But let me guess, if you are guilty of murder you likely lose any privacy rights attached to your SSN. That's why, in this case, it's out there for all the public to see. Just like they post the names, photos and addresses of sex offenders on websites. But I guess that's "totally inappropriate" too. "Totally inappropriate"? In my book murder is "totally inappropriate." Making public the SSN of a convicted murderer, even if done intentionally, just isn't. At least, as the target of your "totally inappropriate" attack, that's my current take on it. -W

RT-11 installation

The RX01 used the DX driver and the RX01 used the DY driver. If the driver on the floppy does not match the actual drive, it will not boot. So, a normal RX01 floppy will not boot in an RX02 drive and vice versa. However, I THINK that if you used the wrong density floppy but put the right driver on it (An RX01 floppy with the DY driver as the boot driver) it will work, but that is not how the distributions were set up. Of course there are games you can play, like toggling in a bootstrap, but I don't think that was being asked. Well, anyway, that is what I remember of it, please, anyone, correct me if I'm wrong.

Lots of people have names that are common with other people, and these databases are largely used by employers to do background checks on potential employees. Providing the SSN greatly reduces the risk of a false positive that could result if you only ran a search by name - in other words, if the SSN doesn't match, it isn't the same person. As some may recall, when Schwarzenegger was campaigning for governor in CA there was a woman who accused him of groping who was immediately identified by the Schwarzenegger campaign as having been previously convicted for prostitution. Turned out that the hooker was a different woman with the same name. All they needed were a couple of SSNs. -W

In NZ

by ethan.dicks＠gmail.com

OK, all... After 57 weeks... I have escaped the South Pole and am spending some wonderful warm sunny days in Christchurch, NZ. Should be here for a few weeks, so if any Kiwis on this list would like to have a get-together, let me know by e-mail, and I'll pass on my mobile number (which I'll be getting in an hour or so when I pick up a sim card for a borrowed phone). I have plans to visit the North Island later this month, but for a few weeks, I'll be here, hanging out. Cheers, -ethan P.S.- for another week or so, I'll have my Elf and SBC-6120 with me before I consider mailing them home... if you want to see one... there's a brief window of opportunity. I have a week left of U.S. postal priveleges with the program.

I usually put them on a hefty 5V supply and feel for what's hot (you can sometimes burn out the short in a decoupling cap that way -- they often go bang). Point of reference: a BBC B board normally draws about 2A at 5V, but the last one I had with a particularly nasty set of faults drew over 10A at 5V -- and the faulty TTL chips got hot enough to feel without actually touching them. > Given a suitably sensitive meter is it sensible to assume I can try and > home in on the short location a little?

Finding shorts in boards

by melamy＠earthlink.net

the biggest culprit when it comes to older electronics is the good old tantalum cap.

I use a current limiting supply and set it to about an amp or two. I place the supply across one of the power planes ( corner to corner on a solid plane and end to end for E traces ). I do not place the supply form power to ground, just across the one plane. I then place one lead, of a meter that reads 5 digits on a 200 mV scale, from the opposite rail that is shorted two. One then simply traces for a null on the plane with the current flow across it. On a plane, I take a piece of string to mark the line of the null and then put the supply on 90 degrees, across the same plane. Where the new null line cross the old string is the where the short is. This method will even work if the short is +1K, if that is the only current flow. I once showed using it on a burnin board with a 10K resistor that was in wrong out of some 400 sockets and about 12 resistors per socket. I was able to zero right into the exact resistor. The principle is that one uses the plane as though it were a variable resistor and the short was the contact. If one measures along the resistor to the contact, the voltage will be zero at the location where the contact is made. This is much easier to read than CRC's method since you are looking for a null, rather than a stop in the change of the voltage. It also has the advantage that it won't blow an intermittent short so you can find it. It is more sensitive than the HP current probe for power planes ( having used both methods ). It also is run at a very low voltage so there is no chance of damaging other parts. I publish this method every now and then but most people don't think about how it works and will tend to forget it. Such is! Dwight

An ohmmeter will not normally cause the silicon to conduct and hence be counted in the total resistance. Some chips do have internal dividers, but the they are nomally in the 10K + range. I normally use a current limited supply at the required voltage and set the limit so that it starts to limit. I then use a 5 digit voltmeter to trace where the current is going. This is done by placing one probe on the +5V input and then measuring the drop as you trace out the distribution path. The path drawing the current will continually drop while non-drawing paths will remain at a constant voltage drop. On multi-layer boards you measure drops to the Vcc pins of the bugs and map the drop. CRC

Finding shorts in boards

by julesrichardsonuk＠yahoo.co.uk

I've got a board here with a short between ground and the +5V rail (actually not quite dead - I'm getting around 10 ohms between the rails) Any useful tips for finding the fault? It's a large board, multi-layer, lots of silicon on it unfortunately :-( Are there any particular components that are likely to fail in this way that might be found across PSU rails? (decoupling caps, certain ICs, crystal modules etc.?) Given a suitably sensitive meter is it sensible to assume I can try and home in on the short location a little? (I've found readings between GND/supply on various LS chips of anything between 9.5 and 12 ohms so far) I've checked the board for particles of anything that might be causing the problem, plus I'm halfway through ruling out any of the socketed ICs. Of course if it's a problem with the multi-layer PCB itself... eek! (do these ever fail in such a way though? It's a commercial board which used to be fine) cheers Jules

A couple of freebies...

by auringer＠tds.net

While cleaning the past weekend, I came across a couple of things that I thought I would try to find a home for. 1) Manual for a Aydin Controls "Slow Scan Analog Patriot Series High Resolution Color Monitor", March 1985. I also happen to have a model 8831 monitor, which is covered in the manual. I do not know the working condition of the monitor, but the cosmetic condition is O.K. The manual contains schematics and troubleshooting information, so I would think making the tube work should be possible. The tube is big, and needs to be picked up on the east side of Madison, WI. 2) 1985 Sharper Image catalog. The only thing I thought was interesting was the ad for an Omnibot 2000 robot. Anyone interested for the cost of shipping? Jon
