Alternatives to ROM. Magnetic vs. Electric

What are the advantages of magnetics vs. electrics?

It's a matter of personal preference.

I don't use zip, unless I really need to. So far, I've never had to.

Winzip is a pain in the @$$.

Is the ROM built into the keyboard?

Interesting. In '90, I had a green monochrome Corona PC. Its keyboard
did not connect to the PC via pins but rather through a cord
resembling a telephone cord. The plugs on both ends resembled that
used for telephones.

What are the alternatives to ROM?

I am aware that there is nothing objectively wrong with ROM. However,
as a matter of personal preference, I would like other alternatives.
It's like preferring garlic over onions [or visa versa].

 

[.... much snipped ....]

There are no electro-optical nonlinear effects that you could use to
do the same trick. It is a very new area of physics.

[... snip ...]

No its more like preferring garlic over gravel. All the other ways of
doing are either ROMs in funny cloths like a CPLD or buckets of
decrete logic.

 

I prefer the discrete logic over the ROM.

 

But for no apparent reason, right?

I like things to be lively. Discrete logic is far more effervescent
than ROM.

 

But it isn't more effervescent. In order to make disscrete logic
perform a given operation, the gates must be wired in a specific way.
This wiring is where the information is stored when you use descrete
logic. The wires remain the same so the information is always there.

If you look at the internal design of a PROM, you will find a large
amount of logic and an array of some sort of electronic switches. Way
back in the past the switches were little fuses. The process of
programming a PROM was to burn the unwanted fuses to beak the unwanted
connections.

 

Radium is a troll. He gets his jollies from seeing how many people he can
get to take him seriously. This isn't as bad as the usual way-off-topic
insult-slinging troll, but he still isn't worth the bandwidth he wastes.

 

I see no evidence that he really is a troll. Merely being wrong isn't
trolling. Do you have some previous experience with him?

 

In many ways it's worse than the insult-slinging type
because Radium sucks innocent bystanders into conversations,
people who don't even realize Radium has no purpose, that
some discussions are just repeats of same thing Radium
posted previous months or last year.

 

This is what I would like. Hardwired logic as opposed to software
programming. In hardware logic, the information "stored" and
"programming" is determined by the way the chip's circuits are
mechanically built. When an electric current is passed through a
certain of those circuits, specific signals [of instructions and
information] are generated. Depending on an individual's view, this
may or may not be a type of "ROM". Even if it is, I still like it
because this "storage" is really determined by the way the circuits
are physically-designed; hence the instructions are freshly-generated
each time electricity is passed through the chip.

 

Which means...what, exactly?

Bob M.

 

What a *horrible* thing, to be sucked into a conversation. Maybe
you'd rather join the kook invasion?

Sure. Noone is forcing you to read or respond, though sometimes
something interesting pops out of the strangest threads.

 

If you want lively, you can't beat Monkeys flipping switches. That
would make it a biological processor.
Logic density kind of sucks though, maybe one Monkey per square foot,
but you can stack them. You'd then have a 3D biological processor -
cool.

Worked a treat for the early space program.

Dave.

 

It IS ROM. You give a certain input to it and you will get a certain
output, every time, just like ROM.

So now the no-ROM issue out of the way? Great, now maybe somebody can
show you the light about magnetic storage and other stuff pPp

 

Yes. As long the ROM-signals are determined by the way the chip's
circuits are mechanically built. When an electric current is passed
through a certain of those circuits, specific signals [of instructions
and information] should be generated.

Nope.

The only thing I'd like to use magnetic signals for is described in
here:

http://groups.google.com/group/Crea...egen1+magnetic&rnum=15&hl=en#d57c8a76f8118694

Quotes from the above link :

"I would like to make some replicable magnetic electronic nanobots
that will search for sample playback MIDI synths, softsynths,
emulations, and soundfonts in any part of the world and attach to the
digital chips of sample playback MIDI synths, softsynths, emulations,
and soundfonts. These nanobots should contain magnetic receivers that
will extract any random environmental magnetic audio signals from 2
kHz to 50 kHz [excluding spikes, square-waves, white noise, brown
noise, pink noise and bass sounds]. The nanobots then amplify those
signals to the point where they would significantly interfere with --
and cause inductive crosstalk in -- the audio signals in the digital
electronic chips of the sample playback MIDI synths, softsynths,
emulations, and soundfonts. This will cause sample playback MIDI
synths, softsynths, emulations, and soundfonts to be full of annoying
-- and perhaps even frightening -- auditory disruptions from
environmental magnetic interference**."

"**Note: The magnetic signals that interfere with those digital chips
should be purely-analog. I just love it when purely-analog magnetic
signals cause significant disruptions in purely-digital chip-based
parts of electronic devices that I don't like. Sample playback MIDI
synths, softsynths, emulations, and soundfonts are an example of
digital electronic devices that I don't like so I want to victimize
them in this manner -- i.e. via magnetic interferences."

 

Usually there is some purpose w/other posts, it's not just a
black hole of wasted time. Radium can tend to play on
other people's generosity in that they don't yet realize
there really ISN'T any purpose at all.

Yes, sometimes regardless of the senselessness, something
interesting pops out. Now pause and ponder for a moment
that given that number of participants and their time, used
differently these resources might've produced something even
more interesting.

Basically you're just wrong though, if you lack interesting
topics in your chosen forum, the answer is not to wait
around for a troll, it's to find something that DOES
interest you.

 

That would be bubble memory.

*YOU* are wasting your time. Radium isn't.

You're the one who has made the CHOICE to waste your time. You can
easily kill the entire thread.

Every participant is in exactly the same position as you. They have
all decided that it was wort their wasted time to respond. You have
a problem with that?

If I've responded, it obviously does interest me. Unless you are a
complete idiot, you are no different.

 

That would be a "masked ROM", a fuse or anti-fuse PROM. In each of
these there is a mechanical difference between a location that is a
one and a zero.

Stuff like the microcode in a processor is masked ROM. The micro
inside your keyboard and video cards are likely also to be masked.

Parts like Flash Proms only have electrical differences between ones
and zeros. If you are making less than a million of anything, the
Masked ROM is likely to be too costly of a way to go.

 

I don't think CPUs (since the Intel Pentium FDIV debacle) use masked
ROM. Or at least, not exclusively. Large portions of microcode
are loaded by BIOS to permit relatively easy bugfixes. CPU mfrs
provide a binary lump to BIOS writers. AFAICS, the microcode gets
loaded each boot into something analogous to SRAM. (DRAM?).

Or if modifiability is important. It is for CPUs, and probably also
for GPUs.
