[GreenKeys] Available Volpe USB to TTY Current Loop Board

[DAN BEACH]

I found one of Eric Volpe’s USB Serial to Teletype Current Loop Interface Boards in the back of a drawer as I was clearing out the last of my RTTY stuff. 
It is ver. 1.0, #012 and is as new, a spare. I’ll be happy to send it to anyone who can put it to use, at my expense.
