Atari 800 (was free atari in Sacremento)

by thomas100＠home.com

I had a friend who turned an Atari 800 into a planter. After that, I inherited it for awhile- it still worked. He had spray painted tho' it so I elected not to hold onto it. What always amazed me was this huge aluminum casting at the center of the machine where you inserted the BASIC and game cartridges. That casting must have added significant cost to manufacturing the machine! Hope someone grabs it... they're kinda neat. Thomas

Of all of them the NeXT machine is still by far the most useful / least painful. The Trs-80 Model 16B is the most unique in my eye. I was annoyed by it at first but it was free and gradually began to like it. It's currently running CP/M but I'd like to get the HD back up and run Xenix. The software that came with it made it more interesting... as this stuff was untouchable [expensive] when it was new. Thomas

hard drive data recovery

by maxeskin＠hotmail.com

If you are removing a head arm and working on it, you can wrap everything but the actual connection in clean plastic. I wouldn't expect smoke particles to magically fall off the arm onto the platter, even if the arm is upside down. Plus, smoke travels upwards, and I would expect little of it to settle if you use a fan or something. As soon as you finish soldering, take it back to the clean box, and put it inside to let it cool off or to reassemble (unless it's still smoking). As for doing activities which involve platters, that's a trickier thing. I have no idea what you would do if you had a problem with the motor or the axle on which the platters are mounted. Now, my question. Let's say a single head crashes. This would raise up some dust off the platter, right? Would it be possible to recover the material that wasn't destroyed by the dragging head? What if this deformed the platter? >Serious question. What do you do if you need to resolder a head >connection or something? Do you remove the head assembly from the clean >box, solder it, clean if off with IPA, put it back in the clean box and >reassemble or what?

taking care of bad sectors... easy stuff. Was: Re: hard drive data recovery

by poesie＠geocities.com

well, I personally have never opened up a hard drive, if nothing else because I've never had an extra to pop open (i'm too frugal. hehe.) Regardless, I have found the program "Spinrite" to work great on IDE drives; it goes through and can fix bad sectors, or mark them totally unusable. this really differs from standard formats/etc, because I've been able to take drives w/ 30mb of bad sectors and get it to 0 bad sectors, and still running fine w/ no problems after a year. i believe they are on version 5, i got version 4 for about 20 bucks. This is kind of off-topic and doesn't cover a whole lot of you out there, but when you buy a box of 100 drives that are all "bad", you can sometimes salvage quite a few of them. -Eric

Well, I think that the default lack of floppy drive was a mistake, as was the lack of RAM. I'm not sure what year it is, but I believe 640K was standard by then. Also, I have the Getting Started manual for the PCjr. It's supposed to be a technical reference with specs, and details on how to prepare it for shipping (like in the IBM PC manual of the same name), but instead it has childish junk on how to use cursor keys (it has a little cartridge game called the keyboard adventure, with a little guy that can move around). Techinicians reeely don't like that. >Apart from the IR keyboard, which was a mistake ;-), it's basically a PC >without the DMA chip, but with better-than-CGA graphics.

Homebrew game of "life" computer. (1973) 6. Calculator built from neon bulb "shift register counters". Input is a rotary telephone dial. I think subtraction was "1's complements". (about 1968) Interesting peripherals from late 1970's when I was going a lot. 1. SWTP CT-1024 modified for 64 columns and graphics. Hope to get this working again with some computer. 2. Sylvanhills flat bed plotter. Used DC motors and opto-interruptor wheels which I replaced with stepper motors. 3. Stepper motor 3 axis wax carver. Used cylindrical coordinates. The wax block rotated on a turntable. Literature, including First 7 years of Byte. First few years of Dr. Dobbs, the bound volumes, I didn't keep the individual issues. 2 of the Creative Computer games books. 10 issues of "Computer Hobbyist", I have just found the remaining issues. Documentation for Scelbi 8H and other 8008 stuff. Other construction type books. Various parts, including a box of RTL ic's, 1101 memory's.

Yes, it would be fun to find things like this. I still have the 3 potentiometer "analog" computer I built for some science fair. The Digicomp I cost $5.95 in 1969 from Edmund Sci. Others were various mechanical (Dr. Nim) and electronic NIM players, Computers like "Brainac", and later in 1971, a National Radio Institute computer using 53 TTL ic's. Have seen only ad's. A RCA projects book I have has a "slot machine" built from individual transistors for flip flops, gates, multivibrators, etc. It "computed" the score, so was a calculator of sorts.

empty rack

I found an empty rack today, not sure of the dimensions. It had nothing but rails and a power cord. At the top, it had something like "Camex" in blue letters, I forgot exactly what by the time I got home. Next to the name, it had some kind of snowflake-like emblem. Does anyone in the Boston area want this thing? I will inquire if there is anything more where that came from... ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

by higginbo＠netpath.net

Please do. I'd like to see it, but I would rather keep the original case, or an exact or near to it replica in another material. Doug had a good idea with the chrome look, but I think I would have to actually tool a metal case and get it chromed for it to look good, too much money for me, but it would look neat, maybe with some red glowing lights behind the vents ala Terminator. :) Hmmmm. I do have the empty SE/30 case to practice on, but I just got another idea while looking at my mini-tower 233mmx: Cut out one whole side of it, replace with plexiglass or glass panel so I can see all the goodies inside, maybe throw some little 5v LEDs into it to make it purty... I'm getting too many cool ideas here. I need to stop thinking and start putting this in action.

How many computers?

> I was just wondering, how many computers do all you have out there??? Right. My turn now. Unlike most of you, it seems, a lot of my computers don't work. I seem to acquire faster than I can repair - perhaps because computers are just one hobby among many, perhaps because acquiring computers is relatively easy... I have about 60. Last time I counted I got to about 51 but I don't think I got them all. A selection: Assorted PETs, at least one C64 and a couple of VIC 20s (one with missing keytop); Assorted PDPs in various states of disrepair, plus a large number of spare M-series boards (both Unibus and Qbus, including several CPU boards) and a couple of Rainbows; Several BBC model Bs (don't know what sorts) and an electron; Tatung Einstein, TI 99/4A; Sinclair ZX81, Spectrum, Spectrum +2; IBM PC-AT, 6150 (= RT PC tower model), System/23 (5332 Datamaster); A couple of Compaq 386 lapdogs; HP 71C, 75C, 85, 86, 87 (but the HP I use most is my 28C - I suppose that's a classic now); Sirius-1, FTS Series-88 (nearly two of those), Superbrain; I recently got a couple of Apple ][ and a couple of Exidy Sorcerors; But my favourite is the Tektronix 4052 graphics box. With luck, I'll bring it to the VCF this autumn ^H^H^H^H^H^H^H fall. Philip.

The B-plus was a model introduced after the B but before the Master Series. It had a lot of features of the Master 128, but was in a case just like a Model B. The circuit board is completely different, though. Different processor (65C12, IIRC), 64K RAM expandable to 128K, shadow memory and extra modes, etc, and a very different layout. -- Pete Peter Turnbull Dept. of Computer Science University of York

I didn't include terminals, such as my VT131, a couple of Cifer terminals, and some Wyse terminals. If the WP-2 runs software, even just a dedicated word processor, I'd probably count it. -- Pete Peter Turnbull Dept. of Computer Science University of York

I would probably go with a really fine sandpaper to give the paint something to stick to, then if I wanted, clear coat the finished product for a good seal against possible flaking. I painted a 14" SVGA monitor once. Flat black, straight out of a cheap spraypaint can. It never flaked, but some did rub off when I moved the monitor. I touched it up with black magic marker. I have this weird idea that one day custom paint jobs on computers might make me some extra money. Am I crazy? Do you think there would ever be a market for it? I've seen one guy on the net that has built custom mahogany and marble cases for his Mac cx and others.

QUESTION: Is there a way to determine just >how clean such a clean box is after its built? Is there some meter that >can be hooked-up to the exhaust opening that will give you a particulate Yes there is a device used to count particles in the air. But you may not like the cost of them. My job involves work in our Class 10,000 cleanroom at my place of employment. A few of you others out there either once had or now work in such a company that has cleanroom(s), or possibly had spent time in a cleanroom as a service person. I can give a brief primer on how a cleanroom is built and short definition of the federal standard of cleanroom classes if some of you are interested. That would give a picture of the environment within which the drives had been manufactured and what one would do to make a simple one for his/her use. We make linear encoders of which the finest line size of the ronchi ruling on the encoder substrate is 4 microns (157.48 millionths of an inch.) Figure one micron = 39.37 millionths of an inch (0.00003937"). Most dust particles in 'free air' (the air we normally live in and breathe everyday) are in the 0.5 to 10 micron range. Therefore, keeping the air _clean_ during the manufacturing process has benefited us extremely well. Of course, semiconductor manufacturers fabricate microprocessors, transistors, all other IC's in cleanroom environments. Those hokey Intel TV advertisements with cleanroom workers in full body suits are actually not far off the mark with regard to the actual need to keep a class 10 or 100 cleanroom clean when making chips with sub-micron features. I had purchased a particle counter at work to check the "cleanness" of the air in various zones in the cleanroom. These machines are somewhat complicated though the basic concept used for counting particles is not. Most particle counters are sensitive. The one I bought is able to "see", therefore count, a *single* particle as small as 0.5 micron. Our unit has similar specifications as other typical brands of particle counters but it still cost us a little over US$10,000. Used equipment dealers have them for less but it's still not reasonable for the hobbyist or even a very small business. Maintenace parts and calibration is also a bit high. BTW, the air quality in most areas of our cleanroom stays at less than 100 particles per cubic foot. Very clean when considering that outside air which is relatively clean (say, the proverbial fresh mountain air) has 100,000 to 500,000 particles per cu. foot -more with forest fires, etc. nearby. If I do decide to tinker with some of my dead hard drives, I plan to bring them to the plant some weekend and have at it :-) I'll just slip on a boufont (sp.?) cap as a hair cover, special gloves, my lab coat and maybe a face mask of some sort, setup at an empty table and away I go! >count? My Panasonic vacuum cleaner has such a detector that triggers a >dual-color LED on the front panel: it lights red if it detects dirt >particles passing through the hose and green if the particle count is >below some threshold. This is an extremely simplified version of a particle counter. I can envision it as having a simple LED emitter, probably IR, on one side of the hose and a photodetector on the opposite side. The detector and the analog front end may be rather sensitive to differentiate minute changes in light intensity. When significant amounts of dust and crap are sucked thru the hose the light is slightly occluded whichs lowers the output of the photodetector which then trips the circuit driving the red LED on your Panasonic vac. This is much too coarse of a device to measure air quality in any home-built glovebox/cleanroom any of us may build. It serves to show the homeowner that the Panasonic company's wonderful Model Such-and-Such is doing a great job at cleaning their house. Pure marketing gimmick but kinda neat on a home vac anyway IMO. > >> Yep, this is an interesting thread for me... > >Me too! Thanks for starting the discussion Sam, as a few of us who have the resources will need to get into it in the future -if not now. I can offer additional ideas and advice from my own cleanroom experience to the group on setting up a work area using either homemade or used commercial "clean benches", etc. Regards, Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA Member of Antique Wireless Association URL: http://www.ggw.org/freenet/a/awa/

hard drive data recovery

by dastar＠ncal.verio.com

This is off-topic, so I'd like to know if anyone would like to start a short discussion off the list regarding data recovery on crashed hard drives? I recently had two hard drives go south on me. One was my 2.5" IDE in my laptop...scary considering it had all my notes, memos and source code. The other was a 3.5" IDE on the voicemail system in the office. The laptop was a physical crash; the voicemail was a soft crash (directory got over-written somehow). I took the hard drives to a data recovery shop (Data Recovery Group in San Leandro for the locals). They have complete clean room and repair facilities. The data recovery technician, Yongin, opened up the 2.5" HD in the clean room and found the head had gone bad. He assembled a new head onto the drive but it wasn't repairable: it was a temporary fix to get the data off. He then proceeded to extract all the directories I told him were the most critical. Over all he said he was able to read about 60% of the 1.2GB drive. The other drive he found had a bad root directory, apparently having been over-written with random data (I suspect a virus). They basically used Norton Utilities on that to locate the lost directories and re-link them. They were able to recover the entire drive contents. What I wanted to discuss is the possibility of doing home drive repair without the luxury of a clean room. Is it possible to use some sort of cheaply available or easily made vacuum chamber with positive airflow and filtering, or is it absolutely required? Can a drive be opened in room air and be worked on without introducing dangerous dust particles onto the platter? Figuring out the data on the drive is the easy part, compared with actually trying to read the data off the platter, whether the problem be a failed head or a crashed head. Why can't they make a hard drive that's crash proof? Even if the mechanics fail, can't some hardend substance like glass be layed over the platter so if the head did crash it would only scratch the glass? Then you would simply open the drive, pull out the platter, replace the glass shield if necessary, then insert it into a working assembly. The head calibration would be adjusted to compensate for the extra distance to the platter. If anyone would like to continue this discussion, please reply to me privately. Thanks! BTW, the above drive repair cost $1,490 total. Not only is the job challenging and fun, but highly lucrative. Back that data up!
