Macintosh 512k Upgraded to run OS X – 24th Anniversary Macintosh Project

at 5:23 am. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, Electronic Hacks, Insane Equipment

Do you have an old Macintosh computer laying around? Why not blow off the dust and follow these simple steps to do an upgrade to OS X? You don’t even have to spend hundreds of hours creating the source code for the custom microcontrollers that interface the system together since it is available for free on the site. ๐Ÿ™‚

“This is a Macintosh 512k which I upgraded to run OS X by replacing the innards with a modern Mac Mini and various supporting components, including a grayscale CRT monitor, an LS-120 floppy disk drive, and a microcontroller-based USB device that interfaces the Mini to the original keyboard and mouse. Why? Mainly because I wanted to experiment with creating a custom USB device. Also I guess I wanted to waste hundreds of dollars and countless hours building a semi-useless computer with a 9 inch black and white screen and no arrow keys.

The most interesting part of the project for me was the circuit that allows the old original keyboard and mouse to be used with the Mini. It is based on an Atmel AT90USB162 microcontroller, which is basically a standard AVR ยตC with a special coprocessor dedicated to USB signaling. It comes with a C library that makes it relatively easy to create USB devices like HID keyboards and mice, speakers, storage devices, etc.”

    it should, it’s a mac mini–not a Mac 512k.

    So, I have an old 512k, and its been sitting around my house for a while….and I want to get rid of it. sell it more like:)….but anyway, I figured that there had to be people out there somewhere that knew about them, and you guys sound like you know what you talking about, so um, is is worth selling? if so, where can I sell it? how much could I sell it for? I’d appreciate it if someone replied to this, so thanks for your time in advance.

    […] problem in this instance lies in adapting something old to function in a new way. It’s like installing OS X onto a Macintosh 512K: it can be done, and it will probably work just fine, but the experience isn’t nearly as […]
