Hugh, thanks for posting. I've been working with some code to covert art
files to MP3s. Not as easy as you might think. I've taken your ascii
files and batched them to 5bit MP3s. Many ASCII characters don't
translate to the 32 character limitations so you get what you get. Both
170 and 850 shift. Do they work??? Beta test... Let me know! I plan on
adding many more, properly titled and indexed.
The files are at https://5bits.net third column near bottom.
73, John W1AN
