Nice puzzle! I like how it takes a few steps to get the result. :-) My approach was perform "run length encoding" on the dots and dashes, encode the pattern into an integer (in binary, with a start bit), and then look it up in a ROM .

Although it's a little bit annoying that the outputs are simple outputs, so they clip at 100 degrees. At least my solution would work with only minimal modifications with the outputs as x-bus instead.

Wow, though puzzle, had me tinkering for a while, thank you!
