Designing a 68K Single Board Computer
Hackers of a certain age love the 68000 family of CPUs, and I’ve begun sketching out designs for a 68K-based single board computer. Take a vintage off-the-shelf CPU, add ROM and RAM and an SD card and some type…

More Thoughts on Homebrew CPU Linux
The other day I wrote about designing a new homebrew CPU, and getting Linux running on it. After looking deeper into the idea, it’s just not realistic to port Linux to a CPU that I built myself, even a low-end version…
Acrylic, Wood, Hardboard, Oh My!
The revision 4 Floppy Emu cases are here, and they look great! Clear and black acrylic in different layouts, birch plywood, and chocolate-colored hardboard. I’m having too much fun putting these together. The purpose of revision 4 was to test a…
Porting Linux to a Homemade CPU
Wouldn’t it be cool to create a homebrew CPU architecture, then port Linux to it? I realize that single sentence probably implies a couple years’ worth of work, but that’s OK. A real, full-fledged OS running on a totally custom…
Designing a Laser-Cut Enclosure
An official laser-cut case for Floppy Emu has finally arrived! It took a lot of prototyping and fiddling with tiny parts, but I hope you’ll agree the result was worth it. The case is only 6mm larger than the board…
Raspberry Pi 3D Performance Demo
I’ve recently gotten interested in 3D programming for the Raspberry Pi. I’m not sure why RPi 3D development interests me when desktop 3D mostly doesn’t – I guess there’s just something fun about coaxing as much 3D performance as possible…
