(*) There are several BASIC files that

    were last modified. The latest is
    October 28, 1982. The disk label
    also says (c) 1982.

This disk was automatically cracked by
Passport. Here is the transcript for
side A:

This is a very interesting result. I
was previously unaware of any disk that
used the E7 bitstream before Locksmith
5.0 (released in 1983). If this disk
was in fact released in late 1982, it
is the earliest known specimen of this
protection.

Quod erat liberandum.
