The memo, written by Orlando Suarez, head of the county's Enterprise Technology Services Department, describes Mr. Suarez's examination of the electronic record of the May 2003 election in one precinct. The ES&S machines in question provide two reports at the end of an election. One report, the "vote image report", gives the vote tabulation (i.e., number of votes cast for each candidate) for each voting machine, and the other gives an audit log of significant events, such as initialization of the machine and the casting of a vote (but not who the vote was cast for), for each machine.
