This is from the Microprocessors Unlimited Catalog. UP Ultd is in Beggs OK and
advertises in BYTE, PC Week and other magazines. The Dynamic ram prices are
quotes from Worldwide Technologies. They too advertise in BYTE.

          Type                         Price        Price/Meg   
Real Static 128K x 8 (70 ns)           $23.00       $184.00
Psuedo Static 512K x 8 (80 ns)         $27.00       $54.00
Dynamic 1M x 9 (70 ns) (9 chip)        $37.00       $37.00     
Dynamic 1M x 9 (70 ns) (3 chip)        $35.00       $35.00

So as you can see Psuedo static is much closer in price to dynamic than
statics but is closer to statics in packaging (32 pin DIP x 8 organization
instead of a SIMM), and ease of use (no externall controller required).

I was wondering if there is such a tape, I have chosen to make a test tape
on a friends sterio, various freq. switching between various channels.
But to adjust the tape head there is usually one of the screws that has a 
spring and a washer under it. the head it pivoted on the other, fixed screw.
I think there are ones that have both screws adjustable.

Hello netters...

I need a couple (9 to be precise) of 450 mAH nicads.  Problem is they need
to be N cells.  Radio Shack sells N size nicads but they are only 150 mAH.

I need to replace the batteries in my old 2 meter HT.  After 10 years the
originals cells and many recharges, the original cells have finally bite the
dust.

Can anyone point me to a source?  I tried the original manufacture, but they
want a small fortunate in addition to my first born child.  Surely, it can
without giving up the child (if I had one to give). :-)

Thanks for the help.

Note, though, that any frequency measurement using something other than
a scope relies heavily on assumptions about waveform.  When I first got
my current scope, I hoked up a little audio-frequency square-wave generator
with a 555 as an independent test signal.  I was a bit surprised to find
that my frequency counter read twice what the scope showed me.  Turned
out that the leading edge was sloppy enough to double-trigger my rather
sensitive frequency counter.  There is no substitute for seeing exactly
what's happening.

There's something else...I'm not 100% sure about the original Soundblaster,
but a lot of the clones have an AGC on the input...you'll get a meaningless
number if you try to read it statically, unless you somehow disable the
AGC.  There is no software switch on my Thunderboard to do this, and there's
no schematic in the manual, so I haven't tried to modify it.

Also, programming information on some of these boards is pretty sketchy.
I can't figure out how to statically read my TB, either - I sort of know
how to do DMA sampling, but I haven't gotten it to actually work yet.  I
have the Unix driver sb.c (on internet), but would love some DOS "C" code,
if anybody's got it.

>Couldn't you use a game(joystick) port?

Not likely.  The PC joystick isn't an A/D converter, it's an op-amp
functioning as a comparator.  Think of it this way: if you have an
R-C time delay,and you charge up the capacitor all the way, then remove
the charging voltage and put the resistor across the capacitor.  You can
figure out how long it will take the voltage across the resistor to drop
with the time constant formula, R*C.  If C stays the same, and you
put a comparator looking for, perhaps, 0.63 times the charging voltage,
you can measure the "R" value with a timer and a one-bit input.

That's how a PC joystick input works...when you call the "READ JOYSTICK"
routine in the BIOS, the routine charges (or discharges, I'm not sure which
way it works) the cap, lets it discharge through the 'R' (the pot on the
joystick), and measures how long it takes to charge/discharge to a certain
voltage.  It's not very accurate, but it's certainly good enough for
game playing.  Putting a voltage on it wouldn't work very well, though.

Incidentally, the fact that the computer is doing the timing with
tight loops is why joysticks don't work too well in Windows.  Windows
mucks up the timing.  My 486-33 doesn't like the joystick at all.  I
have an AMI BIOS, I have heard rumors that other configurations support
the joystick just fine.

Yes but they do so with a large AC line-powered compressor plus a large 
storage tank (a "battery", if you will), and the things that are powered 
are relatively small.  

An air tank big enough to replace the gas tank in even a lightweight car
would be much bigger than the car.  Fittings and so on to handle that much
pressure  would be "interesting".  Especially the non-permanent connection to
the air pump at the "recharging" station.

Actually this is an advantage.  First of all by doing all the "burning" in one
place, you can realize economies of scale.  Second, it will generally be
cheaper and easier to install one really good pollutant filter on the power
station's stack than to put little ones in all the cars.

Tweeters usually fail because of excessive distortion in the amp;
frequently clipping. The amp may be clipping even though rated at
250w. Also, if there are loose connections, dropping stylus on records,
etc. that create transients, these can damage tweeters.

This is totally true, and totally misleading.  Your bit about "Without
a UV filter" is the heart of the problem.  There are no such things
as desk lamps without UV filters in the United States of America.  Safety 
regulations have required shields on halogen desk lamps for years, perhaps 
forever.  You are talking about a safety problem which does not exist.  

Fearmongering at its very worst; a half truth turned into a whole lie.

Unless you remove the UV shield from your desk lamp, there is no danger
from them.  Take a look at a theater stage some time.  They aften use
100s of Halogen lamps which are typically between 500-2000 watts (10 to
40 times a powerful as your punny desk lamp).  If what you said was 
true, then actors would be sun burnt after every show.  They are
not because their Halogens, like your desk lamp, is UV shielded.  Any
glass or plastic cover will do it.

It may vary from state to state, but here in MA a physician has

I've heard this guess from a couple of people and it seems reasonable to 
me: intercourse helps cramps because the cervix is massaged. Massage with
the fingertips works at least as well as intercourse does, at least in my
experience and that of the other women who suggested this interpretation.

My 75 yr old Dad is currently in the hospital undergoing tests.  A

that it is not a textbook case of AML; bone marrow tests showed
a lack of cells (appeared empty?) rather than a proliferation of
mutant cells.  A blood test taken 6 months ago was completely
normal.  

My Dad is feeling a little weakened now, but has generally

You dragged it in as if it was part of your scientific studies,

you are too emotionally bound up with the fat stuff to be objective
about it.  Nobody is saying you have to have extreme hyperphagia
to get fat.  Just another one of your straw men that you set

This is very unfortunate news for all of us.  A lot of good research has
come out of Canada lately.  Many of us here in the States have noticed a
drop in domestic output corresponding to cutbacks in financing during
the Reagan/Bush years.  An increasing percentage of the best studies in
the journals I read has been coming out of Canada, Europe, Japan, and
elsewhere.  The fact that good research is coming from more countries is
of course good.  The fact that less is coming from here is bad.
 
In other bad news, Sunday's NY Times has an article entitled "Germany
Approves Health Care Reform to Cut Medical Costs".  Some excerpts:
 
    The German Parliament has approved a package of health care changes
    intended to curb the surging costs of medical and dental care by
    making patients pay more and forcing doctors, dentists, hospitals
    and drug companies to cut prices...
 
    The plan is intended to save the Government $6.8 billion annually...
 
    German dentists have responded by threatening to refuse to accept
    patients from the state-backed health insurance system...Pharmacists
    contend that nearly 30 percent of the medicines they sell will no
    longer be available to public health patients because of new
    restrictions on what can be prescribed...
 
    The Government says health care providers' fears are exaggerated and
    that the quality of care will not be adversely affected.
 
Perhaps these two stories have more of a connection than meets the eye.
I have heard it suggested, although I can't remember where, that funding
research is doubly expensive.  First there is the cost of funding the
research, then there is the cost of funding the new technology to apply
the knowledge gained.  Maybe we are being told that there is already
quite enough medical knowledge, thank you.
