Morse Code Input, Ultimately want morse code to speech Options

[jfr]

I'm looking into the possibility of writing an app for the Z that would take Morse Code input, and speak the resulting text.

The beneficiary would be a 92-year-old friend who has been a life-long radio ham, and who through a series of strokes has lost the power of speech.

Ideally, it'd be possible to connect a real Morse key to the Z by some means, so that he could use his own morse key.

I've found links to this sort of stuff via google, but unfortunately the links are dead. There are references to a sourceforge project called zmorsed, and I've seen a reference (without a link) to "How to connect a real Morse key via the audio connector". That reference said it was possible, but didn't go beyond that. The sourceforge links all lead to an "Access Denied" response. (Yes, I was logged in at the time.)

My plan would be to use flite for the speech synthesis, driven by the program that I'd write. I've proved out the speech synthesis part, but it's the Morse Code input that's lacking.

I'd be really grateful if anyone could help out here. For starters, does anyone have the zmorsed source?
Or any other code for interpreting morse code? Ideas for connecting the morse key?

Cheers

John
