68 Katy – 68000 Linux on a solderless breadboard

68-katy-protoboard-final

Steve Chamberlin of Big Mess o’ Wires has written up documentation on his awesome 68 Katy project,  a 68000 Linux on a solderless breadboard:

Here’s a look at the final version of the hardware. It took about a week to assemble and wire up all the parts on a solderless breadboard. 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. The CPU has 20 address pins, allowing for 1 MB of total address space. It’s paired with a 512K 8-bit SRAM, and a 512K Flash ROM (of which 480K is addressable – the remaining 32K is memory-mapped I/O devices).

Check out the video after the break.
