Details

What are you trying to do?

  • Take an LC575 and rip out its insides and insert an AMD system?
  • Somehow replace the LC's processor with an AMD? (which would be completely impossible)
  • Build a Mac/PC hybrid that can run both OS 9 and WinXP with 2 motherboards inside?

Note to all new posters: We're not mind-readers here on AF. We need details!

lc575 to amd

I'm going to replace the guts with a new motherboard, and processor, power supply. Any thought on what motherboard would work best? What my major concern is the video. With the trinitron on the lc575 work well with the new hardware

mini-itx motherboard - mini-i

mini-itx motherboard - mini-itx.com
processor included
power supply also can be purchased here

a full size ATX or even a Micro-ATX will barely fit in there... I tried a Micro-ATX to 5500 once and it didnt turn out well.

i am not a monitor pro but i believe it should work as long as you keep the original power supply for the monitor the same and if the pinouts are the same.

if you put the mini-itx in you might even have room for a mini and a KVM switch *wink*

the only downfall of that rou

the only downfall of that route is it isn't AMD... it is compatible though. there are a few AMD Mini-ITX boards but they are more expensive unless you go with the AMD-Geode boards which are cheaper but only run linux and WinCE.

the real question should be "can i record anything from my microphone jack into itunes windows?" this i do not know the answer to. also you probably should have created a new topic.

Yes but you will need 3rd party software, you can't do it directly from iTunes.

Wow, that has got to be an all time record for most-est off topic post.

The video might be challenging. Keep in mind that there isn't just a regular VGA video connector inside there. I have personally had difficulty getting an LC575 monitor board to sync up with an external Mac. You will undoubtedly be successful, and will post back here how you did it Wink

video pinouts

I have the pinouts from the mac lc575 and the video on the new motherboard. If its as easy as maching the pinouts...It will work fine. I just feel unsure about it being that easy.

Even if you do get it to work

Even if you do get it to work, it will only probably look decent at 640x480. Mounting an LCD monitor will provide a much better experience, but it would be at least the cost of a 14" LCD monitor and at most the cost of custom panels and controllers.

1/2

then again may be the cost of the 14" lcd will free up space for cheap full size pc components. so it should equal out in theory...

I don't know.. my Mini ITX board was only $100. Granted, it doesn't have TV-out, but that's a small tradeoff.

it isn't.

PCs and modern Macs receive data from the monitor about what resolution/frequency it can do and then choose their resolution based on that. The display inside a 575 won't provide that information, as macs of that era use a much different method of determining what resolution to run in (sense lines that are either open or closed).

If you're going to put a PC in there, try finding a cheap LCD of approximate size, or an even cheaper VGA monitor of the same size, carefully gutting the 575 and puting the new display inside it (make sure you follow safety precautions for working inside monitors. Unused for years these systems can still hold a lot of charge)

I'm curious, is there any documentation on how modern monitors provide that information, so that those of us that would like to can fake that info?

This is my previous research on using older monitors (which would include the 575, whose display is basically the same as an Macintosh Color Display monitor) with a modern Mac video card:

However, I would repeat that I have never gotten the 575 analogue board to sync and "crackle up" without the motherboard, which I *have* been able to do with a Color Classic analogue board. I don't know why they are different, but knowing how to fake modern VGA ID signals might help me out.

i dont know for sure a bout t

i dont know for sure a bout that because i have two 10 year old IBM monitors that work fine... the computer thinks they are generic monitors so it knows there isn't "label" on the monitors that tells what it is... in other words... i have used un"labeled" monitors on modern system's fine.
