Howdy!
Catalogs have been finally updated, and cleaned up! Now dowloadable as
simple text files. Also some errant phone numbers (Thank the printer of
the document I had to work with!) have been fixed. Sorry for any

I have made a simm72 socket connector. Could anyone check if it's "ok" ?

Does anyone know of a (preferably) standalone 2.5D (or 3D) field solver that
can read in a Gerber data file, be provided with stack-up data (dielectric
constants, loss tangents, etc.), and then let you willy-nilly define ports to
look at S parameters (or similar)?  The primary ...

I work for a small company Goldenrod Research Corp. which manufacturers
computer interfaced robotic arms and technology education equipment for
sale to elementary schools.
In the intervening years since we last reordered our printed circuit

Good morning,
Sorry for my little english ,
I'm a italian technician ,
I search the service manual of an old oscilloscope Philips PM3217.

Does anyone know if exist a library for protel of panasonic electrolytic SMD
capacitor FC or FK series?
i mean, they're the typical SMD capacitors but i can't find the footprint
over all libraries.

I was wondering if anyone here has ever designed and produced a working PCB
with Kicad, the free open-source CAE package. I've looked around but haven't
found anything.

Anyone had any success in using this program? Every time I enter any
parameters (even for the most basic bandpass Butterworth, for example)
the thing just seems to complain and won't come up with any valid
result. :-|

Can anyone recommend a really good course on PCB layout, preferably
generic rather than tool specific.
I've manually routed several high speed boards with ORCAD, some even
with mico-vias but I'd like to get into consultancy and a bit of paper

I have been hearing a lot about Klik for Linux and see that
most of the gEDA tools are in the repository.  Doesn't look
like the gEDA team maintains it though.  Will this change,
or is it not a problem?

I route single sided board and I cannot use jumpers? When I'am trying
to put a jumper on  track a message appears "Can't add jumper". When
I'am trying to put a jumper while routing nothing is happend, my comand
(Ctrl + Alt + J) is quite ignored?? What is wrong??

I work a simple single sided board in PADS. I have my components placed
on board and all rules are set. Some of the tracks are routed ok. But a
little rectangle (rhomb in fact) appers at the corners of some routed
nets!!!

Somebody on this ng was kind enough to port me an old dos copy of EZPC
inside of two files named disk1.zip and disk2.zip.  I copied all the files
from disk1.zip to a floppy and similarly from disk2.zip.  I booted with an
old dos 6.22 disk and tried every trick I knew to install ...

I'm trying to use a PSpice model from International Rectifier on Protel 99
se. Protel use XSpice to simulate circuits.
The model can be found here :
