Schematics of Atanasoff-Berry Computer logic circuits?

[William Blair]

Does anyone know of a source for schematics of the Atanasoff-Berry Computer vacuum tube logic circuitry?  I've found this web page:

http://www.scl.ameslab.gov/ABC/

but there are no schematics available there.  I have emailed the person at the bottom of the web page, but I suspect that since school is not in session, I won't soon get a response.
