Starting a “Cold Fire ” Start to Finish: The Creation of an Entire Computer from Motorola’s Cold Fire Processor Pyrotechnicians : Drew Larson Randy Jedlicka Josh Hudgins

Starting a “ Fire ” by using Smoldering Ashes Time: Fall 2000 Implementation of a Cold Fire System by Thai Luong, John Chenault, Greg Steglich The Protel Problem Current Status –Untested –Unevaluated –Unusable?

Objectives & Deliverables Develop working computer using the Motorola Coldfire Processor Evaluate the current status of the previously existing hardware designs Redesign (if necessary) Complete PCB layout with Protel Send designs off to have manufacturer fabricate PCB

Objectives and Deliverables (cont.) Mount all components onto board Port VxWorks to Flash Rom Test Completed design with Dumb Terminal Rewrite Labs for CPSC 462

Historical Points of Interest Spring Dr. Michel Lynch from the University of Florida Success spawns interest for Dr. Mahapatra of Texas A&M University Legendary “Group 5” desperately attempts recreation of Dr. Lynch’s system January 25th, Up and coming Pyromaniacs latch onto Cold fire project.
