I haven't done the palm upgrade (I don't have a palm pilot), but I did replace the 32k sram in my hp48g with 128k sram.
The sram was surface mount... I just used solder braid to get it off the board.
Soldering on the other chip was challenging, and even more so as I have shaky hands. I clipped tiny segments of solder off of the solder spool using an exacto blade... the pieces were maybe 0.5 mm to 1 mm long. The solder had a rosin core so the pieces were like donuts. I then stuck the pieces onto the leads of the sram and placed the sram on the solder pads on the board.
With the small amount of solder in place, I didn't have to be tremendously steady with the soldering iron. I did manage to bridge a couple pins, but the exacto blade separated these as well.
I suppose you could use solder paste, but I've personally never had much luck with the stuff.
I wasn't too familiar with electro-static discharge at the time, so I didn't use a wrist strap. But this was in missouri, and if you have something like 40-50% humidity static usually isn't a problem.
years later I am still using the same calculator.
so anyway, surface mount isn't always that hard to manually work with.
That is a really interesting way of looking at digital info. Somehow I never thought of my favourite mp3 as a binary representation of one big number. bizarre.

In my closet there exists a sock that has not been used (by foot or any other appendage) in a little over 6 years. In all likelyhood I'll never wear this sock again. But guess what? YOU DON'T MAGICALLY GET THE RIGHT TO THIS SOCK! IT'S MINE, DAMN YOU!
I suppose this is nit-picking, but I actually am less intelligent, definitely less morally concerened, and usually "wrong." (when compared to a jon katz, or any other type of rock)
I think that innovation and ground breaking developments are created by the individual rather than the group at large.
Open source lends itself to debugging, tweaking, and general enhancements--but there is nothing inherently innovative in the process.
It is far easier to be the editor of a book than the author. Innovation is the spark that starts the fire. The opensource community feeds the fire, builds park benches around the fire, and brings the marshmallows. But the fire was still started by the individual

I use remote display every day at work. Life would suck without it. Also, I don't play any games at work. If games are so important to you, you should consider a console.
A 30GB drive costs something like $190. That is 30,000 MB And you are worried about an executable that is 1 MB in size?

I believe most dram chips automatically write back to an address after it was read. So forcing a read of all the address would infact refresh the chip.
The plot of the measure of something learned against time or number of trials. In computing, it is often mis-used to mean the amount of time it takes to learn the usage of something ("reduce the learning curve") or the ease it ("easy learning curve").

I don't think supporting cell phones is very interesting. That is expensive, and where could you possibly be using this thing that it would be easier to use a cell phone instead of a regular cheap phone jack? The park? A movie theatre?
However, what about bluetooth and related short range wireless stuff? Since these things are small, and potentially have their own screen, wouldn't it be better if they created a sort of wireless lan based on proximity?
You and a couple friends bring your playstations into the same room, and blammo, you are networked or whatever. It would raise the cost of the ps1, but at least it would be useful.
"Just because 99.44% of its users are shuttling crappy, copyrighted material around doesn't remove the usefulness of the program. "
That is just silly. That is *exactly* like saying a nuclear bomb may kill 99.44% of the people within a certain vicinity of detonation, however one person on the fringe was cured of cancer due to "free" chemotherapy.
Your assumption that I am male is correct. (At least it was the last time I checked.)
There isn't a specific androgenous term of respect in English, that I am aware of. But I am not a linguist. The best I can think of would be "Dear Sir or Madam" which is used frequently.
My comment about "What grade school..." was almost sincere. I was in grade school when I would think about these thing. I wasn't trying to correct the AC. I was answering his question.
Why is this so exciting? Is it really that difficult to put multiple processors on a die? And this sounds like they are just putting multiple die in a package. Oddly enough, I believe it is referred to as die and not dice when speaking of pluralities in ICs
When a die gets large, you have thermal expansion problems, so one can't just stick four pIII's (or whatever) on a single die, it gets to large. But you could stick four pIII die in a single package. flip chip might not be the best way to go about doing this though.
fyi, a company I've worked for in the past makes a multi-chip module that incorporates 5 die. Not all are processors though, a couple are cache.

sorry for being rude. I thought you were trolling.
yes, anisotropic etches are possible. They happen all the time...crystal fault delineation, dopant preferential etching.
I haven't read the article though, so maybe in their context it is wrong...

A Micron is a Micrometer. 1E-6. An Angstrom is 1E-10. There are 10,000 Angstroms per micron.
You did manage to get nanometer correct.
Out of curiosity, did you just make these numbers up, or did you read them somewhere?

it looks like a dial to me, not a microphone. Perhaps you dial through the letters, hit a button to go to the next spot, and dial some more.

I think you just fed a troll. the non-english word "retarted" gives this troll away.
