Does anybody have a Visual 1050 with hard drive setup? I am looking for any doc/pointers on how to get a hard drive configured under CP/M for this system. Thanks.

They are probably perfectly good for photometric applications too, where it doesn't matter if it takes some time for the cell to adjust to the illumination. And as far as environmental issues are concerned, it would certainly be much better to get rid of CFLs. There has actually been some coverage in the news here about CFLs being thrown in glass recycling containers instead of being handed in as toxic waste (there are reasonably easily accessible places that accept toxic waste everyhere here as well, but nowhere near as many or as accessible as glass recycling containers) and causing problems at the recycling plants. LED lighting is being promoted instead. So far, there has been no discussion about environmental issues with semiconductor manufacturing... /Jonas

I'm not a UNIX expert so I must have misunderstood; you mean UNIX cares about file extensions after all and I can't name a UNIX executable "your_win.jpg" ? At least the modern DOS equivalent (which is what we're talking about, remember?) *does* show the all-important .EXE in the file name, as will Windows if you've enabled it.

I think you'll find dozens of references, as well as to your quote, e.g. http://inagist.com/CodeWisdom/146592721312817153/ or http://quotes.prolix.nu/Technology/Computers/ > PS: > Sorry for my broken english, never learned it in a shool or so, it's > entirely from using unixoid OS's and communicateing with people like you > over the net. > Proably it's still better as your german :-) I doubt it; born and raised in Hamburg my German's actually pretty good. m

The US big 3 automakers to their credit did a pretty good job with this for a long time. Yeah, cars in crashes still had good parts to pick over in a junkyard, but by the end of a cars natural life there really wasn't an awful lot left to pick over. Not that I'd wish a 1974 Dodge Monaco on just anyone :-) Tim.

I just saw your message about CMC which was the company I founded in 1968. I had no idea people other than I ever thought about it anymore. I can help with information with anyone who is interested.

But they didn't know of a 4th part; the corrosion inhibitor. Without the 4th part the caps were supposed to little time bombs, slowly eating away at their aluminum cases. I do know I woke up one night after having a dream of popcorn popping only to find a ATX p/s with caps going off like popcorn in the room next door. I unplugged the PC and put it in the bath tub and went back to sleep. Changed out the p/s the next day and it worked fine. ________________________________

I beleive that all CdS LDRs > are not RoHS compliant ;-(. This doesn;'t affect home constructios (at > least not in the UK), it does matter if you're going to use them commerially. CdS cells have quite a few problems that have made them obsolete for photographic purposes: temperature dependence, slow response and memory effect. They need a significant time to adjust to a different level of illumination to give a normal response. The response becoming non-linear with age has also been reported. For a long time cameras have been using silicon photodiodes instead. As an example of the memory effect, the manual for a Durst darkroom exposure meter, which I have just been given and which uses a CdS cell, says to illuminate the CdS cell immediately beneath the lens of the enlarger for 15-20 seconds before making a measurement. They do work well all the same, most of my cameras that actually have an exposure meter use CdS cells. And they seem to be easily available. /Jonas
