Pressed Particle Board Shelving Warning

by rdd＠rddavis.org

In case anyone else on this list is using steel shelving with particle board shelves that's been in use for over ten years, and hasn't given the shelving a careful looking over, it may be a good idea to do so. When looking for shelving to stack lots of equipment on in the early 1990's, I purchased some shelving from Sears Roebuck & Co. that was rated at least one ton per shelf. The steel framing is very heavy, but at the time, I was a little wary of the pressed particleboard shelves themselves, but was told that they would hold the rated weight. For the past ten years, I've been quite pleased with the shelving, until now. While there's nothing extremely heavy on the shelves - e.g., one shelf contains a Canon laser printer (the square one with a CX engine), about 40 full-height 5-1/4" hard drives, an 8" floppy drive and a few other things, I noticed that some of the items on some of the shelves appear to be leaning slightly. It turns out that the boards are sagging a bit towards the center, so it's just a matter of time before things begin to go crash. Not sure how soon that might happen, but this sagging has occurred fairly quickly, or so it seems. No other space to store some of these things, so, I'm just hoping for the best until I can make other arrangements, but 3/4" oak planks, which I'd prefer to use for adding some support, have become quite expensive. Replacing the particleboard would be a major pain, since the entire shelving assembly would have to be disassembled. So... in case anyone hasn't checked their shelves carefully lately... Note: part of this is most likely as much my fault as the manufacturers', since there is some occasional dampness near the shelves, but, for years, there was no apparent problem, and no obvious rust, mildew, etc. on any of the equipment. Not much I can do about the dampness, except hope that repainting a basement stone wall with some new waterproofing paint will help things... thanks to BG&E, Baltimore Gas & Electric Co., for disturbing the wall, thus causing increased water leakage during heavy rains, when they pounded heavily on the wall while lining gas pipes in the area and installing a new meter a few years ago... I should have tried the aforementioned repainting a few years ago as well. Procrastination: not just a skill, a way of life!

Beige TI99

by witchy＠binarydinosaurs.co.uk

Hi folks, Anyone come across a beige TI99/4A before? I'd previously thought all beige machines were early TI99/4s but last week I was sent a boxed 'Texas Instruments 99/4A' that's very beige and hopefully very working....not had a chance to test it yet. In other news I'm celebrating one month at my new job; it's great to be back in a fully equipped workshop with 'scope access and loads of DEC stuff amongst other things, so once I'm settled in my new weekday flat (I come home at weekends, a nice 500 mile round trip) I'll be able to take dead machines down for repair...... -- Adrian/Witchy Owner & Webmaster, Binary Dinosaurs www.binarydinosaurs.co.uk - possibly the UK's biggest online computer museum www.snakebiteandblack.co.uk - ex-monthly gothic shenanigans :o(

Wanted: M9312 ROMs

by Lee.Davison＠merlincommunications.com

> I don't know what spped the M9312 PROMs are rated at but I was just > looking at my notes about the Bipolar PROMs used in the HP 1000. > They're rated at 60nS. Can you get EPROMs that are that fast? No and yes. Worst case timing for a typical 256kbit EPROM is 150ns but if you know the address will be stable at least 150ns before the data is required then the delay from /OE to valid data can be as little as 40ns. Also if you know which address lines cause the greatest delay then you can avoid switching them and operate the with a worst case delay of about 75ns. I would guess that, with care, 120ns parts could work and that 90ns parts would work in place of 60ns bipolar PROMs. Lee. ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.

ftp vs http vs scp

by pete＠dunnington.u-net.com

I recently had a discussion with our security advisor at work, about FTP being replaced by HTTP and SCP. Some people would like to replace "insecure" FTP with "modern" services like SCP and HTTP (something along the lines of "we don't do anonymous FTP, stick the file on a web page instead"), and argue that they're safer and there's no loss of functionality. I'm not so sure. For example, FTP understands the difference between a unix-style "stream of bytes" file, and a structured one such as might be found under VMS (or any of several other OSs) -- and can deal with the difference. I don't have an easy way to test this, so I don't know if web browsers or programs like wget can do the right thing, or indeed if servers such as Apache can, or what happens with SCP -- but it occurs to me that it might matter in the context of classic computing. Anyone? -- Pete Peter Turnbull Network Manager University of York

Austrailian Computer Museum call for help

by vcf＠siconic.com

Just got this: 1. Expressions Of Interest =+= DISPERSAL of Computer Museum Collection. ========================================================================= The Australian COMPUTER MUSEUM Society Inc has been actively collecting local artefacts for the past ten years. It now has amassed a collection that has been estimated at nearly 50,000 individual items. The ACMS has recently had to relocate from its sponsored stored space at Kennards at Homebush and cannot afford to pay the commercial rents required for the 1,000 square metres that the artefacts occupy. The ACMS collection consists mainly of electronic computing items with associated media, software and documentation, plus a lot of ancillary equipment related to office automation and communications. Expressions of interest are being sought from any Regional Museum or similar organisation who could store and/or display any of our duplicated items. Most of these would be from the 1970s and 1980s and are all systems that were in use in Australia. A typical set up would be a mainframe or mini-computer style system (with flashing lights on the front), storage devices (such as disk and/or tape drives), printers and visual display units; as would have been used for corporate record keeping and business management. Smaller systems that might have been used for word-processing in a small professional office are also available. Some specialised scientific, engineering and medical application systems are also available. The ACMS is not in a position to pay for freight to distant locations (but other grants may be available for such purposes); however we may be able to assist with historical notes and possible contacts with users. Any assistance with sourcing space for our repository would also be highly appreciated.

Midi soundblaster direct connect?

by melamy＠earthlink.net

to add my comments, if you are concerned about compatibility, you are probably listening to a saleman that wants to sell you a USB to MIDI adapter. I walked into a music store a few months back and was asking about such things. The salesman proceeded to tell me that computers don't have midi interfaces anymore and that I would need to buy something from him. I have put together many systems over the years and I had yet to hear of a MPU401 problem and I had thought they had basically become standard because of the Creative Labs SoundBlaster. I have a ASUS 4C800 MB (800mhz FSB, 1.8G cpu, sound, & ethernet on board). I went home, checked the ASUS site and all I needed to get was a game port adapter for it to bring the midi out. That cost me around $12 on eBay, I installed it, pulled out my handy game port to midi cable adapter (same one you can get on eBay for around $18), connected up my Panasonic keyboard, and ran the software that I had bought called ("Instant Play Piano" at Costco.

Midi soundblaster direct connect?

by jimmydevice＠hotmail.com

Is it possible to attach ( with a proper connector ) an "isolated" midi device directly to the soundblaster midi joystick iinterface? I don't feel like building a full opto isolated pass through interface for this little keyboard. Just midi in to the computer is OK. BTW, this is on topic, the KB is over 10 yo. Thanks, Jim Davis.

Discharging CRT anode and capacitors on a VT52 DECscope

by wacarder＠usit.net

I recently acquired two VT52 DECScopes and I am ready to begin the troubleshooting process. I've never attempted to troubleshoot a CRT device before, and I don't want to get blasted across the room if I do something wrong. Has anyone here worked on these types of terminals before? I'm finding conflicting info on the proper method of discharging the CRT anode. I have turned both of them on. One lights up with random patterns, no cursor, and a clicking sound. The VT52 maintenance manual indicates that this is likely a problem with the anode clip or anode cap. I'd like to move on to the next step after I make sure that both the clip and cap are secure. Can an "expert" here provide some proper directions on how to discharge the anode and capacitors? How long do these things on a charge? Ashley

VT52s wanted

by wacarder＠usit.net

Does anyone have any dead DEC VT52 terminals they would like to donate to my cause? All clues are now pointing to a bad RUT module on *BOTH* of my VT52s. One RUT module causes the CRT to do random things. The other one, which is much more well behaved, lets me get the flashing cursor that I should get, but no keyboard input is displayed and there are no keyclicks. I suppose I could go through the individual components of the RUT board one by one and replace them to see if I can get anything to happen. Before I do that, I am going to do some more research. Back to studying the detailed technical documentation in the VT52 Maintenance Manual. Ashley

Lear Siegler ADM-3A CRT problem

by elf＠ucsd.edu

Hi folks, I've had a Lear Siegler ADM 3A terminal in storage (a closet) for a number of years, and recently went to pull it out. Much to my disappointment, the CRT now has some problems (_physical_ problems, not electronic). When I originally stored it (about 4 years ago), all was well. But now there are bunch of "spots" peppering the outer perimeter of the front of the CRT. These spots are NOT on the surface of the CRT (i.e., it is not a "bubbling" sort of phenomenon), but rather behind the outer glass. Here are some pictures: (approx. 35K each) http://home.san.rr.com/instep/adm3a-crt.jpg http://home.san.rr.com/instep/adm3a-crt1.jpg When I power the terminal up and type some characters, they are all perfectly readable when located away from these spots (i.e., towards the center of the screen). But if the characters are positioned behind these spots, it is as blurry as hell. 1) What's happened to my CRT? Is this symptomatic of a slow air leak? Or is this mold? (it sure looks like it! :-) 2) Can the CRT be fixed/repaired? (my guess is no) 3) If it (the CRT) can't be fixed, does anyone know a source for a new (or used) one? (It is a "Ball Brothers Inc." CRT) Kind regards, Eric

Computer flooring/flooding/water in computer rooms

by mmcfadden＠cmh.edu

Flooded computer room Our computer room was on the 11th floor of an office building. The cooling was based on a unit that used the cold water feed into the building as a cooling source. The air handler was in the computer room also included a humidifier. The float valve on the humidifier stuck and flooded the room under the floor. We noticed/felt "high humidity" on Monday morning. No water was visible. We pulled up a floor tile and there was 2 inches of water under the entire floor. All of the cables were in water. Most of the terminal cables were threaded through the channels in the floors to other offices; all of the channels were also full of water. Everything was still running. We got a dehumidifier, pulled up a few floor tiles and dried the room out. We placed rag wicks down in the channels to draw out the water so we could evaporate it. All of the cables were covered with dust, grime and rust colored crud that dried on them from the water. Mike

Pressed Particle Board Shelving Warning ( computer floor)

by mmcfadden＠cmh.edu

I have a pile of computer flooring setting in the corner of my garage. The hospital removed it and I'm hoping to set up a computer room. My wife keeps asking about when and where. Tiles have a black rubber/plastic edge about ? inch wide on all edges. Center is tile/hard linoleum. Structure is steel with an x pattern on the bottom. Very heavy. The tracks to support the tiles are metal channels with a cross section -------/\------- | | | | | | ----- ----- This lets the tiles abut without sliding across. A foot can then be clamped into the channel and leveled. Our feet were all epoxied onto the concrete subfloor. I have several that are cut to allow cables/hoses to penetrate the floor. You can see the cross section easily. I have seen versions with carpet squares on them. The only problem with the suction cup tile pullers is that picking a tile up at an angle can result in dropped tiles, they loose suction. Mike

More precisely, it has hooks that can be enabled at compile time: if you compile with -DUSE_SSL and link with the SSL libraries, you'll get SSL-capable Lynx. This is not a new feature, as I (deliberately) use a very old version of Lynx. In 1997-98 I was on the Lynx development mailing list and saw their development process. That was right at the time when Foteos Macrides (Fote), who maintained Lynx from times immemorial until version 2.7.x, was retiring from Lynx development and passing the baton to the new gang. I was personally very displeased with what the new gang did to Lynx (there were many issues, but the absolute show-stopper for me was when they replaced simple Makefiles with the GNU autoconf morass), and I chose to forever stick with Fote's last version (2.7.2) plus my own small changes. My version of Lynx (2.7.2MS) lives on my FTP site: ifctfvax.Harhan.ORG:/pub/net/www/lynx I didn't have to do any special work for SSL, since SSL was already there when I picked up Fote's last version. > in each case, I got > about four levels deep in tools-to-build-the-tools before running into > a requirement for something ridiculously heavyweight - perl, I think - > and abandoning the attempt. The SSL libraries were a pain to build under pure 4.3BSD, but I succeeded, and it was just usual compilation pains (fixing code that assumed "modern" C, headers and libc), no special tools like Perl required.

Extracting files from TPC RSTS/E Tape image?

I've got some RSTS/E backups that have been converted to TPC format tape images, and I'd like to extract the files to a Unix system. Are there any tools to do this? Zane -- -- | Zane H.

Wanted: M9312 ROMs

by GOOI＠oce.nl

In an effort to beat Al, :-) I have a website page that deals with the M9312, and the PROMs: www.pdp-11.nl/ Click on the PDP-11/34A folder, the CPU information folder, the options folder and then on the bootstrap link ... It describes the installation in the various PDP-11's, the jumpers and DIP switch settings and the PROMs. The PROM id's are links ... Come to think of it: a description how to read the PROM when it is socketed in the M9312 for identification purposes would be a nice addition. hope this is usefull, - Henk, PA8PDP > -----Original Message----- > From: Joe R.

If they aren't already in PDF form, why not send the manuuals to Al and have him scan them - he's got a great scanner!! -- PLEASE! esp the V4A sysmgr manual, which is needed to revive the dectapes that were read. I can turn these VERY quickly and would be happy to cover postage both ways.

Help identifying AppleII cards?

by dave04a＠dunfield.com

Picked up a IIe today - has a couple of cards in it that I have not seen before... #1 ISAAC INTERFACE BOARD D91A-8318 REVC Copyright 1981 by CYBORG CORP Large format card (large enough to slope down at front) Has an 6522 on it. Also has an external battery box that plugs into a small barrel jack at the front of the card. Has 6 pin terminal strip, plus two 34 pin ribbon cable headers. Small 4-position DIP switch at front, 8-position DIP switch farther back (under terminal strip). #2 No markings at all. Smaller card, slightly longer than Apple disk controller. Has a 20 pin header sticking out the back of the card. Has an RCA 1802 CPU on it! 2 2k EPROMS 1 6 position DIP switch. Anyone recognize these?

Digitizing Datapoint 2200 cassettes

by aek＠spies.com

I received a non-working (anyone have the service manual?) 2200 this past week with 15 cassettes and some manuals. The manuals are now up on Bitsavers, and I tried digitizing the cassettes using the audio input on one of my macs. Looks like it should be decodable in software even though it's slowed down from the normal 7 1/2 ips tape speed. If anyone has any other tapes, I'd be VERY interested in trying to decode the data from them, and also scanning any other manuals that might be available.

Chicago test equipment sale

by jack.rubin＠ameritech.net

This was a great sale - luckily Dan V made sure I didn't have to worry about starting a collection of HP desktops - given my packrat tendencies, smaller is definitely better! Here's what I brought home - - MMD-2 Microcomputer Design set - pretty sure Jon Titus was _not_ involved with this model, but I'm looking forward to talking to him about it at VCF-East - 4 HP 1611A Logic State Analyzers, each with a different interface option - Z80, 6800, 6502 and "generic" - box of HP 1630 Logic Analyzer General Purpose Interfaces (6 10269A, 3 10269B), all with the 6809/6809E personality card and half of them with 6809 chips still in place - F8 microprocessor probe (HP p/n 01611-62104) - box of 14 early 1970's Data I/O Programmer interface cards (1702/2102 vintage) - Xerox 2700 PAR-EBCDIC 64K cartridge (p/n 9R22283 101S04653) - 2 shrink wrapped boxes of 8" Wabash disks - boxed copy of Lotus 123 - big box of '70s dated ICs, transistors, caps, ferrite beads, trim pots, resistors, etc. - many Motorola parts (much of the equipt was ex-Moto) What I missed - what Dan got and a Pachinko game. It was great to meet Dan and chat; I missed him in Dayton, but hooked up with Dan Cohoe there, another good guy. If anybody is interested in the F8 probe or Xerox cartridge, they're yours for the shipping cost (both are small). I'd like to get $10 each for the HP 10269x/6809 interfaces - I'll put them on VCF if noone here is interested. Jack

Cheaper solution: get 2 or 3 lengths 1" square steel tube (Dexion Speedframe or equivalent), drill 3/16" holes through them every 12" - 18", and screw them to the underside. That'll stiffen it enough. I've got some benches that are made rather like like that, and I can stand on them without them sagging. -- Pete Peter Turnbull Network Manager University of York

VT52 restoration progress

Thanks to the list members who gave me advice on discharging the CRT on the VT52. I have made progress on getting one functional terminal out of two dead ones. By using the VT52 Maintenance manual, I have done some troubleshooting and have one terminal displaying the flashing cursor by doing some board swapping. Now I have to get it to display characters as they are typed on the keyboard. Ashley

Greetings -- The diskettes are here, so here are the details: Certron brand, retail packaged. 10 diskettes per box, with inner plactic sleeve and labels. Still shrink-wrapped. I opened two boxes and formatted 6 randomly-selected diskettes without incident. They look and act brand new. They are packed in two different size cartons: 10-box and 42-box. Weight on the 10-box cartons is 4 pounds, and the 42-boxers are 22 pounds. I'm in Orlando FL, zip code 32810. Price per box is $1, minimum 10-box shipment, plus shipping. I'd prefer to ship UPS but will ship USPS media mail upon request. I can accept VISA, MasterCard, American Express and Discover, but we're flexible here so if you have another preferred method of payment let me know. I *think* I have replied to everyone who said they wanted in on this deal, but if I skipped you, send me an email, either here or at glenatacme(a)aol.com. I'll get back to you privately with our toll-free 800 number so you can call and arrange shipping and payment. Any other questions, let me know. Later -- Glen Goodwin 0/0

>> But I got to wondering what is the strangest thing that anyone has >> ever found inside a computer or similar piece of electronics gear. >Spiders and I saw a computer (well, a PeeCee) that was used by a mouse >or similar rodent as a toilet... Not so unusual, I guess, but I opened up my PDP-8/L and found a large mouse nest complete with mother and three jellybean-sized babies nursing. She ran away dragging them from her nipples. Just as well, I wouldn't have had the heart to kill them anyway. I also had a home-built S-100 system when I lived in an apartment. There were occasional roaches. One day I noticed a roach or two running into and out of the computer case. I lifted the lid and saw literally HUNDREDS of them, heading in every direction including up my arm. I retreated and returned with a large can of insecticide... there was an amazing amount of turds, too. Talk about debugging a computer :) -Charles

Hi Yes, the ground/commons do need to be connected. The receivers only have so much common range that they work over. These are more tolerant of ground noise but they have limits just as well as any solid state device does. You absolutely need to have a reasonably good common ground. As I recall, they are spec'ed as about 7 volts common noise and have a maximum of around 15 volts common voltage. With high power devices or circuits that do are not connected to a common ground, these levels can be easily exceeded. It is best to have a star type ground system to avoid ground loops. If you need true isolation, one should use optical isolators or transformers. Dwight > >-- >One thing I just wondered: in what time zone do you people at the >southpole live? > >Bert >
