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. > This chip, the one that takes the 8 inputs (AKA address) and

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].

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. -----------------------------------------------Reply-----------------------------------------------

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.

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

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. -----------------------------------------------Reply-----------------------------------------------

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.

It IS ROM. You give a certain input to it and you will get a certain output, every time, just like ROM. >Even if it is, I still like it

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. > Great, now maybe somebody can

Nope. The only thing I'd like to use magnetic signals for is described in
here:
http://groups.google.com/group/Creative-Music-Synth-220/browse_frm/th...
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."

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 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?). > Parts like Flash Proms only have electrical differences between

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

Oh, don't worry, mechanical is how all them ROM works, none of them nonsensical magnetic whatchamacallit you hate so much. You send specific amount of electron particles constituting a current moving through nuclear-mechanical paths, it makes other particles move in predetermined nuclear-mechanical pathways, makes holes so that actual particles can move around and such, and finally all these nuclear-mechanics causes specific amount of electrons constituting an output signal to be produced at the output end.

In other words, you would like to effectively destroy the rest of the world just because they don't follow your preferences. That sounds like... your full name is really Osama Bin Radium, isn't it? :P --
A Lost Angel, fallen from heaven
Lost in dreams, Lost in aspirations,
Lost to the world, Lost to myself
