Actually it is quite trivial. There is lots of digital decoding software
for the PC out there and morse code is one of the simplest forms of
digital encoding. Since probably 99% of all high speed code is machine
generated, either by computer or keyer, it's uniform enough to be
easily decoded.
A web search on "morse code decoding programs" found plenty, and
this is probably the cheapest device on the market:

Great, I will also search the web for others, as you suggested.

I can see I have quite a lot to catch up on. With any luck,
my books should arrive today at my rural post office.

Really looking forward to getting back, only hope my
ancient brain is up to the task.

Most of my neurons have mutated into morons,
my synapses have not snapped in ages. My brain has
shrunk so much that I am afraid to shake my head,
for fear of hearing a rattling noise.
