Currently, I am looking for some neural network chips for a particular
application . I don't require a large number of inputs (a maximum of 10 input
and 10 outputs ). I  have considered the Intel 80170NX but it's a bit too fancy
for my requirements. Could anyone recommend something please?

I'm considering the purchase of a 486DX2 66MHz PC.  The seller (Gateway 2000)
advertises that these systems are capable of being configured with a 
maximum of 64MBytes of main DRAM memory.  Investigation has shown that
their motherboards have four SIMM slots.  Currently, Gateway does not offer
the 16MByte SIMMs.  In fact, their sales rep sez that they only have the
4MByte SIMMs so if I *did* purchase from them, I could currently only
get a maximum of 16MBytes (four slots X 4MByte SIMM) total configured
at this time.

The sales rep also sez that Gateway currently has no plans to announce
*when* they may be offering the 16MByte SIMM arrays.  This raises a couple
questions in my mind:

1.  How ethical is it to advertise that a CPU being offered can be 
configured to 64Mbytes when in fact the vendor cannot provide this 
option?  It wouldn't be so bad if it was just a matter of a *date*, that
could be provided to me by the vendor.  ie... If they told me that on
Nov 1, 1992 we will be able to sell you the 16MByte arrays...

They cannot even tell me if I will have to 'eat' the 4MByte SIMMs once
they do (if ever) provide the higher capacity memory.  I would like to
think that I could get full credit of the 4MB SIMMs on an upgrade purchase
of equal capacity 16MByte SIMMs.  Gateway is not alone in this misleading
advertising practice.

2.  I have turned and read *every* page in this months issue of 
_Computer Shopper_.  I only saw one advertisement for 16MByte SIMMs.  Is
this beast so very new to the PC world that they are not yet available?
I'm trying to determine if it would be possible to purchase the 16MB
SIMMs from a 3rd party source and just install them myself.  If yes,
what else to I have to consider?  Are there others things that I am
missing? (like the ability to address the higher areas of memory)

Does anyone know more about this?  Please share it with the rest of us.
On a related note, the single ad it saw was for 80nS 16MByte SIMM.  Does
a faster SIMM exist in the 16MBytes capacity?  The 4MByte arrays that
are currently being offered are of the 70nS variety.

You can reply to me directly or post and share the knowledge with others.
Thanks in advance.

Since the green color and the sync are not active at the same time, did you 
try to OR them together via resistors? It may work.

I sympathize. I've tried doing up small boards with it, and unfortunately
wanted to use a different relay pin-numbering system than they did.

Can you say obtuse formatting? I knew you could....

The list of the parts in the standard library that was posted recently was
incredibly useful, for anyone who was interested in uncommon parts. And the
"pedit" needs to be replaced rather badly with a real editor, like uemacs.

The programs are quite useful, but there are things to watch out for: long
part names make it choke, even if they're the part name from the library.
Different sub-programs use different ways to end functions or climb the
function tree, from using "Esc" to using "F10" to hitting "B". This is
confusing, at best.

If a part-type is altered in the library, adding it to a board copies the
part-type on the board, not the new one in the library. This is irksome, at
best.

The directions in plib's help do not match the actual options. (AAck!)  And
if you don't have a printer on the system, and you're trying to load an
ascii file, and you don't tell it a filename to send bug reports to, it
fails to load the ascii. 

There are lots of potential improvements I'm sure we users could recommend.
I wonder if anyone from PADS is on the list, and would read them? Hint, hint,
hint?

I once designed a voice system using throat microphones used in pressure 
filled suits for inspectors in nuclear reactors. The microphone needed a 
special squelch design to eliminate the breathing noise, which were worst 
than the wind noises. If I had to do it over again, I would use a special 
foam that is probably used already in the audio industry, this 
windbreaker would use "Closed-cell" foam . Open cell foam is like a 
sponge, each cell has a hole so that you can breath through it, Closed 
cel foam would block air, hence noise reduction yet pass vibrations from 
voice.
On the other hand you could experiment with various kinds of socks!!

The easiest way is to use resistors.  A two way matching network uses
a 43.3 ohm and 86.6ohm resistors.

                             	----------------
				|
				\
				/ 43.3 ohm
				\
				|
		-----------------		75 ohm end
				|
				\
	50 ohm end		/ 86.6 ohm
				\
				|
		---------------------------------	


To the 50 ohm end, it sees 86.6 // (43.3+75) = 50 ohm
To the 75 ohm end, it sees 43.3 + (50 // 86.6) = 75 ohm 
I calculate a dB loss of about 11.4dB (sounds right, but I could be wrong)


This allows you to use the same "matching transformer" for going both 
directions.  Since resistors are used, frequency has no effect (until
you start to get into those frequencies where wire placements, etc have an
effect).

Since you really only need to match it from the 75 ohm signal into the
50 ohm spectum analyzer, you could just put a 25 ohm resistor in series with
your load.  Again, you will have a drop in signal (about 3.52dB -- and again
I could be wrong on this), but their is still no frequency effect.  That's
cheap.

Hi!

At a local trade show, I was looking through the local Computerland's
assortment of white elephant ISA boards, and I came upon an unopened
static bag containing a Tseng ET-4000ax based video card with 1M on board
A BIOS date of 1991, and a board manufacture date of 09-91 (etched onto
the circuit board).  The sales guy there had no idea what it was (even
though I did...  A brand new Tseng based board should retail for $125+.) so
he sold it to me for $25.00 (what a steal!).

At any rate, the board has no real identifying markings other than the
words "Super VGA" etched onto the board.  It has 8 80ns 256X4's mounted
on the rear of the card, just behind where the ET4000 is surface mounted.

Just in front of the ET4000 is a 26pin connector.  There is no card edge
connector on the top, so im assuming these pins take its place.


Can someone tell who makes this card, and how to contact them?

Thanks!

Hello everybody!

Got another programming problem with my 8051.

I am trying to get an LED to blink every second for 1 second using
Timer 0.  The program is supposed to Interupt driven.

I have been able to write the program using a polling method..  I just
am having trouble getting the Interupt driven program to work.

I want the LED to change state once every second..  So, for my 8 Mhtz
8051, that would mean that about one second would elapse after
Timer 0 has overflowed the FULL 16 bits 11 times.

So,  I have Timer 0 interupt enabled and wrote the interupt handler.

The handler checks to see how many times the Interupt has been called.  The
value is stored in R3.  Each time the interupt is called, R3 is incremented.
If R3 = 11, then one second has passed, time to change the state of the
LED.  If R3 <> 11, just reti.

THis is not working....  The LED blinks randomly for about 2 seconds, then
turns off and stays off...  

Anybody have any ideas about what is going on here?

   What you're looking for is generally called a "balanced" modulator (or
   mixer); it is, among other things, used extensively in generating
   single-sideband radio transmissions.  As a good starting place, I'd
   recommend the American Radio Relay League (ARRL) "Radio Amateur's Handbook".


that is certainly the convential approach, but something like the new
motorola single chipper which has just enough dsp umph to work on
audio would work very nicely, too (as long as you are trying to
modulate two audio signals, not one audio and one rf).

I'll look to see if I still have the schematic or an article reference,
but I built one of these once from an RE article, I believe.  It used
a real brute force approach: It was basically a small DC power supply,
a 555 oscillator driving a nice big switching transistor, and an auto-
mobile spark coil with high-voltage rectifier and capacitor.  It worked,
too.  However, it generated a fair amount of heat, and was capable of
delivering some hefty current, as I demonstrated when I put my fingers
on the heat sink to see how warm it was and brushed against the output.
Watched some fat, hot sparks dancing from my fingertips before I got
away.   In contrast, the little tower ion generator I got from DAK is
high voltage but very low current and no shocks.  Will post again if
I actually find the circuit.
