Its not that 32bit machines are incapible of functioning or doing whats required, and it's not that 64bit machines provided any new functionality that cannot be replicated with older systems, the ONLY aspect that obsoletes older systems is the speed at which they accomplish the task.

Yup, after some work. (Harder to do when source isn't available.) There are software OpenGL renderers that are Mesa compliant and drop in place of a hardware implimentation. The rest is asking id to not use -mcpu=pentium when comping. If they refuse, I can emulate a pent instruction set via trapping.
Actually, quite a few. Both have even updated their 386 models within the last few years. 386's are still considered a workhorse cpu for the embededded market.

See my url... The world has yet to move to a point where my 386 can't operate. It may be slow, but anything you can do on a nice big fast 64bit box, my 386 can trudge through as well. If we haven't obsoleted the 386 completely yet, I think 32bit x86 has a LONG lifespan left yet.
A DVI plug does not mean DIGITAL. DVI connectors have both analog and digital signal pins on them. Most LCDs can use either as a source. So unless you have an LCD that will tell you it's running off the digital side, or can ONLY accept digital on a DVI cable, you don't know which you are running.
See the url above. Those 'dead' architectures that noone's using, the very fact that they ARE maintained demonstrates someone is using them enough to keep it working. Myself, I push a 386 and a SE/30. Both are more than fast enough for my purposes.
Many people don't have the luxury of grabbing a P4 or Opteron as there whims demand. Supporting older hardware also does not slow an OS down. If done properly, it forces you to think about how to do things RIGHT so you don't eat unnecessary cpu cycles.
Given what I've seen so far, I wouldn't run out into the streets proclaiming this the pinacle of software quality. The interface is a nasty cludge of Apple brushed metal on the shell, and mixed windows widgits inside. It acts like the main window is renedered by hand in a back buffer than just slapped over the designated window space instead of attempting to use the themeability of the default Windows GUI APIs. Net result, resizing is PAINFUL on a box that isn't doing anything. The plain, undecorated dialog when you hit a station in the radio tuner while it pulls down the playlist is nicely out of place as well. On the mac it just reports that in the LCD display, why couldn't this build? Nice app, but man the spit and polish once you try to do something is lacking.
Thanks to pr0n we have streaming media, audio/video confrencing, lots of browser enhancements... a gigantic chunk of the tech you see on the net was probalbly pioneered and pushed through development by the pr0n industry. So scary as it is, yeah, supporting pr0n IS doing something productive. : )
Current G4/G5 systems like to provide power for ADC displays through the connector on the video card. The supplied voltage is 28v. So they'd either need to put DC TO DC converters on the motherboard to step up one of the avaiable voltages, or just let the power supply handle it. Having the power supply handle it also gives them a convient method of requiring Apple parts in their boxes.
I wouldn't have thought such a puny core as a G4 could have so much back pressure, but they do! Damn thing locked the tires at 35mph using 5th. It wouldn't have been so bad but it's a FWD design. THAT was an interesting ride. Thinking I could out wit Jobs, I tried it going down hill backwards, tranny in reverse. Imagine my surprise when I discovered reverse was meerly a placeholder, and wouldn't be available till 10.3 shipped, and the brakes don't work unless the cpu is running, 'cause who'd need to stop if the cpu is dead? Fortunatly I ran into the side of a SUN Wildfire box which stopped me dead, and my SCO insurance agent assures me that the whole accident was SUN's fault from the begining.
Yup, I did. If you read them all, you'll see they all discuss Yikes/Sawtooth era G4's, and G3's, which used 20pin connectors with no 28v provision. The others are for earlier PMs that differ a bit more (inverted power on signals, etc) so while the info is good, it's not directly applicable. A few mention that Gigabit and newer systems that support ADC connector sporting video cards have a different (22pin) connector and require 28v, but don't go into any further detail. It's left to the experimenter to determine just how different the 22pin systems are, which I've sat down and done now.
That details the modifications needed to get 20 of the 22 pins correct. Apple used the same connector keying on the 22pin header as the normal 20 pin ATX header, so your connector will slot right in where it needs to. Once you have that, you need to supply 28v, which is a task I leave to you. Right now I'm using lamp cord pressed into the socket for a 'connector' and tapping the still functional 28v output of my bad supply.
http://members.aol.com/adapterpros/
They claim to have a harness that takes the output from an unmodified PC ATX power supply, plus a feed from an external source, that terminates in a Gigabit compatible 22pin header. The extrnal source is a 28v wall wart that uses a custom slot cover to pass the line into the case and to the harness. I've email'd them but haven't heard back yet as I'm interested in trying it.
I'm also documenting everything I find for a writeup on my own webspace so people don't have to hunt and fish for info then piece the bits together themselves like I've had to. Once I have enough posted for it to be worthwhile, I'll see if Slashdot considers it worthy of the Apple section.
Actually, it NEVER was the front panel board. If you research what Apple did handling those cases, if under warranty that is... They would replace the front panel, as well as the motherboard and power supply, 'just to be sure' in one shot. If you were out of warranty, you were SOL as many had replaced the front panel board after refrencing that article, with no luck. Given that the board itself used pulls $50 dollars for a part that doesn't fix the issue, the thought of spending $150+ on a power supply, or $300+ on a motherboard next with nothing more than a hunch to direct you directed most to just buy a new machine.
For refrence, I don't use the front panel board, I have a power switch wired direct. : )
After submitting the question, I resumed scouring the web and got a bit braver with my parts...
After reading up on some G4 to PC ATX case conversions, and doing a lil guessing, I determined that the G4 power supply should use the same power up sequence as an ATX. What threw me off is earlier PC ATX power supply to mac conversions had to invert the power on signal, and I incorrectly assumed Apple did the same with the G4.
http://www.xlr8yourmac.com/systems/ATX_G4_AGP_co nv ersion/G4_AGP_to_ATX_case_pg2.htm has the mods that get you 99% of the way there, you just need to supply 28v to finish the job on any ADC capible G4s. Once I figured this out I had the system booting off a PC power supply (and the 28v trickle from the G4 supply). I bench tested the G4 supply, and sure enough, shorting the power good, which should have fired it up just bliped the power. Based on the symptom set, it seems pretty likely this is whats affecting others. The test is simple, use a paperclip or something similar, short the green power up line to a black ground line, and see if the power supply fires up. If it does, it's the mobo, if it doesn't, its the power supply. No more throwing batteries sacrifical virgins at the problem while performing dark rituals around the CUDA switch.
And for those curious, the machine I'm building is a FrankenMac, assembled from random bits on eBay and my parts closet. I've TRIED talking to apple stores, but the instant they figure out its not a boxed apple, they tell me to pound sand. I've got $75 into the power supply, so I wanted to be ABSOLUTELY certain it was the culprit before canning it. Unfortunatly, while Apple will offer some simple diagnostic guidelines, they won't give you all you need to do this sort of work outside of an Apple authorized repair depot.
So, any dns worm that launches a DDoS, like say, msblaster, that launches an attack against say, windowsupdate.com if it resolves, will now attack Verisign's root nameserver instead? Interesting...
I heard about this on Saturday when a roommate brought home a fax, from C I Host, spammed to their fax machine. It did identify itself as being from C I Host, why it was sent to that fax machine, we have no idea. (It was most distinctle NOT requested.) Rather than do their own writeup they just reprinted APWire's text on the case.
Everyone's getting all in a flutter 'cause DRM was mentioned. Who cares? If you want to copy software, use your pc and move on. This is just a dedicated box + Steam'esqe delivery. Personally I'm looking forward to it. My main grief with consoles is many games are only good for a short while. Sure, I could rent, but that adds up quickly. Give me a low cost subscription, and a large library, and I'll put up with delays while downloading a game quite happily. Do I give two !@#%s that there's DRM preventing me from using my PC to access the service? Nope. Wah, I can't rip the games off the box. This is akin to calling scrambled cable DRM and calling for a jihad against the cable companies for it.
If Microsoft can argue, and win, that something as obvious as a Graphical User Interface which Apple came up with first does not belong to them(before you start I'm a PC User), what right does this office have to say that something as simple as a single click, an online auction, a transparent cache and so on, is a process that someone can say is exclusively their technology.
Someone else will likely respond to this as well, but Apple did NOT invent the GUI. Both Apple and MS got the idea from the Xerox Star system. There is also much prior evidance of the concept in pre mac platforms, albeit much cruder implimentations.
Problem is, the false positive count is more on the magnitued of 75%+ of all notices sent out. For starters, if you specify force ip in your gnutella client, they report the forced ip, NOT the one you're actually serving content from. (The push system makes spoofing so easy it's silly. All you need do is setup your ip as something completely bogus, and as long as they don't make a dl attempt, which I have yet to see, they don't know your real ip.) I've seen and tested this, they just report the wrong ip, never downloading the content, just doing file name globbing.
As far as them having access to ISP laws, sorry, no supenoa, no logs for you, no discussion.

Actually, I've seen model RC jet aircraft that I could easily stow in a briefcase so it's quite possible this is a really a jet powered vehicle.
As far as the flight dynamics, who says you can't have a low speed jet?
Best I can offer is my Cyrix 486 DRx2-66 running FreeBSD 4.9p1... See link above. : )
