This is actually a group of Apple Macintosh computers in O.I.T.'s Student Labs at Queens College, City University of New York. SETI is run when the lab is closed, or the machines are unused. Originally all of the computers were 6214 performas.
I am now running it on :
20 933MHz G4s with 512MB memory
20 350MHz G3s with 256MB Memory (B&W)
20 300MHz G3s with 256MB Memory (Beige)
30 500MHz G3s with 512MB memory (iMacs)
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
