HI All
I was out messing around today and started fiddling with a TT/L-2 that I 
found.
I was wondering if any one could give me any insight on how this would hook 
up.
I am afraid to try it with out some input from someone. I did find some 
diagrams on
RTTY.com but would like a suggestion before I blow something up.I was about 
8 or
9 when this was built and it looks like he winged it some. Here is a picture 
of the unit.
The box to the left connects into the back for the printer and I think the 
keyboard.
I have tried to draw a diagram of the connector I hope it turns out.
>From left to right they are AUD, GND, S, M, 5V ttl, 6V ac, SKUR, FSK
You can see a photo at http://www.projectgm.com/ttl_2_1.html
Thanks in advance for the help I just hate to see this old stuff go to 
waste.
Thanks
Gerald
