I got the first recording from ED-E after talking to old lady Gibson.
Following a walkthrough I found online, I next spoke to Ignacio Rivas
but I neglected to ask him about archimedes, which I found out way
later I was supposed to do. Since then I have spoken to Dr Henry and
got the third recording and went back to Rivas to talk to him again but
I can no longer get him to discuss archimedes.
I went on to talk to Quartermaster Hayes, Dr.Hildern and Michael Angelo
but still no second recording even after enough gameplay to advance
two levels. Before I have to use a previous saved game and lose a lot
of progress, is there anyone else to talk to or anything to do to get the
second recording out of ED-E?


n/m, I used the console command

to finish the quest.
