Watch this video on YouTube What does it take to build a little 68000-based protoboard computer, and get it running Linux? In my case, about three weeks of spare time, plenty of coffee, and a strong dose of stubborness. After…
It’s been roughly a year since I turned a personal electronics project into a retrocomputing mini-business, which makes now a good time for a short review. When I started dabbling in floppy disk emulators for vintage Macintosh computers, I never…
Still working on the uClinux bring-up for my 68000 protoboard machine. Still not there. Why is this so hard? Yesterday the boot process was working up to the point where it tried to mount the root filesystem image. I finally…
So close to a successful boot, yet so far away! I’m continuing to work on porting uClinux to my 68000 protoboard computer. Since my last post, I’ve added hardware to support timer and serial interrupts, and shrunk the linux boot…
What you see above is my first attempt to boot a uClinux 2.0 kernel on the 68 Katy prototype hardware, the result of several days of work. It doesn’t look like much, but the fact that it even begins to…
