I actually went ahead and bit the bullet tonight. I swapped out the parts, used a different case bottom, and made myself a 475 out of my old LC.

Here's what I retained from the original:

-Power Supply

-Hard Drive

-Floppy Drive (though I did need to take a bracket from my LCIII to fit it properly)

-Keyboard, Mouse, Microphone, Monitor

-Case lid (it still looks like my old LC)

Here's what I had to swap:

-Case bottom

-Logic Board

-Fan

-Speaker

The problem I have now is the fan. The one in there sounds different than my original. I looked through my parts lot and found a Panaflo fan but it was soldered to another LC's fan/speaker mount. I'm currently in the process of fitting it to the connector used to attach fans to 475 boards (I hit a snag when I found out I don't have any solder). I'll be completing that process over the weekend so that I get the sound and everything of my childhood LC back.

I decided to go ahead and do it because of a childhood dream I had in 1995. I wanted to upgrade it to a 475 then. Unfortunately we didn't have the money at the time. I guess you can say it's wish fulfillment even if it does change an old friend around a bit.

I am impressed with the 475 speed.......and it runs all my programs fine and without the video problem! Now to try the Apple II stuff!!!
