The heart of the system is a Motorola 68008 CPU, a low-cost variant of the more common 68000, with fewer address pins and an 8-bit data bus. It took about a week to assemble and wire up all the parts on a solderless breadboard. Here’s a look at the final version of the hardware. I’ve named this plucky little machine 68 Katy. Having a full-fledged multitasking OS running on this ugly pile of chips and wires is a thrill, and opens up all kinds of interesting new possibilities. After banging my head against the wall with problems ranging from the inductance of pushbutton switches to memory leaks in the C standard library, it finally works! I’ve built several other DIY computer systems before, but never took their software beyond simple assembly language programs. 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.
