I did chuckle at that. Also, that many of the details that were
in the SAIC report before release by the state of maryland are given
in the Compuware report. Notable among these is the hard-coded PIN used
for supervisor access -- 1111, and they tried random guessing and got it
on their third try.

On the other hand, if I was building a voting system from scratch, as an
embedded system, I'd be strongly tempted to build it from a handful of
microcontrollers, each running exactly one software module, and with all
intermodule communications out in the open, as distinct data paths on
mother board. If I did that, I'd clock the microcontrollers at 16Mhz,
which for many such products, means that they'll be running code at

Slow processors aren't a real problem for voting, since we're not trying
to do gratuitous glitzy animation.
