Computers have this wonderful facility called a "copy".

You mean, a "working" music Braille output for an ancient historical
version of LilyPond that does not compile on current systems, likely
runs limited to 32bit, has much worse programming features and has no
useful online support by current users and programmers because everyone
has moved on.

To get anywhere useful except for a single-shot project, you'll not get
around upgrading, and upgrading may make getting anywhere useful easier.
