I own an ET-4000A (the 'later' 6802 based ET-4000), but not from vcfe. I 
don't own the ETA-4000 addon, though. And the dipswicthes on the ET-4000 
have been 'studented' half to death, so I should probably replace the array.
Does anyone have the "Speech Synthesizer" addon 'lesson' binder and 
chips for the ET-4000? If so, please contact me off-list.
