Both machines were on the fritz as polls opened at St. Andrew's Lithuanian Church, 19th & Wallace Streets, in the city's Spring Garden neighborhood.
The polls, five blocks from outgoing state senator Vince Fumo home, are in the 16th division, 15th ward.
Early voters were asked to fill out provisional ballots. More than 20 people did so and left grumbling when they learned their ballots wouldn't be counted tonight.
By 7:30 a.m. election workers got the two machines up and running on batteries.
