The text of the Eastern Orthodox Bible is available online as a .pdf here
The Orthodox New Testament is not available online, but you can purchase a searchable soft-copy on disc from the monastery that produces
it. The price is pretty crazy though.
I don't think the text of the Orthodox Study Bible Old Testament is available anywhere online. However, the New English Translation of the Septuagint (NETS) can be found here
Apostoliki Diakonia also has an online version of their Greek publication of the Scriptures here
