Now I was in position to search emails looking for people who had been in contact with Motorola. My first lead was an email to an Intermetrics engineer named Marty Stolz, who had received a message from someone at Motorola explaining a problem they were having with the compiler. I hacked into Stolz’s workstation and examined his "shell history," which showed a list of commands he had previously typed. He had run a particular program, a "shell script" called "makeprod," which he had used to build compiler products that the company developed. In this case, I wanted the 68HC11 compiler so I could compile the Motorola source code for the MicroTAC Ultra Lite.
