FS: Tono Theta 777 stand-alone multi-mode RTTY terminal unit TU
			 
			 
			
		
		
		
			
			For sale: I have a very interesting piece of equipment for transmitting 
and receiving rtty, amtor, cw, and ascii digital data modes. 
 
This is a rare Tono model Theta 777 multi-mode code converter. 
 
What separates this TU from any other is you connect it to any 'dumb 
computer terminal' to use as the I/O display! 
If you have an old dumb terminal laying around collecting dust, now's 
your chance to put it to good use! 
 
The Tono is a microprocssor controlled code converter that 
sends/receives data on it's rs-232 port and communicates directly with 
any rs-232 terminal. The Tono is completely controlled from the 
terminal, or you can run a terminal program and connect it to a pc if 
you wish. The unit runs on 12vdc. You will need to supply 
an AC adapter, or run it directly off your hf rigs 12Vdc supply. 
 
The unit works flawlessly on every mode, and cosmetically in close to 
new condition. 
I have a couple of pictures of the unit for anyone interested. Unit 
comes in its original box with manual, interface cable, and some pc 
terminal software on 3 1/2 and 5 1/4 inch floppys. Again, all you need 
is a dumb rs-232 terminal or a terminal program to run this unit.
