Those must be newer pinball games. That open one I saw was probably 1950s era. I suppose they now have more computer circuits. Since you mentioned CMOS RAM, I see that is true. Now I learned something new :) >of them - I assumed safely, but not so sure now that I hear about all >the recycling done in 3rd world countries... >John :-#(# Yea, I know what you mean about the 3rd world recycling. Once again, the government is showing their stupidity. In my area, Goodwill stores can no longer sell computers or computer parts. I run older computers with PS2 mice and keyboards. I also prefer the old ball mice. My mouse died and I went to Goodwill to buy a new *used* mouse. I was told they are not allowed to sell any computer stuff anymore. It all must go to the state's computer recycling program. I said "but you should still be able to sell a mouse or keyboard". I was told they have no way to test them. (As if it's difficult to plug them into an old computer and see if they work. (Plus half the other electrical stuff they sell is broken anyhow). It would seem to me that the best way to recycle things like that is to sell then to people who can reuse them, but when it comes to the govt. nothing they do makes much sense. (I found a seller on ebay who was selling the old PS2 ball mice NOS for $5.50. I bought one and it was identical to my old one that died, so I bought a couple more. That's the kind of mouse I like, and I can use them on a newer computer too, with a PS2 to USB adaptor (which I also have). |

I beg to differ. I have had NiCd and NiMH cells leak. The difference is that unlike alkaline, they don't leak in the package: <http://www.learnbydestroying.com/jeffl/crud/Kirkland-AAA-leak.jpg> I've found from dealing with commercial walkie-talkie batteries, that if I leave the packs totally discharged for more than a few weeks, the batteries will leak. The good news is that this rarely happens. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
KenO <kenitholson@yahoo.com>: Feb 20 08:12AM -0800 tabb, "Simple really. Alkaline batteries leave what looks like white fuzzy crystals. Some times with bluish green tint." Blue and bluish green is what I have. Have made 2 jpegs of the contacts and since have not received any tips how to attach in this forum Googled and found "HOW TO SHARE FILES WITH GOOGLE GROUPS by James T. Cains" http://www.dummies.com/education/internet-basics/how-to-share-files-with-google-groups/ "...click Reply. Click Attach a File." Somehow attach a file does not show in my Opera Browser or doesn't this forum allow attachments? |
FreeMan <freeMan@SpamFree.com>: Feb 20 06:53AM -0800 Electronics are OK but the fan is super noisy on both my units. Took it to the local Oreck dealer and they said no can fix. These have the buttons on the top and have a silver removable cover to access the filter. But can it be fixed ? Bearings available ? Amazon has new but it will not let me make a purchase based on my location (Southern California). Why ? I have used the two I have for over 10 years but now cannot stand the noise. |
Terry Schwartz <tschw10117@aol.com>: Feb 20 06:58AM -0800 10 years is a significant run time for a fan motor. You could try lubricating the bearings but it may only provide temporary abatement of the noise, if any. It's unlikely that bearings are replaceable, and even less likely that you'd be able to find them. You might have better luck trying to replace the entire fan.

This site seems to have at least some of the models shown in exploded view. https://www.ereplacementparts.com/oreck-air-purifier-parts-c-130239_130321.html |
