Painting Macs (was: fake NeXT)

by poesie＠geocities.com

My girlfriend works for a sign company that does small and large scale signage; including printing out vinyl signs. they can print onto lexan, transparent vinyl, aluminum, etc etc; our project last week was making a tower case out of clear acrylic, and putting some various translucent designs on it (including a very dashing "Linux Powered" logo.) the company is www.fastsigns.com, there are local all over the US and i believe also england. for a full colour case design (they can scan and print any graphic) it's usually about $50 US and then the cost of the materials. most likely under $100. i'll upload some shots of this awesome case once i get my digital camera back from a friend. -Eric >Absolutely! :-) > >I'd certainly be interested in a Mac with a neat paint job.

No, they used "ROM Pac"s, which consist of a small circuit board with a decoder chip and 4 x 2KB ROMs mounted inside a gutted 8-track tape cartridge. -- Pete Peter Turnbull Dept. of Computer Science University of York

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 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!
