I thought my wife killed one of my cats with one once. The cat was so in need of catching the little red dot that it didn't realize it was exhausted, until it just fell over panting and stayed on its side for the next 20 minutes trying to catch its breath. Ever since then, we limit the laser pointer time to 5 minutes at a shot. -chris <http://www.mythtech.net>

vintage 3.5" disk drives

by PLancashire＠columbia.com

I use to have before the fire, a box full of about 50 different 3 1/2's My eon's ago i was responsible for evaluating 3 1/2's for Tektronix. Three different types, and you should have seen all the rev's Sony went through. The part I remember the most is the convincing the now loosing camps use to try to put down the Sony design. I'll see if I still have some of the doc's and such, if i do, I'll put them on a web site. -pete -----Original Message----- From: Curt vendel [mailto:curt@atarimuseum.com] Sent: Monday, October 27, 2003 7:32 AM To: General Discussion: On-Topic and Off-Topic Posts Subject: vintage 3.5" disk drives Did Seagate and/or Shugart get into making 3.5" floppy disk drives around 83/84???

Any suggestions for cleaning yellowed computer parts?

It does dissolve the surface of most plastics. After about 5 - 10 seconds of application I use ethyl alcohol to stop the reaction (Wipe with another saturated cloth). Seems to neutralize the Goof Off. You have to be quick. Doesn't work on clear plastic. Paxton Astoria, OR

The Geek Test...

by blstuart＠bellsouth.net

> How many of you have seen this one? > http://www.innergeek.us/geek.html > I only got a 7.88955% result... 52.66272% - Super Geek The thing that troubles me the most is that I think I'm more annoyed by the fact that there weren't more deeply technical questions so that I could score higher than by the fact that I scored high enough to be labeled a "Super Geek." Boy, it must be getting late. That sounded too much like Super Freak. Now I'll have that song stuck in my head for the rest of the night... Brian L. Stuart

Cats

by CordaAJ＠NSWC.NAVY.MIL

Actually, I remember reading somewhere that cats have limited color perception. To a cat, red appears to be black. Don't know what green maps to, however... -al- -acorda(a)1bigred.com -----Original Message----- From: Eric Smith [mailto:eric@brouhaha.com] Sent: Tuesday, November 04, 2003 2:51 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Cats ben franchuk wrote: > Still the best cat toy is laser light pointer, they all love to go > after that spot of light. Sellam Ismail wrote: > I've have had an incredible amount of fun with a laser pointer and a cat. Note that doing this for the purpose of exercising the cat may violate US patent 5443036. The patent makes no claims about doing it to entertain the human and/or the cat, however. The patent may be invalid anyhow, as it describes using a "beam of invisible light", which surely won't hold the cat's interest. A beam of red light works much better. I haven't tried a beam of green light, but green laser pointer prices have come down enough that it is tempting to try it the next time I'm in Colorado. (None of my close friends here in California have cats.) Eric

Non crap plastic glue

by cb＠mythtech.net

>> I've got a plastic push gear I'm trying to glue back together, and so far > >Ah... What's it out of? Any chance in getting, or making, a replacement gear? Its actually for a VCR, and an off topic one I might add (its only a few years old). Yes I can probably get a new gear from the manufacturer, but they are a royal PITA when it comes to getting parts unless you have a specific part number. Of course, they don't stamp their parts with the numbers, nor do they offer exploded diagrams that list the part numbers... which leaves one in the nice situation of not being able to order the part because you don't know what they refer to it as! I've had to jump thru serious hoops to get parts from this company in the past, and I figured that glue would be easier then trying to get the replacement part. As it stands, from the sounds of it, glue isn't going to be any easier, so most likely, the whole VCR is going to be disposed of rather than spend any more time on it. (Its for a local animal shelter I support, its a crappy TV/VCR unit that the cats use to watch videos of birds... I'm not willing to spend any more time working on it when I have a VCR and TV I can donate to them instead, and since they are two different units, I can wire up the TV in the cat room, and the VCR in an office down the hall, which will greatly reduce the amount of cat hair and litter dust that gets in the VCR, which was the cause of the failure in the first place. What I REALLY want is to hook them up with a computer running MPEGs of their videos... that should drop the wear and tear factor down to almost nothing as the computer doesn't care if the hard drive spins 24x7 for the next 20 years) However, I'm glad I asked about glues, as this VCR is just what drove me to the point of trying to find a decent glue. I've run into the problem on a number of things in the past, so now I'm a bit more educated in the topic for the next time. -chris <http://www.mythtech.net>

Cats

by CordaAJ＠NSWC.NAVY.MIL

Ok, did a little web search on this, and found... http://videoforcats.com/catvision.htm Don't know how authoritative this is, but it sounds like they did a bit of research... It would be interesting to see how a cat would respond to a green laser pointer... apparently green is one of the colors they seem to be sensitive to. BTW, this is getting off topic... perhaps it should end soon. (with apologies for drawing it out)... -al- -acorda(a)1bigred.com -----Original Message----- From: Eric Smith [mailto:eric@brouhaha.com] Sent: Tuesday, November 04, 2003 4:37 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: RE: Cats "Corda Albert J DLVA" <CordaAJ(a)NSWC.NAVY.MIL> wrote: > Actually, I remember reading somewhere that cats have limited > color perception. True, AFAIK. > To a cat, red appears to be black. Not true. Otherwise they wouldn't be interested in red laser pointers.

AVL road Runner computer

by Innfogra＠aol.com

Joe; I recently sold one of these on eBay, not for much. The Roadrunner is a multi event controller for multiple slide projectors. The monitor plugs into the video connector and is just a composite monitor for the computer. I think the 5" monitor power plug fits into a matching socket on the expansion box so that is the one I would use. the disk drive plugs into the back of the expansion cab. Plugged together something should come up on the screen. IIRC the Record Out and Play In are for the control signal pulses generated by the controller. Also Out 2 on the expansion unit. The patch panel looks like it is for audio. The most interesting for me would be the S100 Eagle. AVL did use S100 computer systems. The 9" monitor and the keyboard go to the Eagle box, as does one of the disk drives I think. The Roadrunner I sold was just the small controller keyboard. And it was missing a keycap; I got about $28 IIRC. The Eagle is late 1970s or early 80s and the Roadrunner is early 1980s. Video projectors have taken over most of the market for this for multiple slide projector shows. You seem to have complete sets of equipment so it is probably worth getting the Eagle and saving both.

13W3 question / SGI Indy lost root passwd question

Or are there > better means? (Anyone want to sell me a cheap copy of IRIX ;-)) if you can gain access to the root account there are tools to make copies of the disk. or else you can do a copy of the disk by installing a second disk. ebay should have plenty of small 50 pin scsi disks that can be used for this for a few dollars. the disk can be copied in the bios.. just look up disk replication and there are documents on how to do this. > > TIA, > Owen Marshall > Linux Geekboy, SGI > Fanboy
