Beta is easy, I can help you with that.
Which patch version of the beta do you want?
1.00
(1.01, 1.02 <- Only patch notes for these)
1.03
1.10
1.11
1.12
1.13
1.20
1.21
1.30
1.31
1.32
1.33
1.34

Alpha is more difficult, since alpha means August 1999 - December 2001
But I think I can help you with that one, too.
