Um, excuse me - do you mean records morse and then allows you to dump it
into your computer?  Off-air morse readers exist, check out popular
electronics magazines with a comm bent - maybe 73, QST or Monitoring
times as well.  

But recording it?  And audio playback? How about a microcassette
recorder and a code practice oscillator in the pocket?  Shouldn't run
more than $20.00 and take next to no construction.  You could even dump
it onto your computer through the above interface.

Of course you _could_ simply go for the microcassette and (radical
idea!) actually speak into it - and then PLAY IT BACK when you have time
to type the ideas on the computer.  It's called "dictation" and there
used to be workers called "stenographers" who used to make a living
doing this for others.

Oops.  I forgot.  We're all hardware hackers here.  Okay, make the CPO
with a breadboard and a 555 timer and a 9v. ;)
