[GreenKeys] RTTY Interface

[Teletypeparts at aol.com]

Greetings to all,
 
I have a Hal Computer RTTY Interface, model CRI-200.  
 
I am looking for the manual for this unit.  Plans are to loop the audio thru 
it to my Hal ST-5000 and use the CRI-200 LED display to help tune the RTTY 
signal.  
 
Can I get some advice on the feasibility of this and does anyone have a 
manual or know where to get a copy of one?  I have no power supply for it, but hope 
the manual will help to identify what I need.  
 
If my plan is worthless, then I will give the interface away for shipping 
costs.  
 
Thanks,
 
Wayne
