Heya, Does SGI have a timeline or anything up anywhere. I am wondering what the first SGI workstation was(R2000 right?). I know they made terminals before that, But i am just wondering about workstations. Thanks, Torquil MacCorkle III Lexington, Virginia

EPROMs don't have UV-opaque glass windows, they have UV-transparent quartz windows. So they can be erased, but not by casual exposure. Regards, -dq

[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

It also said that my message was rejected but it >wasn't. I sent Jay a note about it already. OK... Now I see what's happening. I received a rejected notice earlier because I have opted out of the CCTALK list. My posts will appear in CCTECH but, not in CCTALK and I'll get a rejected notice from CCTALK for each post. I can live with that. It's certainly better than all the noise I was getting previously. To keep the message on topic: I am still undecided about the Junk fest tomorrow in Orlando. I have a potential scheduling conflict and might have to pass..

[CCTALK] EPROM Life... Was: scanners & circuit boards...

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
