I've got an ancient BASIC translator around somewhere. But it's not a 
simple 5/8ths as you have to use the LTRS and FIGS characters to 
signal switching from alpha to numeric/punctuation or vice versa.

That adds some overhead. Perils of an overly limited character set 
(26 letters plus space, CR, LF, NUL, FIGS,  & LTRS)

Not nearly as bad as Cyrillic baudot with three level shifting 
instead of two level.

Baudot should compress a bit better, since it throws away case info.
