I can't directly answer your question, but here is an idea:

The encoding cannot be that difficult, can it?  First compose a table
of the characters that appear in the encoding.  I'd bet that it uses
64 different characters, which yields a 4:3 expansion ratio.

Take the source code of uudecode or a BASE64 decoder as a starting
point, and replace the character table.  You need an encoded file and
a piece of known plaintext.  The Bit Machinator program serves both
purposes: you already have the encoded file, and the plaintext
probably starts with the bytes 01 08 xx 08, the beginning of a BASIC

If you provided a link to the encoded representation of the program,
you could get some reverse engineering assistance from me and others
on this list.
