They restricted the use of HEAT SENSORS but they did not restrict the police from using estimates of exceesive power usage by the power companies. That's how they "caught" Zane. The thermal imaging sensors would have probably shown that the source was a computer and not growing plants. BTW they also use both technologies for detecking stills built inside of homes. Joe

More Amiga finds and a some great articles to read

by jrkeys＠concentric.net

Today I was able to find the keyboard and monitor for the 2000HD I got yesterday. Stopped at Borders Book store and found the January 2003 Nuts & Volts has a good article on the Altair 880 titled MICRO MEMORIES. Maloney's Antiques & Collectibles Resource Directory list Computers as a collectable and points several people we all know as experts and recommends books and sites to check out. Also while there looked in Warman's Flea Market Price Guide 2nd Edition (2001) it also list computers as something to look for but boy the prices they give way out of range. Here's are some: a Mac 128 $350, a Mac Plus $50, a IIc $65, a Atari XL800 $125, and a Epson HX-40 $125. Check it out for the remaining ones.

PDP-8: (and others) anyone tried NVRAM simulation of hard drives?

by djg＠drs-esg.com

From: Ethan Dicks <erd_6502(a)yahoo.com> > >As to Will's original question, I myself have wondered what it >would take to design/build a compatible device. ... >One thing that has been slowing me down is >deciding how to attach a modern device to an -8/L or -8/i - > I would recommend getting the DEC compatable cards for Dougless Electronics to plug into the 8/I and wiring them to another circuit card. With a bank of transistors you can convert from the negative bus to TTL and put a small FPGA/CPLD on the board to do all the work. Attach to that your storage of choice and your all set. A fast microcontroller might also be an option and might be needed if you want to do things like IDE/CF to emulate DF32/RF08. Might need to be a little careful that modern fast logic doesn't see/make glitches on the bus. For my online PDP-8/E the board I made is a Xilinx CPLD (they have cheap/free tools and I have the pay stuff at work) which emulated the front panel and also was a single cycle data break master for data transfers. Most of the 8/I peripherals were 3 cycle that wouldn't be too hard to do. I used a little adapter board to convert the PLCC to a PGA and then wirewrapped. I have also seen a bunch of ads for real cheap PCB prototypes if you have confidence in your design. Anybody who wants my code can have it but it is ugly. I first tried another chip and coded it in that language but the tools were too bad so switched to Xilinx and Abel. David Gesswein http://www.pdp8.net/ -- Run an old computer with blinkenlights.

MicroVAX 3800 Power Cable

Is there another standard that covers the 20A variant? There isn't a 20A variant here :-) In Europe (where the standard comes from!), there are two versions. As I recall: The first you commonly see on electronic equipment, which was originally rated for 6A (IIRC) and later I think up to 10A or 12A (*providing* the cable is also suitable for that current). There are "hot condition" and "cold condition" variants, the "hot condition" being the one for appliances like kettles, platewarmers, etc, which get hot (or warm, at least) and which has a notch in it, to prevent a normal "cold condition" plug being used in error. Although you rarely see hot-condition plugs rated less than 10A or so, that's because you need a 10A rating or more for a kettle element, not because the hot-condition plugs are designed for high current and cold-condition ones for low current (as some people mistakenly think). Eric (Smith) is correct, the difference with the notch is purely temperature rating; maximum current rating catered for by the standard is the same in each case. Be aware, however, that while there are few 6A hot-condition cables, there are quite a lot of 5A/6A cold-conditon ones; indeed they're the most common here, being supplied with every Sun, PC, monitor, network switch, and many domestic electronic devices. Don't chop a lump out of the edge of one of those and expect it to handle 10A safely. Look at the printing on the socket first. The second version is a little larger, has the pins at right angles to the pins in the 10A version, and is rated 16A. In the USA, both versions are allowed higher current ratings, so what you call a 20A version is what we rate for 16A here. This is a result of the USA using an inferior voltage standard, requiring higher currents and leading to greater losses :-) -- Pete Peter Turnbull Network Manager University of York

[OT] Update on White LEDz...

by zmerch＠30below.com

Classiccmp Dudez/Dudettez... Just wanted to say thankz on the help y'all gave me WRT the white LEDz question I posed earlier... Lotsa info I need to sort out in the old, tired head of mine... ... but for anyone else who's interested in stuff like that, thru further googling I stumbled across this site: http://www.candlepowerforums.com/cgi-bin/ultimatebb.cgi A forum all about -- you guessed it! -- different lighting techniques including white LEDz... Anywho, thanks for all the help, and as things progress...

Annex 3 terminal server

by toby＠russellsharpe.com

Hi, I've got an old Annex 3 terminal server which I'd like to connect to my PDP-11 so I can have telnet access into it. Trouble is, I don't have any software with the Annex and I can't work out how to configure the beast. Anyone have any experience with them or suggestions as to how I can get hold of the configuration software? Thanks, Toby
