This article has a lot of good info about the process that will be used in the Windham, NH audit. Even though they don't have a lot of ballots (as evidenced by the 2 tables of boxes seen yesterday), the auditors expect the process to take ~4 weeks!
What was very interesting to me was the mention of the IBM 5150 chip knockoff. These machines are old! Plus, I could swear I had read where Donald Trump was looking for an IBM 5150 machine years ago. Of course I can't find where I saw that now.

Right now (Wednesday), the audit is being run by one company, Verified Voting, which has a long history of producing the result wanted by the top bidder. The NH patriots are still trying to get their own auditor as required by law, but have been stymied.
As of this morning, the four machines have been mothballed since November. This is valuable since it captures their state just after the election. The Patriots tried to get a restraining order so that they won't be turned on (which will change the state) before final state is captured.
