The problem now is that it is the 14 pin chip. I'm not sure what size

wire I should be using, but I have tons of 18 and 20 gauge, which are

obviously too large. Not to mention my lately unsteady hands.



(If small wire is not sold at Radio Shack I have a problem).



On the forum where it is discussed, the best idea seemed to be to connect

the Gnd wire to the VGA screw, and then to solder needles to the other two

wires from the interface and use them as probes to the IC until the program

has finished. (assistant needed to press 'Enter' etc.,)

I didn't see what pics you were referring to, but the instructions on how to do this assume that you know what is and how to use a command prompt, so I have to figure that out and following these instructions:

--------------------------------------------------------------------------------
"Fire up a command promt(Start-run type cmd) and navigate to the folder where you installed R24RF08 v2.0b. Type in (don’t hit Enter):
r24rf08 dump.bin"
--------------------------------------------------------------------------------

What doesn't make sense is #4 of the following instructions:

--------------------------------------------------------------------------------
1) Turn on your ThinkPad with all the wiring you just soldered.
2) Press F1 during the startup to enter the BIOS.
3) Wait untill all activity stops, blinking HDD leds and such.
4) Connect the ATMEL Chip reader. GND first then the SDA and SCL.
5) Now go to your spare PC and Hit enter on the command prompt.
--------------------------------------------------------------------------------

If everthing is already connected to the serial port, which is connected to your spare pc, then what is #4 for?

(I'm certain I'll hit another roadblock after this).

Thanks.

This step on the one PC (capturing PC), prepares a command, but
doesn't start executing or anything. It would not start executing,
until you hit Enter. You've been asked, *not* to press Enter yet.

Type in (don’t hit Enter): r24rf08 dump.bin

That is the program which is going to record some serial information
into dump.bin.

(I can see a reference to 24RF08 here, a part I'm not familiar with...

http://www.thinkwiki.org/wiki/AT24RF08 )

The other instructions 1) to 5), prepare the target machine. Connecting
the ATMEL Chip reader, now your target SDA (data) and SDL (clock) are
connected to something.

Going back to the recording machine, where the "r24rf08 dump.bin"
is sitting in the command prompt, you haven't hit "Enter" yet.
When you hit Enter, the program you're about to run, assumes the
ATMEL Chip reader is already connected, and it's going to run SDA and SCL
until some device is dumped. Apparently "r24rf08 dump.bin" collects
data immediately, which is why you don't hit Enter until everything
is wired up (and the target machine is in a known state, quiet in
the BIOS).

'Interface' plugged into the (Service) PC.

Ok, after some research I found that all I have to do is put "cmd" in "Run" and a command prompt box pops up.

I'll ust (try to) make up the harness and then plug it into the spare pc *after* boot-up.

(Back to the harness).

I spent hours trying to solder the leads to that chip. (And I have relatively steady hands).

I'll now have to get some solder off that is bridging a couple of the legs, and then try again. Though I may have already toasted the chip because the iron brushed over it a couple times. (That needle idea just doesn't work).

And now after seeing those pic links you posted I realized that I've been attempting to solder the leads to the incorrect legs anyway. (sigh).

Thanks.

Get an extra set of 4 tips for free shipping (got the soldersucker,
shrinkwrap, flux, tip rejuvinator paste, solder, 3rd-hands, etc. -
best prices from Singapore).

I've done minature 9- and 6- pin toggle switches and the tip's
adaptable and controllable - reasonably, there's no actual temp sensor
in the tip for something a quarter the price of a variable temp
soldering station. Very fine and close to whatever you're doing, I'd
imagine - I had to use magnifiers and lights to see the connects. It's
the very fine tip I mostly use among 4 provided.

I've $6 irons for beaters and up to a plumber's grade iron for big
stuff.

Evidently causes the unit to short and burns it out.

Took apart my wand and don't see the wiring issues, so hard to
describle what the fix is. Works great, as also follows many other
reviews.

Anyway, it required a two special screws to get the wand apart.
Luckily I had the right screw tip in a $3 Chinese cellphone
