We have had lots of fun pitching stuff into a 30 yard dumpster when we had one delivered. The first time we were in a seven story warehouse with stuff on the 7th and 4th floors. A stereo system dropped from the seventh floor can literally jump out of the dumpster upon impact. This was the first we tried. Containment works better when there is a little debris in the bottom. The first few items jumped right out of the dumpster, bouncing off the metal bottom. Of course they shatter when hitting the bottom making a mess to clean up when they jumped into the street. We did this on a Sunday morning, I recommend checking when your local authorities are not available. It makes a lot of noise and can attract attention. In NW Portland Oregon no one came by. After cleaning the street up of the first items we moved to the 4th floor where we had 60 Wang Terminal tubes to dispose of. These did not jump out of the dumpster. The fall from the 4th floor was not as great. They made a great pop when they hit the dumpster. It was a noisy morning. The Wang 2200 tubes were over 10 years old so it fits the criteria of the list, not to mention this was also in 1989, more than 10 years ago. It was before we realized the potential toxic hazard we were unleashing. Another time we had to despool several pallets of spooled wire. We took them up to the roof and dropped the spools into the neighboring parking lot. If you dropped them just right the spool would come apart and the coil of wire would rise up about 6 or 8 feet off the ground. Did not damage the parking lot. Lots of fun for work. A heavy aluminum or steel chassis will make marks in both concrete or asphalt. Plastic shatters making a big mess. We preferred to restrain ourselves until we had a dumpster to toss things into. Properly contained it can be a lot of fun. Paxton Astoria, OR

But regardless, scanning would be causal exposure, and such exposure (even if that glass were UV transparent) would be unlikely to be able to hurt the EPROM. But the only boards with EPROMs I've ever seen that *didn't* have labels covering the windows were ones I did myself or ones where the label glue had dried up and the label fell off.

[CCTALK] Re: Keycap cleaning strategy

by fmc＠reanimators.org

I do this sort of thing for Northgate Omnikey keyboards. Two paper towels, folded on the perf, to the left of the sink. One margarine dish in the sink. Fill margarine dish with hot water. Add a little dishwashing goop (I use Palmolive because it's there). Pull some key caps from the keyboard. Put the caps in the margarine dish and swirl them around. Let them soak, while you pull the next batch of key caps. Remove and scrub with a sponge one cap at a time, shaking the cap to remove any excess water before sitting it face down on the paper towels to dry. Repeat 'til done. You'll probably need to move the paper towels (before they get too covered with caps) and fold another set, maybe twice or three times to get through the keyboard. Be careful when pulling big caps, they usually have some supporting widgetry that can go flying when the cap pops off. While the caps are drying, you should take the keyboard the rest of the way apart to blow out any dust and detritus and scrub the casework (again, dishwashing goop and water, maybe stronger stuff if needed). Let it all dry before putting it back together. Once cleaned, I generally wrap a keyboard up in a 13 gallon kitchen garbage bag to keep it mostly free of dust and critters. Cables can be coiled up inside the bag too. (Yes, I have a supply of spares... I use these keyboards!) -Frank McConnell

Over time, >I have seen some of the coating flake off the inside of old >flourescent tubes, providing a bunch of small UV "windows". The fluorescent tubes used in offices usually have ordinary glass and in plastic fixtures. I would suspect that the 3 year period is rather pessimistic. Many scanners use halogen lamps. These produce quite a bit of UV. Infact, a bare halogen lamp can be used to erase EPROMs with a fan for cooling. It won't be fast but it will erase. The glass plate in a scanner still blocks much of the UV light that would cause damage. I wouldn't think that running it through a scanner would remove more than about a months worth of normal aging at most. Covering them is simple and makes good sense. Still, it is a good idea to store good data from EPROM's in a different form. I always make both a *.BIN file and a printout of any of the EPROM's and most of the ROM's that are in my older equipment. Cosmic rays will eventually erase any EPROM is leakage doesn't do it first. I have some 1702A's that were programmed over 20 years ago that are working fine ( around 1972, almost 30 years ). On a side note, ceramic packaged parts will also scratch glass. Dwight

Hi Jewelers rouge will remove scratches from glass. It does depend on the depth. The reason I know this is because I am also an amateur telescope maker and rouge is a common material used to polish glass. If the scratch is deep, you'll need to grind with something like 15 or 5 micron aluminum oxide. You'll note that both rouge and aluminum oxide are both oxides of common metals. These are harder than glass and can scratch glass under the right condition. Also, carbon steel wheels are used to scribe glass ( but this isn't scratching, it is fracturing so this doesn't count but the results look the same ). Contact me off group and I can help with your CRT problem. Dwight

I'd be more concerned with accidentally scratching the glass bed of the scanner due to sharp component leads. You can't scratch glass with metal. What you can do is leave a thin trace of metal on the glass. Gewelers rouge will easily remove this is nothing else will. I guess that there is a slight possibility of degrading the contents of an EPROM if its window isn'tcovered. Glass is opaque to UV so you won't erase EPROMs either.

Try running your windshield wipers without the rubber. Although, it may be true that glass has a hardness greater than most metals, this doesn't mean it won't get scratched. The problem is that it also fractures easily ( sometimes at a microscopic level ). The tiny chips embed in the metal surface and that scratches the glass. This is a multiplying effect. Also, most oxides of metal are harder than glass. And lastly, the quartz windows of the EPROMs are harder than glass. >>> >>> I guess that there is a slight possibility of degrading the >>> contents of an EPROM if its window isn'tcovered. >> >> Glass is opaque to UV so you won't erase EPROMs either. > >EPROMs don't have UV-opaque glass windows, they have >UV-transparent quartz windows.
