.

KFQSA docs and MDM (was RE: Help needed:Setting up a KDA50)

Or anyone else ? Yesterday I did another try. The KDA50 works now at address 172150, with the KFQSA removed. The command "show qbus" finally lists the controller. Antonio named I link for KFQSA documents but they don't have documents online for it. How do I have to set jumpers for this board? My VAX4000 found the RA-92, attached to the KDA (DUA0). The userguide of the KDA50 refers to a programm called MDM in order to do some diagnostics with the KDA and FORMAT the harddrive. My idea is to boot NetBSD over Ethernet and install it on the RA-92 (there are no other drives installed in the VAX!). Can BSD find the drive directly, format it and be installed on it, or do I have to need a special programm as MDM to format the drive?

Any tips for removal of this > stuff without scratching the plastic too much? I guess it depends on what the brown stuff is, and where it is. On the case? You could try soaking it in something mildly alkaline, like washing soda, or in sugar soap solution, and see if it softens it. Is this a deposit on the surface, or has it combined with the plastic? So long as it's not actually reacted with the plastic, I find Flash is pretty good.

No, Naval Jelly (or phosphoric acid) is what was originally mentioned. It won't penetrate into the threads of a tightly-fitting screw, and if it did, the phosphate it left behind would be almost as bad as the rust. Break Free isn't a penetrating oil, it's a lubricant with PTFE in suspension. WD40 isn't nearly as effective as a proper penetrating oil. It will *prevent* rust but not remove it -- it's a water displacer. -- Pete Peter Turnbull Network Manager University of York

Colorado 250 MB tape drive

Found this in the rubble, and can't find diddly on the internet about it. ISTR it was tied into the floppy drive controller, and it has the 34 pin header that matches? No other identifying numbers, but I think it might be a DJ-20C. QIC-80 cartridge, maybe? I'd just like to see if it works with my Linux box here or not. Might just delegate to the junk Windoze box instead, if it does work. Any answers? Point me in the right direction, even if it is to the dumpster. LOL Gary Hildebrand St. JOseph, MO

So far, the paint has been on for about 10 years and there is no flaking of the paint caused by rust under the paint. The are some small rust stain lines where the paint is cracked. If it had been any other undercoating method, I'm sure these cracks would have allowed the rust to spread under the paint and peeled the paint off. It is interesting that I never knew what the process was called ( Parkerizing ). I do know it works but often when I talk to other boat people, they don't know what I'm talking about. Maybe I just didn't use the right name. Dwight

CC-Talk sbscription problems / Pageing Jay West

Agreed -- don't use phosphoric acid because iron phosphate will gum up the hole just as badly as any rust. Penetrating oil (*not* WD40 -- the stuff we use over here is called PlusGas) is the best thing to try, or a mineral acid like hydrochloric acid if that fails.

OT: Need resources showing deployments for Linux/Apache/PHP vs. Windows/ISS/ASP

by vcf＠siconic.com

I have a friend who is a total Microsoft zealot. We repeatedly get into annoyingly incredibly pointless arguments over the virtues of Linux vs. Windows. I mean, I know people have religious OS wars all the time but he's so ignorant of the Linux world that it's stunning. I mean, the guy is the smartest person I know, but when it comes to this argument, he seems to argue for the sake of arguing because he has no real statistics to go off of and talks completely out of his ass, or he'll quote one article he read somewhere that said one thing (probably not even what he's arguing) to justify his position. For instance, he says PHP is full of holes and is not professional software because it's written by hobbyists on the side, the language is not clearly defined, and there's no support for it. He says the same about MySQL. In fact, this is where the argument tonight started. He had a web service that crashed because one of his MySQL tables got hosed, so he blamed all his woes on MySQL (he claims he had to use it because the programmer he had do the site only new PHP and not ASP which he would've preferred, claiming that ASP is much more robust, is much better defined, is way more powerful than PHP, etc., which may all be true but his criticisms about PHP and MySQL are so unfounded as to be obnoxious). When I mentioned that MySQL DOES have support (you pay for it just like you do when you buy MSSQL) he finds some other nit to pick, which I then shoot down, so he moves on to another, and another, and another, then starts throwing out dubious statistics, etc. So I know it's completely pointless, but I just want to throw some statistics from neutral quarters (i.e. not Linux Journal, but like Forbes, Fortune, Network Magazine, etc.) showing how many deployments of: 1) Apache running on Linux versus Apache on Windows 2) PHP on Apache vs. ASP on ISS 3) Linux servers vs. Windows servers 4) Growth rates, industry trends, etc. No matter what I tell him he thinks that there's no way that Linux is beating MS in any way, shape or form. As an aside, the extent to which he is completely lost is evident in this anecdote. He's complaining how people can't code in 64K anymore, and when I point out that this trend of bloat is pretty much directly attributable to MS with its programming paradigms and overall bloatiness, he shoots that down like I was Satan for even suggesting it. So anyway, I want charts, graphs, hard numbers, quotes, trends, etc. Any articles that can show the actual numbers of what's going on in the industry with regards to Linux vs. Windows. Simple URLs will do. Thanks for indulging this stupidity. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

I'm also convinced sure that the KDA is masked by the KFQSA. The adress on the KDA has been changed by myself to the adress given by the "config" - command, 1ut unfortunately, the KDA hasn't been detected by "show device". Tonight, i'll remove the KFQSA and the KLESI and make a new try with the default addess (172150).

Nuclear Data minicomputer & more!

by tomj＠wps.com

I will probably make a run up to Los ALamos, New Mexico this winter, and will fetch items I think I can unload on classiccmp fools like me, for cost only of course. I want to pre-inquire on a few though. Ed's got a bunch of Nuclear Data branded items, some CRT terminals I don't recognize, and at least one mini. I thought I recorded the model # etc in my Palm but I can't find it. I was of course gonna take it home regardless, but it's wirewrapped -- and the last mini I had died of creeping bad wraps (a Varian 622/I) so I assume this ND machine is non-operating. The mini will run about 50 lbs and shipping won't be too cheap accordingly. It's been stored for years, out of the weather and dry, but large temperature extremes, and it gets cooooold in LA NM. The ND terminals are heavy, and some have NIM slots in the front (Nuclear Instrumentation Module standard 5V/12V etc buss). Obviously they have fat glass tubes both heavy and delicate. Id' say they have a good chance of operating, otherwise. The COSMAC jobs mentioned previously I will take all of, they'll ship cheap. He's also got a DG Dasher terminal, but it's junk, the side is open and missing, wires pulled off the big card, junk and trash in the print head galley. If there's more I'll err on the side of taking it, inversely proportional to its bulk & weight. I'll at least photo anything else. This trip is still somewhat conjecture, but I've gone up there every winter for the last decade, don't see why I won't this year. I have only a station wagon and I may have a Flexowriter and Tally reader/punch to haul home (ugh, I really don't want to) so space may be limited. Consider this an inducement to get me that flexo timing data so I'll ahve more room in the 'wagon :-)

Friden Flexowriter, interface timing

by tomj＠wps.com

I asked before, but I figured annoying an entire mailing list with repeat queries can't hurt THAT much ... ahem I'm working on a flexowriter simulator (hardware adapter, everything else on the host side), I think I have the PRINT side down, but the input side timing I'm missing some detailed info. Two signals, JL11, and JL12, ingeniously named after their connector pin assignments, begin and end the data-valid phase of a key-press or tape-read. Most Flexo signals are determined by cams on a rotating shaft, but these two I believe are determined by a stack of contacts; one of them, SC7, is required to make last and break first (eg. data strobe). I just can't determine how this switch stack is set up, or approximately how long their periods are, etc. I have no idea if all flexo's adhere to this same protocol. I really would rather not drag home 0.1T of drippy/dusty iron just to figure this out... I have a Friden maintenance manual lent to me by a friend but it's not so revealing of timing, mainly just repair-oriented adjustments. (The whole project will be open source, as is the underlying PIC-based controller I use http://wps.com/products/Model-01/index.html)

I'm surprised -- but I'm sure you're right. > My understanding is that Muriatic Acid is > 33% strength Hydrochloric Acid. Sounds about right. Concentrated pure hydrochloric acid is about 36% w/v; left exposed to air it fumes and gradually loses HCl; common concentrated acid is 32%-33%. Muriatic acid is a technical (well, industrial, really) grade and contains impurities as well as being subject to loss. Be careful with it; apart from its corrosive nature, you know you're not supposed to store it in proximity to certain other things, such as ammonia, bleach, etc? > I used quite a bit of it for cleaning > tin-lead plating when I still owned the printed circuit shop.

Why one should never give an interview

by jontitus＠comcast.net

I sympathize with people who get misquoted and who find incorrect things attributed to them or associated with them. If someone approached you about an interview, as a condition for the interview, always insist on: 1. Reviewing direct quotes such as, Fred Smith says, "Computers made before 1981..." 2. Reviewing indirect quotes such as, According to Fred Smith, computers made before 1981... 3. Any reference to you or your company, organization, etc. If a writer or reporter won't give you the opportunity to review what he or she intends to put into print, decline the interview request. If you go ahead with an interview, insist on taping it for your protection. If your company has a person in a marketing-communication or public-relations role, insist they sit in on the interview to help protect you from misquotes or misunderstood information. Maybe a reporter from the NY Times or the Wall Street Journal won't let you see a story before it goes into print. OK, don't talk with them. Recently, the WSJ did a terrible job of relating information provided in an interview by Warren Buffett, the investor. Buffett wrote to say the article missed the point of his concerns, but the WSJ defended it's incorrect interpretation of the information he provided. Several readers also wrote about the awful job the WSJ reporter did. I trust journalists less and less, and I trust TV journalists not at all.

Help needed:Setting up a KDA50

by cheri-post＠web.de

Hi all, I could use some help on setting up a KDA50-Controller in a VAX 4000/200 as I'm interested in connecting a RA-92 to it (the VAX has no drives installed so far!) so that NetBSD or VMS can run on it. The backplane contains the KA-660 Board with extra Memory (MS650), a KLESI- and a KFQSA-Controller (DSSI), respectively. Typing "config" in the Console-Mode gives out the adress fopr the SDI-Controller, if I type in KLESI, KFQSA and KDA50. I installed the controller directly behind the KFQSA-Board with the address given by config. When I type "show qbus" after powering on the Vax, the KDA50 isn't diplayed. Doing the same routine described above without the KLESI- and KFQSA-Controller brings no result. Can the KDA50 be noticed by the "show qbus" command ? The cycling pattern described in the user guide appears every 4 seconds, that's why I think that the boards work properly. How do I know that the VAX found the KDA50 ? Any hints or ideas? Thanks alot for your help in advance Pierre ______________________________________________________________________________ WEB.DE FreeMail wird 5 Jahre jung!

For a little while, I've been mildly surprised to see that when I reply to posts, I end up generating a reply to both the list and the original poster. This evening I realised (yes, I'm slow :-) It's the cold weather :-)) that the Reply-To: header inserted by the list software has been changed to include both. Is this deliberate? Did I miss a discussion somewhere? Am I opening an old can of worms by even mentioning it? ;-) -- Pete Peter Turnbull Network Manager University of York

I wondered what the brown stuff really is, hence my suggestion to try a mild alkali (good for organic junk, like cardboard-in-battery-goo). Muriatic acid, by the way, is hydrochloric acid. Used for cleaning paving slabs, concrete, etc, amongst other things. > For quite a while, I had a small bottle of Acid Flux that was basically > Muriatic Acid, and it worked like a charm. Actually, it was probably mostly zinc chloride, made by dissoving granular zinc (or old battery cases) in hydrochloric acid. Known here as Bakers Fluid. The raw acid would be too strong, and lose its efficacy too quickly. -- Pete Peter Turnbull Network Manager University of York

Disk hardware emulation, was Re: Grandfather system RTE6/VM?

by aek＠spies.com

> Doesn't ST506 have analogue elements to the interface, and a tight relationship to the host controller with which the drive was formatted? -- With the exception of SMD and ESDI, most small disc interfaces used an analog PLL data separator for read data for the drives. There was a LOT of variation in sector encoding formats (differing ECC schemes, RLL data encoding, etc.) Another problem to consider is how to map sector lengths that aren't 512 bytes onto modern discs.

Here's the Reply-To: I see on your message: Yes, that's the odd thing -- it's not *all* messages. My reply to Witchy earlier showed the symptom, because Witchy's message had both addresses in the Reply-To:. Yours, however, doesn't, and mine didn't. A few others I've replied to also had two addresses, but most seem just to have the list address. I wonder if some people are mailing the list with a Reply-To: already set, and the new version of mailman is adding to it instead of replacing it? Witchy?

leaky batteries!

Hi Neutralizing depends on the type of battery. If nothing else gets rid of the stain, try some bleach. Experiment a little in a hidden area first.
