[GreenKeys] Northern Radio Type 396 TTY test set

[Duncan Brown]

This cute little Northern Radio portable TTY test set showed up at the 
AWA Museum last week.  I have not been able to find anything on the 
Internet about it.

It has five TO-5 type ICs (only one I can read is "CD4004", no date 
code) and one 24 pin ceramic DIP with xtal time base.

I powered it on, but it didn't do much.  But I am not sure I understand 
how to hook it up and without a manual, don't want to damage it.  
Strange that it does not have a speed/baud rate control.

Does anyone know anything about it?


Thanks,

Duncan
