I picked up an Amiga 500 from the local Freecycle list thanks to my wife's sharp eyes. I've fired it up and it works fine, but I decided to pull it apart to see what makes it tick and it's a great thing to look at for electronics people because the whole thing is through hole and big enough to poke at. I've gone through the chips in the video tear-down and covered a bit of the history. The camera work in the video isn't great, I need some practice so I thought some accompanying static photos that you can look at might help.
If you are interested in this retro-computing tear-down video feature, let me know, I've got a heap of other 80's era home computers that I can take apart on camera. There's another article with some schematic info about the plug-in memory and RTC board I showed in the video, just waiting for a part to make that work again.
