Wasn't that designed by some old curmudgeon?

I couldn't remember whether it was the same guy who did the MC4044,
or some other guy. I know that MC4044 guy did say something on
the matter in the past, but I can't remember what. Something in
me says the MC4044 guy did the MC1648, but some other guy did
the MC4024, but maybe I have that reversed.

Ah yes I remember it well, but sheesh was it realy 2002 ?
shame the drawings get screwed when viewed via google,
I wonder if theres an unscrew it up button somewhere.

top righthand corner of the page: click "fixed font"

or

on the message header: click "show options" then "show original"

Michael Black, You completely missed Michael Terrell's joke...

*I'm* the "old curmudgeon" who designed the MC4024, the MC1648 AND the
analog sections of the MC4044 (I actually suggested the algorithm from
which the digital sections were developed... and coined the phrase
"charge pump" ;-)

And I thought it was Arnold in his first mainstream movie ;-)

But seriously, I believe the first thing that they called charge pump
(well, ok, in another language) was this one from the 30's:

Did you get the Chritsmas lights fixed?

ah found it right at the top, I wonder what happened to
Win's fig tree he had to bury ?

I buried it for five years, digging it up each spring.
Each year it was little larger and a harder to put down
under 12" of soil. The fourth year it cracked as I bent
it and I worried if it'd be able to recover the following
spring. But the surviving parts did fine and delivered
the usual 100 fabulous huge sweet figs.

Then the fifth winter was brutal and we lost the tree.
It came up looking OK, but rapidly succumbed to rot or
something, failed to start leaves, and died. I may not
have sufficiently insulated the top of the root system.

However it did host a spectacular crop of bitter melons!

Next summer we planted a new fig tree, but it had a poor
type of figs that didn't finish within the season, and we
gave up on that tree after the second year. So, sadly,
we no longer have a fig tree.

Good stuff. But you've missed the audiophool niche.
When you gonna design a chip that yields "tweetier tweets"
or "woofier woofs" or a "skinn effect filter"?
Sheesh! The possibilities are endless ...

Merry Christmas!

Yep, I enjoy tweaking them. Particularly the ultrasound stuff... NO
BRAND out there I didn't have a hand in the analog front-ends ;-)

I wonder if he did anything for the Hewlett-Packard ultrasound machines
they seem to use in Nijmegen? H-P did seem to have their own designers.

And Diagnostic Sonar in Edinburough, Scotland would probablyn not have
bothered either.

No, I turned them to the side so they're not seen ;-)

I've considered doing just that.

So, it was another problem with a Digit-al solution?

Yep. A REALLY OLD curmudgeon. MRI next week to look at why I've
developed leg pain in my left leg only... sufficient pain to make me
limp :-(

...Jim Thompson

Look out for that. My dad had a clot down there (official disease name
escapes me, but will come back as soon as I send this...) and they
decided to 'bust' it with drugs. Unfortunately, clot bits then decided
to move around, causing strokes and heart attacks for a few years. Was
'the beginning of the end' for him...

but, that was 20 years ago, so hopefully they know a little more now!

Now,if I can just figure out what I did to my left knee...

My MRI came back with L3-L4-L5-S1 disks are "protruding"... probably
from a teenage injury ~55 years ago when I took a tumble down the side
of a rocky creek bed and landed square on my tail bone :-(

Another appointment with the doctors on Tuesday.

Thrombosis? Phlebitis? Thrombophlebitis? ...not sure there is a
difference.

The drugs are certainly better.

Now,if I can just figure out what I did to my left knee...

I did mine twice last month. ...and foot/ankle. I'm fine now
though.

That is one of the few times that I might recommend seeing a
chiropractor. They can sometimes get the bones to line up better...

Phlebitis was it! I think that the drugs they used then caused all
kinds of clots to bust loose, hence the problem. My dad smoked, ate
plenty of beef (he ran a meat packing plant...) and drank enough beer to
probably cause problems.

In the case of my knee, I built me a castle-block wall along the side of
the yard, one foot high by ninety feet long. Plenty of digging, liftin,
etc. Probably hurt my knee kneeling on the ground placing the bottom
ones...

I have a set of knee pads that I wear for such tasks as laying tile
flooring ;-)

My doc doesn't think this particular case is circulatory, based on
such old-fashioned things like comparing hair growth on the toes of
both legs... hair growth matches side-to-side, but right leg is just
fine.

What's scary is the doc issued me a _permanently_ disabled parking
tag, so I don't have to walk long distances :-(

When I had my heart attack (1998) I was given "tPA" which _dissolves_
clots.

I see a spine specialist on Tuesday.

Anyone here had bulging/protruding disk repair?
