" In Philadelphia, a central computer system is used to program cartridges, which are inserted before the election into the voting machines. Those cartridges, after the election, are plugged back into the central system to tally the votes. The so-called "closed system," from the programming of the cartridges to the machines to the tabulation of votes, is not connected to the internet or other computers.
Stein wanted the computer code used in the central system to be copied and examined by her technical experts "

"But computer experts says the old electronic voting machines have a hidden flaw that worries them in the event of a very close election. The machines do not produce a paper ballot or receipt, leaving nothing to be recounted if the election outcome were in doubt, such as in 2000, when the nation awaited anxiously for Florida to reexamine those hanging chads.
“The nightmare scenario would be if Pennsylvania decides the election and it is very close. You would have no paper records to do a recount,” said Lawrence Norden, deputy director of the Brennan Center for Justice’s Democracy Program, co-author last year of a report on the risk posed by old voting machines.

"The Philadelphia city commissioners have agreed to recount some ballots cast in the city, as requested by Green Party presidential candidate Jill Stein, but rejected a forensic audit of how those voting machines work."

"With a few cursory clicks of a mouse, Appel parted with $82 and became the owner of an ungainly metallic giant called the Sequoia AVC Advantage, one of the oldest and vulnerable, electronic voting machines in the United States (among other places it’s deployed in Louisiana, New Jersey, Virginia and Pennsylvania). No sooner did a team of bewildered deliverymen roll the 250-pound device into a conference room near Appel’s cramped, third-floor office than the professor set to work. He summoned a graduate student named Alex Halderman, who could pick the machine’s lock in seven seconds. Clutching a screwdriver, he deftly wedged out the four ROM chips—they weren’t soldered into the circuit board, as sense might dictate—making it simple to replace them with one of his own: A version of modified firmware that could throw off the machine’s results, subtly altering the tally of votes, never to betray a hint to the voter.
