I doubt the -YA makes any significant difference
here.
...
Note that a -YA normally means it's just a board with a newer revision.
It do not normally means any change in functionality, except perhaps
some improvement. But in general totally compatible.
This might be the exception to that rule! Note the description "extra wires to
bring out clock & 110/300 speed change"; if one could in fact change the baud
rate _off the card_, there's probably some special magic in the interface (and
thus the cable). I suggest consulting 11/780 manuals to see how it was used.
